15 Best Organic Fertilizer for Rubber Plant 2026 Insights Without Stress Growth

The Aquatic Arts Indoor Plant Food is a liquid all-purpose fertilizer designed to keep your houseplants thriving. With a balanced 3-1-2 NPK ratio, it delivers the key nutrients most indoor plants need for healthy growth. Whether you're caring for a fiddle leaf fig, peace lily, or a collection of succulents, this concentrate can be mixed with water and used in your regular watering routine. It's especially helpful for plants that look tired, have yellowing leaves, or just aren't growing as they should.

What sets this fertilizer apart is its fast-acting liquid formula. Unlike slow-release spikes or granules, the nutrients are immediately available to the roots. Many users report seeing greener leaves and new growth within a week of consistent use. The 3-1-2 ratio is well-suited for a broad range of common houseplants, promoting strong roots, lush foliage, and even more blooms in flowering varieties. It's also gentle enough to use regularly without burning plants, as long as you follow the dilution instructions.

In real-world use, this product has earned a strong reputation. The bottle is compact and easy to store, and the measuring cap makes dosing simple. The liquid has a mild, pleasant smell - not the harsh chemical odor you might expect. One 8-ounce bottle can last up to a year if you're feeding a few plants weekly. Customers consistently praise its effectiveness, especially for reviving struggling plants like fiddle leaf figs and helping them bounce back with new leaves and stronger stems.

There are a couple of drawbacks to keep in mind. Some buyers received bottles with missing or loose caps during shipping, which is more of a packaging concern than a product flaw. Also, the manufacturer recently changed the formula, and the liquid color shifted from milky white to a clear blue-green. While the new formula works just as well, the change wasn't clearly communicated, which caused some initial hesitation among loyal users. Over-fertilizing is always a risk with any concentrate, so be sure to measure carefully.

Overall, the Aquatic Arts Indoor Plant Food is a reliable, affordable choice for any indoor gardener. It's versatile enough for a wide variety of plants, easy to use, and delivers noticeable results. If you're looking for a straightforward all-purpose fertilizer that won't break the bank, this is a solid pick. Just double-check the bottle cap when it arrives and start with the recommended dosage to keep your plants happy and healthy.

Dr. Earth Exotic Blend is an organic granular fertilizer formulated specifically for palms, tropicals, hibiscus, ferns, and other exotic plants. It uses a 5-4-6 NPK ratio and includes TruBiotic technology, a blend of beneficial soil microbes and mycorrhizae that help plants absorb nutrients more efficiently and resist drought stress. This product is ideal for gardeners who want a natural, handcrafted feeding option that avoids synthetic ingredients and GMO byproducts.

The standout feature here is the microbial boost. Real-world users consistently note faster leaf development and bigger, more abundant blooms within weeks of application. For example, one reviewer saw a prayer plant unfurl new leaves in days, while another finally got a stubborn hibiscus to bud after a year. The formula releases nutrients quickly but continues feeding for months, making it a convenient choice for both container plants and in-ground beds.

Application is simple: rake back mulch, sprinkle the granules, and mix into the top soil. The bag covers 60 square feet or 16 five-gallon pots, offering good value for the price. However, be prepared for a pronounced fishy odor that can linger, especially if used indoors. Several reviewers mention their dogs trying to eat the fertilizer, so take precautions to keep pets away until it's well covered. Additionally, if you just sprinkle it on top of potted plants without mixing, you may see white mold growth, but that's harmless and easily corrected by stirring the soil.

In short, Dr. Earth Exotic Blend delivers on its promises: healthy, vibrant plants and prolific blooms. The organic ingredients and microbial additives set it apart from synthetic fertilizers. Just weigh the smell and pet-friendliness against the outstanding results. For most tropical plant enthusiasts, the benefits far outweigh the drawbacks.

The Purived 16oz All-Purpose Liquid Plant Fertilizer is a super-concentrated, odorless plant food that delivers serious value. One bottle makes 50 gallons of nutrient-rich solution. That means you get months of feeding for indoor houseplants, all from a single purchase. It's designed for a huge range of plants, including snake plants, pothos, succulents, monstera, and more.

One potential drawback is that it needs weekly application for best results, which may be more frequent than some granular options. Also, while it is all-natural, it is not certified organic, which could matter to purists. The capful-per-gallon ratio is easy, but if you are only mixing small amounts, you might need to measure carefully.

