Fragrant white flowers bloom from late winter to early spring and turn into small, green berries. As the berries ripen, they change from red to black or purple by mid to late spring. These are some of the first berries you can harvest each year. When they are dark and fully ripe, they hold tightly to the plant and can be easily squashed, so handle them carefully when picking.

Be sure to consider their growth habits when selecting a site for dewberries. They can easily turn into a thicket that can be challenging to manage.
 
You can grow dewberries from seeds or cuttings. Plants should be installed in early spring and spaced three feet apart. They are best trained up a trellis, protected from strong winds. They prefer full sun but can also be grown in partial shade. This is especially true in areas with scorching hot summer temperatures.
 
It takes a few years for dewberries to start producing fruit, but once they do, you will probably have a lifetime supply. Dewberries can also be grown in large containers. In either case, they will benefit from top dressings of aged compost.
 
Aphids, cane borers, dewberry mites, leaf beetles, peach blossom moths, and spider mites may be attracted to your dewberries. So will chipmunks, deer, fox squirrels, raccoons, white-footed mice, and many other mammals. But these plants are rugged. Overwatering and poor drainage are more likely to cause fungal problems, such as blight, downy mildew, fruit, root, and stem rots. As with other bramble fruits, remove spent canes with a pair of high-quality bypass pruners to improve air flow and promote new growth.
