Strawberry in Zone 10A — Florida

Strawberries are a real treat in Florida, offering that burst of homegrown sweetness that store-bought berries just can't match. Imagine plucking sun-ripened strawberries from your garden in early spring – perfect for snacking, adding to smoothies, or making a delicious jam.

Our Florida gardening calendar is different, and while the summer is the slow season, we can still enjoy strawberries if we time it right. With our long, 355-day growing season, planting in fall and harvesting in winter gives us a sweet advantage, despite the challenges of humidity and sandy soil.

Transplant your strawberry starts outdoors from late December through mid January. This gives them plenty of time to establish before our brief "winter" ends.

Before planting, harden off your strawberry plants by gradually exposing them to outdoor conditions for about a week. This helps them adjust to the Florida sunshine and temperatures.

Space your strawberry plants 12-18 inches apart to allow for good air circulation, which is crucial in our humid climate. Keep an eye on the weather forecast around transplant time; even though we're in Zone 10A, we can still get a cold snap that might require covering your young plants.

Strawberries need consistent moisture, especially when they're fruiting, but our high humidity means you have to be careful not to overwater. Aim for about 1 inch of water per week, but adjust based on rainfall.

Use the finger test to check soil moisture: stick your finger about 2 inches deep into the soil near the base of the plant. If it feels dry, it's time to water.

Water at the base of the plants rather than overhead to prevent fungal diseases, which thrive in our humid environment. Drip irrigation is ideal. Signs of underwatering include wilting leaves and dry, crispy edges. Overwatering can lead to yellowing leaves and root rot.

Mulch heavily around your strawberry plants with pine straw or wood chips. This helps retain moisture, suppress weeds, and keep the berries clean.

Strawberry pruning is pretty minimal, which is great for us Florida gardeners. Focus on removing runners – those long, stem-like growths that the plant sends out.

If you want more plants, let the runners root, otherwise cut them off to direct the plant's energy into producing more fruit. If you have June-bearing varieties, give the plants a "renovation" after harvest by mowing off the foliage to about an inch above the crown. This encourages new growth.

As our first frost approaches around late December, remove any dead or diseased foliage to help prevent fungal problems over the winter.

You can expect your first strawberry harvest from late March through early May. The berries are ready to pick when they're fully red, fragrant, and have no white shoulders.

Gently pick the berries with the green cap (calyx) attached to help them last longer. Harvest in the morning for the best flavor, as the sugars will be most concentrated then.

To encourage continued production, pick the ripe berries regularly. As the first frost approaches in late December, harvest any remaining ripe berries and consider covering the plants if a hard freeze is predicted.

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

Gray Mold

• What it looks like: Fuzzy gray mold on the berries, flowers, and leaves.
• What causes it: Fungal disease favored by high humidity and wet conditions – a common problem in Florida.
• How to fix/prevent it: Improve air circulation by spacing plants properly. Water at the base of the plants. Remove infected plant parts promptly. Consider a fungicide if the problem is severe.

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 strawberries!
• How to fix/prevent it: Cover your plants with netting or use bird-scaring devices.

Strawberry Crown Borer

• What it looks like: Wilting plants, stunted growth, small holes in the crown of the plant.
• What causes it: Small beetles that lay eggs in the crown of the plant; the larvae then feed on the crown.
• How to fix/prevent it: Remove infested plants. Rotate crops. Use beneficial nematodes to control the 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. 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).

Florida Specific Challenges: Our hot, humid summers and sandy soil can exacerbate these problems. Be vigilant about watering, air circulation, and soil health to keep your strawberries healthy and productive. Nematodes can also be a problem in sandy soils, so consider using nematode-resistant varieties or soil amendments to improve soil health.

Good companions for strawberries include lettuce and spinach. They provide ground cover and help retain moisture, which is helpful in our sandy Florida soil. Onions and garlic deter pests, and thyme and borage attract beneficial insects that can help control strawberry pests.

Avoid planting strawberries near broccoli, cauliflower, pepper, and tomato. These plants can compete for nutrients or attract pests that also affect strawberries. They can also be hosts for verticillium wilt, which can easily spread to your strawberry plants.
