I found this idea of planting adenuim on an old adenium forum and found it interesting. What do you think?
"my medium has two layers. one third from the bottom up i place 100% coarse river sand. it has a good retention of moisture and will quickly drain excess water if given a good size drain outlet. the rest of the medium is 50% coarse river sand 50% compost . with this mixture the medium will not be totally dry but will drain off excess water easily."
And this:
"base on the experience and advice shared by collectors, the containers should be wider than it is deep. this is also to influence the shape of the caudex"
And this:
" i dont need the water to reach all the way down.bec. i dont need the adenium to grown many tiny roots all over the pot. i am after the caudex to grow fat. so my logic here is just wet and nourish the caudex directly so it will grow fatter and faster."
