Beware of so-called tree experts who do not understand tree biology.
Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us
that we are not the boss.

I've started using mulch around the base of all my fruit trees this year,
I live in a hot summer area and I'm trying to
keep the roots as cool as possible (not to mention the other benefits of
mulch), but since I have some trees that will
grow in the winter time (mainly citrus) I wonder if pulling back(only for
the winter months) the mulch would help warm
up the ground beneath them and they might benefit more from this than from
the mulch. These are young dwarf citrus
trees I'm speaking of. The mulch is about 2-3 inches thick and I'm
planning on adding to it next spring.
