1、 Nutrient balance

To make the rich greener, we should make its nutrient absorption level more balanced. The nutrient absorption of hydroponic conservation plants is relatively poor than that in soil culture environment. We can add nutrients to it by adding nutrients to the water and applying diluted fertilizer for foliar topdressing

Among the supplementary nutrients, if you want its leaves to be greener and grow stronger, you can slightly increase the level of nitrogen in the fertilizer

2、 Add iron containing agent

Another is that some iron chelating agents can be added to the water, so that the aquatic Fugui bamboo can better absorb iron ions, so that its leaves will become darker and greener