Overall, the Purived 16oz All-Purpose Liquid Plant Fertilizer is a solid choice for indoor plant enthusiasts who want an effective, convenient, and cost-efficient feed. It delivers balanced nutrition, works with many feeding methods, and is gentle on the environment. If you're looking for a reliable liquid fertilizer that goes a long way, this one is worth trying.

Fox Farm Big Bloom Liquid Plant Food is an organic bloom fertilizer designed to support flowering and fruiting plants throughout their entire life cycle. Made from earthworm castings and bat guano, it provides a gentle yet potent nutrient blend that feeds roots directly. This product is ideal for gardeners who prefer natural solutions and want to encourage bigger blooms and more abundant harvests without harsh chemicals.

The standout feature of Big Bloom is its immediate nutrient absorption. Because it's a liquid, plants can access the nutrients right away, leading to visible improvements in growth and flowering. The formula is safe to use on seedlings, mature plants, and everything in between, making it a versatile addition to any garden. Users appreciate the simple mixing instructions: just add 4 tablespoons per gallon of water every other watering, and you're set. It also works with hose-end sprayers and drip irrigation systems for larger areas.

In terms of build quality, the product comes in a sturdy 1-pint bottle with clear labeling. The liquid is dark and has a natural earthy smell, which is expected from organic ingredients. While the 1-pint size is convenient for small to medium gardens, heavy users might wish for larger options. Also, the NPK ratio is low (0-0.5-0.7), so if you're growing heavy feeders like tomatoes or peppers, you might need to supplement with additional fertilizers. That said, for most flowering plants and houseplants, this provides just the right gentle boost.

A potential drawback is the lack of customer reviews at the time of this writing. The product has a high rating of 4.7 stars, but without written feedback, it's harder to gauge real-world experiences. However, FoxFarm is a well-respected brand in the gardening community, and their other fertilizers receive strong reviews. The absence of reviews is likely due to it being a newer listing rather than a reflection of quality.

Overall, Fox Farm Big Bloom is a reliable organic fertilizer that delivers on its promises. It's easy to use, effective, and safe for a wide range of plants. If you're looking for a natural way to boost flowering and fruiting, this is a solid choice. Just be mindful of your specific plant needs and consider the size before buying.

If you're looking for a simple, organic way to feed your indoor jungle, Espoma's Indoor Plant Food concentrate is a solid choice. This liquid fertilizer is designed for a wide range of houseplants from small succulents and pothos to larger fiddle leaf figs, monsteras, snake plants, and palms. The organic formula is made from natural ingredients and is explicitly labeled safe for use around children and pets, which is a big plus for households with curious little ones or furry friends.

The standout feature here is convenience. One 8 ounce bottle makes up to 16 gallons of plant food when mixed at the recommended rate: half a cap per quart of water. You just water your plants with the solution every two to four weeks, and you'll see steady growth and richer green leaves. The liquid is concentrated enough that a single bottle lasts months for a typical indoor collection. Mixing is straightforward, though you'll need your own quart container or measuring cup.

In terms of performance, this fertilizer delivers balanced nutrients that support both foliage and root development. Many users report noticing new leaves and stronger stems within two to three weeks of starting regular feeding. It works especially well for leafy tropical plants like monstera and fiddle leaf fig, which benefit from the steady nitrogen boost. For flowering indoor plants, you might want a bloom-specific formula, but for general health and green growth, this is a great everyday option.

Build quality is typical for a plastic bottle with a child-resistant cap, and the label clearly lists all ingredients. One minor drawback is the lack of a measuring cup, but the cap itself serves as a measure (half cap per quart). Also, because it's an organic concentrate, it's best used within a year of purchase; opened bottles should be stored in a cool, dark place to maintain potency.

Overall, Espoma Organic Indoor Plant Food is a reliable, affordable, and pet-safe way to keep your houseplants thriving. If you value organic ingredients and want a no-fuss feeding routine, this is one of the best values you'll find under ten dollars. It won't replace specialized bloom boosters or heavy-duty outdoor fertilizers, but for everyday indoor plant care, it does exactly what it promises.

Organic Plant Magic is a water-soluble, all-purpose plant food designed to feed a wide variety of plants quickly and naturally. It’s aimed at home gardeners, vegetable growers, and indoor plant enthusiasts who want an organic alternative to synthetic fertilizers. The product comes as a fine powder that you mix with water, making it easy to apply during your regular watering routine.

