Put on thick leather gloves. Wipe the pruning shear blades with rubbing alcohol to sterilize them.
Prune spindly, dead and damaged stems on one- to three-year old gooseberries in early spring before growth begins. Prune the stems at ground level, and sterilize the pruning shears again after use.
Prune gooseberries four years old and older in early spring, pruning the weakest and the oldest stems at ground level. The oldest stems are thicker and darker than the others. Leave nine to 12 stems per bush. Alternatively, prune all the stems at ground level, which encourages gooseberries to produce large fruit.
Prune gooseberry stems suffering from powdery mildew if they become infected during the growing season. Powdery mildew is a fungal infection that causes white, powdery patches, poor growth and death. Prune 3 inches below the infected area, cutting just above a leaf node. Leaf nodes are raised bumps on stems where new growth sprouts. Put gooseberry stems and fruit suffering from powdery mildew in a sealed plastic bag in the trash.
