I am hoping to get some advice. I bought four windmill palms in the heat wave and the cold bc winter. They went through our winter still being green but now they are turning brown throughout. THe ones in our neighbourhood seem very healthy. It appears that only ours were affected. They were newly planted. I went back to southwest nursery where they have said they are not sure but maybe applying a fertilizer could help. I am trying to find some advice on what to do? Do I fertilize this early in spring, the fronds seem like they are not budding on a few and are stiff however is this normal? I don’t want to fertilize and burn the roots and I don’t know who to ask for advice.
