BETTER ANSWER:
A newly planted tree has no "deep roots." The roots are all in the
original rootball. Usually, the tree comes with looser soil than the
transplant site, so it dries out quicker. For the first few weeks,
standing by the tree and spraying it is exactly what you should do,
and you should do it often. Once the tree begins to spread new roots
into the native soil, you should start thinking about deeper
water--but I prefer a nice, slow soaking to the method above. Tree
roots exist primarily in the top couple of feet of soil. A deep-root
wand will put most of the water below the tree roots.

Most of the non-woody, absorbing roots (roots that absorb water and elements
dissolved in it) are mostly in the upper four inches of the soil. As the
tree becomes established, the non-woody roots will still be in the upper 4".
You should water the root ball area well at least two times. Then water
should also be applied further away from the root ball.

I agree with Keith Babberney. For the record, my father planted a blue
spruce, maybe 30 years ago. As long as I can remember, the tree had bag
worms. The bag worms have not killed the symplast of the branches and the
tree still looks fine. Thus removing the branches with bagworms would be
like placing a tourniquet around your neck to stop a nose bleed. Back to
pruning. The biggest problem for trees and branches is improper pruning. A
must to read is this book.

with many of the tree problems we face in our cities. Wound dressing adds
insult to injury. We must also care for the system and not just the wound.

Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us
that we are not the boss.
Some people will buy products they do not understand and not buy books that
will give them understanding.




As for fertilizer, it is irresponsible to recommend any regimen that
does not start with a soil test.

But virtually every tree will benefit from a properly-installed layer
of organic mulch (see link below for instructions).

QUESTION: Several years ago I bought 25 hybrid poplar. Within 1 and
1/2 years they grew 15 ft tall and were just beautiful, but this year
they got holes going in a circle half way up looking like a woodpecker
had got at them. They leaved out beautifully half way up the tree,
however the rest of the buds on the tree did not open although they are
not dead. We put some kind of
tree paint from our nursery that was black and the holes (which I think
are due to some kind of borer) have stopped moving up.

My question is what do we do with the 5ft of bare tree in the middle?
Do we cut it or leave for the tree to recover... or will it? Any help
you can give us would be appreciated as we do not want to lose our
beautiful trees as they line our 4 acre property. We live up in the
middle of the mountains and people always stop to admire our trees. -

ANSWER: Don't despair! This should be fairly simple. You need to cut
out the dead section
down to the green wood. Once the dead is removed the tree will start a
process of putting on more top growth. Send a picture through email if
you can.
BETTER ANSWER:
If you want to determine what parts of the tree will survive, use the
thumbnail test. Scrape the bark of a suspect twig with your nail. If
you reveal green tissue under the surface, the twig is alive. If it
is dry and brown, it won't come back. Prune it to a branch collar
(see link below). Do not paint the wounds.

The holes are most likely from sapsuckers (bird family that includes
woodpeckers). They bore a series of holes, which exude sap. They
come back later to dine on the insects that are stuck in the sap.
Your treatment probably made their diner look less appealing, so they
moved on.

QUESTION: "What is the best what to rid my trees of bagworms?" -
John D

ANSWER: The first thing you have to do when you see them is to clip
them off the branches, put in a bag and take them somewhere to burn
them. Afterwards you need to spray the plants with an insecticide, such
as Monterey Garden Insect Spray, about once every 30 to 45 days.
Usually, you'll only need to do this two times per growing season.
Follow the direction on the bottle to make sure your particular plants
are okay with the chemical.
BETTER ANSWER:
Avoid poison controls. Spraying a tree means lots of overspray in
most cases. The simplest solution is to use a pole of some kind to
poke holes in the webs. If possible, roll the webs onto the pole like
spaghetti onto a fork. Once the protective webs are gone, the natural
predators (insects and wasps) can access the worms and kill them. The
denuded branches are rarely killed by defoliation--leave them alone,
and next year (or later this year) they will probably come back.

If you are seeing a particularly bad outbreak, you can control with Bt
(Bacillus thuringiensis), which is sprayed onto the leaves. When
ingested by the worms, the bacteria kill them. This treatment kills
caterpillars indiscriminately--i.e., not only the bagworms, but other
moth and butterfly larvae may be affected. Spray as a last resort.
