For the past two years I've been burying my plants under a very large pile of dry leaves covered over by a sheet of plastic to keep the leaves dry. I did that today. S. leucophylla 2 plants, S. minor 1 plant, S. psittacina 1 plant, S. flava 3 plants, S. rubra 1 plant, S. Scarlett Belle 1 plant, 4 pots of VFT, a few hardy orchids, a few S. purpurea since I had the room.
I place saucers on about a foot thick of leaves which contain the plants and then fill with rain water or DI. I enclose them in a wire cage and add leaves on top and around. There is about a 2-3 foot layer between the cage and the outside. I then cover the leaves with plastic sheeting and anchor is down with rocks and fence sections. I then put my tomato cages over top to prevent deer from trying to walk over the pile and puncturing the plastic.
