I have some Limnophila aromatica in my 50 that are quite healthy. Only problem is that they have developed large root outcroppings from the lower stalks. Not one or two little sprigs, but a snarl of thick roots. Remedy would be just to cut them off. However, I'd like to see if anyone else has had the same problem and what they did about it, if anything. Will it kill the plants to cut them off?
