If liquid fertilizer is applied, especially when the weather is hot, it is necessary to dilute the backwater. when the fertilizer is decomposed, it may produce ammonia, which is corrosive to Langen when it accumulates in the basin soil. But the solid slow-release fertilizer is not necessary, just let the orchid basin soil slowly melt it. To a certain extent, backwater will wash away fertilizer, which is also a waste.
