Insects need places to shelter from harsh weather and also to hibernate. Insects are also an important food source for various birds, like robins and blue tits.

Leave a Log

This is one of the simplest things you can do to help the insects:

Just leave a log in your garden!

Any log will do, but wood from a native tree is best.
Perhaps you have a wood burning stove and are willing to leave one log in your garden, or maybe you know someone who has logs (always ask first!). You can also take a small log or branch from a forest, but make sure that it is only one and that you don't disturb any wildlife.

By the way, mushrooms will also grow on logs after a while, which is very interesting and logs provide structure in your winter garden when all herbaceous plants have died down.
