Hi,
I purchased a healthy Dicksonia Fibrosa in the autumn and after reading threads fortunately put in an outhouse and wrapped for the v cold winter. It is still in tub and I lifted it outside last week and unwrapped to find all 10 fronds are browning and have still not unfurled. I've also noticed some white powder on the leaves - is this some form of fungi?
I only sprayed the fern a couple of times during winter, should i have watered more? Do i remove the fronds and should I plant in suitable place to prosper (I've read they do indeed have roots)? I'm very concerned I've terminally damaged a great tree fern..
