Last September I spotted a 4ft. Dicksonia Antarctica in my local B & Q standing in a pot, without any frongs. The garden manager told me, it was the last of a bunch that had all been sold. In his opinion it had died and would be shortly thrown out. He assured me the tree had been healthy with plenty of leaves, but they had died back. From this I thought maybe lack of water (I have seen the staff squirt the hosepipe around and some plants get it and some don't) So I took a chance at a low price, planted it in my garden and continually sprayed it until winter, when I covered the crown with sawdust and bubblewrap. I took off the 'cap' in spring and continued with the water spraying when it was dry. So far nothing (2nd. june) Any suggestions please.
