Healthy, thriving trees are a real
source of beauty in the Kyrene
Corridor’s neighborhoods. But last
month’s freezing temperatures – the
lowest since 1990 – caused something of
a “brown out” for the area’s trees.
According to certified arborist Joe
Mancino, whose Tempe-based business
is called Tree M.D., it’s alright to
trim frost-damaged trees now “because
we’re pretty much over the hard cold.”
But should there be another freezing
night before spring officially begins,
he advises homeowners to leave part of
the south-facing sides of smaller trees
uncovered so the air under protective
coverings stays warmer.
Here are some tips Mancino offered for
cleaning up frost damage:
Find where the dead wood meets the green
wood on tree branches and trim about an
inch into the green part.
Citrus trees can be fertilized now.
Hold off on fertilizing other types of
trees in your yard until after they
blossom in the spring, and choose a
fertilizer that contains potassium
Don’t forget to water trees sparingly
during these cooler months of the year.
