🌳 Quick UK Pruning Rules to Remember

• Prune spring-flowering shrubs after flowering
• Prune late-flowering shrubs in late winter or early spring
• Avoid pruning in autumn, frost, heatwaves, or drought
• Never remove more than 20–25% of growth in one year

🧠 Key Takeaway

A successful UK pruning routine is about timing, restraint, and understanding plant cycles. Use winter for structure, spring for care, summer for control, and autumn for rest. When in doubt, prune lightly or wait — plants recover better from patience than mistakes.
