Strawberry in Zone 9A — Florida

Strawberries are a delicious and rewarding crop for Florida gardeners. Imagine plucking sun-ripened berries bursting with flavor straight from your garden – a taste far superior to anything you'll find in the store. Plus, they're incredibly versatile, perfect for snacking, desserts, jams, and more.

Our Florida gardening calendar is different, and while we face challenges like humidity and nematodes, our long 327-day growing season gives us a great window to successfully grow strawberries if we time things right. We can plant in fall, harvest in winter, and enjoy fresh berries before the real heat sets in.

Transplant your strawberry starts outdoors from mid January through early February here in Florida. This timing lets the plants establish themselves before our summers become too intense. Before planting, be sure to harden off your strawberry plants by gradually exposing them to outdoor conditions for about a week.

Space your plants 12-18 inches apart in well-draining soil. Keep an eye on the weather – a late cold snap is always possible, so be prepared to cover your young plants if temperatures dip unexpectedly.

Strawberries need consistent moisture, especially when they're fruiting. aim for about 1 inch of water per week, depending on rainfall. 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.

Water at the base of the plants rather than overhead. With our very-high humidity, wet foliage can quickly lead to fungal problems. Drip irrigation is ideal if you have it.

During our wet-summer months, you might not need to water at all, but check the soil moisture regularly. In the drier spring and fall, keep a close eye on your plants and supplement rainfall as needed. Signs of underwatering include wilting leaves and dry, shriveled berries. Overwatering can lead to root rot, so make sure your soil drains well. Mulch heavily around your strawberry plants to help retain moisture and suppress weeds.

Strawberry pruning is pretty minimal. Focus on removing runners unless you want the plants to spread. Clipping off these runners redirects the plant's energy into fruit production.

Throughout the growing season, snip off any dead or diseased leaves to keep the plants healthy. After your June-bearing varieties finish fruiting, you can "renovate" the bed by mowing off the foliage about an inch above the crown. This encourages new growth. As the first frost approaches in late December, remove any dead foliage to prevent disease over the winter.

You can expect your first strawberry harvest from mid April through late May. 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.

Gently grasp the stem just above the green cap and twist or snip it off, being careful not to damage the plant. Harvest regularly, every few days, to encourage continued production. Remove any overripe or rotting berries to prevent disease from spreading.

As the weather cools heading into late December, the plant will slow down and the berries will stop producing. Enjoy the last harvest and then clean up the garden by removing any dead foliage.

Here are some common problems Florida gardeners face with strawberries:

Gray Mold

• What it looks like: Fuzzy gray mold on berries, leaves, and stems. Berries may become soft and rotten.
• What causes it: A fungal disease favored by our high humidity and warm temperatures. Spores spread easily in wet conditions.
• How to fix/prevent it: Improve air circulation by spacing plants properly and pruning out dense foliage. Remove and destroy infected plant parts immediately. 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. 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 ripe strawberries!
• How to fix/prevent it: Netting is the most effective solution. Cover your plants with bird netting before the berries start to ripen. You can also try using visual deterrents like shiny tape or scarecrows, but they're often less reliable.

Strawberry Crown Borer

• What it looks like: Stunted plant growth, wilting, and eventual death of the plant. Small, white, legless grubs boring into the crown of the plant.
• What causes it: Adult beetles lay eggs in the crown of the strawberry plant, and the larvae feed on the crown tissue.
• How to fix/prevent it: Remove and destroy infested plants. Rotate crops. Plant nematode-resistant varieties. Apply insecticides if necessary.

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).

Florida Specific Challenges: Our hot heat, very-high humidity, and wet-summer rainfall create a perfect breeding ground for fungal diseases and nematodes, which can be especially problematic for strawberries. Choosing disease-resistant varieties, practicing good sanitation, and maintaining well-draining soil are crucial for success in our climate.

Good companions for strawberries in Florida include lettuce and spinach, as they provide ground cover and help suppress weeds, keeping the soil cool. Onions and garlic can deter pests with their strong scent. Thyme is a great herb that attracts beneficial insects. Borage is another good choice, attracting pollinators to your strawberry patch.

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