Winter is a good time to clean, tidy and reorganise your greenhouse, while it is relatively empty and there are fewer jobs in the garden to take up your time. Cleaning the greenhouse will maximise light levels, clear blocked guttering, banish any pests and diseases. Tidying it will make sure that you have an ordered working environment in time for the growing season ahead.

Get our advice on the essential kit for your greenhouse.

Choose a mild day so that any overwintering plants can be safely placed outside for a while.

If you're overwintering tender plants, choose a mild spell to empty your greenhouse completely. Cover plants or take them into the house, if necessary. Brush down framework and staging, then sweep the floor.

Once everything is outside promise yourself not to return anything that isn't absolutely essential.

Both the inside and outside of your greenhouse panes will need cleaning. Take a bucket and sponge and long handled sponge, thoroughly wiping over every pane with a solution of glass cleaner to soak and scrub off dirt. Use a stable platform or stepladder to reach the glass in high ridges.

Winter is a good time to clean, tidy and reorganise your greenhouse, while it is relatively empty and there are fewer jobs in the garden to take up your time. 

Check your gutters for collected leaves and debris, which could filter down into water butts. Brush out the rubbish before it flows into the downpipes. If the guttering needs replacing, read our guide to fixing guttering to a greenhouse.

Empty out water butts and clean out any accumulated dirt in the bottom, then put them back into place. Find out why you should empty your water butt from time to time in our Quick Tips guide. If you don't have a water butt, now is a good time to install one - it will mean that you have a handy water source on hot days.

Wipe down surfaces with scouring sponge and wash flower pots and seed trays with disinfectant before thoroughly rinsing. Return everything outside to its proper place in the greenhouse.
