Is cabbage hard to grow?
Zone 6B
No, the only problem I've had is with cabbage moth worms. They will
wipe out a plant in days. Fortunately, Bt will solve the problem
with regular applications.
what is Bt?
Â*Â*Â*Â*Â*Â*Â*Â*Â* Bt is a biological agent (not a chemical poison) that is
widely
used in "organic" gardens.
Â*Â*Â*Â*Bt {Bacilllus thuringiensis (k)} is an organism that when eaten by
them kills ANY lepidotera—even the pretty ones—in its soft body instar
(caterpillars and "worms") by stopping its digestive system from
working.Â* Widely available in a liquid concentrate and in a powder.
Â*Â*Â*Â*Bt (i)) is effective exclusively on most mosquito species and is
generally available as bouyant "dunks", which may be floated on standing
water to eliminate larvae, and is less widely available in a granular
form.
Â*Â*Â*Â*Bt is highly selective, short lived, and affects only a very small
universe of crawlies.Â* It is harmless to other insects, including ants,
wasps and bees, to reptiles and to mammals.
Fascinating!
They got one for squash bugs?
Â* No , but diatomaceous earth works well on them . Kinda like rolling
in a bag full of razor blades to an insect with a waxy carapace , the
sharp edges abrade the waxy coating and they dry to death .
