I moved 2 very substantial basic ferns in big pots to under my oak tree, replacing 2 smaller new basic ferns I bought a month ago, which did fine there, but were too small looking, so I swopped them with bigger ones I had, on Tuesday last week. (Small ferns were healthily growing under the oak).
Today I noticed one of these big ferns is turning brown, the other is limp!!! So I have quickly rescued them. But I dont want to swop the small ferns back, I am successfully using them elsewhere now..
Will 'Acanthus Molis' grow under oak trees & in pots? I am in Surrey. HELP! Or what other will give me good large cover under the oak? Grateful for all info anyone can help me with re the above? And all suggestions! Thankyou kindly -
