Wet Soils & Clay Grass Seed



Grass seed for clay soils that often sit wet or suffer from occasional flooding. Sometimes a wet lawn is unavoidable, especially on a clay soil, so it makes perfect sense to select a grass seed mixture that will tolerate wet soil conditions.

Heavy clay soils are often saturated in the winter, but can rapidly turn bone dry in the summer. Our Wet Soils Grass Seed contains tall fescue which is deep rooted and extremely tolerant of this type of soil condition.


  • 40% Perennial ryegrass
  • 40% Tall fescue
  • 20% Strong creeping red fescue

Thank you for the grass seed, with all the rain I have had I can see it’s back to a swamp, maybe I need stronger grass seed but Thank you

Hi Jacqueline,

It has certainly been a struggle this autumn with all the wet weather. It is true that grass seed needs moisture to germinate and establish well, but if the ground gets saturated you can run into establishment problems. Once up and established the grasses within the mix will tolerate extended periods of waterlogging. But please do drop us a message and send some photos to and we will be glad to help further.

Kind regards,
