Weak stems in my Water Sprite
My water sprite (Ceratopteris thalictroides) fails to produce long stems and breaks up into floating plantlets. I use ferts including CSM + B but I don't know why the water sprite fails to grow properly. I know that Fulton County has soft water and would like to know if addition of Calcium and Magnesium would help. I have not done that bc I have no data to support that idea. Can someone who has strong growth of water sprite help me understand if or whether this problem has a solution?
