[Arid_gardener] Dying Sisso Trees

[Linda Drew]

Hi, Angela


Make sure you are weatering the trees to a depth of
3 feet and out to the dripline.

It is possible the trees have a fungal disease such as
cotton (Texas) root rot. Do the bbrown leaves stay
on the tree or dffall off? You can take a sample of
pencil-sized roots, seal in a plastic bag and take to your
nearest cooperative extension office to check for this.
