Yes, strawberries and tomatoes grow well as companion plants

Strawberries and tomatoes can share the same garden bed and actually benefit from each other's presence. Strawberries grow low to the ground and spread horizontally, while tomatoes grow tall and vertical, so they use different layers of space without competing for light. Strawberries also help suppress weeds around tomato plants, and their shallow root systems don't interfere with tomato roots that dig deeper into the soil.

The main reason gardeners pair these two is practical: you can harvest two crops from roughly the same footprint. Strawberries produce fruit in spring and early summer, then tomatoes take over with their peak harvest in mid to late summer. This succession means you're using the garden's resources across a longer season rather than having one bed sit idle while waiting for the next crop.

Key Takeaways

  • Plant strawberries at ground level and tomatoes 18 to 24 inches away so the tomato's root system doesn't shade or crowd the strawberry plants.
  • Strawberries prefer slightly acidic soil (pH 6.0 to 6.8), while tomatoes tolerate a wider range, so test your soil before planting and amend if needed.
  • Water strawberries at soil level to keep leaves dry and prevent fungal disease, and water tomatoes deeply but less frequently to encourage deep roots.
  • Harvest strawberries in late spring, then remove the spent plants before tomatoes reach full size to prevent shading and disease spread.

Spacing and placement to prevent crowding

Give each strawberry plant 12 to 18 inches of space from its neighbors, and place tomato plants at least 18 to 24 inches away from the nearest strawberry. Tomatoes grow wide as well as tall—their branches can spread 2 to 3 feet depending on the variety—so measure from the center of the tomato plant's stem, not from where you expect it to stop.

Plant strawberries on the outer edges of the bed or in a separate row, and put tomatoes in the center or back row where their height won't shade the strawberries as the season progresses. If you're using containers, a 5-gallon pot works for one strawberry plant, and a 10-gallon pot or larger works for one tomato. Never plant them in the same pot—the tomato will outcompete the strawberry for water and nutrients.

Soil requirements and how they differ

Strawberries thrive in soil with a pH between 6.0 and 6.8 (slightly acidic), while tomatoes tolerate pH from 6.0 to 6.8 as well, so this is one area where they align well. Both plants prefer soil rich in organic matter—work in 2 to 3 inches of compost before planting. The real difference is drainage: strawberries need soil that drains quickly to prevent root rot, while tomatoes tolerate slightly heavier soil as long as it's not waterlogged.

Test your soil before planting if you can. A basic soil test from your local extension office costs little and tells you the pH and nutrient levels. If your soil is too acidic (below 6.0), add lime; if it's too alkaline (above 7.0), add sulfur. Both plants also benefit from a balanced fertilizer worked into the soil at planting time—something like a 10-10-10 formula—though tomatoes will need additional nitrogen as they grow.

Watering schedules and techniques

Strawberries have shallow roots that sit in the top 6 to 8 inches of soil, so they dry out faster than tomatoes and need water more often. Water strawberries every 2 to 3 days during dry spells, keeping the soil moist but not soggy. Always water at soil level, not overhead—wet leaves invite fungal diseases like powdery mildew and leaf spot, which spread quickly in humid conditions.

Tomatoes need deeper, less frequent watering. Water them once or twice a week, depending on heat and rainfall, but soak the soil to a depth of 8 to 10 inches so the roots grow down rather than staying shallow. Mulch around both plants with 2 to 3 inches of straw or wood chips to retain moisture and keep soil temperature steady. Keep mulch a few inches away from the tomato stem to prevent rot.

Managing disease and pest pressure

Strawberries and tomatoes don't share many pests, which is another reason they pair well. Strawberries attract spider mites and slugs, while tomatoes attract hornworms and whiteflies—different problems that don't compound each other. However, both plants are vulnerable to fungal diseases like powdery mildew and early blight, especially in humid climates.

Prevent disease by spacing plants far enough apart for air to circulate, watering at soil level only, and removing any leaves that touch the ground. If you notice spots on strawberry leaves or brown patches on tomato foliage, remove the affected leaves when ready and dispose of them in the trash, not the compost pile. In wet years, you may need to spray with a fungicide labeled for both crops—neem oil or sulfur work on most fungal problems—but start with good spacing and watering habits first.

When to remove strawberries to make room for tomatoes

Strawberry plants produce heavily for only 2 to 3 years, so plan to replace them every few seasons anyway. In a mixed bed, remove strawberry plants after you've harvested the last berries in early summer, usually by late June or early July depending on your climate. This gives tomatoes room to spread as they grow taller and fuller through mid and late summer.

Don't wait until tomatoes are full-sized to remove strawberries—by then the tomato's branches will be shading the strawberry bed, and the strawberry foliage will trap moisture around the tomato stem. Once strawberry harvest ends, pull the plants, add them to the compost, and let the tomatoes take over the space. You can replant strawberries in that same bed the following spring.

Container growing as an alternative

If your garden bed is small or you want more control over soil and spacing, grow strawberries and tomatoes in separate containers placed near each other. A strawberry tower or hanging basket keeps strawberries off the ground, where they're less vulnerable to slugs and soil-borne disease, and a tall tomato cage or stake next to it creates a neat, productive corner. Container growing also lets you move plants if one is shading the other more than expected.

Use potting soil, not garden soil, in containers—it drains better and stays lighter as plants grow. Water containers more often than in-ground plants because they dry out faster, especially in heat. Check soil moisture daily by pressing your finger an inch into the surface; if it feels dry, water until it drains from the bottom.

Frequently Asked Questions

Do strawberries and tomatoes need the same fertilizer?

Both plants benefit from a balanced fertilizer at planting time, but tomatoes need more nitrogen as they grow. Once strawberries start flowering, switch to a lower-nitrogen formula (like 5-10-10) to encourage fruit rather than leaves. Tomatoes can use a higher-nitrogen fertilizer early on, then switch to a lower ratio once they flower.

Can I plant strawberries under tomato plants to save space?

Yes, as long as you space them 18 to 24 inches apart and the tomato's branches don't shade the strawberries completely. Strawberries need at least 6 to 8 hours of direct sun daily. If your tomato plant grows very bushy or you prune it heavily, the strawberries below may not get enough light and will produce fewer berries.

What if my strawberries get powdery mildew while tomatoes are still growing?

Remove the affected strawberry leaves when ready and improve air circulation by spacing plants farther apart or removing some tomato foliage if it's blocking airflow. Spray with neem oil or sulfur early in the morning or late in the evening, following the label directions. If the problem spreads, remove the entire strawberry plant rather than risk infecting the tomatoes.

Can I plant strawberries and tomatoes in the same raised bed year after year?

Yes, but rotate crops within the bed to prevent soil depletion and disease buildup. Plant strawberries in one section one year, then move them to a different section the next year. Tomatoes can stay in the same spot if you replace the top 4 to 6 inches of soil each spring and add compost to restore nutrients.

How much sun do strawberries need if tomatoes are nearby?

Strawberries need 6 to 8 hours of direct sun daily to produce sweet, full-sized berries. If a tomato plant shades them for more than 2 to 3 hours in the afternoon, production will drop. Plant strawberries on the south or east side of the tomato plant so they get morning sun and afternoon shade in very hot climates.
