Strawberry in Zone 9B — Florida

Strawberries are a real treat in Florida. There's nothing quite like a homegrown strawberry, bursting with flavor that store-bought ones just can't match. They’re also surprisingly versatile: think fresh snacks, jams, desserts, or even a vibrant addition to your morning smoothie.

While our summers can be tough on many plants, the Florida gardening calendar is different, and strawberries thrive during our cooler months. With our long 344-day growing season, you can enjoy a rewarding harvest if you time things right.

Set out your strawberry transplants in early to late January. It's best to buy bare-root plants or potted starts from a local nursery. Don't bother with seeds, it takes too long.

Before planting, harden them off by gradually exposing them to the outdoors for about a week. This prevents shock. Space them 12-18 inches apart in well-draining soil.

Keep an eye on the weather. We can still get some chilly snaps this time of year, so be prepared to cover your plants if a frost is predicted.

Strawberries need consistent moisture, especially when they're fruiting. Aim for about 1 inch of water per week, but adjust based on rainfall. The "finger test" is your friend: stick your finger about 2 inches into the soil. If it feels dry, it's time to water.

Drip irrigation is ideal for strawberries in Florida. Our extreme humidity makes them prone to fungal diseases, and overhead watering just makes it worse. Water at the base of the plants to keep the foliage dry.

During our wet summers, you might not need to water at all. But during drier periods of fall and winter, keep a close eye on them. Wilting leaves indicate underwatering, while yellowing leaves can mean overwatering. Mulch heavily around your strawberry plants to help retain moisture and suppress weeds. Pine straw or wood chips work well in our sandy soil.

Strawberry plants don't need a lot of pruning. The main thing is to remove runners if you want the plant to focus its energy on fruit production. If you want more plants, let the runners spread and they'll root.

Snip off any dead or diseased leaves throughout the growing season to improve air circulation. After your June-bearing varieties finish producing (usually around late spring), you can renovate the bed by mowing off the foliage to about an inch above the crown.

As the weather cools down in late December, you don’t need to do any special pruning. Just let the plants rest and prepare for the next season.

Your first strawberry harvest should be in early April through mid May. The berries are ready to pick when they're fully red, fragrant, and have no white shoulders.

Gently grasp the stem just above the berry and twist. The berry should come off easily with the green cap still attached. Harvest in the morning for the best flavor.

Keep picking the ripe berries regularly to encourage the plant to produce more. As we head towards late December, the plants will naturally slow down their production as the weather cools.

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

Gray Mold

• What it looks like: Fuzzy gray mold on the berries, especially during humid weather.
• What causes it: A fungal disease that thrives in our very-high humidity.
• How to fix/prevent it: Improve air circulation by spacing plants properly and pruning away dead leaves. Use drip irrigation to keep foliage dry. Fungicides can help in severe cases.

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 strawberries as much as we do!
• How to fix/prevent it: Netting is the most effective solution. You can also try reflective tape or scarecrows.

Strawberry Crown Borer

• What it looks like: Wilting plants, stunted growth, and small holes in the crown of the plant.
• What causes it: A beetle larva that burrows into the crown, weakening the plant.
• How to fix/prevent it: Remove and destroy infested plants. Rotate crops. Insecticides can be used, but target the adults before they lay eggs.

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: The combination of hot heat, very-high humidity, and our wet-summer rainfall creates a perfect environment for fungal diseases and nematodes. Choose nematode-resistant varieties whenever possible and focus on good air circulation and drainage to combat fungal problems.

Good companions for strawberries include lettuce and spinach because they provide ground cover and help retain moisture. Onions and garlic deter pests. Thyme is said to repel strawberry crown borers. Borage attracts beneficial insects that can help pollinate your strawberries.

Avoid planting strawberries near broccoli, cauliflower, pepper, and tomato. These plants can compete for nutrients or attract pests that also affect strawberries. Plus, tomatoes are susceptible to verticillium wilt, which can easily spread to your strawberry patch.
