I seem to have trouble with my Red Temple. Twice now I've tried to get it to grow/ stay alive but the bottoms of the stems keep turning white. Eventually the stem melts away and the plant starts to float. Trimming the melted end and re-planting sometimes ends in the same result. I've got gravel and use root tabs and fluval plant light. What am I doing wrong?
Also, the roots from the stems of my ludwigia are super long. Is this normal? What i should i be doing if it's not? They don't seem to be growing taller but the roots keep getting longer.
Thanks
