How do we control a non- producing almond tree from shedding excessive leaves?
Our 2 trees shed leaves everyday. The trees do not produce any almonds. The trees are 30 feet in height. The leaves have a white fungus and are red with yellow.
Adequate water and fertilization is important to support foliage health, but the white fungus may very well be contributing to the premature leaf drop.
30 foot trees are too big for do it yourself spraying of a fungicide, so you may consider getting an assessment and quote from a tree service with "plant health care" specialist division, like Bartlett Tree Experts.
