i currently grow A.portodora,robodora,jacks giant, colocasia thai giant.i have large raised flower beds with heavy ammending
of compost,peat,coco coir..they get planted right out in the beds..they get nearly full sun..they do well..i do keep them fairly well
watered..one thing i know i need to do better at is fertilization..one yr i did fertilize heavy and all my EE's grew to monsters !!
hopefully this yr i will remember to do same again..lol
i think reason my EE's do well in full sun is i get them use to being out in more sun.. now theyve been outside (still in pots) and brought in
at nite..but if nite temps hold in high 50sF..i will plant out..
hope you are successful.. let us know..good luck !!!!
