Rainier Cherry Plantation : Sea level & Temperature
What is the optimal height above sea level for planting rainier tree ? Also what is the optimal temperature for day and night for it to grow optimally for rainier tree ?
Outside United States
To my knowledge there are no special altitude or temperature requirements for Rainer Cherries. Any growing region which can produce sweet cherries should be able to produce Rainer. You need a winter with temperatures above -20F to avoid winter injury. You need about 1300 hours of temperatures of temperatures between 32 and 50 to complete the winter chilling requirement. Cherries bloom early and are susceptible to spring freezes. Very hot summer temperatures above 100 can result in doubled fruit the next year. I hope this helps.
