Pest Watch

Although most pests and diseases are less active in autumn and winter, be vigilant for problems, and deal with them as soon as they’re seen.
Houseplants and plants overwintered in greenhouses and frames are especially susceptible to pests, but can be quickly helped with a pesticide spray.  Maintaining a high humidity around most foliage houseplants – especially those in centrally heated houses – will help keep them strong and healthy and help reduce red spider mite attacks. The reverse is true in greenhouses and frames where high humidity can lead to problems with grey mould and other diseases.
