If you love growing plants, you already know that choosing the right container matters just as much as the soil or sunlight. A best rectangular wooden planter box does more than hold dirt – it affects root health, water drainage, and how your plants grow over time. Whether you are setting up a windowsill herb garden, a raised bed for veggies, or a decorative flower box for your patio, the shape, wood type, and drainage features all play a role in keeping your plants thriving. In this guide, we look at 10 popular rectangular wooden planter boxes available in 2026 to help you pick one that matches your space and gardening style.
Many gardeners struggle with planters that rot too quickly, hold too much moisture, or look plain after a season. Rectangular wooden planters offer a classic, natural look that fits most gardens, but not all are built the same. Some use treated wood for weather resistance, while others rely on liners or drainage holes to prevent root rot. If you are shopping in October of 2026, you will find options ranging from $$16.99 to $$157.60, with brands like Giantex, NatraHedge, THYOI and more offering different sizes and styles.

Pros
- Exceptional value for the price, often exceeding expectations
- Quick and straightforward assembly, taking around 30 minutes
- Attractive light brown color with decorative details
- Versatile size suitable for patios, yards, greenhouses, and porches
- Good drainage design with bottom slat spacing and drainage holes
Cons
- Wood is softer than some pricier options, may not last as long in harsh weather
- No liner included; bottom slats have gaps that can let soil spill out
- Some units may have minor splits in decorative corner pieces
The Yaheetech 43.5" L x 16" W x 14" H Wooden Raised Garden Bed is a solid, budget-friendly planter that blends practicality with nice looks. It is made from fir wood and designed for growing vegetables, flowers, or herbs in backyards, patios, greenhouses, or on porches. With a generous inner space of about 40.4" by 12.6" by 9", you get enough room for several plants without taking over your outdoor area. This planter is especially good for beginner gardeners or anyone wanting an affordable way to start raised bed gardening.
What stands out most is how easy it is to put together. Many reviewers mention assembly taking under 30 minutes, thanks to single-piece side plates that fit together without fuss. The wood has been sanded smooth, so you won’t deal with splinters, and the light brown color with decorative corner posts gives it a charming, rustic appearance. Drainage holes and the spaced bottom slats help prevent waterlogging, though you may want to add a liner if you’re putting it on a deck or porch to avoid soil stains. Real users consistently praise the value, saying it looks and feels much more expensive than it is.
Build quality is good for the price, but it’s worth noting the fir wood is on the softer side. Some buyers have reported that the decorative crown details can split slightly, and the bottom gaps do allow some soil to fall through. That said, the planter feels sturdy enough for typical soil and plant loads, and weather-resistant treatment helps it hold up through a season. If you want heirloom durability that lasts decades, you’d need to spend more. But for a few years of reliable use, this Yaheetech bed is a smart choice.
Overall, the Yaheetech raised garden bed delivers exactly what most home gardeners need: a good-sized, good-looking planter that assembles fast and doesn’t break the bank. It is practical for growing herbs, peppers, flowers, or lettuces, and its height makes it easy to tend without bending too much. If you’re looking for a straightforward, low-cost introduction to raised bed gardening, this model is hard to beat.
Pros
- Naturally water-resistant acacia wood with protective finish.
- Includes plastic liners to keep the wood clean and dry.
- No pre-drilled drain holes prevent accidental water spills on surfaces.
- Set of two provides flexibility for styling and planting.
- Lightweight and portable for easy repositioning.
Cons
- No pre-drilled drainage holes (must add yourself if required).
- Small size (17x4x4 inches) limits plant choice to small herbs and succulents.
- Only available in natural wood finish; no color options.
- Zero customer reviews yet, so real-world durability is unconfirmed.
The zaqro Indoor Planter Box Set of 2 is a pair of compact acacia wood planters designed for windowsills, countertops, and other narrow surfaces. Each planter measures 17 by 4 by 4 inches, making them ideal for small herbs like basil, mint, or parsley, as well as succulents and tiny flowering plants. This set is especially suited for apartment dwellers or anyone looking to add a touch of greenery to a kitchen or office without taking up much space.
The standout feature here is the use of acacia wood. It’s a dense hardwood that naturally resists moisture, and zaqro applies a protective finish to boost durability indoors. The planters have reinforced corners to keep their shape over time. Each box comes with a custom plastic liner that fits snugly inside. This liner acts as a barrier between soil and wood, so you don’t have to worry about rot or staining. If you prefer to have drainage, you can drill holes into the plastic liner (and the wood if desired) to suit your plants’ needs.
