The 8 Best Companion Plant for Tomatoes of 2026

The Bonnie Plants Early Girl Tomato 4-pack delivers live starter plants for gardeners who want the first slicing tomatoes of the season. With a 50-day maturity, these indeterminate vines produce a steady crop of red, sweet fruit perfect for salads, sandwiches, or fresh eating. They are especially suited to growers in zones 3-10 who want a reliable, early harvest.

The key selling point is the head start these plants provide. Instead of starting from seed, you get young plants already weeks old, which speeds up the growing process. Many reviewers report receiving healthy, robust plants that established quickly and began producing within the expected timeframe. However, a few customers experienced plants that arrived stressed or leggy, likely due to shipping conditions. The disease resistance to verticillium and fusarium wilt is a genuine benefit, especially for gardeners in areas where these soil-borne diseases are common.

As live plants, packaging matters. Bonnie Plants ships in sturdy containers with moist soil, and most deliveries arrive in good shape. Each plant is typically 6-10 inches tall with developed root systems. The variety is indeterminate, meaning it will grow tall and require staking or caging for support. Full sun and regular watering are essential for best yields.

The main drawbacks are related to shipping variability. Some plants may arrive with yellow leaves or breakage, and a minority of buyers have had plants die within the first two weeks. Additionally, as an indeterminate variety, these tomatoes need consistent support and care. They are not space savers, so plan for enough room in your garden.

Overall, the Bonnie Plants Early Girl Tomato 4-pack is a solid choice for gardeners who want to jump straight into the season. Its early maturity, disease resistance, and productive vines outweigh the occasional shipping issues. If you are ready to provide support and consistent care, these plants will reward you with a delicious early harvest.

The Bonnie Plants Super Sweet 100 Cherry Tomato is a live plant pack that brings the joy of homegrown tomatoes to your garden with minimal effort. This 4-pack of organic starter plants is perfect for gardeners who want a reliable, high-yield variety that tastes amazing right off the vine. Whether you are a seasoned grower or just starting out, these vigorous indeterminate vines are designed to produce sweet, bite-sized fruit all season long.

What makes Super Sweet 100 stand out is its exceptional flavor and disease resistance. The tomatoes are packed with sugar and vitamin C, offering a burst of sweetness that rarely makes it to the salad bowl (you will eat them straight from the plant). This hybrid has been improved to resist verticillium wilt and fusarium wilt, two common soil-borne problems that can ruin a crop. That means less worry and more tomatoes, even if your garden soil has issues.

These plants grow like crazy, reaching up to 12 feet tall if given vertical support. The indeterminate vines keep producing new clusters of fruit until the first frost, so you get a continuous harvest rather than one big flush. Plan on using a tall stake, cage, or trellis from the start - these plants will climb over the top and keep going. They need full sun and consistent moisture to thrive, and well-drained, nutrient-rich soil with a pH between 6.2 and 6.8 is ideal.

One thing to keep in mind: the vigorous growth and high yield demand regular watering and feeding. Skipping water can lead to cracked fruits or blossom end rot, so mulching and a consistent schedule help. Also, while disease resistant, they are not immune to all issues, and the long season means you may need to manage pests late in summer.

Overall, the Bonnie Plants Super Sweet 100 Cherry Tomato is a fantastic choice for anyone who loves sweet, snackable tomatoes and wants a productive, low-maintenance addition to a sunny garden. With strong disease protection, high yields, and incredible flavor, it delivers on its name and then some. Just give them room to climb and keep the water coming.

The Bonnie Plants Patio Tomato 4-Pack is a fantastic option for anyone who wants to grow fresh tomatoes but lacks garden space. These live plants are compact, reaching only about 2 feet tall, and are specifically bred for containers and small gardens. They are determinate, meaning they produce all their fruit in a concentrated period, which is great for preserving or enjoying a steady harvest. The plants come with built-in disease resistance to fusarium wilt, Alternaria stem canker, and gray leaf spot, so you spend less time worrying about common tomato ailments.

Real-world performance is impressive. Multiple buyers report that the plants arrived healthy and well-packaged, with many noting they produced fruit all summer long. The tomatoes are described as having great flavor and a nice shape, ideal for salads, fresh eating, or even shish-kebabs. With a maturity of 70 days after planting, you won't wait long to enjoy the fruits of your labor. The compact size also means you can easily move pots to catch the best sunlight, though the product listing incorrectly lists 'Full Shade' as a sunlight requirement; tomatoes actually need full sun for best results.

Design and build quality are solid. Bonnie Plants has over 70 greenhouses across the country, so your plants don't travel far, reducing stress. They arrive in a mini greenhouse-like packaging that keeps soil moist and plants protected. Each plant is 19.3 oz and comes as a 4-pack, giving you a head start on the season. The only real downside is shipping sensitivity: if left outside in freezing temperatures, the plants can suffer damage or die, as a few reviews mentioned. Ordering during mild weather or ensuring someone is home to receive the package can mitigate this.

