I recieved some emmersed form Echinodorus Cordifolius today (from the Greenline closing down sale 3 plants for Â£3 odd). I am not going to put them in my tank, but keep them emmersed. As they are in emmersed form already can I just pot them as is and grow them 'in the open' like a regular potted house plant? I know that if I was going from submerged to emmersed they would need a humid environment, but is this necessary as they are already in an emmersed form? I hope not! Any advice appreaciated (I'm also wondering about watering them and whether I need to keep the plant pot 'boggy' ) FWIW... They are just over 2ft long from base to tip with a thick clump of healthy roots and in great condition. The label says: 'mixed cordifolius swords rooted in pots can be adapted to underwater or terrarium use'
