Rodrigo, I haven't grown them from seed. I bought a small plant intending to put it in the ground. Meantime I put the whole put in a plastic icecream container. full of water. The irrigation system keeps the icecream container full of water, about a third of the way up the pot. It's been sitting there like that for over 2 years now (OK, I've been busy!).. It's still looking good without me having done anything. Now you've reminded me that I have to plant it out ............. when I get some spare time.
