Feed tomato crops with a high-potash tomato fertiliser every week
Be on the lookout for aphids, vine weevils and other pests
Ventilate daily and add extra shading if temperatures are getting too high
Sow primulas, calceolaria, cineraria and cyclamen
Pinch out sideshoots on tomatoes
Pot up houseplants that have become top heavy or pot bound
Take leaf cuttings from houseplants including Begonia rex, African violets, streptocarpus, crassula and kalanchoe
Pick peppers, tomatoes, cucumbers and other greenhouse crops regularly to encourage further flowers to develop
