How to use sedum mat for pond edging – It’s difficult to find plants to use around the edge of a pond. Particularly if you want them to hide the pond liner and attract wildlife. Ideally, we also want to refrain from dropping seeds, leaves and debris into the water and look lovely all year round with the minimum of attention.
Provided the pond in question is in a sunny spot, sedum matting fulfils all of those criteria.
My lovely Brother (who my children call “Auntie Dave”) put a little pond in for me as a Christmas present one year. It’s beautiful, tucked around the corner from the summerhouse. It has a little fountain and some twinkly lights. It’s also home to two frogs and a myriad of insects. It gets visited by blackbirds, sparrows, blue tits et al. I love it.
However, the landscaping fell to me. There I was with a hole full of water edged by a 60cm width of butyl pond liner. I couldn’t cut it or remove it – because then the pond would collapse – and it’s in such a place that it would have been difficult to lay paving around it. This presents a real conundrum.
Then I remembered sedum matting. It’s normally thought of as green roofing material, but actually adapts well to being used on the ground. The plants already have as much growing medium as they need. There’s no need to dig a hole or add extra soil. But It does need to be installed properly – as if it was on a roof but the low-growing plants are adored by butterflies and bees and they don’t drop leaves all over the place.
Going to the extra expense of buying drainage mat and water retention along with the sedum matting seemed a bit daft, but actually it was a worthwhile investment.
If sedum mats are laid directly on the soil, any seeds that are dropped on to it by visiting wildlife can happily germinate and put their roots down into the earth for a ready supply of food and water.
When the weeds are denied access to soil, a long dry summer will kill them off naturally. Sedum plants on the other hand will normally survive a drought without too much fuss.
How to install Sedum matting on the ground
Lightly rake the soil and remove all sticks, stones and debris.
Cover the area with heavy gauge polyethene or butyl pond liner.
Unroll a layer of drainage matting on to the poly. This will prevent the plants becoming waterlogged.
Lay water retention matting on top of the drainage mat….all of these mats can be trimmed with scissors or a sharp knife, but take care not to damage the polyethene.
Your Enviromat sedum matting is the last layer to be installed. It sits on top of the water retention matting.
Give everything a good soaking to settle it in and BINGO! Your pond is surrounded by a carpet of plants.
Sounds too good to be true? Believe me, it really does work!
