An ORGANIC Fertilizer
Potted citrus or any other potted tree needs your help to produce food ...thus you should add an organic nutrient rich "fertilizer" such as a humic concentrate. You can use synthetic NPK "miracle grow" or tree spikes to fertilize but they are not as safe or as effective as an organic one. We sell one type of fertilizer......enough to do a lot of plants...both indoor or outdoor.
