Strawberry in Zone 8B — Texas

Strawberries are a Texas gardener's delight, offering a burst of sweet, juicy flavor straight from your backyard. Imagine plucking sun-ripened berries for fresh snacks, pies, or jams, a true reward for your gardening efforts. Plus, they're surprisingly adaptable to our extended growing season, giving you a taste of spring even as the Texas heat starts to ramp up.

Sure, we have our share of challenges with unpredictable weather and blazing summers. But with smart planting and a little extra attention, you can absolutely enjoy a bountiful strawberry harvest. Our long 273-day growing season gives you plenty of time to get them established and producing before the worst of the summer hits.

Transplant your strawberry starts outdoors from mid February through early March. This timing lets them settle in before the Texas heat really kicks in. Whether you opt for bare-root or potted starts, make sure they've had a chance to gradually adjust to outdoor conditions by hardening them off for about a week.

Space your plants 12-18 inches apart to give them room to spread. Keep an eye on the forecast for any late-season freezes, which can happen even in late February. Be ready to cover your new transplants if a cold snap threatens.

Strawberries need consistent moisture, especially when they're fruiting. Here in Texas, that can be tricky with our unpredictable rainfall. Aim for about 1 inch of water per week, either from rain or irrigation. The "finger test" is your friend: stick your finger about 2 inches into the soil near the plant. If it feels dry, it's time to water.

Drip irrigation is ideal because it delivers water directly to the roots and avoids wetting the foliage. Wet foliage in our variable humidity can lead to fungal problems. Water at the base of the plants rather than overhead. In spring, with cooler temperatures, water every 2-3 days. As the Texas heat rises in summer, check daily and water deeply as needed, likely every day.

Signs of underwatering include wilting leaves and dry, crispy berries. Overwatering can lead to root rot, indicated by yellowing leaves and a mushy base. Mulch heavily around your strawberry plants to help retain moisture and suppress weeds. Pine straw or shredded hardwood mulch work well in our Texas climate.

Strawberry pruning is pretty straightforward. Throughout the growing season, remove any runners that your plants send out, unless you want them 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 1 inch above the crown. This encourages new growth for the following season. As the first frost approaches in late November, remove any dead or diseased foliage to prevent overwintering pests and diseases.

Expect your first strawberry harvest from mid May through late June, about 90 days after transplanting. The berries are ripe 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 (calyx) attached.

Gently twist or cut the stem just above the cap to avoid damaging the plant. Strawberries are continuous producers, so keep an eye on your plants and harvest regularly to encourage more fruit. As we get closer to the first frost in late November, any remaining green berries are unlikely to ripen, so you can remove them to allow the plant to rest.

Here are some common strawberry problems you might encounter in Texas:

• Gray Mold:
• What it looks like: Fuzzy gray mold on berries, leaves, and stems.
• What causes it: A fungal disease favored by cool, wet conditions and poor air circulation. Our variable humidity contributes.
• How to fix/prevent it: Remove infected plant parts promptly. Improve air circulation by spacing plants properly and pruning. Avoid overhead watering. Apply a fungicide if necessary.
• Slugs:
• What it looks like: Irregular holes in leaves, especially low-growing plants. Silvery slime trails on leaves and soil.
• What causes it: Gastropods that feed at night in moist conditions. They 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 strawberries!
• How to fix/prevent it: Cover plants with netting. Use bird-scaring devices like reflective tape or decoys.
• 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 plant.
• How to fix/prevent it: Remove and destroy infested plants. Rotate crops. Use beneficial nematodes to control larvae in 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 (unlike fusarium). 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).

Texas Specific Challenges: The hot-to-extreme Texas heat can stress strawberry plants, making them more susceptible to pests and diseases. Variable humidity and unpredictable rainfall can create conditions that favor fungal problems. Proper watering, good air circulation, and vigilant monitoring are key to keeping your strawberry plants healthy in our unique climate. And watch out for fire ants when you're tending your plants!

Good companions for strawberries include lettuce and spinach because they provide ground cover and help retain moisture. Onions and garlic deter pests. Thyme and borage attract beneficial insects that can help control pests.

Avoid planting strawberries near broccoli, cauliflower, pepper, and tomato. These plants can compete for nutrients or attract pests and diseases that can affect strawberries. For example, tomatoes and peppers are susceptible to verticillium wilt, which can also affect strawberries.
