Sweet cherries are the ones most often found in markets. They have a thick, rich, and almost plumb-like texture. Traditionally, sweet cherry trees are self-sterile and best for an orchard or a large garden. You'll need at least two or three trees so that they can pollinate each other. However, a recent and exciting development in sweet cherries is the dwarf self-pollinating "Stella." (See image below.)
Sour cherries are not usually eaten raw, but are widely used for preserves and other cooking uses. Sour cherries are much smaller than sweet cherries and all varieties are self-fertile.
Standard-size trees start bearing fruit in their fourth year and can produce 30 to 50 quarts of cherries each year.

- Space fanned trees 15 to 18 feet apart.
- Planting for sour cherries is the same as for sweet cherries, however, space bushes and fans only 12 to 15 feet apart.