Design-wise, the natural wood grain gives these planters a clean, warm look that blends with most decors. They are lightweight, making it easy to shift them from a sunny window to a shady spot as needed. The set of two allows for symmetrical placement on a long sill or separate use on different tables. Since the default configuration has no drain holes, you can water plants directly on wood surfaces without fear of leaks or water rings.
One honest drawback is the lack of pre-drilled drainage holes. While this prevents messes, some plants require good drainage to thrive. You’ll need to modify the liner (and possibly the wood) if that’s the case. The small size also means these planters won’t hold large plants or multiple specimens comfortably. Additionally, with no customer reviews yet, it’s hard to gauge long-term performance, though the materials and build seem solid for the price.
Overall, the zaqro planter set offers a tidy, attractive solution for indoor herb gardening or decor. The natural acacia wood with protective liners balances style and practicality. If you need compact, no-fuss planters for a windowsill or countertop, this set delivers good value. Just be prepared to add drainage holes if your chosen plants demand them.
Pros
- Attractive rustic design with a natural wood grain appearance
- Plastic liner prevents water damage and makes cleanup easy
- Lightweight and easy to reposition around the home
- Versatile for plants, candles, or decorative arrangements
Cons
- No drainage holes in the box or liner, which may lead to overwatering if not modified
- Some users report the wood feels thin and may not hold up outdoors
- Small size may not suit larger plants or those needing deep soil
The Windiy Rustic Wooden Planter Box is a narrow rectangular box designed for small plants and decorative arrangements. It measures 17.3 inches long by 3.9 inches wide and tall, making it a good fit for windowsills, mantels, or tabletops. This planter is aimed at those who want a farmhouse or rustic look for succulents, air plants, or even candles and mason jars.
The standout feature is the removable clear plastic liner, which helps contain soil and water to prevent leaks. This makes the box suitable for indoor use without worrying about damaging surfaces. The wood is made from natural aged pine with a warm brown finish, giving it a charming, country feel. The bottom is smooth to avoid scratching furniture.
In real-world use, the planter is lightweight and easy to handle, but some users note the wood feels thin and may not be durable enough for outdoor exposure. The lack of drainage holes is a common concern, though some buyers have cut holes in the liner to improve drainage. It works best for dry environments or plants that don't need much water.
Design and build quality are mixed. While many appreciate the aesthetic and find it sturdy enough for indoor display, a few reviews mention the wood can be flimsy or that the box is smaller than expected. It's best suited for decorative purposes rather than heavy gardening.
Overall, the Windiy planter is a good choice if you need a rustic, lightweight container for small plants or table decor. Just be aware of its limitations with drainage and outdoor use. It's a solid option for farmhouse-style interiors or as a gift for casual plant enthusiasts.

- Solid acacia wood construction feels premium and durable
- Easy 5-10 minute assembly with pre-drilled holes
- Removable plastic tray prevents leaks, great for indoor use
- Includes hanging hooks for flexible placement options
- Compact size works well on small decks, balconies, or tabletops
Cons
- Smaller than many expect; interior is only about 13" x 4.5" x 5", best for small pre-potted plants
- No included liner for direct soil planting, and finding a custom fit liner can be challenging
- Some users report minor warping after prolonged outdoor exposure, though this is typical for wood planters
The THYOI Premium Wooden Planter Box is a compact, rustic crate designed for plant lovers who want a stylish way to display small flowers, succulents, or herbs. Made from acacia wood with a waterproof finish, it works both indoors and outdoors, though it's best suited for pre-potted plants rather than direct soil planting. This is a great pick for anyone looking to add a touch of natural warmth to a deck, balcony, or window sill without taking up too much space.
In real-world use, this planter shines as a decorative piece. The golden walnut finish gives it a rich, warm look that complements most decor styles. Assembly is a breeze, with pre-drilled holes and large screws that let you put it together in about 5 to 10 minutes. The included plastic tray is a thoughtful touch, preventing water from dripping onto surfaces when used indoors. The two steel hooks are a bonus, allowing you to hang the box on a wall or fence for vertical gardening. However, note that the interior dimensions are smaller than the exterior suggests, so it's not ideal for large plants or direct soil gardening without a custom liner.
