Planting Leyland cypress
Leyland cypress is usually planted as part of a hedge, and is usually set up from the beginning of fall, but it can also be planted until the month of March-April as long as it doesn’t freeze.
After planting, you can also mulch the foot of the tree in order to avoid having weeds crowd it out from below but also to protect the roots from the cold.
- In both cases, maritime pine bark mulch is the most perfectly suited, but any other mulch will also play the part fine.
Pruning Leyland cypress, cypress hedges
If you cypress is never pruned, it can grow to reach nearly 65 feet (20 meters) and its bearing will be a distinctive cone.
For hedges, select the pruning height you are comfortable with as well as the thickness.
- Prune your Leyland cypress preferably at the end of summer or at the beginning of spring.
- Feel free to prune severely because cypress tends to grow very, very fast.
A heavy pruning end of August is enough to keep this growth under control.
That is also the season where sap descends and so it will slow the cypress’s growth a bit.
Spring pruning is usually with rising sap and tends to accelerate the tree’s growth, so this is ideal if you aim to hide yourself from prying neighbor’s view.
- Watch out for the growth of this conifer if you have neighbors because it can quickly become a problem.
