Cleaning your greenhouse will help your plants to grow and remain healthy, as by cleaning your greenhouse you are reducing the risk of pests and diseases. It’s good to clean your greenhouse twice a year – once in the autumn when your greenhouse is likely to be less crowded and early spring before you start your sowing your spring seeds. You should clean your greenhouse glass – outside and in – to remove any build up of dirt, algae or moss. This will ensure maximum light can reach your plants – important during the autumn months when light levels are lower. It’s also important to clean all the surfaces in your greenhouse – wiping clean shelf and bench surfaces. You also need to clean empty pots, seed trays and covers – wash them in a mild detergent and clean thoroughly around the rim of pots where pests and disease can harbour. It’s also important to wash the gravel covering your benches, water matting or capillary matting, to prevent the build up of algae.
