Growing Blackberries in South Florida
Blackberries are perennial fruits that thrive in full sun and partial shade. Most varieties are self-fertile, but you can increase your yield by planting two or more varieties together.
Blackberries are widely used in cooking, especially in pies and jams. Because of their high sugar content, blackberries are also a popular fruit to grow as a hobbyist. There are several varieties of blackberries, including:
- Erect thornless blackberries
- Erect thorny blackberries
- Trailing thornless blackberries
For blackberries to thrive in South Florida, you should test the soil and water your blackberries accordingly. The best time to plant blackberries is in the spring, when the weather is still warm but not hot.
Blackberries are a perennial plant that can be grown from seed. They are easy to grow and will thrive in most of the climates in the U.S. It is possible to grow blackberries nearly anywhere so long as they receive full sun and regular watering.
Planting blackberries can be done directly in the ground or containers, with a minimum size of 2 feet x 2 feet. They will grow well in a container or window box if planted 2-3 inches deep and may not do well if they’re too close together. This plant needs to be planted in a large bed that is at least 4 feet wide, and 3-4 feet apart.
Blackberry can be grown indoors or outdoors, depending on your location. They can be propagated from cuttings or purchased directly from a nursery.
Blackberry Challenges
Blackberry growing is easy, but there are a few things to watch for:
1. Powdery mildew – This fungus can be a problem when blackberries are planted too close together or when they receive too much sunlight. If you find powdery mildew on your blackberry plants, you can control it with a preventative spray like Safer’s Soap or a copper sulfate or sulfur (available at most garden stores).
2. Blackberry canker – A fungal disease that affects the leaves and stems of blackberry plants. It usually appears as small brown spots that eventually turn brown and cause your plant to wither and die.
3. Blackberry rust – A fungal disease that affects the leaves and stems of blackberry plants, causing them to turn yellow.
4. Blackberry fruit flies – Fruit flies are attracted to blackberry and will lay their eggs in the flowers or on the ground near the plant. The fruit fly larvae then bore into the berries, causing them to rot before they reach maturity and are ready for harvest.
5. Root maggots – These small maggots emerge from rotting roots, eating through the roots as they grow. This can be a problem for blackberries planted in very-rich soils or in containers that are not kept well-drained.
Harvesting blackberries
Blackberry plants can be planted in the spring, but they will not bear fruit until the second or third year. The plant will produce fruit for 3 to 4 weeks between June and early September in many areas of the U.S.
Harvest twice a week once the blackberries are ready to be picked, and do so until the plant no longer produce fruits. A single bush can produce as many as 10 or 20 pounds of fruit per season.
When your blackberries are ripe and ready for picking, you can harvest them by cutting the limb with a sharp knife or by pulling up the plant and removing the berries from it. Simply leave them on their stems in a cool place where they’ll stay fresh longer (like an unheated garage) until they’re ready.
Remember, blackberries don’t ripen off their bush and shouldn’t be picked under-ripe. To freeze the blackberries, place them in an airtight container and store them in the freezer. Don’t wash the berries until you’re ready to use them for best results. This will keep the blackberries fresh longer and prevent rotting.
