Q. Hello again!
I have a puzzling issue happening with a few citrus trees
(out of many). The leaves are curling, yellowing, and ultimately
dropping. I attached a few pictures in hopes you could shed some
light on the issue. (Any iron deficiencies you see are from trying to extend
the time between treatments, something I've been trying to perfect; seems like
every 6 weeks is the sweet spot.)
I appreciate any help you can give me, I'd hate to see
these trees die!
Leaf rolling like this on citrus can be a watering problem |

Strangely, the same can result if you are watering too often but it almost never results from giving a tree too much water in a single application. My suggestion to you, if these trees aren't drip emitters, is to make sure that each tree has at least four drip emitters.
Replace these emitters with emitters that double the application rate. In other words, if these are 2 gallon per our email letters, replace them with 4 gallon per hour emitters. This allows you to keep the same number of minutes on your irrigation timer and not overwatering other plants on the same valve.
I would strongly advise you not to use adjustable drip emitters for this purpose. They can be extremely difficult to adjust properly since they seem to act like "whack a mole" when you try to adjust them.