Another consideration is price. These are a bit more expensive than buying from a local nursery, but the convenience of home delivery and the ability to get specific varieties makes it worthwhile for many. Also, the plants benefit from a small cage or stake for support, so plan accordingly. Overall, the Bonnie Plants Patio Tomato 4-Pack is a reliable choice for container gardeners, beginners, or anyone with limited space who wants a productive, low-maintenance tomato plant.

Verdict: If you're looking for a hassle-free way to grow delicious tomatoes on a patio, balcony, or small garden, this 4-pack delivers. The disease resistance and compact growth make it a standout, and the positive reviews confirm its performance. Just be mindful of shipping weather and provide full sun for best results.

The Bonnie Plants Roma Tomato Plugs 6-Pack is designed for gardeners who want a convenient head start on growing paste tomatoes. These live young plants are meant for transplanting into raised beds or in-ground gardens after the danger of frost passes. They are a great option for anyone who loves making homemade tomato sauce, paste, or canned goods, as the determinate Roma variety produces a heavy crop over a short window.

In terms of real-world performance, feedback is mixed. Many users report that the plugs arrived healthy and grew into productive plants, yielding plenty of Roma tomatoes for fresh eating and preserving. The determinate nature makes them easy to manage, especially with staking or caging for support. However, a significant number of customers have reported issues: some plants arrived dead or diseased, and others failed to produce fruit despite healthy foliage. This inconsistency is a concern, especially for a product that relies on live shipping.

The build quality of the plants themselves is typical for live plugs. They come in a compact 3 cubic inch size and are packaged to survive transit. When they arrive in good condition, they establish quickly and grow vigorously in full sun and well-draining soil. The 70 to 80 day maturity is on par for Roma tomatoes, and with proper care, the plants can reach 48 to 60 inches tall. Bonnie Plants' reputation suggests these should be reliable, but the reviews indicate quality control may vary by batch.

Drawbacks are worth noting. The most common complaints involve dead or weak plants on arrival, which defeats the purpose of buying live plants. Some users also experienced plants that grew well but never flowered or set fruit. This could be due to environmental factors, but the frequency of such reports suggests potential issues with the plant stock itself. Additionally, the plugs are quite small and require careful handling to avoid transplant shock.

Overall, the Bonnie Plants Roma Tomato Plugs are a convenient option for gardeners who want to skip seed starting, but they come with some risk. If you get a healthy batch, you'll enjoy a bountiful harvest perfect for sauces and preserving. However, be prepared for the possibility of disappointing results and consider ordering early to allow time for replacements. With proper care and a bit of luck, these plugs can be a great addition to your garden.

The Bonnie Plants Black Cherry Tomato 4-Pack is a great shortcut for anyone who wants a bountiful harvest without the fuss of starting seeds. These live plants are ready to go straight into your garden or container, making them ideal for both new and experienced gardeners. The indeterminate vines grow 4 to 6 feet tall and start producing fruit in about 64 days, then keep going until the first frost.

The deep-purple, one-inch tomatoes are the star here. They have a sweet, complex flavor that stands out in salads, salsas, tarts, and even on charcuterie boards. Plus, they're rich in antioxidants, so you can feel good about snacking on them fresh off the vine. Many customers report heavy yields, with some saying the plants produced more than they could use. The plants are open-pollinated, so you can save seeds if you like, though the hybrid vigor is lost.

When it comes to growing, these tomatoes are easy to handle if you give them full sun and plenty of water. A cage or stake is a must because the vines get heavy with fruit. Bonnie recommends spacing them 36 inches apart and using a balanced fertilizer like Miracle-Gro. In terms of build quality, the plants arrive in a compact box, well-packaged but sometimes stressed from shipping. Most reviewers said they bounced back quickly after planting and watering.

There are some drawbacks worth noting. A few customers received plants that were wilted or died shortly after arrival, which could be due to shipping delays or temperature extremes. One reviewer also mentioned that the box didn't label the tomato variety, which might confuse someone who ordered multiple types. Bonnie seems responsive to issues though; a few customers reported getting replacement plants quickly after complaining.

Overall, the Bonnie Plants Black Cherry Tomato 4-Pack delivers on its promise of a prolific, tasty harvest with minimal upfront work. For about $18, you get four strong starter plants that can easily yield dozens of fruit each. If you're looking for a reliable cherry tomato that's both beautiful and delicious, this is a solid choice. Just be prepared to give them support and water, and you'll be enjoying sweet, homegrown tomatoes all summer long.

The Bonnie Plants Park's Whopper Improved Tomato is a standout choice for home gardeners who want a productive, disease-resistant indeterminate tomato without the wait of starting from seed. This 4-pack of live plants arrives ready to transplant, giving you a head start on a long season of meaty, slicing tomatoes. Whether you're a seasoned gardener or a beginner looking for a reliable variety, these plants are designed to deliver abundant harvests with minimal fuss.

What sets Park's Whopper Improved apart is its enhanced disease resistance. It's bred to withstand fusarium wilt (races 1 and 2), verticillium wilt, nematodes, and tobacco mosaic virus. That means less worry about soil-borne diseases common in many garden beds. In real-world use, customers report healthy, vigorous growth with vines reaching 8 to 10 feet tall and producing 60 to 80 pounds of fruit per plant. The 65-day maturity is notably quick for an indeterminate type, so you can start picking bright red tomatoes earlier and keep harvesting until the first frost. The fruits are meaty and flavorful, ideal for slicing onto sandwiches, dicing into salads, or cooking into sauces.

