I have built more than 2 bog gardens as I love the plants within them so much. For each one I removed about 60cm of soil, layed an old butyl liner in the bottem in which I pierced quite a lot of holes, and a length of hose with pin holes in it that layed along the bottom in the middle of the liner, with the top of it coming out hust above level ground which i attched a hose end to so that I could water the trench at the bottom with a hose. I then tipped in about 3cm of gravel into the bottom then refilled all the soil back in. I planted it with astilbe, ligularia przewalskii, hosta's and candelabra primulas. I another nog garden I have which is built almost in the same way except it is fed by a stream which is topped up by the water off of my roof via a wheel I have I have planted atstible, drum stick primulas, gunnera magellanica (a tiny gunnara which is fully hardy), ferns, iris ensata. golden sedges, hostas and delmera peltata.
