easy to grow from 1/2-1 in. cuttings set in soil where they are to grow; transplanting them can be touchy; in containers they have no tap root and require lots of water; they are classified as weeds in Arizona and are rarely found in nurseries; they are able to limit competition from other plants by taking up salt from deep ground water, accumulating it in their foliage, and from there depositing it in the surface soil where it builds up concentrations temporarily detrimental to some plants; the salt is washed away during heavy rains (or deep watering); very susceptible to scale (leaves start to turn yellow and small, stationary, flattened, elliptical, grey or blackish scale insects are present — use Malathion® immediately). |
