Once a week fertilize with a balanced fertilizer such as 20-20-20 diluted to half the strength recommended on the label.
Asclepias curassavica produces a robust plant when started from seed. It can be propagated from cuttings of green stem cut underwater and treated with rooting hormone. The stems are then placed in vermiculite or in potting soil kept continuously moist.