Build quality is solid for the price. The acacia wood feels sturdy, and the thick feet provide a stable base that can hold up to 22 pounds. Some users have mentioned slight warping after a year outdoors, but that's common for wood planters exposed to the elements. The waterproof coating helps, but you might want to bring it inside during harsh winters to extend its life.
On the downside, the size can be a surprise. At 17 x 6 x 5.5 inches, it's smaller than many expect, and the interior is even more compact due to the construction. If you're looking for a planter to directly hold soil and multiple plants, this might not be the best fit. Also, while the hooks are handy, they're best for lightweight use.
Overall, the THYOI planter box is a well-crafted, versatile option for those who need a small, attractive container for pre-potted plants or as a rustic storage box. It's easy to assemble, looks great, and offers flexible placement. Just be sure to check the dimensions and plan to use it with pots or a liner for the best experience.
Pros
- Realistic wood grain appearance without yearly staining or sealing
- Integrated watering system reduces plant care frequency
- Lightweight at 17.6 lbs yet sturdy for large plants
- Quick and easy tool-free assembly
- Flexible drainage options for both indoor and outdoor use
Cons
- Resin material may not feel as premium as natural wood
- You may need to drill drainage holes yourself if desired (optional)
- 37-gallon size and 21.7-inch height may be too large for smaller spaces
The Keter Signature planter delivers a convincing wood grain appearance without the upkeep of natural wood. Designed for both indoor and outdoor use, it's a great option for homeowners who want a large, attractive planter for their porch, patio, or garden without worrying about weather damage.
Standout features include a 37-gallon capacity and integrated water reservoir that helps prevent overwatering. Assembly takes only about 5 minutes, and the lightweight resin material (17.6 lbs) makes it easy to move. The optional drainage holes add flexibility for different plant types.
The rosewood finish and clean, modern lines will complement many decor styles. While the resin feels sturdy, some may prefer the weight and texture of real wood. Its size (30x18x21.7 inches) is substantial, so it works best on a deck or patio corner rather than a cramped balcony.
If you want the look of wood without the maintenance and need a planter that can handle larger plants or a dense flower arrangement, this is a solid choice. Just be aware you might need to drill your own drainage holes if that's a priority. Overall, it offers excellent value for a low-maintenance planter.
Pros
- High-quality acacia wood and sturdy construction for the price.
- Quick and straightforward assembly with pre-drilled holes and clear instructions.
- Versatile use as a planter, storage box, or decorative accent for indoor and outdoor spaces.
- Waterproof finish and drainage slots help plants thrive while protecting surfaces.
- Compact size perfect for small decks, balconies, or countertops.
Cons
- Smaller than many expect; interior dimensions are about 13 x 4.5 x 5 inches, ideal for small pre-potted plants only.
- No soil liner included, so you'll need to use pots with a tray or purchase a separate liner if planting directly.
- Some users report minor wood warping after a year of outdoor exposure, though this is typical for wood planters left in the elements.
The THYOI Premium Wooden Planter Box is a compact, rustic rectangular planter made from solid acacia wood. With external dimensions of 17 inches long, 6 inches wide, and 5.5 inches tall, it's designed for small spaces like window sills, apartment balconies, or desk tops. It comes in three attractive finishes: Natural, Golden, and Walnut. This planter is best suited for pre-potted plants or as a decorative storage box rather than for direct soil planting, though it can be adapted with a liner.
Build quality is impressive for the price. The acacia wood is smooth to the touch and the joints are reinforced with large screws for added sturdiness. The wood is pre-treated with a stain that enhances the natural grain and provides a waterproof barrier. The removable plastic tray at the bottom catches any excess water, making it safe for indoor use without damaging surfaces. The included steel hooks allow you to hang it on a wall or fence, offering flexibility beyond floor placement. Assembly takes around 5 to 10 minutes following the included instructions, with all holes pre-drilled.
In real-world use, this planter box works best for small succulents, herbs, or small flowering plants in their own pots. The interior dimensions (approximately 13 x 4.5 x 5 inches) limit how many pots you can fit, but for a single small plant or a couple of tiny pots, it's very effective. The stackable design is a nice bonus if you order multiple boxes, allowing you to create tiered displays. However, keep in mind that the wood may warp slightly over time if left outdoors in rain or direct sun year-round, as noted by one long-term reviewer.
