It depends on exactly what's where...and there are several methods. All of the following are done a bit above the waterline, but careful that the attaching method be level so it looks better if it's to be visible. I use a water level for this. For flat areas I drill a hole into/thru the concrete and then using masonry screws I screw a board to the concrete. For even an 8' length 2 screws are plenty. The board is parallel with the waterline. I nail the liner to the board using 1/2" roofing nails. The nails have to be above the waterline. I prefer to nail down into the top of the board rather than into the side. The type of board can vary. Plain wood, pressure treated or my fav plastic deck material. I rip down the decking to about 1"x1". Sometimes I use a full wood 2x4 pressure treated. For curves I use bender board, again I prefer plastic but wood is fine. I rip down the plastic bender board to a 1-2" width. I put on 2 or 3 ply (layers) and the when nailing the nail just goes between the plys when nailed from the top and I use a 3/4" nail then. Nailing from the side requires more plys so I don't see the point of that. I like using concrete screws because they last and are easier than epoxy. But epoxy can be used. For epoxy you have to brace the piece while the epoxy cures which is a pain. A combination does work well, a few screws where you can and then epoxy any loose places and the screws hold the board in place. You can also push a bit of cloth into gaps to keep the epoxy from flowing down and out the bottom. You can also cover a bit of cloth in epoxy and shove that into gaps. It does not require a strong structure. The weight of the water will push the liner against the concrete and nail it into place, you can't move it pulling as hard as you like. The only thing that's needed is to stop the loose liner above the water from flopping over into the pond. There isn't a great glue for attaching EPDM to concrete. It just doesn't last very long. Depending on the rock at the top I'd bust them out, lay the liner and then mortar the rocks back into place. I normally mortar over the liner, or mortar rock over the liner. In this case the mortar can be enough to stop the liner from flopping over. However, I prefer attaching a plastic board, nailing the liner and then mortaring over it all. I think that lasts longer and is easier to do even though it may sound harder. In all cases I don't nail liner until after the pond is full. This requires the liner to be larger than needed, but that's normally not a problem.

I took a different tack -- last summer I deliberately planted a 6" double row of groundcover plants at the base of my curved knee-height walls (made of stacked slabs of broken concrete) -- ajuga in the shady areas, and violets in the sun. Both made nice low lines of dark green to contrast with the pale-grey concrete, smother (other) weeds, don't need weedwhacking, and don't take any harm if the lawnmower runs over their edges. And they bloom, too. These plantings are now a year old; the ajuga is less thick than the violets so I've had some trouble with dandelions there (this was a very dry summer) but neither are doing much (yet) to invade either the lawn or the beds above the wall. I'll let you know in another year or so how it looks longterm, but so far it's cut my workload considerably... FWIW. LynnT

No deer here, thank goodness. I don't know how anyone manages to garden with those darn things. The new stone wall goes with other things around here, I have various stone walls here of different types but I really love the way this one turned out. Honestly, I can't tell the difference between this covered one and the real thing out in the front yard. I am really glad I saw the display when I was at the place looking at pavers for the front steps. It sure looks a thousand times better than the cinder block wall that used to be there. One of my better ideas. I just never liked the cinder blocks in the backround of my daylily pictures. Going to like this much better :-))

Melanie - PLEASE tell us what you made those markers out of! I have made a few from the clay you bake but it is a little pricey. Karen - WOW WOW WOW!! I got my box yesterday and I love what you sent : ) Iris: From a Distance & Thornbird, Daylilys: Kindly Light & Little Joe, White tiger Lillies. These are not tiny puny little starts - they are HUGE, very mature plants! And then lots of seeds! Annuals and perenials and wild flowers. These are wonderful as I have 39+ acres to cover and I have been collecting wild flower seeds everywhere I have been this summer - my neighbor 'Steve' is rather shy (we have been neighbors for over 6 years and he has only been to my house once - my cows were out) & I even have him leaving little bags of seeds on my step LOL I don't think he cares so much for collecting seeds, he just would like something better to look at besides the over grown weed patch that it is now. hehehehe Also - my cleaning lady 'cleaned' off my desk and I can not find my sheets of paper that the names of those Iris that I sent you are on. All the bills and junk mail that were cluttering it up are present, though! :( I don't think they are gone forever, just MIA for awhile... but when they turn up I WILL get them to you. I hope everyone had as good of a weekend as I did! I caught & released fish, took pictures and saw my eye doctor. My vistion is 20/20 and everything is healing wonderfully! Life is good : ) Marie