Design and build quality are straightforward: these are live plants shipped in protective packaging. Most buyers praise the robust health of the plants upon arrival, though a few mention occasional dry or stressed specimens, which can happen with shipping. Once planted in full sun with moderate watering and a sturdy cage or stake, these tomatoes thrive. The indeterminate growth habit means they'll need plenty of vertical support and space, but the payoff is a continuous supply of tomatoes. Bonnie Plants backs their varieties with years of breeding expertise, so you can trust the genetics.

On the downside, these plants are not for those seeking a compact tomato. They require consistent staking and will sprawl if not trellised. Additionally, while packaging is usually excellent, extreme weather during shipping can sometimes affect plant health. But overall, the Park's Whopper Improved Tomato is a smart investment for gardeners who value high yields, disease resistance, and early harvests. With proper care, you'll be rewarded with a summer-long bounty of delicious, homegrown tomatoes.

The Bonnie Plants Red Beefsteak Tomato 4-pack is a live starter plant set aimed at home gardeners who want the classic, meaty flavor of an heirloom beefsteak without the wait of growing from seed. This variety is a popular choice in the Northeast and across the U.S., prized for its large, dense fruit that's ideal for slicing onto sandwiches and burgers. If you're a gardener who values taste over early harvest, this late-maturing plant might be your ticket to a fresh, homegrown tomato supply well into fall.

The real standout here is the disease resistance. Fusarium wilt and nematodes are common tomato killers, but these plants are bred to fight them off, giving you a leg up. They're indeterminate, meaning they'll keep climbing and producing until frost, so a tall cage or stake is a must. The 90-day maturity is on the longer side, but that's exactly what you want if your summers are hot and you'd rather have tomatoes in September than in July. Reviews show that most plants arrive in great shape, packed in individual plastic containers that keep them safe. Several buyers rave about how healthy and vigorous the seedlings are, even before transplanting.

On the flip side, a handful of customers reported that all their plants died within a week, despite using premium soil and care. Others noted that the plants arrived with broken stems or wilted leaves. This suggests that shipping can be rough, and while Bonnie Plants packs them well, there's some inconsistency. Also, the late harvest is a double-edged sword: if your first frost comes early, you may not get many ripe fruits. One reviewer mentioned that even by mid-September, the tomatoes were still green and small, though what did ripen was delicious. So patience is required, and you'll need to factor in your local climate.

Build quality of the plants themselves is generally high. They're young but sturdy, with strong root systems that transplant well when handled correctly. The packaging is definitely a plus over cheaper competitors that just wrap plants in paper. Still, the risk of losing a plant to transport damage is real, and the price point is a bit higher than seeds or bargain nursery starts. If you're okay with that trade-off, the payoff is a steady supply of hefty, flavorful tomatoes that'll make your summer salads shine.

Final verdict: The Bonnie Plants Red Beefsteak Tomato 4-pack is a solid investment for gardeners who prioritize taste and disease resistance and can handle the long wait for harvest. It's less ideal for beginners or those in short-season climates, but for the experienced grower looking for a late-summer treat, it's well worth trying. Just be prepared to pamper the plants a bit after arrival to maximize your odds.

Carrots Love Tomatoes is the 50th anniversary edition of a classic companion planting guide by Louise Riotte. This book is for anyone who wants to grow a healthier, more productive garden by harnessing natural plant relationships. Whether you're a beginner or a seasoned organic gardener, the advice here helps you pair vegetables, herbs, and flowers to boost growth, deter pests, and improve soil fertility without relying on chemicals.

The standout feature is the extensive list of plant partnerships and antagonisms. You'll learn that planting parsley near asparagus increases yields, while broccoli and tomatoes should stay far apart. The book also covers how leeks and carrots protect each other from carrot and onion flies, and how weeds like dandelion and comfrey can be used as nutrient-rich mulch or compost. These practical tips are supported by sample garden plans and a cautionary guide to avoid harmful combinations.

At 224 pages, the paperback is compact and easy to take into the garden. The writing is straightforward and conversational, making complex concepts accessible. The second edition includes a foreword by renowned gardener Charles Dowding, which adds modern credibility to the timeless wisdom. The binding feels sturdy enough for repeated use, though the black-and-white illustrations are functional rather than flashy.

One drawback is that this specific edition has no customer reviews yet, so you won't find recent user feedback before buying. Also, gardeners looking for flashy photos or cutting-edge research may find the presentation a bit old-school. However, the core advice has been validated by generations of growers and remains highly relevant for anyone committed to organic methods.

Overall, Carrots Love Tomatoes delivers exactly what it promises: clear, actionable companion planting strategies that can transform your garden. At under $10, it's an exceptional value for the depth of knowledge it provides. I highly recommend it to anyone wanting to grow a balanced, pest-resistant garden without synthetic inputs.
