What is a good planting site for cherry trees?

Cherries perform best in moist, well-drained, fertile soils.  Avoid wet, poorly drained sites.  Cherries are susceptible to root rots in wet, poorly drained soils.  Trees should also receive full sun.  Sites must receive at least 6 hours of direct sun each day.  Sweet cherries bloom earlier than sour cherries.  As a result, the flowers on sweet cherries are more susceptible to damage from late spring frosts.  When selecting a planting site for sweet cherries, avoid planting in low spots where cold air settles on calm nights.  Also, avoid southern and western exposures that encourage early bloom.
