Strawberry in Zone 7B — Southeast

Strawberries are a true delight in the Southeast, offering sweet, juicy rewards after our long summer days. Nothing beats a homegrown strawberry still warm from the sun, and they're incredibly versatile – perfect for snacking, jams, desserts, or freezing for later. Plus, the satisfaction of growing your own berries is hard to beat.

We definitely have our challenges here in the Southeast with the hot and humid weather, which can lead to disease pressure. But with careful timing and the right strategies, you can absolutely enjoy a bountiful strawberry harvest. Our long 235-day growing season gives you plenty of time to get it right.

Transplant your strawberry plants outdoors in early to late March. This gives them plenty of time to get established before the real heat hits. Before planting, be sure to harden off your transplants by gradually exposing them to outdoor conditions for about a week.

Space your plants 12-18 inches apart to allow for good air circulation. Keep an eye on the weather forecast around transplant time, as we can still get some late frosts in early spring. A frost blanket can be your best friend. Remember, it's best to buy bare-root plants or potted starts in the spring, as growing strawberries from seed can be a slow and unreliable process.

Strawberries need consistent moisture, especially when they're fruiting. They aren't drought tolerant, so don't let them dry out completely. However, in our humid climate, it's crucial to avoid overhead watering as much as possible, since wet foliage can quickly lead to fungal problems. Drip irrigation is ideal, delivering water directly to the roots.

During the spring, when temperatures are milder, aim for about 1 inch of water per week, either from rainfall or irrigation. As the summer heat intensifies, bump that up to 1.5-2 inches per week. The "finger test" is a great way to check: stick your finger about 2 inches deep into the soil. If it feels dry, it's time to water.

Overwatering can lead to root rot, indicated by yellowing leaves and wilting, while underwatering will cause the leaves to become dry and crispy. Always water at the base of the plant, avoiding getting the leaves wet. Mulch heavily around your strawberry plants with pine straw or shredded leaves to help retain moisture and suppress weeds.

Strawberry plants don't require a lot of pruning, but a little maintenance goes a long way. Throughout the growing season, remove runners as they appear unless you want the plants to spread and create new plants. Removing the runners directs the plant's energy into fruit production.

For June-bearing varieties, renovate the beds after harvest by mowing or cutting back the foliage to about an inch above the crown. This encourages new growth and better yields the following year. As the first frost approaches in early November, remove any dead or diseased foliage to help prevent overwintering pests and diseases.

You can typically expect your first strawberry harvest from early June through mid July here in Zone 7B. The berries are ready to pick when they are fully red, fragrant, and have no white shoulders. Pick them in the morning for the best flavor, and be sure to leave the green cap attached.

Gently twist or snip the stem just above the cap to avoid damaging the plant. To encourage continued production, pick the ripe berries every few days. As the end of the season approaches and the first frost threatens in early November, harvest any remaining berries, even if they're not quite fully ripe – they can still be used for jams or preserves.

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

• Gray Mold:
• What it looks like: Fuzzy gray mold on berries, leaves, and stems.
• What causes it: High humidity and poor air circulation create ideal conditions for this fungal disease.
• How to fix/prevent it: Improve air circulation by spacing plants properly and pruning excess foliage. Remove infected plant parts promptly. Apply a fungicide if necessary, following label instructions carefully. Avoid overhead watering.
• 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 or pecked-at berries.
• What causes it: Birds love ripe strawberries!
• How to fix/prevent it: Cover your strawberry plants with netting to protect the berries from birds.
• Strawberry Crown Borer:
• What it looks like: Wilting plants, stunted growth, and small white grubs inside the crown of the plant.
• What causes it: Adult beetles lay eggs in the crown, and the larvae feed on the plant tissue.
• How to fix/prevent it: Remove and destroy infested plants. Rotate crops. Apply beneficial nematodes to the soil.
• 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 wet-summer rainfall create ideal conditions for fungal diseases like gray mold. Good air circulation and proper watering techniques are essential for preventing these problems. Also, deer can be a nuisance, so consider fencing or deer repellent.

Companion planting can be a great way to improve the health and productivity of your strawberry patch. Lettuce and spinach are good companions because they provide ground cover, helping to suppress weeds and retain moisture. Onions and garlic repel pests like aphids and spider mites.

Thyme is a beneficial herb that can help deter strawberry crown borers. Borage attracts beneficial insects like bees, which can improve pollination. Avoid planting strawberries near broccoli, cauliflower, pepper, or tomatoes, as these plants can compete for nutrients or attract pests and diseases that can affect strawberries.