The standout feature here is speed. Users report greener leaves and more vigorous growth within 1-2 days of application. That fast action comes from a complete nutrient package that includes nitrogen, phosphorus, potassium, plus over 55 trace minerals, kelp, amino acids, humic acids, and beneficial GroBiotics (mycorrhizae). These ingredients not only feed the plant directly but also improve soil biology for long-term health. The concentrate is powerful: a half-pound bag creates more than 32 gallons of liquid feed or covers 1,000 square feet of garden space.

The powder form is practical but has a couple of trade-offs. On the plus side, it dissolves quickly in water and can be used for soil drenching, foliar feeding, or root soaking. On the downside, the fine powder can create dust if you’re not careful when scooping or mixing. There’s also no slow-release mechanism, so you’ll need to reapply every week or two during active growth. For most gardeners, that’s a minor inconvenience given the visible results.

One potential drawback for some buyers is the price point. At around $27 for a half-pound bag, it costs more per application than some synthetic concentrates. However, the organic ingredients and the fact that a little goes a long way help offset the upfront cost. It’s also worth noting that the manufacturer claims the product is safe for kids, pets, and the planet, which adds peace of mind for families.

Overall, Organic Plant Magic is a solid choice for anyone looking for a fast, organic feed that works on almost any plant. It’s especially good for vegetable gardens and houseplants where you want quick results without synthetic chemicals. The powder can be a bit messy and requires regular mixing, but the benefits of healthier plants and improved soil biology make it a worthwhile addition to your gardening toolkit.

Espoma Organic Bloom! is a concentrated liquid plant food designed specifically to boost flowering in a wide range of plants. Whether you're tending to annuals, perennials, or hanging baskets, this organic fertilizer helps promote vigorous growth and more abundant blooms. It's an excellent choice for gardeners who want to avoid synthetic chemicals and prefer a natural approach.

The formula features a balanced 1-3-1 NPK ratio, which is low in nitrogen but higher in phosphorus to support flower development. It also includes natural proteins, kelp extracts, and humic acids that improve soil health and nutrient uptake. Users simply mix the concentrate with water as directed and apply every two to four weeks during the growing season. This makes it easy to integrate into a regular watering routine.

Espoma has been a leader in organic gardening since 1929, and Bloom! lives up to that reputation. It's approved for organic gardening and contains no sludges or toxic ingredients. The liquid concentrate is straightforward to use, though it does require mixing before each application. The 16-ounce bottle is compact and can treat a fair number of plants, but gardeners with extensive beds might need multiple bottles.

One potential drawback is that it's not a ready-to-use spray, so you'll need a watering can or sprayer. Additionally, while the organic ingredients are gentle, they may work more slowly than synthetic bloom boosters. However, for those committed to organic practices, this is a minor trade-off.

Overall, Espoma Organic Bloom! is a reliable, effective bloom booster for organic gardeners. It delivers on its promise to encourage flowering without harsh chemicals. If you want an easy-to-mix liquid fertilizer that supports both plant health and the environment, this is a solid choice.

Espoma Plant-Tone is a classic organic fertilizer that has been a go-to for gardeners for generations. This 50 lb. bag provides a generous supply of slow-release nutrients for almost everything you might grow, from flowers and vegetables to trees and shrubs. With an N-P-K of 5-3-3 and added calcium, it's designed to support healthy growth and strong cell structure, which is especially helpful for preventing issues like blossom end rot in tomatoes.

What sets Plant-Tone apart is its simplicity and reliability. The granules are ready to use right out of the bag, so there's no mixing or measuring liquids. Just sprinkle it around the base of your plants and water it in. Many users report noticeable improvements in plant color and vigor within a few weeks. The Bio-tone formula adds beneficial microbes to the soil, which can further boost nutrient availability over time. For gardeners who prefer organic methods, it's approved for organic production, giving you peace of mind.

One thing to be aware of is the smell. Several reviewers mention that Plant-Tone has a strong, earthy odor that can be off-putting. It's not a chemical smell, but it is potent, especially when the bag is first opened. Wearing gloves and gardening clothes is a good idea, and the scent fades after it's watered in. Also, while it's a fantastic all-purpose base, some experienced gardeners like to supplement with extra potassium for root crops or a nitrogen boost for leafy greens. It's not a drawback per se, but something to keep in mind if you have very specific crop needs.

