Last year I started a Mother's Day tradition by picking out a Japanese maple with my husband and son—Red Pygmy. This year I picked out a Mikawa yatsubusa that I'd been dreaming about for the last year. My son (25) had the same idea. A year ago he ordered a two-year graft online from Amazon of all places. He'd been taking care of it for the past year, hiding it whenever I came to visit. We expanded a perennial bed to make space for this embarrassment of riches. The older tree is 40" tall and about 42-43" wide. The younger one is 18" tall and in a pot. Two questions: 1. At what age to Mikawa yatsubusa begin to branch out? 2. Do any of you have recommendations for a maple that would be a good complement to the Mikawa yatsubusa? A tree that is dramatic in its own right and won't get too large. The bed is in full sun. I welcome your suggestions.
