Can I save my waterlogged garden?

Waterlogged Garden

One of the stormiest winters on record has caused widespread wind damage and waterlogging in areas that are susceptible to flooding.


Once the water has dispersed, most garden plants will die due to a lack of oxygen in the wet soil. However, the good news is that once the stormy weather has passed, there is still time to repair some of the damage, so you can enjoy your garden this summer.

The Royal Horticultural Society has shared the following advice for those affected by waterlogging:

  • After flooding, wash down any hard surfaces and collect debris to prevent drain blockage and pollutants or contaminants lingering in the garden.
  • Keep off the soil until it is workable. Avoid compacting it, as this will only make the conditions much worse.
  • Damaged shoots should be removed from plants.
  • Do not eat edible crops that are near to harvest. The root crops could be contaminated and will not be safe to eat. It is recommended that you avoid growing salads or other uncooked crops for two years to prevent disease, as spores can remain in the soil. However, you can begin to grow crops that are to be cooked the following year after flooding has occurred.
  • Apply a balanced fertiliser in the spring and mulch over the root area to encourage new growth.
  • Thoroughly water your garden during dry spells after flooding, as plants will be more susceptible to drought stress.

If you live in an area that is susceptible to regular flooding, there are plenty of long-term options to improve your soil drainage. Keep an eye on our blog for more information about soil structure and cultivation in the coming weeks.
