Tomatoes and strawberries are two of the most popular fruits to grow in home gardens Their sweet, juicy flavors when picked fresh cannot be matched by store-bought varieties It’s no wonder many gardeners try to maximize their limited space by planting tomatoes and strawberries together. But is this a good companion pairing? Or are these fruits better grown separately?
The Short Answer
The short answer is no, you shouldn’t plant strawberries and tomatoes together. It is possible for fungal diseases like verticillium wilt and anthracnose to spread from one plant to another that is close by. You should put strawberries and tomatoes in different parts of your garden.
The Long Answer
While tomatoes and strawberries are botanically very different plants they share some problematic disease susceptibilities that make them poor companions. Let’s look at why it’s best not to plant tomatoes and strawberries together.
Disease Susceptibility
Tomatoes and strawberries should not be grown together because they can both get diseases from fungi that grow in the soil. The two most concerning diseases are verticillium wilt and anthracnose. These fungal pathogens can quickly move from a plant that is sick to plants that are healthy nearby.
Both tomatoes and strawberries are prone to verticillium wilt, which is caused by the fungus Verticillium dahliae. This fungus causes leaves to yellow, wilt, and die. It also causes shriveling and rotting of fruits.
Anthracnose is another fungal disease caused by the fungus Colletotrichum acutatum. It results in dark, sunken lesions on fruits, sometimes rotting them entirely. Leaves develop necrotic brown spots that spread rapidly.
If tomatoes and strawberries are planted near each other and one becomes infected, the disease can easily spread to the other via water, garden tools, and insect activity. Planting them separately reduces transmission risk.
Other Drawbacks
In addition to being more likely to get diseases, tomatoes and strawberries have different needs and ways of growing that make them bad companions:
-
Strawberries are a cool-weather perennial, while tomatoes are an annual that grows in warm weather. Their seasons of active growth don’t overlap well.
-
Tomatoes need tall trellising or cages, which could shade out low-growing strawberry plants.
-
Strawberries spread aggressively via runners, which could overtake tomato root space.
-
Tomato fertilizer needs differ from strawberries, making it hard to fertilize both crops optimally.
Better Companion Options
Rather than planting tomatoes and strawberries together, both plants have better companion options that can be planted nearby.
Good tomato companion plants include:
- Basil
- Carrots
- Onions/chives/garlic
- Marigolds
- Nasturtiums
- Borage
Great companion plants for strawberries include:
- Bush beans
- Lettuce/spinach
- Borage
- Thyme
- Sage
- Marigolds
These plants help repel pests, improve pollination, or enhance flavor. Avoid planting strawberries near nightshades like tomatoes, peppers, or eggplants to limit fungal disease spread.
Growing Tips for Tomatoes and Strawberries
If you want to grow both tomatoes and strawberries, just don’t plant them right next to each other. Here are some tips for growing each successfully:
Tomatoes
- Grow in full sun (at least 8 hours/day)
- Enrich soil with compost and fertilizer
- Water 1-2 inches per week
- Use cages or trellises for support
- Prune suckers and lower leaves
- Harvest ripe fruits promptly
Strawberries
- Grow in full sun (at least 10 hours/day)
- Enrich soil with compost
- Water 1 inch per week
- Use raised beds or containers
- Refresh plants every 2-3 years
- Harvest ripe berries often
With the right care and companions, you can grow bountiful, delicious tomatoes and strawberries—just keep these fruits in separate garden beds. Pay close attention for any disease symptoms and remove affected plants promptly. With smart garden planning, you can avoid problems and enjoy the sweet flavor of homegrown tomatoes and strawberries.
Plants to Avoid in your Strawberry Patch
There are some plants that shouldn’t be planted next to each other, and if you do, they could kill your strawberries. In this case, strawberry plants are prone to a disease called verticillium. Strawberry plants may get this deadly disease from plants like peppers, roses, mint, okra, tomatoes, eggplant, potatoes, melons, and melons. It’s important to remember that you shouldn’t even plant strawberries in beds that have recently been used for the plants on this list.
Strawberries are also not the best companions for plants that are in the cabbage family. Not only aren’t they good neighbors, but they are destructive neighbors, as they hamper the growth of cabbage family members. Common cabbage groupings include collard greens, kale cauliflower, kohlrabi, bok choy, and brussel sprouts.
Best Strawberry Companion Plants
Here is a robust list of plants that will offer some pest protection for your strawberry plants and help you grow a hardy bumper crop of strawberries. Plant these garden friends alongside strawberry plants and enjoy the extraordinary benefits of companion planting.
Asparagus and strawberries are natural interplanting partners in the garden bed. They spread their roots on alternate planes of the soil, and they both emerge from the ground soon after the last frost. These two garden mates use the soil effectively without competing with one another and contributes to nutrient return.
Borage is an herb that works double duty for strawberries in the garden bed. Not only does borage repel damaging insects, but it also attracts beneficial insects and pollinators to the strawberry patch.
Caraway attracts insects that feed on pests that can cause significant damage to strawberries. Such insects included parasitic flies and wasps that will protect strawberries from fruit seeking pests like aphids and mites.
Catnip deters damaging insects such as aphids and mites from destroying the leaves of strawberry plants. Strawberry plants are particularly prone to attracting both of these garden pests.
Yarrow attracts beneficial pollinators to your garden, which can boost the yield of your strawberries.
These pungent vegetables make great strawberry companion plants. Their unappealing odor is a natural deterrent of many garden pests that feed on the leaves and fruits of the strawberry plant.
Sage is another one of those herbs that emit a strong odor and has also been successful in masking the sweet scent of your strawberries in the garden, making it more difficult for destructive pests to find your berries plants.
Not only do spinach and strawberries make an excellent combination in the salad bowl, but they are also super compatible in the garden. Spinach contains saponins, which act as a natural repellent of destructive garden pests.
