Is there a way to identify the gender of an ash tree before it reaches full maturity and the seed pods begin to form? I have some 2'-6' trees and would like to know which ones will be male and not make seed pods? Thanks Larry
On the assumption you mean Fraxinus sp., you need to wait for flowers to arrive; identification as male is usually confirmed when it fails to produce samaras, or seeds. Guidance on how to tell male from female flowers here http://homeguides.sfgate.com/identify-ash-tree-male-flowers-75506.html but it is not impossible for an Ash tree to produce both male and female flowers on the same tree, just on different branches.
