Blackberries are excellent fruits to grow in the home garden. There are many varieties of blackberries to grow, so find the right one for your climate and your needs. Blackberry plants are planted in the spring as soon as you can work the soil; however, it's best for the health of the plant not to produce fruit until the second year.
Figure out which USDA plant hardiness zone you live in. Visit the National Garden Association or Arbor Day Foundation website and search for your zone with your zip code. Buy blackberry plants that are hardy in your zone.
Decide between erect and trailing blackberry plants. Trailing blackberries need a trellis to grow; however, they produce more berries in a smaller space. Erect blackberries are usually more cold hardy and are often easier to grow. Also, consider whether you want your blackberry plants to have thorns. If you have small children or pets, you might want to grow ones without thorns.
Choose when you would like your blackberries to ripen for harvest. Blackberries are harvested during the summer and early fall; some varieties, such as Cheyenne, ripen early. Other varieties, such as Chester, ripen later. Purchase more than one variety for a longer harvest.
Select the type of fruit you want your blackberry plants to produce. Some cultivators, such as Apache, grow larger, firmer and sweeter blackberries than other plants. Others varieties, such as Sunberry, do not grow the largest or the sweetest berries, but are excellent for jams.
Purchase your blackberry plants from a nursery and choose ones with strong stems and leaves that look healthy. For trailing varieties, purchase one plant for every 4 to 10 feet. For erect varieties, purchase one plant for every 4 to 6 feet. Rows for all blackberry plants are spaced about 8 to 10 feet apart.
