Welcome, Modesto. I assume yours is Pteridophyllum racemosum - this is a woodland plant, and as such, likes dappled shade or shadier situations. It also likes that most difficult of all things, moist but well drained, fertile soil. That means they don't like to suffer any shortage of water, but do not appreciate being wet all the time. It prefers cool summers, which I suspect you don't have, so if yours get sun, make sure you shade them and keep them well watered. Does better in soil that's been enriched with good garden compost or composted manure or any humus rich organic material. Link here with some information, though it doesn't say much more than I've already said
