How far apart should blackberry rows be?
Trailing blackberry plants should be spaced about 10 feet apart in the row. This allows the plants to grow about 5 feet in either direction. Spacing for erect plants, not trellised and maintained about 3 feet tall, would be about 3 feet apart.
How much space do blackberries need?
Cuttings of erect-habit blackberries should be spaced 2 to 4 feet apart in rows. Canes will then fill in the spaces between plants as they grow. Semi-erect and trailing varieties need 4 to 10 feet between plants to accommodate their very long canes.
How tall should a blackberry trellis be?
After setting, the posts should be about 6 feet tall. Either two- or three-wire trellis systems are generally used. A two-wire trellis system is usually adequate, with the top wire at approximately 5 to 6 feet above the ground and the bottom wire at approximately 31⁄2 feet above the ground.
Do blackberries need trellis?
Blackberries require trellising to support the canes, keep fruit off the ground and protect canes from wind damage. The exception is ornamental, dwarf, everbearing, erect cultivars; these also produce much lower yields (see “Harvest,” page 13).
What can you not grow near blackberries?
Blackberries should not be cultivated in soil that has previously grown tomatoes, potatoes, eggplant, peppers, strawberries, or any other type of berry bush or bramble.
Do you need 2 blackberry plants?
Blackberries and their hybrids are all self-fertile, so multiple plants are not needed for fruit production.
How many blackberry bushes should I plant?
All blackberries grow best in full sun, and almost all varieties are self-fruitful, meaning that you need to plant only one cultivar. As a rule of thumb, five or six plants will produce enough berries for a family of four. Each blossom will produce a sweet, juicy blackberry.
How do you train trailing blackberries?
Prune trailing blackberries in the spring for good growth habits. Prune each main cane back to 3-4′. Then cut back side branches to about 12”, leaving five or six buds on each. Erect and semi-erect varieties should be tipped or cut back to 3-4′ in midsummer.
What is a good companion plant for blackberries?
Low-growing groundcover plants, including any variety of mint, lemon balm, bee balm, hyssop, borage, thyme, or chives, are excellent companion plants for blackberries. They attract bees for pollination and help repel foliage and fruit predators, keeping beetles and mice away from your blackberry crop.
Where is the best place to plant blackberries?
full sun
Choose a site that is in full sun and has plenty of room for the ramblers to grow. If you put them in too much shade, they won’t produce much fruit. The soil should be a well-draining sandy loam with a pH of 5.5-6.5. If you lack an area with sufficient drainage, plan on growing blackberry bushes in a raised bed.