A minor drawback is the lack of a soil liner. If you plan to plant directly into the box, you'll need to buy a separate plastic or fabric liner that fits the interior dimensions, which can be tricky to find. Also, the size is smaller than some shoppers expect, so double-check the dimensions before buying. The waterproof finish and drainage slots work well, but over time, wood exposed to the elements will naturally show some wear.
Overall, the THYOI Wooden Planter Box is a solid choice for anyone who wants an attractive, well-made small planter or storage box for indoor or covered outdoor use. It's especially great for renters or small-space dwellers looking for a rustic touch without sacrificing quality. Just make sure you understand the size and plan to use it with pre-potted plants or purchase a liner for direct planting. With easy assembly and a charming design, it's a practical and affordable option for adding greenery to your home.
Pros
- Very easy to assemble with clear instructions
- Attractive wood grain and classic styling
- UV-resistant treatment helps it endure sun and weather
- Versatile size works for flowers, herbs, vegetables, or small shrubs
- Good drainage system prevents waterlogging
Cons
- Some units arrive with split wood or missing internal supports for the bottom
- Plastic liner’s drainage holes may need enlarging for faster water flow
- Wood can crack if screws are over-tightened; handle with care
The NatraHedge Hampton Classic planter box is a straightforward, well-designed wooden planter that aims to simplify gardening for everyone. It comes in a generous 44-inch length, 15-inch width, and 15-inch height, giving you plenty of space for cut flowers, herbs, vegetables, or even a small privacy screen. The brown cedar finish gives it a warm, natural look that fits right in on a porch, deck, or indoor sunroom.
Assembly is genuinely quick around ten minutes if you follow the included instructions. The panels connect using a mortise-and-tenon joint system, and all screws and a black plastic liner are included. You only need a Phillips screwdriver. Many reviewers praised how easy it was to put together, often noting the clean fit of the wood pieces. The hemlock wood feels solid and has visible grain that adds character.
One standout feature is the UV-inhibitor treatment, which helps the planter resist fading and cracking from sun exposure. The raised feet keep the box off wet surfaces, and the slatted base allows air to circulate beneath the liner. The plastic liner itself is perforated for drainage, though some users found the holes too small and enlarged them for better water flow. That’s an easy fix if you want faster drainage for heavy soil or frequent rain.
Durability is rated at 3 to 5 years, which is reasonable for wooden planters exposed to the elements. A few reports of wood splitting during assembly or arriving with cracks suggest that quality control can vary. If you get a perfect unit, it’s a great value. The box is lightweight enough to move when empty but stable when filled with potting mix and plants. Some users added extra support straps for heavy loads, but most found the construction adequate for typical gardening use.
Overall, the NatraHedge Hampton Classic planter box delivers on its promise of easy assembly and classic style. It’s a solid choice for hobbyists and serious gardeners alike who want a durable, attractive planter for year-round use. Just inspect all parts upon arrival and handle screws with care to avoid splitting. With a little attention, this planter will serve you well for several seasons.
Pros
- Solid wood build with protective finish ensures long-term durability outdoors.
- Drainage system and convertible bottom give flexibility for different plant types.
- Easy to assemble thanks to slotted leg design and clear instructions.
- Attractive design complements any outdoor or indoor setting.
- Elevated height reduces strain on back and knees during gardening tasks.
Cons
- Interior depth of 9.5 inches may be shallow for large root vegetables unless converted to open-bottom.
- Natural wood may require occasional re-sealing to maintain appearance over years of exposure.
- No included soil or plants; you'll need to purchase those separately.
The Giantex Wooden Raised Garden Bed is a solid choice for anyone looking to start a container garden on a patio, balcony, or small backyard. Made from natural fir wood with a waterproof painted finish, this elevated planter measures 36 inches long by 16 inches wide and stands 15 inches tall. It's designed for flowers, herbs, vegetables, and even small fruits, making it a versatile addition to urban gardening setups.
One standout feature is the base with five drainage holes that help prevent water buildup and reduce the risk of root rot. Even better, the bottom panels are removable, so you can convert this raised bed into an open-bottom planter for plants that need deeper soil. That flexibility means you can switch between shallow-rooted herbs and deeper-rooted veggies like tomatoes or peppers with minimal fuss.
