How long to grow a cherry blossom tree?
Define “grow.” Often they sit for the first year as they establish a new root system, but beginning the second or third year you will see new growth. Ideally you don’t want excessive growth each year as that produces weak wood. I’d be giddy with 7inches a year, but then I’m not in a prime plant growing region. Assuming you are in a better growing region, your soils are rich and moisture plentiful, a 6′ tree should be at about 10-12 feet tall in four years. By year 15-20 it should be near mature size,depending on species. Even when small, they are still beautiful and worth planting.
