I took advantage of the warm Spring weather in the last couple of days to clear out the greenhouse. A good wash, sweep and clean still isn't really enough to get rid of any lingering pests which hide in the cracks and crevices. So today I bought a Sulphur Candle
in the garden centre.
I cleaned the greenhouse, then replaced some of the empty pots as they may still hide some pests. Red spider mite
is a tiny little sand coloured insect which gradually sucks the life out of juicy green plants in the greenhouse. My cucumbers have been particularly badly effected. I try to keep the humidity levels high but it just gets worse year after year.
For the past several years my red spider mite
problem has become worse and worse. I have blogged about it in the past here
and have also used biological controls to try to help but I think that poor hygiene and cleaning may also be a factor.
So.. the tin contains sulphur
, with a waxed paper wick. Just light the paper and the sulphur gradually melts to an amber liquid.
Once the wick is lit, the smoke starts to fill the greenhouse. I made a rapid exit as the smell already tickled my throat. I will leave the greenhouse completely shut ovenight then will ventilate thoroughly tomorrow before starting my Spring planting. I hope this helps get rid of these red spider mites for a while.
