Strawberry in Zone 9B — Texas

Strawberries are a real treat in Texas, offering that sweet, juicy burst of flavor that's hard to beat, especially when the Texas heat starts ramping up. They're versatile too – perfect for snacking straight from the garden, making jams, or adding to desserts. Plus, there's nothing quite like the satisfaction of growing your own berries right here in the Lone Star State.

Sure, we have our share of challenges with unpredictable weather and the occasional extreme heat, but with a little planning and attention to timing, you can absolutely enjoy a bountiful strawberry harvest. Our long growing season, around 308 days, gives you a good window to get these berries established and producing.

You'll want to get your strawberry transplants into the ground from late January through mid February. This gives them a head start before the worst of the Texas heat arrives.

Before planting, be sure to harden off your transplants. Gradually expose them to outdoor conditions for about a week, increasing the amount of time each day.

Space your plants about 12-18 inches apart to give them room to spread. Keep an eye on the forecast – a late freeze can happen, so be ready to cover them if needed.

Strawberries need consistent moisture, especially when they're fruiting. They aren't drought-tolerant, so don't let them dry out completely. The goal is to keep the soil evenly moist, not soggy.

During the cooler months of spring and fall, you'll likely only need to water deeply once or twice a week, providing about 1 inch of water. In the heat of summer, you might need to water every other day, especially if we're experiencing a dry spell. Use the finger test – stick your finger about 2 inches into the soil. If it feels dry, it's time to water.

Drip irrigation is ideal for strawberries because it delivers water directly to the roots and keeps the foliage dry, which helps prevent fungal diseases. Water at the base of the plants rather than overhead, especially with our variable humidity. Yellowing leaves can mean overwatering, while wilting leaves indicate underwatering. Mulch heavily around your strawberry plants with straw or pine needles to help retain moisture and suppress weeds.

Strawberry pruning is pretty minimal, but it's important for a good harvest. Throughout the growing season, remove any runners (the little stems that sprout new plants) unless you want the plants to spread. Cutting off the runners redirects the plant's energy into fruit production.

For June-bearing varieties, renovate the beds after harvest by mowing or cutting back the foliage. This encourages new growth for the next season.

As the first frost approaches around early December, you don't need to do much pruning. Just remove any dead or diseased leaves to keep the plants tidy.

You can expect your first strawberry harvest from late April through early June, about 90 days after transplanting. The berries are ripe when they're fully red, fragrant, and have no white shoulders.

Gently pick the ripe berries with the green cap (calyx) still attached. Harvest in the morning for the best flavor, as the sugars will be most concentrated then.

To encourage continued production, pick the berries as soon as they ripen. As the first frost approaches in early December, harvest any remaining ripe or nearly ripe berries. You can also make strawberry jam or freeze the berries for later.

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

Gray Mold

• What it looks like: Fuzzy gray growth on berries, especially in wet weather.
• What causes it: A fungal disease that thrives in humid conditions. Texas's variable humidity and unpredictable rainfall can create ideal conditions.
• How to fix/prevent it: Improve air circulation by spacing plants properly. Remove infected berries promptly. 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 berries.
• What causes it: Birds love sweet strawberries!
• How to fix/prevent it: Cover plants with netting or use bird-scaring devices.

Strawberry Crown Borer

• What it looks like: Wilting plants, stunted growth, and small, white grubs inside the crown of the plant.
• What causes it: Larvae of a beetle that bores into the crown of the plant.
• How to fix/prevent it: Remove and destroy infested plants. Rotate crops. Use beneficial nematodes.

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).

Texas Specific Challenges: The combination of extreme heat, variable humidity, and unpredictable rainfall in Texas can create challenges for strawberry growing. The heat can stress the plants, making them more susceptible to diseases. The humidity can promote fungal growth. And the unpredictable rainfall can lead to either drought or waterlogged soil, both of which can harm strawberries. Careful monitoring and proactive management are key to success. And don't forget to watch out for fire ants when you're working in the garden!

Good companions for strawberries include lettuce and spinach. These leafy greens provide ground cover, helping to keep the soil cool and moist, which is especially beneficial during the Texas heat. Onions and garlic are also good choices, as their pungent aroma can deter pests. Thyme and borage are beneficial herbs that attract pollinators and beneficial insects to your garden.

Avoid planting strawberries near broccoli, cauliflower, peppers, and tomatoes. These plants are susceptible to verticillium wilt, a soil-borne disease that can also affect strawberries. Planting them together increases the risk of spreading the disease.