The build quality is impressive for the price. Fir wood is naturally sturdy, and the painted coating adds weather resistance. Decorative corner moldings and X-shaped side panels give it a polished look, while rounded edges help avoid accidental scrapes. Assembly is straightforward thanks to slotted legs that lock into place, though you'll need a screwdriver and a bit of patience. Most users can put it together in under 30 minutes.
One potential drawback is the interior depth. With only 9.5 inches of soil space when using the bottom panels, deep-rooted plants might feel cramped unless you remove the panels. Also, while the paint helps, outdoor wood will eventually weather and may benefit from an annual coat of sealant to keep it looking fresh. That said, for the price and versatility, these are minor trade-offs.
Overall, this Giantex raised garden bed is a practical, attractive solution for small-space gardening. It's easy to assemble, offers great drainage, and adapts to different plants. If you're looking for a sturdy planter that doesn't require a lot of space or maintenance, this one is well worth considering.
Pros
- Removable plastic liners protect the wood and simplify replanting.
- Slim, space-saving size fits narrow windowsills and ledges.
- Rustic design looks great in a variety of decor styles.
- Two-pack offers good value and a coordinated look.
- Lightweight and easy to reposition.
Cons
- No drainage holes in the wooden boxes; the plastic liners may need to be modified for proper drainage.
- Wood finish may not hold up well to heavy outdoor rain or direct sun over time.
- Size is best suited for small plants; larger root systems may be cramped.
The oyhqes Wood Window Box Planter set includes two rectangular wooden planters that bring a touch of rustic charm to any indoor space. Designed for windowsills, narrow tabletops, or even a kitchen counter, these planters are a practical choice for growing herbs, succulents, small flowers, or decorative greenery. The set is ideal for plant lovers who want a neat, organized look without taking up too much room.
Each planter comes with a soft, removable plastic liner that sits inside the wooden box. This liner is a smart addition because it protects the wood from moisture and soil stains, making it easier to swap out plants or clean the container. However, the liners do not have pre-cut drainage holes. You can cut holes or slits into the plastic yourself to allow excess water to escape, which is essential for most plants. Without drainage, you risk root rot if you overwater.
The build quality is decent for the price. The wood has a nice rustic finish that fits well with farmhouse, modern, or boho decor. At 17.3 inches long, 3.9 inches wide, and 3.9 inches tall, each planter offers enough space for a few small plants but may feel tight for larger root systems. They are lightweight, around 1.1 pounds each, so you can easily move them around as needed. Keep in mind that the wood is not treated for heavy outdoor exposure; these are best used indoors or on a covered porch.
On the downside, the lack of pre-drilled drainage holes in the wood or liners means you will need to do some DIY if you want proper water flow. Also, the wood may warp or discolor if left in direct rain or intense sun for long periods. The size is specifically for compact spaces, so if you are looking for large statement planters, this set might feel too small.
Overall, the oyhqes Wood Window Box Planter set is a solid, budget-friendly option for adding a touch of greenery to tight spots. The removable liners make maintenance simple, and the rustic design looks inviting. Just plan to add your own drainage holes and keep them mostly indoors. For windowsill herb gardens or small succulent arrangements, these planters deliver style and function without fuss.
Pros
- Easy and quick assembly process, as noted by many users.
- Attractive rustic cedar brown finish that enhances outdoor decor.
- Functional drainage system to prevent overwatering.
- Slim profile fits perfectly on railings, windowsills, or narrow garden strips.
- Solid wood construction offers good stability for its price point.
Cons
- Bottom panels are thin and some users report concerns about potential rot without additional waterproofing.
- Occasional minor assembly issues like misaligned pre-drilled holes or missing screws.
- The loose-bottom design means it's best used with soil directly or as a pot holder, not as a sealed container.
The Giantex Raised Garden Bed is a straightforward solution for gardeners dealing with limited space. It's a long, rectangular wooden box made from fir wood, finished in a warm cedar brown. This planter is perfect for anyone looking to add a burst of flowers to a window ledge, line a patio railing, or create a small vegetable patch in a tight corner of the yard. Its narrow 13-inch width is the key to its versatility.
Performance-wise, it serves its purpose well as a decorative container. The two drainage holes at the bottom are a practical feature, helping excess water escape to keep your plants' roots healthy. Many users found assembly incredibly easy, often completing it with just the included screws. You can fill it directly with soil for planting or use it as a stylish holder for individual pots, which adds to its flexibility.
