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 only one type of fertilizer …. a blend of slow release pellets and humic concentrate
Enough concentrate to do 10 or more potted plants and several dozen outdoor plants. One application is enough for one year
Humic Slow Release Concentrate .....$39
