A combination cherry tree is a single tree where multiple compatible cherry varieties have been grafted onto the same rootstock, providing a diverse, extended harvest and cross-pollination benefits from a single plant. Self-Pollinating: The main advantage is that the different varieties on the same tree pollinate each other, eliminating the need to plant a second separate tree.Space-Saving: They are ideal for small yards or urban gardens where space is limited.Extended Harvest: Varieties are often chosen to ripen at different times, allowing you to enjoy fresh cherries from late spring through the end of summer.Variety: You can enjoy both sweet and tart cherries from one tree, with common varieties including ‘Bing’, ‘Rainier’, ‘Montmorency’, ‘Stella’, ‘Van’, and ‘Sweetheart’.Care: The primary maintenance for a combination tree is to ensure all grafted branches grow at a balanced rate to prevent one vigorous variety from dominating and overtaking the others.
