Advantages Of Greenhouse Growing
One of the things that makes greenhouse growing pleasant and productive is the ease with which insects can be controlled. Unlike growing in the open, the enclosure of glass or covered plastic greenhouse makes it possible to carry on control measures which are not practical out of doors.
As a matter of fact, there is a short period when the uninitiated possessor of a shiny new greenhouse feels there may be no insects at all, for they are slower to breed in the clean, newly painted greenhouse. But then those little black aphids, mealy bugs and white flies mysteriously appear from nowhere and he timidly attacks the problem with many a misgiving about measures of control. At least, that was my own experience not so long ago and of many others I have learned since. Soon, however, we learn that all insects in the greenhouse can easily he checked with a little attention to details and a few minutes care each week.
Diseases, on the other hand, can present more of a problem once they take hold in the greenhouse than they do in the outdoor garden. Measures can easily be taken, however, to prevent them from getting that start.
Another thing we learn early is that it doesn’t take a whole array of expensive insecticides and fungicides to do a good job in the greenhouse. The same ones as used in the outdoor garden, plus one or two fumigants and perhaps an additional spray material or so, are all that are needed.
Aphids, thrips and green fly, the most common insects we meet, are easily controlled with malathion. There are, however, a few tips and cautions applicable to any pesticide chemical use in the small greenhouse which may be in order.
For instance, spraying should never be done when the sun is shining brightly or if the greenhouse is dry. It is best carried on early in the morning or late in the dy.
Naturally, spraying and fumigation can be overdone, and should be used only when needed. At best, they do not help plant growth, and so spraying or fumigating just as a precautionary measure is not always advisable.
In most greenhouse, fumigation methods cannot be used, sprays and dusts will prove almost as effective, though more frequent applications may be needed. Red spider mite can be kept in check by syringing with water under pressure and continual applications of malathion. For scale, which attaches itself to the stems and leaves of cacti, succulents and ivies, use malathion as well with soap as a spreader.
