Pruning Horse Chestnut Tree
I have a horse chestnut (pink flowers) that is 8-10 feet tall, planted 3-4 years. It looks like it should be shaped with some pruning. Is it okay to do this? How much can I cut off?

Shaping is just a matter of pruning until the shape of the plant is pleasing to you. However, try not to take more than a third of its growth off the branches. Also, be sure to cut any dead or unsightly limbs. It is best to wait until late summer or early autumn to prune.