Overall, Espoma Plant-Tone delivers consistent results at a great price point. The 50 lb. bag offers considerable coverage for the cost, making it a smart choice for anyone with a large garden or multiple planting areas. The slow-release nature means fewer applications, and the organic ingredients support a healthy soil ecosystem. If you are looking for a dependable, straightforward organic fertilizer that works across the board, this is a solid investment.

Burpee's Natural Purpose Organic Granular Plant Food is a straightforward, all-purpose fertilizer designed for gardeners who want to feed a variety of plants without fuss. This 4-pound bag is packed with organic nutrients plus beneficial microbes, and it's OMRI listed, meaning it meets organic gardening standards. Whether you're starting seeds, tending a vegetable patch, or maintaining container flowers, this product aims to simplify your feeding routine while keeping soil healthy.

The standout feature is its extended release: nutrients are released immediately and continue feeding for up to 3 months. That's a big plus for busy gardeners who don't want to reapply every few weeks. The formula includes calcium and micronutrients, which support strong growth and better blooms. In practice, you sprinkle the granules around plants and water them in. The process is clean and quick, though you do need to make sure the granules are moist to activate. No mixing required, which saves time.

Build quality is typical for a granular fertilizer: the bag is sturdy and easy to reseal if you don't use the whole amount at once. Burpee is a well-known brand with over a century of gardening expertise, so you're getting a product backed by experience. The granules themselves are uniform and not overly dusty, making application pleasant. Directions on the bag are clear, with recommended amounts for different plant types. That's helpful for beginners who might be unsure how much to use.

On the downside, the lack of a specific NPK ratio might bother gardeners who like to tailor fertilizer to particular crops. The product description mentions major nutrients but without numbers, you're trusting the brand's general-purpose blend. Also, since the product has no customer reviews yet, it's hard to gauge how it performs in diverse soils and climates. The price point is moderate compared to synthetic alternatives, but for an organic fertilizer with long-lasting effects, it's reasonable.

Overall, Burpee's Organic All-Purpose Plant Food is a solid choice if you want a reliable, no-nonsense granular fertilizer for mixed gardens. It's especially good for container growers and vegetable gardeners who value organic certification and slow-release feeding. Just remember to water it in and expect to see results over the season. For the price and trusted brand name, it's worth a try.

GrowQueen Organic Liquid Indoor Plant Food is a concentrated 5-5-5 fertilizer designed for houseplants, tropicals, and all-purpose indoor use. It stands out as one of the few true organic liquid fertilizers that deliver professional-grade nutrition without the risk of burning delicate roots. Whether you're a beginner or an experienced plant parent, this formula makes feeding simple and effective.

The standout feature is its instant-acting nature. Mix one serving per gallon of water and apply directly to the soil. Users report visible improvements in leaf color and growth within days. The inclusion of cold-processed Ecklonia maxima sea kelp provides natural auxins and trace minerals that promote explosive root expansion and thicker stems. Unlike some synthetic fertilizers, this one also nourishes beneficial soil microbes, improving soil structure and nutrient uptake over time.

In terms of design, the 8 oz bottle is compact and easy to store. The liquid is odor-free, which is a huge plus for indoor use. The formula is gentle enough for weekly feeding yet potent enough to support heavy feeders. It pairs well with GrowQueen's other soil products for a complete care system. The only minor drawback is that it requires mixing each time, and for very large collections, the bottle may need to be replaced more often. But considering it treats up to 50 gallons, it offers good value.

Overall, GrowQueen Organic Liquid Plant Food delivers on its promises. It's a reliable, eco-friendly option for anyone looking to boost their indoor plants' health without harsh chemicals. The balanced NPK and micronutrients make it a versatile choice for everything from ferns to flowering houseplants. If you want a simple, effective organic fertilizer that shows results fast, this is a solid pick.

If you're looking for an organic fertilizer that actually delivers results without a lot of fuss, Miracle-Gro Organic Plant Food is worth a close look. This liquid plant food is made from 94% plant-based ingredients and is OMRI listed, meaning it meets organic gardening standards. It's designed for all types of plants, from indoor houseplants like pothos and coleus to outdoor vegetables, herbs, and flowers. Whether you're a seasoned gardener or just starting out, this is a straightforward way to give your plants a healthy boost.

