are some helpful fall gardening tips from one of the
now. Fall is the ideal time to plant new trees, shrubs
and perennials or transplant existing plant material
because the weather is cooler, roots continue to grow
and there is no worry about soil drying out quickly.
Fall planting allows carbohydrates produced during the
previous growing season to go to important root growth
because there is little food demand for the plantís
properly. Dig a hole a foot wider than the circumference
of the root ball and the same depth as the root ball. If
the plant is coming out of a pot, take your fingers and
try to loosen some of the roots so they will continue to
grow outward instead of in a circle the shape of the
pot. Set it out in the middle of the hole. All plants
are coming from the nursery now planted in mulch rather
than soil. It is best to remove as much of that as you
can because it will dry out the roots faster. Then
continue to back fill with the soil you just dug out. We
no longer recommend adding additives to the soil unless
you have really bad hard clay soil. It is also good to
make a two- or three-inch collar of soil around the
roots to hold water. Water slowly and well to get rid of
any air pockets in the soil and to settle the soil
around the roots. Then apply two to three inches of
mulch, making sure that you do not push the mulch up
around the stems.
Seen particularly on junipers, yews and Leyland cypress,

blight. This bacterial disease, which creates a
blackened, shrunken, cracked or scorched by fire look,
should be cut out as soon as you see it. Make a cut
eight to 12 inches back into good wood and put it into a
plastic bag and dispose of it in the trash. You also
need to sterilize loppers so you donít spread the
disease to other susceptible plants.
insects. Bugs that colonize and may come in your house

brown marmorated stinkbugs ó can be a nuisance but
cause no harm to your house. They will not eat anything

then dispose of the vacuum bag. Do not try to squash
them because they smell terrible and cause a mess.
