Leaving Almonds on the Tree After They Split Can Lead to Problems



Almond splitting



Q. We have an All-In-One almond tree with the shells just now starting to break through the skins. I was told that September is when the nuts are harvested. I’m wondering if you have a rule of thumb on harvesting these trees.



  



Green almonds at the right stage for harvesting

 A. You can start harvesting any time after the husk splits open. The sooner the better if you want to avoid problems. If you do not have ground squirrel problems that will steal the nuts from your trees. Insects will enter the split husk if you are not careful. If there is rain you run the risk of having the nuts mold after splitting. When you see them split, harvest and put them in a protected area in the shade to finish drying. Then you can leave them on the tree and let them Dry there. If you have ground squirrels, then it is best to begin to harvest them now and put them somewhere to dry. Ground squirrels can clean up the tree in one or two days. They will be all gone. Right now at the orchard ground squirrels have devastated most of the remaining almonds on the tree.

We harvested most of the almonds green last April. Green almonds are used in some Mediterranean recipes. We sold them through a broker to one of the San Francisco farmer markets for $4.00 a pound. Birds can also cause damage but ground squirrels are the worst. I have attached a picture of an Almond which is ready to harvest. Some almonds will split entirely open to the nut while others do not.
