Does anyone have any advice on Proserpinaca palustris? My tank stuff is slow but good, the tub-raised stuff I have outside is so pale it is almost white. Also, since it is in a tub and not around fish, can I add a soluble fert, like prolific, peters, Schultz, or miracle grow? How about chelated Iron?
