Pruning and caring for Chamaecyparis
You may equalize the tree 1 or 2 times if needed. Clean it up at the end of winter.
Chamaecyparis stands pruning very well, which makes it possible to shape it as you wish, and to prune it as often as you care to in order to keep its shape.
Water regularly during the first 2 years after planting, if it doesn’t rain of course.
After that, it will only need to be watered in case of extended dry spell or strong heat.
Over the first few seasons, you can amend the soil with conifer-specific fertilizer in order to spur proper growth.
