What factors most contribute to an apple tree being judged a good  
pollenizer? I've seen that description given to several crabs, even  
though their bloom season is over before a high percentage of other  
apples has started. I've seen the description coupled with "self  
pollenizer" occasionally, but only occasionally. If the tree has a  
huge number of blossoms is that a good thing because it is a powerful  
bee attractant or a bad thing because it may out-compete other trees  
with fewer blossoms?
