Is it true: in the wild, gambel oaks fruit only every 2 years, realizing one side of the canyon has acorns this year and the other side may be barren? Thanks, RWS

it was very helpfull for school work!!! cool

How old does a acorn tree have to be to produce acorns?

Hi Rick this is a possibility depending on conditions. Thanks, Su

Hi Dave this depends on the tree and conditions of course. I have read anywhere from 5 to 30 years! Thanks, Sue

Have been losing some large branches on very large oak.   Is ther a pest such as a borer vs fungus vs parasite damaging the tree?  Inspection shows nothing obvious. Thanks 

There is a possibility that there is something going on with your tree, however, without a photo, it is hard for me to tell. I suggest that you may want to contact a certified arborist in your area to take a look. Thanks for visiting our site, Suzanne
