a) keep the mulch light (four inches or less), loose and clean;
remove all old or fallen plant parts and weeds from the greenhouse.
b) do not over water, especially in the winter when the greenhouse
is closed, uses less water, and has a higher humidity.
c) pull up plants past their prime.
d) watch plants that are in poor health and pull them up if they donít
recover after a couple of foliar and soap sprays and continue to fail
to grow as well as neighboring plants of the same type or variety.
e) do not put diseased plants in the compost.
f) keep the air moving with both ventilation fan(s) as well as circulating
fan(s)-this also keeps air from stratifying.
g) intercrop and rotate crops; monoculture in the greenhouse is unwise
h) keep good records and donít be afraid to try different and unusual
varieties. Experimenting is fun. When I planted seven different heritage
varieties of pole beans they turned out widely divergent in their growing
habitats, health, insect resistance, and productivity. Find out what
works for you.
i) buy a good organic gardening greenhouse growing book with a section
on pest identification and control. Try the trapping, baiting, use of
predators and beneficials, vacuuming and repellant sprays they recommend.
I did and the suggestions do work!
