Growing Strawberries ……………..

Did you know Florida is the strawberry capital of the world during winter?

Florida strawberries can be planted in home gardens beginning in the fall and enjoyed through the winter and spring.

Growing Conditions

Strawberries need temperatures between 50°F–80°F and less than 14 hours of daylight to flower and produce fruit. In Florida, these conditions occur throughout the fall, winter, and spring.

Strawberries in Florida are planted in September to early November, and flowering and fruit continue through April or May. Fruit set will not be constant, but will have two or three cycles, and can be interrupted by freezes.

Site & Planting

Grow strawberries in a full-sun location with at least eight hours of direct sunlight. You can plant strawberries in rows in raised beds or in planter boxes, pots or other containers. Just make sure your planting spot has good drainage.

Before planting, mix in two pounds of a fertilizer containing nitrogen, phosphorus and potassium per 10 feet of soil.

Use transplants for planting. (Bareroot transplants are the most common, but you may also find plug (container) transplants in plastic trays or pots at garden centers.)

Many growers plant strawberries in raised beds with black plastic mulch for weed control and to keep soil off the berries. Set your transplants through slits in the mulch. Make sure you do not cover the crowns of transplants.

Freeze Protection

Temperatures below 32°F will damage the fruit and flowers of strawberry plants, but the crowns and leaves will survive to temperatures in the low 20s if they have been acclimated to cool weather.

If a freeze comes along, protect the plants by covering them with old sheets or a commercial row cover during the afternoon and all night. Anchor the coverings so that the wind does not blow them off the plants.

Disease & Pests

Using healthy transplants is one of the best defense strategies for keeping diseases and pests from destroying your strawberries. Purchase plants from reputable nurseries or garden centers.

Most diseases on leaves, flowers or fruits can be controlled with fungicides for home garden use. Make sure the label specifies that it can be used on strawberries and follow all label directions. Be sure to remove dead and diseased leaves from the plants to reduce infection.

Control powdery mildew with applications of sulfur. Make sure temperatures are cooler than 80°F before applying sulfur, or it will cause burns on fruit and foliage.

Insects on strawberry plants will change with the season. Caterpillars are found early in the season. Aphids and thrips appear later. Spider mites are a persistent pest — look for them around December.

Nematodes and soil-borne diseases can cause problems if you plant your strawberries in the same spot each year. Switch your planting areas, and avoid planting strawberries in spaces where tomatoes, eggplant or other vegetables susceptible to verticillium wilt have just been grown.

Harvesting

Strawberries are ready to harvest when three-quarters of the berry’s surface is red. Once the fruit is completely red, it rots quickly, so be sure to harvest regularly (usually every two to four days).
