Citrus as a group includes oranges, lemons, mandarins and tangerines. In the UK they are usually grown in containers in the greenhouse or conservatory. Citrus are long lived plants and may occupy the same pot for many years. The high levels of humic and fulvic acids in Citrus Focus are designed to increase and maintain soil fertility in pots and containers over long periods.
