The Q&A Archives: cross pollenization of fruit tree

Question: I bought 3 trees: 1 Royal Ann cherry, 1 4-n-1 cherry and 1 semi-dwarf fuji apple from our local Home Depot store. Do I need another cherry tree to pollenize the Royal Ann cherry? If so, what are your suggestions or will the 4-n-1 cherry do the job? Do I need another apple tree to pollenize the Fuji apple tree? If so, what are your suggestions? Can fruit trees cross-pollenize each other? Like, between cherry and apple trees? My last question is: is the 4-n-1 cherry sweet or sour? What are the 4 varieties in this cherry tree?

Thank you very much,

Answer: A cherry and an apple can not provide pollen for each other. For pollination you will need two types of apple that bloom at the same time, and two types of cherry that bloom at the same time.

Fuji does require a pollen source. Two apples often suggested as pollen sources for Fuji are Rome and Braeburn. However, if there is another apple tree or a crabapple tree nearby that blooms at the same time as your Fuji, then you would not need to plant your own.

Unfortunately, I do not have a list of which cherry varieties are included in the 4-n-1 you purchased. (Your local store may be able to tell you.) Stella or Lapins are good pollen sources for sweet cherries, so if one of those is included then you probably do not need another tree.

You may also want to check with your local County extension for routine care and maintenance suggestions for your fruit trees. Their web site is located here
