Hello, I have a Osi Beni Japanese maple. I would like to know when the best time to trim up the tree and how to do so. Also is there any special care for this expensive tree? Thanx Matt

Winter, when your 'Oshio Beni' is still dormant is the time to prune. You can thin the canopy by removing entire branches, or you can simply shorten the branches when you prune. The branches have a natural drooping habit so I tend to simply shorten the branches that are too long and remove any that stick straight up and spoil the look of the canopy. Aside from regular deep watering, your Japanese maple won't need a lot of extra care. You can feed in the spring with a slow release 8-8-8 fertilizer. Enjoy your tree!
