Horticultural aide memoire Control caterpillars
The application of chemicals to control pests on garden crops is a tricky business. We should all keep it to a minimum, not least because we’ll have to consume it. One sound method is to inspect plants carefully, note the arrival of the relevant pest and remove it before numbers rise. This is easy enough with cabbage-white caterpillars at this time of year. One form is readily found under the leaf surface. The other hides ingeniously in the crown. Pick off as many as you can. You can throw the blighters on the path for the robin to despatch.
