What's wrong with my Dicksonia? I planted it several months ago in my front garden in Cornwall. It is positioned in a wind free shady spot whch gets a small amount of morning sun until 10am. I water it at the base and through it's top. The fronds start off looking very healthy and green when they first shoot out however once the fronds get to approx 10-12 inches the ends start to go brown and they eventually die off, never reaching more than 16-17 inches When planted it was planted in a mix of manure and soil to feed it.
What am I doing wrong?
