FUMIGATING

A reader asks about fumigating his new greenhouse after its first season, and I can only' suggest that he buys one of the proprietary fumigators designed to burn or vaporise, taking care, when doing the job, to see that insect-harbouring things like tiles, slates, flowerpots and seed boxes-are' removed from the hoUse and cleansed before they are brought in again.