What sets this fertilizer apart is how quickly it works. Users consistently report seeing greener leaves, stronger stems, and more vibrant blooms within a week or two of use. The liquid formula mixes easily with water, and you can apply it by simply soaking the soil around each plant. For outdoor gardens, you mix 2 capfuls per gallon of water and feed every 7 to 14 days. For indoor plants, just 1 capful per gallon every two weeks does the trick. One 32-ounce bottle makes up to 10.75 gallons of diluted fertilizer, which is enough to feed about 10 medium-sized plants for a full growing season.

In terms of design and build quality, the product is straightforward. The bottle is sturdy and easy to grip, and the cap doubles as a measuring cup with clear fill lines. The liquid itself is thick and dark, so you'll want to shake it well before each use. Some users mention a mild fish-like smell, which is common with organic fertilizers, but it's not overwhelming and dissipates quickly after watering. The lack of harsh chemical odors is a big plus for indoor use.

No product is perfect, and there are a couple of things to keep in mind. Because it's a liquid concentrate, larger gardens may go through the bottle faster than expected. Also, the thickness can make it a bit tricky to pour without spilling, so go slow. But these are minor trade-offs for an effective, organic formula that's gentle on plants and the planet.

Overall, Miracle-Gro Organic Plant Food earns high marks for its ease of use, fast results, and organic certification. With a 4.6-star average from over 250 reviews, it's a reliable choice for anyone who wants to feed their plants naturally. If you're tired of fertilizers that promise a lot but deliver little, this one actually delivers.

The Down To Earth Organic Citrus Mix 6-3-3 is a targeted fertilizer for anyone growing citrus trees or avocados. Whether you have a single potted key lime on a patio or a small orchard, this blend is designed to support healthy foliage, strong flowering, and better fruit production. It's a favorite among organic gardeners because it skips synthetic chemicals and uses natural ingredients instead.

The formula delivers a balanced 6-3-3 NPK ratio plus calcium, sulfur, iron, and zinc. These aren't just marketing words. Real users have shared before-and-after photos showing dramatic growth, more blossoms, and juicier fruit. One reviewer said their key lime tree went from "meh" to "whoa" after using this mix. Another noted their lemon tree looked alive again after just a few applications. The granular form is easy to work with: you simply spread it around the drip line or mix it into the soil, then water it in.

What sets this product apart is its organic certification and ingredient list. It includes feather meal, fish bone meal, alfalfa meal, langbeinite, basalt, kelp, and humic acids. These components feed the soil as well as the plant, which is great for long-term garden health. The 1 lb box is handy for small-scale use, but keep in mind that coverage is modest. You might need multiple boxes for larger trees or more frequent feeding.

The biggest downside is the smell. Several reviewers mentioned it has a strong, manure-like odor that lingers. It's fine for outdoor use, but definitely not something you want to bring indoors. A few customers also reported that the box arrived damaged, though the product itself was fine. And while the instructions say to apply 3-4 times a year, some heavy feeders may need more frequent applications to see the best results.

Overall, the Down To Earth Organic Citrus Mix is a solid choice for organic citrus care. It's effective, easy to use, and backed by plenty of positive feedback from real growers. If you can handle the smell and don't mind buying larger quantities for bigger trees, this fertilizer is worth adding to your garden routine.

Brut Organic Worm Castings are a premium, OMRI-certified soil amendment that harnesses the power of earthworms to deliver concentrated nutrients. This 5-pound bag is designed for both indoor and outdoor plants, from seedlings to vegetable gardens. If you're looking for a natural way to enrich your soil without harsh chemicals, this product is a solid choice.

The standout feature is the high density of NPK and trace minerals, combined with a thriving population of beneficial microbes. Unlike synthetic fertilizers that can burn roots, these castings release nutrients slowly, improving soil structure over time. In real-world use, plants showed greener leaves and more vigorous growth, especially when mixed into potting soil or used as a top dressing for garden beds.

Production quality is excellent. The castings are raised indoors in containers, ensuring consistency and purity. The granules are fine and easy to work with, and they have virtually no odor. The bag is resealable, which helps maintain freshness. As a family-owned brand, Brut Worm Farms emphasizes quality control, and the OMRI and CDFA certifications back that up.

