Hi Susan. There's a nursery on Ebay called Sunshine Gardens. They sell organic citrus, palm and many other fertilizers. I believe most organic types are Espoma, but not 100% certain, so you may already have the type they sell, but it's worth a look-see. Toni

Thanks for the tip, Toni!

You do not mention whether your tree is in a pot or ground.If in a pot,organic ferts ,just down supply enough of the key nutrients citrus need.A slow release fert high in nitrogen at a ratio of 5-1-3(npk) plus trace elements being ideal.In the ground,a balanced fert of 10-10-10 etc would be fine.Feed when new growth appears,especially in spring and autumn.Best not to feed in winter(whats left of the autumn feed should be fine).If your fert feeds for 3-4 months,that would be good.Dont over do the fert,better to be slightly under the recommended amount than over it.Scratch into top soil and water in well.Good luck
