4. Clean your gardening tools
As they say, cleanliness is next to godliness, so make sure your gardening tools are in tip-top shape. Just like your greenhouse, they may also carry bugs or diseases, so give them a good scrub as well to ensure they don’t have a chance to infect your plants.
5. Remove any unwanted pests
This is not a euphemism; get rid of any hibernating pests such as aphids, slugs, and snails now so that they don’t even have the opportunity to get at your plants. One bug to look for in particular is the white vine weevil larvae (not pictured, simply because they are just too gruesome-looking). They live in the compost and will, without a doubt, feed on plant roots.
