Blackberry plants are created by splicing. Like fruit trees, although they can be grown from a seed, the process is long, and the plants that result do not produce quality fruit.
Blackberries grow best in full sunlight and organic soil. They should be planted in early to late spring, after the danger of frost has passed. The soil should be kept moist but not soggy. Blackberries grow best in a straight line along a trellis or other guide. This is called a hedgerow. The blackberry plant will send its canes along the hedgerow. -
Blackberry plants have roots that are perennial (or live indefinitely); however, blackberries only bear fruit on biennial canes. Each year, the roots send up branches or stalks, called canes, that produce fruit the second year, then die. Any cane producing fruit is a second year cane. They usually are covered with a very thin, greenish-brown bark. First year canes are bright green and will not bear fruit.
Although blackberry canes are relatively short-lived, the plants and roots themselves are quite hardy. The roots spread rapidly, producing canes that are very strong and can grow through almost anything, including a tiny crack in concrete. The canes can also grow a long distance underground before emerging at the surface, which means it can be very difficult to get rid of or kill a wild blackberry plant. - Blackberries bloom in the summer, and shortly after blooming the berries start to develop. They are tiny, hard and green at first. Slowly, they turn from green to red, and from red to a deep reddish-black. They are usually ready to harvest in August or early September, depending on your region. When a blackberry is ready to be picked, it will be big, black and shiny. It will also detach easily from the core. Blackberries, like all other bramble fruit, do rot quickly once ripe. For that reason, they should be picked often, as soon as they are ripened.
