Chaste Tree Pruning Info
There are several reasons to prune a chaste tree. Left to their own devices, they grow 15 to 20 feet (4.5 to 6 m.) tall and 10 to 15 feet (3 to 4.5 m.) wide, but you can control the size through pruning chaste trees. You can also control the shape by chaste tree trimming. Carefully placed cuts can encourage the shrub to put on new growth. Another type of pruning, called deadheading, is important to keep chaste trees blooming all summer.
When to Prune Chaste Trees
The best time to prune a chaste tree is in late winter. Even if you’ve never pruned a tree or shrub before, you can prune a chaste tree. These trees are very forgiving and quickly grow back to cover mistakes. In fact, you can cut off the entire tree at ground level and it will regrow at an astonishing pace.
How to Prune a Chaste Tree
In spring and summer, clip off the spent flowers before they have a chance to go to seed. This allows the plant to put its resources into making flowers rather than nurturing seeds. If you remove the flower spikes throughout the first half of the season, the tree may continue blooming into early fall. In winter, remove weak, twiggy growth from the center of the plant to keep it looking tidy. This is also the time to prune to encourage branching. Make cuts all the way back to a side branch whenever possible. If you must shorten rather than remove a branch, cut just above a twig or bud. New growth will take off in the direction of the bud. Pruning chaste trees to remove the lower limbs that droop and hang close to the ground is optional, but if you remove these branches it will make lawn and garden maintenance much easier, and you’ll be able to grow ornamentals under the tree.
