Strawberry in Zone 7A — Southeast

Strawberries are a real treat in the Southeast, offering a burst of sweetness that's especially satisfying after our long, hot summers. Imagine fresh strawberry shortcake, homemade jam, or just popping them straight from the garden – a taste of pure sunshine you can't beat. Plus, they thrive here, making it extra rewarding.

We definitely have our share of gardening challenges in the Southeast, like humidity and fungal diseases, but with a little planning, you can absolutely grow fantastic strawberries. Our long 225-day growing season gives you plenty of time to get a good crop, and the reliable summer rain can be a real blessing if managed right.

Transplant your strawberry starts outdoors from mid-March through early April. Before you plant, be sure to harden off your bare-root or potted plants by gradually exposing them to outdoor conditions for about a week. This helps them adjust to the full sun and temperature fluctuations.

Space your plants 12-18 inches apart to give them room to spread. At this time of year, we can still get some temperature swings here in the Southeast, so keep an eye on the forecast and be ready to cover them if a late frost threatens.

Strawberries need consistent moisture, especially when they're fruiting. Drip irrigation is your best friend here in the humid Southeast, as it delivers water directly to the roots and helps keep the foliage dry, reducing the risk of fungal diseases. Mulch heavily around your plants with straw or pine straw to conserve moisture and suppress weeds.

During the spring growing season and fruiting, aim to give your strawberry plants about 1 inch of water per week, either from rainfall or irrigation. Use the "finger test" – stick your finger about 2 inches into the soil near the base of the plant. If it feels dry, it's time to water. In the hot summer, you may need to water more frequently, especially if we're in a dry spell. Water at the base of the plants rather than overhead to avoid creating a humid environment around the leaves.

If your strawberry leaves start to turn yellow and wilt, you're likely overwatering. If the leaves are dry and crispy, you're underwatering. Adjust your watering schedule accordingly.

Strawberry pruning is pretty minimal. The main thing is to remove the runners – those long, slender stems that the plants send out. If you want to encourage more fruit production, snip off the runners to direct the plant's energy into the berries.

You can also let some runners spread if you want to propagate new plants. For June-bearing varieties, renovate the beds after harvest by mowing off the foliage about an inch above the crown. This encourages new growth. As the first frost approaches around early November, clear away dead or diseased foliage to prevent overwintering pests and diseases.

You can expect your first strawberry harvest from early June through late July, depending on the variety and when you transplanted. The berries are ready to pick when they are fully red, fragrant, and have no white shoulders near the stem.

Gently twist or snip the berries off the plant, leaving the green cap attached. Harvesting in the morning, after the dew has dried, will give you the best flavor. Keep picking the ripe berries regularly to encourage the plant to keep producing.

As the weather cools in late fall and the first frost approaches around early November, harvest any remaining berries and consider covering the plants with a layer of straw or pine needles for added winter protection.

Here are some common problems you might encounter with strawberries in the Southeast:

Gray Mold:

• What it looks like: Fuzzy gray mold on the berries, especially after wet weather.
• What causes it: A fungal disease that thrives in humid conditions, common during our wet summers.
• How to fix/prevent it: Improve air circulation by spacing plants properly and pruning away dead leaves. Apply a fungicide if necessary, but focus on prevention.

Slugs:

• What it looks like: Irregular holes in leaves, especially low-growing plants. Silvery slime trails on leaves and soil. Damage worse at night and in wet weather.
• What causes it: Gastropods that feed at night in moist conditions. Hide under mulch, boards, and debris during the day.
• How to fix/prevent it: Beer traps (shallow dish of beer sunk into soil). Iron phosphate bait (pet-safe). Remove hiding spots. Water in morning so soil surface dries by evening. Copper tape around beds. Diatomaceous earth around plants.

Birds:

• What it looks like: Missing berries, pecked fruit.
• What causes it: Birds love strawberries just as much as we do!
• How to fix/prevent it: Cover your plants with netting before the berries start to ripen. Shiny deterrents like pie plates or reflective tape can also help.

Strawberry Crown Borer:

• What it looks like: Wilting plants, stunted growth, and small, white grubs inside the crown of the plant.
• What causes it: A beetle larva that tunnels into the crown of the strawberry plant.
• How to fix/prevent it: Remove and destroy infested plants. Rotate strawberry beds. Insecticides can be used, but are best avoided if possible.

Verticillium Wilt:

• What it looks like: Lower leaves yellow, wilt, and die, progressing upward. One side of plant may be affected first. Brown streaks in stem cross-section.
• What causes it: Soil-borne fungus that persists for years. Cooler soil temperatures favor it. Wide host range.
• How to fix/prevent it: No cure — remove infected plants. Rotate with non-susceptible crops (corn, grains). Solarize soil. Plant resistant varieties (look for 'V' on labels).

Southeast Specific Challenges: Our hot, humid summers and frequent rainfall create a perfect environment for fungal diseases to attack strawberries. Good air circulation, proper watering techniques, and disease-resistant varieties are key to success. Don't forget to protect your plants from deer and Japanese beetles, which can also be a problem in our region.

Good companions for strawberries include lettuce and spinach, which provide ground cover and help keep the soil cool and moist. Onion and garlic can help deter pests. Thyme and borage attract beneficial insects that prey on strawberry pests.

Avoid planting strawberries near broccoli, cauliflower, pepper, and tomato. These plants can compete for nutrients or attract pests and diseases that also affect strawberries.
