Certain types of blackberry plants (such as the Oklawaha, Floridagrand and Brazos varieties) are native to Florida, and grow rapidly throughout the state. Blackberry plants are easy to grow in Florida and are relatively low maintenance. They are best planted in winter months, and harvested during the late spring. Growing blackberry plants in Florida is a simple process that does not require specialized skills as a horticulturist.
Prepare a strip of land approximately 5 feet wide for planting your blackberry bush. Ensure all weeds and brush have been cleared from the site where you plan to grow your blackberries.
Obtain a blackberry plant from a local farm or produce stand, or purchase a blackberry plant online if you are unable to locate a locally grown blackberry plant. For more information on purchasing blackberry plants online, see Resources.
Use your spade or shovel to uncover the earth on the site where you wish the blackberry plant to grow. It is not necessary to use fertilizer for blackberry plants in Florida, but if your garden soil is particularly dry you may use Miracle-Gro (found in major garden centers).
Plant your blackberry bush in the chosen spot in your garden. The blackberry plant roots should be moist when planted, and should be planted at least 9 inches underground. While blackberries can be planted at any time, the optimal time for planting blackberries in Florida is December through February.
Water your blackberry plants weekly. Prune the dead branches as needed. Dispose of any blackberries that have fallen off the plant, as the sweet, fermented nectar from the dead, rotting blackberries draw insects and birds to your blackberry plant.
Harvest the blackberries in April to June. Harvest blackberries by hand-picking them as needed.
