I have had my staghorn fern for years now. He has gone through periods of huge growth and periods of near death. Right now he is healthy and happy. He has strong roots and beautiful new growth -- the only problem is this pesky fungus that keeps coming back to his soil. I've changed it once before, but it is back again.
Gross, isn't it? Today I changed out all the soil again, for a nice sterile sandy medium, that hopefully will keep him healthy through the winter slow-growing months. In the spring I will eliminate the soil entirely and get some help mounting him to a wall hanging, where he will grow out of moss and bark, just like he would in nature.
Happy staghorn in fresh new soil.
