Q.avocado trees
I have two avocado trees – 20 ft tall, but no fruit. Any suggestions? They’re very healthy looking but I’ve probably under fertilized. Used the correct stuff, but only a couple times a yr.
You could have a pollination issue as well as fertilizer.
Here are some links to help you pinpoint the issue.
