A month ago I dug a brand new pond and bog garden. I’ve managed to do this without spending very much money at all:
Pond liner for pond: £18
Liner for bog garden: £10
Water lily: £5
New plants for bog garden: £10
Seeds: £1.99
I also added plants that I already had. The loosestrife I did buy (years ago) but the cowslips, forget-me-nots and irises were all either given to me or came up on their own.
The only thing I was missing was some marginal plants. These are really, really important for wildlife. For this reason, I prefer to use native species. My original plan was to use bogbean but then one morning on Facebook I spotted some of my wildlife-gardening friends talking about using watercress in ponds.
So this is how it’s done:
1. Buy yourself a bag of watercress.
2. Put it in some water on the windowsill and wait.
3. A few days later it should be growing roots. Time to harden it off!
4. Use some aquatic compost and plant your water cress in the pond margins.
5. Done! A haven for pondlife and all for £1.30.
PS I tried planting some in the bog garden. Slugs ate it. I hate those guys.
