The types of pruning cuts to use depend on the outcome you desire. To make a yew tree bushier and fuller, just clip off the outer growth. This heading cut stimulates new growth and makes the tree look rounder and fuller. That said, if your yews have been neglected, they probably have grown leggy. If you want to know how to prune an overgrown yew like this, it’s not hard. You can snip back branches to the woody areas.
Key Takeaways:
- Yew trees are small, evergreen conifers often used in hedges.
- For a bushier, fuller yew, regularly trim off the outer growth.
- If a yew is overgrown, it’s likely now leggy. You’ll need to snip back branches to the woody area until it recovers. This could take years.
