Greenhouse cleanliness is a must; old potting soil should never be reused as it can introduce pests into the greenhouse.
Dead plant materials should be removed immediately from the greenhouse.
Pots should never be reused without thorough cleaning. Sterilization is crucial to keeping plants free from pests. A thorough soaking for 10 minutes in a solution of nine parts water to one part bleach, followed by a good scrub, will clean most pots. Mineral deposits remaining on clay pots can also be removed with a commercial solution such as CLR.
