Almond tree harvest

Asked October 24, 2016, 2:46 PM EDT

I planted 2 Almond trees about 7 years ago. The annual harvest is doing fine, but the shells are thicker than what is found commercially. Most are nearly impossible to crack ! Can you think of any reason this might be so ? Or is there some soil amendment or pruning advice that might be helpful ? After cleaning I dehydrate them for days in the hopes that making the shells drier will make them more brittle. Not sure if that has been much help. Thanks for any thoughts you might have. Joi

Shell thickness is a genetic trait normally with very little you can do as far as growing practices to change the overall thickness. Commercial almond growers are buying trees that have been bred to have what we refer to a paper shells/thinner shells that are easier to crack. There are varying degrees of shell thicknesses and typically even during the shelling process - varieties are not mixed to ensure a reduced potential for damage to the nuts.