One downside is the price. At around $13.49 for 5 pounds, it's more expensive than basic compost or synthetic options. Also, because it's slow-release, heavy feeders like tomatoes or corn may need additional fertilizer during peak growth. But for most gardeners, the convenience and safety of organic castings outweigh these minor drawbacks.

Overall, Brut Organic Worm Castings are a reliable, eco-friendly soil builder that delivers real results. They're ideal for organic gardeners, indoor plant enthusiasts, and anyone wanting to improve soil health naturally. If you're willing to invest in quality, this product won't disappoint.

SmartGrower Organic Plant Food is a concentrated powder fertilizer designed for anyone who wants to grow healthier plants without harsh chemicals. It's ideal for vegetable gardeners, indoor plant enthusiasts, and flower lovers looking for an organic, vegan option that actually delivers. The product blends essential nutrients with five strains of beneficial bacteria (Bacillus velezensis, subtilis, altitudinis, pumilus, licheniformis, and megaterium) to create a living soil amendment that supports root growth and nutrient uptake.

The standout feature here is the inclusion of live microbes alongside humic acid (3.85%) and fulvic acid (4.65%). These microorganisms work synergistically to improve soil structure and help plants absorb calcium, magnesium, and other vital elements more efficiently. With 1% nitrogen, 2% potassium, and a balanced phosphorus level, this fertilizer targets lush foliage and abundant harvests without the risk of burning plants that comes with synthetic alternatives.

In terms of usability, SmartGrower comes as a water-soluble powder in a 125g pouch. The included scoop makes measuring simple, and the mixing ratio of 1:1024 means one packet treats up to 30 gallons of water. It's designed for both indoor potted plants and outdoor vegetable gardens, so you can use a single product for all your gardening needs. The powder dissolves relatively quickly, though you will want to stir thoroughly to avoid sediment.

One honest drawback is that this is a new product with zero customer reviews, so you are relying entirely on the brand's claims and ingredient list. Also, while the microbial count is impressive, results can vary based on your soil's existing biology and growing conditions. Some gardeners may need to experiment with frequency to see optimal benefits for specific plants. The price point is not listed here, but concentrated formulas often offer good value if you have a large garden.

Overall, SmartGrower Organic Plant Food is a promising option for gardeners committed to organic methods. Its combination of beneficial bacteria and balanced nutrients addresses both plant and soil health. If you are comfortable trying a newer brand with a transparent ingredient list, this powder could be a solid addition to your gardening routine. Just be prepared to adjust your watering and application schedule as you learn how your plants respond.

Neptune's Harvest Fish & Seaweed Liquid Fertilizer is an organic, all-purpose plant food that combines 75% hydrolyzed fish with 25% seaweed. This 2-3-1 NPK formula delivers a balanced nutrient profile that supports everything from vegetable gardens to indoor houseplants. It's designed for gardeners who want a natural, effective liquid fertilizer that's safe for kids and pets.

The standout feature is its dual action: it feeds plants directly while also improving soil health. The hydrolyzed fish and seaweed provide nutrients in a form plants can use immediately, and the organic matter feeds beneficial soil microbes. Over time, this leads to looser soil that retains moisture better and drains well. You can apply it as a soil drench or foliar feed, and the mixing instructions are straightforward - 1 oz per gallon for outdoor plants, 1 tablespoon per gallon for indoor plants.

In real-world use, this fertilizer consistently produces greener leaves, stronger stems, and more vibrant flowers. Gardeners report better-tasting vegetables and brighter blooms. It's especially effective on transplants, helping them establish quickly with less shock. The soil-building benefits become noticeable after a few applications, with improved texture and root growth.

There are a couple of drawbacks to consider. The fishy smell is strong right after application, though it fades within a day or two. Also, because it's a liquid, you need to reapply every 1-2 weeks for outdoor plants, which is more frequent than granular slow-release options. The 36 oz bottle is convenient for small to medium gardens, but larger plots may require buying multiple bottles.

Overall, Neptune's Harvest Fish & Seaweed Liquid Fertilizer is a top-tier organic choice for any gardener who values natural ingredients and visible results. It's easy to use, versatile, and backed by a stellar reputation. If you're committed to organic gardening and don't mind the occasional odor, this fertilizer delivers everything you need for healthy, productive plants.
