One of the most challenging jobs to do in a greenhouse at this time of year is to keep the temperature down. A lot of summer plants will grow far too quickly in the excessive heat and you will be left with straggly, tender plants that will be severely checked back when they are put outside. I remember one time I planted a large amount of petunias in the tunnel and left them a week too long in the hot weather and they were ruined. If the plants cannot be taken outside into the cooler areas then shade netting could be put up or the structure of the greenhouse can be painted white to reflect the heat.

Feed containerised plants. Most composts only contain sufficient nutrients to feed plants for about four to six weeks after potting up. Potted plants will then benefit from a weekly liquid feed to promote strong growth and generous flowering and fruiting.
