Hello All,

If using a crab apple for pollen purposes, is it better to have a full tree, 
or is a grafted branch sufficient?
Only a couple of trees involved that flower at different times, and a nearby 
tree being removed.

Also, does anyone have a web link to an authorative page that documents 
flower timing on the various crab
varieties?

Thanks,
Tom
