Seasonal Care
Reduce watering as growth slows; clear fallen leaves to reduce disease pressure.
Feed with a high-potassium fertilizer as flower buds swell; protect from late frosts, which can damage blooms.
Water well in dry spells and carry out the summer prune, cutting whippy side shoots back to five leaves.
Carry out the second, harder winter prune while dormant, cutting side shoots back to two or three buds.
