Pest control Watch out for pests.
Treat immediately with conventional pesticides, or consider using biological control agents for the control of whitefly, red spider mite and other pests. Most biological controls are very sensitive to pesticides, so do not use any sprays on plants if you are considering using them. At this time of year some plants, like fuchsias, benefit from pinching, removing the very tip of a shoot to encourage branching. Check plants regularly as their demand for water increases, most will also benefit from weekly liquid feeds. If plants are becoming pot-bound, move into bigger containers.
