All roses produce fruit, though many varieties have been bred so the fruit is small and insignificant. Wild roses produce the largest fruits, but you can encourage fruit production on most any rose plant in your garden. The fruit, called hips, is a bright red and the shape depends on the variety of rose. Allow the flowers to die off and go to seed without pruning in order to encourage rose hip production. Use the hips in teas, syrups and jellies.
Stop cutting off the fading rose blooms in late summer, about two months before the bush stops blossoming. Allow the existing flowers to go to seed unmolested.
Pick the rose hips once they have matured from green to a deep red, purple or orange color depending on the variety. Feel the hips, and if they are soft and the proper color, they are ready for harvest. Hip harvest takes place once the nights begin to cool down in autumn.
Pick the hips from the plant. Remove any small stems that are attached to them.
Place the harvested hips into a colander. Rinse them thoroughly with cool water, then pat them dry with a paper towel.
Freeze the rose hips immediately after picking for later use or store them in the refrigerator for up to five days. Alternately, dry rose hips in a food dehydrator for use in teas.
