Certain varieties may be started early in the season, to be followed by midseason bushes, and even late-season plants. Blackberry bushes may be proliferated by bending stems back to the ground during the growing season so that additional roots are generated where the stem comes in contact with the soil. The new plant can be trained to grow in another direction or may be attached to a different part of the trellis, leaving the new roots in tact. Another method used is to move the rooted plant to another location, thus transplanting it. In contrast, blueberry productivity is best stimulated by exposing existing bushes to the sun and giving them plenty of water, thus increasing the bearing of original plants rather than transplanting new ones.
Blueberry bushes require two gallons of water every week during the growing season.
It is no secret that birds love berries. To deter birds, aluminum pie plates or foil may be hung in the branches and vines so that the wind makes them swing. Stationary objects are useful for a while, but birds become familiar with those and often ignore them in time. In the event that the birds are getting more of the crop than you are, cover the ripening crop with netting. Most hardware stores carry the appropriate type.
