Now’s the perfect time to give your GREENHOUSE a good clean, ready for the seedlings and cuttings of spring. Wash the outside of your greenhouse with disinfectant or detergent, to remove algae, moss and general grime. This will let in more light during the growing months, while removing potential homes for pests and disease. Make sure you disinfect the inside of the glass too - overwintering pests and disease can survive in the smallest nooks and crannies.

Sweep out any plant debris on the floor and benches, and wash with a hot solution of garden disinfectant such as Jeyes Fluid. While you're there, wash pots and seed trays to help prevent diseases like 'damping off' from infecting your young plants. Ventilate your greenhouse well over the next couple of days so it dries thoroughly.

Once your greenhouse is clean and shiny, take time to inspect the structure for any damage to glass or vents and replace any broken parts.
