I recently bought 2 phoenix canariensis palms. They both were health with leaves all green. I have repotted them into larger pots and the leaves are turning brown as though they are dying. I don't know if the pots are to large for the palms ? I had two palms last year to and they both went the same way and died. So replaced with these ones this year as they said they are hardy ones and easy to keep. Would be greatful if any one can point me in the right direction and help me save the palms if not to late.
