Q.please instruct on proper pruning of boxwood spheres
My 4 foot rounded box woods were just pruned into balls with lower branches trimmed inward.. I thought this would kill the plant, and it just need to slant ever so slightly inward.. help!

It's best not to turn inward at all. By leaving the top rounded and the sides in a gumdrop shape, it allows sun to reach all the leaves. If you must curve inward, just a slight indentation will help avoid the thinning and browning of the lower shrub. Also some thinning cuts, instead of just shearing, will allow more light inward.
