Rejuvenating Overgrown Japanese Yews by Hard Pruning

Can You Cut Yews Back to the Base?

20-year-old Japanese yews in a Chicago hedge have green tips but bare inner branches. The owner wants to know if severe cutback is possible.

Yes—With Proper Technique

• Cut Height: Reduce to 12–24 inches above soil level.
• Timing: Spring or late fall to minimize stress.
• Result: Yews readily push new growth from old wood.

What to Expect

The plants will look stark initially but will regrow into a dense, youthful hedge within a few seasons. Fertilize after pruning to support vigorous regrowth. Avoid summer pruning during heat stress.
