Watering is not recommended after early September, unless the soil is very dry. Remove blossoms the first 2 years after planting to stimulate vigorous vegetative growth. Pruning is not necessary until the 4th year. Prune out dead and weak branches and thin terminal wood with small buds. Before harvesting, taste a few berries to check for ripeness.
Some berries appear ripe, but they can still be quite sour.
Sanitation, proper siting and chemicals labeled for the problem and the crop provide adequate control.
