Rainy Side Notes
Cornus kousa 'Big Apple' features very large fruit and textured dark green leaves. It resembles a raspberry but is a very firm fruit. The fruit is edible and will stay on the tree through October. Another tree, for pollination, is necessary if you want fruit.
Water deeply, 1 to 2 inches per week, during our drought period, especially if your tree is located in full sun.
