Near Atlanta, I planted a 4 foot windmill palm 3 yrs ago and it really thrived for the first 2 years. Last year I placed a potted grapefruit tree near it and they both almost died. The palm stopped growing and the grapefruit tree's leaves got very yellow. When I realized this, I separated them. The grapefruit tree seems better (took it inside for the winter) but the palm shows no sign of new growth for about a year now. The fronds are still green but droopy. It still looks alive. 1) is there any known compatibility issue with Windmill palms and Grapefruit trees? 2) is there any hope at all for this palm?
