I just got in some beautiful Marsilea quadrifolia from aquariumplants.com yesterday. Included in the shipment was a piece of paper advising me to cut the plants off entirely 1/4" above the pot. I've never heard of anyone on here doing that and wanted to see if that is indeed true. Is there no hope for the four leaf clover type leaves to grow underwater? Will they all just melt away and be replaced by underwater leaves eventually anyway?