The build quality centers on its natural fir wood construction. The frame pieces are solid and provide good durability for the structure. However, feedback highlights a common concern: the bottom boards are quite thin. Some reviewers successfully mitigated this by applying a waterproofing sealant inside and out to prolong the planter's life, especially for outdoor use. The color is a consistent cedar brown, though a few noted it leans slightly orange.
A couple of drawbacks are worth mentioning. While assembly is generally simple, a few boxes had minor issues like pre-drilled holes that didn't align perfectly, making corners less square. Also, the bottom is not a sealed panel, so if you're using it with loose soil, it functions as intended, but it isn't a completely enclosed 'pot' as some might expect. It's more of an open-frame planter.
The final verdict is that this Giantex planter is a solid value-for-money option for its specific niche. It's not a heavy-duty, permanent garden bed, but it's an excellent, attractive container for seasonal flowers, herbs, or shallow-root veggies. If you're willing to do a quick assembly and maybe add a coat of sealant for extra protection, it will bring a lovely touch of green to your compact space for seasons to come.

Consider your primary use. This planter works best for decorative flowers, herbs, or vegetables with shallow root systems. Its depth is suitable for many common garden plants but not for deep-rooting crops.
For outdoor placement, applying a wood sealant or waterproofing treatment to the interior, especially the bottom boards, can significantly increase its longevity and prevent early rot from constant soil moisture.
Assembly is straightforward, but have a drill or screwdriver handy. Check all pieces and screws upon opening. While most kits are complete, having a few spare similar screws (approx. 2-inch) can save a trip if one is missing.
Due to its long, narrow shape, it's ideal for lining fences, windows, or deck edges. Ensure the surface is stable and level. It's lightweight, so you can move it if needed, but fill it with soil or pots after placing it in its final spot.
Remember the bottom has drainage holes but is not a sealed container. You can plant directly into it with soil, or use it as a handsome frame for existing potted plants. This flexibility is a key feature.
Frequently Asked Questions About Rectangular Wooden Planter Boxes
Here are some common questions gardeners ask when shopping for a best rectangular wooden planter box.
What size rectangular wooden planter box is best for herbs?
For herbs like basil, mint, and chives, a planter around 17 to 24 inches long and 4 to 6 inches deep works well. Many indoor gardeners prefer the THYOI Premium Wooden Planter Box (17″ L) because it fits neatly on a windowsill and comes with a plastic liner to protect the wood. Deeper boxes, such as the Giantex Raised Garden Bed, are better for root vegetables or larger plants.
Do rectangular wooden planter boxes need drainage holes?
Yes, drainage holes are important for most plants to prevent waterlogged soil and root rot. Some wooden planters come with pre-drilled holes or a slatted base, like the NatraHedge Hampton Classic which has a perforated plastic liner. If a planter does not have holes (like the Winlyn Rustic Wooden Planter Box), you can use the removable plastic liner to add your own or use it as a decorative cachepot with a separate pot inside.
Which wood type is most durable for outdoor rectangular planters?
For outdoor use, acacia wood and Canadian hemlock are naturally more resistant to moisture and rot. The THYOI boxes are made from acacia and come with a wood stain finish, while the NatraHedge uses hemlock with a plastic interior liner. Fir wood, used in the Giantex and Yaheetech planters, is also durable but may require sealing for long-term outdoor exposure. You can compare more options in our best concrete flower basket planter article for alternative materials.
Can I use a rectangular wooden planter box indoors without a liner?
It is possible, but moisture from watering can stain or warp the wood over time. Most indoor planters, like the zaqro Indoor Planter Box Set, come with a removable plastic liner to keep the wood dry. If your planter lacks a liner, placing a shallow saucer or using a pot inside the box helps protect the wood. For more tips on indoor gardening, visit our plant care category.
How do I prevent a rectangular wooden planter from rotting?
Rot usually happens when wood stays wet for long periods. To extend the life of your planter, choose one with raised feet or a slatted base for airflow, like the NatraHedge or Giantex Elevated Raised Garden Bed. Applying a water sealant annually can also help. If you are using the planter directly in soil, an open-bottom design (like the Giantex convertible model) allows excess water to escape. For more durable options, see our best large plastic flower planters guide.
