Patrick gave me a 2 leaf seedling of trachycarpus princeps 4 years ago for a house warming present. I grew it up to a beautiful 5 gallon plant with tropical looking fan leaves and very silver undersides. I planted it out last Summer and it was looking good. Sometime over Winter it started not to look so hot. The leaves were appearing to sunburn and browntip, even though I knew this species loves the sun, and it stopped growing. I hit it wit some fungicide but it's leaves continued to brown,
