I bought a Dicksonia Antarctica in a pot of about 30cm diameter in late April. When I bought it, it had a few baby fronds emerging but these have since disappeared with the exception of one which hasn’t really grown beyond 4 inches and is brown at the edges. I have kept in the pot so far and am doing everything I am supposed to by keeping it moist and in semi-shade. It was an expensive birthday present so I don’t want to lose it!
