EARLY
KILLERS: Prevent Mold and Mildew - Root Rot - "Damping Off"
When I brought my artichoke plants into
my greenhouse
last November, I did not take
into account that they could not handle the increased humidity. I ended up
losing about a dozen plants. With the increased damp air, I also
experienced an infestation of gnats! And, because there were no
predators, cut worm moths came and finished off the few healthy plants I had
left.
The same can
happen in the beginning stages
of growing seedlings. In Alaska it is called "damping off." This
happens when seedlings rot away before or soon after they emerge from the
soil. Moisture is important for plant growth, but if garden plants and
house plants are not allowed to dry between watering they will become
subject to fungus infection. Because Alaska is a damp environment,
there are problems with fungus growth - especially if plants are
transplanted outside too early in the season. When infected, plants will
often rot at the base of the stem, leaves can curl, wilt, and brown, and
roots can turn black or turn to a mushy consistency. Poorly drained planters
are one cause for the problem and can be prevented by laying down a layer of gravel at the
bottom of a planter box under the soil. There are fungicides for
damping off, but by the time it is discovered it is often too late.
Pull the dead plants. Toss them in the compost pile and start over
again.
