We stripped it off earlier this year and sowed some Medallion lawn seed, available from Rolawn Ltd. It looked very nice but needed something on top. I favoured a hololith but they're expensive. So being the recyclers that we are, we decided to build a folly from a pollarded willow. We'd already created a new willow tree and a willow arch from it, so why not a folly? After a very hot morning digging deep holes to bury the willow in and tying it together, we were pleased with the result. It will take several months to know if it has worked but should be worth the wait and will be a lovely picnic spot. Or it may be complete and utter folly! What's gardening without experimentation.
