How much stress can an almond tree take without irrigation?

Growing almonds requires a lot of water, a resource heavily regulated in some areas.

It led researchers at UC Davis to roll up their sleeves and see just how much stress an almond tree can take.

“We had two sites, we have six years in one and three years in another, and found that we could wait a substantial amount of time, more than one month after growers normally start irrigating. We have not seen any bad effects on yields, but we have seen a better tree appearance in the trees. Now, we haven’t actually seen any serious symptoms, but at least delaying irrigation for long times has had no detrimental effect and some positive effects,” said Ken Shackel.

No worries there, but starting irrigation too late can cause issues. Shackel calls it the “bank account effect,” when the trees take up too much water too quickly, and then do not have enough to get through harvest.
