Ornamental cherry trees rarely produce fruit but their bold flowers provide nourishment to early season pollinators. These deciduous trees are hardy in Zones 5 to 9 and grow best in full sun.

Whether the tree is inside or outside, give it full sunlight every day and 10 oz. of a fertilizer such as Espoma Organic Citrus-tone 5-2-6 each February, May, and August.

If space allows, consider planting a sour cherry tree in your backyard. Sour cherries do need a cold period with air temperatures between 34 and 45 degrees to initiate flowering for fruit development.
