When should I cut back blackberry bushes?
After the canes have produced fruit, you should prune them back to the ground to leave room for the stronger, 1-year-old canes. Some pruning should be done every spring to keep the plants from becoming tangled and to improve their ability to bear. Prune trailing blackberries in the spring for good growth habits.
How do you take care of blackberry bushes in the winter?

Where do blackberries grow best?
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.
How long do blackberry bushes live?

Why is my blackberry bush not producing fruit?
Environmental Factors Keep Blackberries from Fruiting Lack of Pollinators – Limit the use of pesticides around the blackberry bushes to make sure that pollinators can get to the plants. Heredity – Make sure that you only purchase quality varieties from reputable nurseries.
Do blackberries grow on old or new wood?
Blackberries only produce fruit on canes that are two years old, so once a cane has produced berries, it will never produce berries again. Cutting these spent canes off the blackberry bush will encourage the plant to produce more first year canes, which in turn will mean more fruit producing canes next year.
How do you grow erect blackberries?
Erect hedge forming blackberries can be planted as plants or as root pieces. Rows are usually spaced 10 feet apart. If plants are used, space them from 2 to 4 feet apart in the row. Dig a hole that is large enough to spread the roots out evenly, cover with soil, and firm soil around the plants.
Can blackberry plants grow in pots?
Choose a pot as large as 24″ to 36″ across or even a half whiskey barrel. As blackberries grow, over time each original stem sends up more shoots from the roots to form a patch. A larger pot gives your berries ample space to spread and yield more stems, which means more fruit.
Do blackberry plants spread?
Blackberries spread by underground stems called rhizomes, which grow a few inches below the soil surface. When the tip of a rhizome contacts the fibrous inner wall of the RootTrapper® container it is trapped, cannot go through the fabric and as a result, the tip stops growing.

How do you encourage wild blackberries?
“Proper soil drainage and site preparation, as well as a trellis or other means of allowing good circulation to the canes, are also important for establishing blackberries.” Training plants to grow on trellises, walls and fences or row cropping the blackberry patch also helps maintain some control.
How much space does a blackberry bush need?
Each blackberry plant requires 2.5 to 3 feet of free soil rooting area to develop into a healthy, productive plant. Most blackberries are sold as root cuttings.
