If you have a grubby greenhouse give it a good spring clean before you need to start seed sowing in earnest!
Citrox is a natural garden disinfectant that can be safely used on all your greenhouse surfaces including pots, capillary matting, staging, tools and accessories. It is effective against a wide range of bacterial and fungal diseases.
Try to get in all the nooks and crannies where over-wintering pests might be lurking. Give the glass a good clean to remove dirt and algae and maximise the available light to your plants and seedlings.
A diluted solution of Citrox can be used to wash bulbs, corms and tubers and it is effective on pond accessories and bird tables too. It
can even be added to water butts to keep water sweet and free from disease.
