: I recently purchased a house that has several boxwoods that were planted as foundation plantings in 1960, and have become overgrown over time. How can I prune these to encourage growth on the lower branches, yet not jeopardize the health of the plant? They are otherwise healthy, but are much too tall, and need to be reduced in size by half, or more.
The top 1/3 of the plant can be "chopped" without harming the plant. The boxwoods are shaped like a "V" huh? We'll this happens when the top of the plant is allowed to grow without proper training. The tops of the boxwoods are getting the strongest light (9am-3pm), this is why the tops are bushy and the bottoms look empty. The key to full plants is light. What you want to do is "even out" the shrub, top and bottom, as much as possible in order to get the lower portion of the plant in more direct sunlight. Get the lower parts of the plant as much sun as possible by any means necessary. To keep the boxwoods shapely, "train" them by pruning the top portions each spring to a porportional width to the bottom portion. I hope this is clear.
