Normally around a rec pond there's clay under the dirt to make a water tight
seal and to stop water movement into the surrounding area. You might want to
pull the liner through the dirt at the top and put rocks on the top of the
liner to conceal. This would seperate the pond dirt from the earthen dirt.

I have installed a new wildlife pond, about 4m x 6m. I have banked soil
right the way into the pond as per most instructions for wildlife friendly
ponds and it all looks good.

However the way is now draining out of the pond due to capillary action
(or
wicking, as it is sometimes called). Although I have a lovely area of wet
soil all around my pond, I was hoping to keep some water inside the pond!

Any idea on how to cut down this effect?

Can I do something different with the liner to help prevent this? At the
moment I have this:

*****************soil
water * * ------pond liner
***** /
pond liner------- earth

Any ideas?
