Adding coarse grit can help to improve drainage, especially in winter, when most plants hate sitting in cold, wet soil. It’s also a good idea to add grit to the bottom of the planting hole when adding new plants.

If you have very wet soil, consider creating raised beds, both for flowering plants and for veg – you can fill these with the perfect soil mix for the plants you would like to grow. Alternatively, plant onto mounds of soil so that excess water can drain away.


Protect plants from slugs and snails

Slugs and snails thrive in damp conditions, where they wreak havoc on young plants and vulnerable plants such as hostas. Scatter slug pellets sparingly – organic ones have been found to be just as effective as chemical ones and are less harmful to wildlife. Find out how to control slugs and snails organically.

Heavy rain can compact the soil, creating a ‘pan’ on top. To avoid this happening, fork over the soil lightly – this will help the rain to drain into the soil, rather than sitting on the top.


Avoid treading on the soil

Avoid walking on the soil if it is wet after rain. If you need to dig or plant, work from a plank to avoid compacting the soil further.


Install a drainage system

If the soil is waterlogged, rather than just damp, you’ll need to install a ground drainage system.
