My lawn is very wet for most of the year. I want to install a small patio, raised beds and cover quite a lot of the garden with stone chippings. My question is will I have a problem with algae on the stones if the water does not drain away sufficiently? I have looked into drainage solutions but have been told the mains drain is too high to create enough of an incline. I don't think a soak away would work as when I had a new fence put along the bottom of my garden the workman had to use a pump to keep the water out of the holes to allow the concrete to set.



Sounds like a plumbing issue. Look into getting the drain refitted. Algae on the stones? Structural damage to the house? Wood rot? Black mold? All are possibilities.

Hi Kitty! Yes, pebbles and gravel do get algae. Is this a north facing site? A photo would be great, we would be able to see what your plans are in relation to what you have. :) But you wont solve this problem by covering it up.

I would retain part of it and have a bog garden - there are some very nice things that would grow there (sorry I know this isn't what you asked...)
