Hi Everyone! I know this post is very old...but I am desperately looking for an Synadenium Grantii (African Milk bush, African Poinsettia). I really wanted to get it as a present for a dear friend who loves the plant and has been wanting to get one. I would really love a larger plant, instead of just a cutting - one that actually looks like a gift! :) If anyone has one they are willing to part with (sell or trade), or knows where I can purchase one, I'd be very grateful! Please contact me! Anywhere in the US would be fine.

I saw this happen to dry hot sunny conditions. I don't think it's fungus however, I see no harm using ornamental spray on it as long as you don't over do it. Mine are starting to cork at the base now. It must be hard as wood, if not, it may be something else.

If you have several, they must grow here in Austin. I would really like one. Thank you!

Cut until you're in obviously healthy tissue, making the last cut with a clean knife. Have a bucket of lukewarm water nearby and wear appropriate PPE. The water's for staunching the flow of latex, the PPE's to protect you from chemical burns. Cut a healthy segment and stick the dripping end into the water for a minute, then set aside on some newspaper to dry and stop flowing. Wait a week, then dab the ends in Rootone, wedge slightly into soil (one that's at least half-porous material) and prop up with rocks/pots/stakes, Put in a sunny location and don't water them. Mist the stems every few days. You'll likely see growth (and therefore roots underneath the soil) in two months. It'd be good if the atmosphere was warm (ideal would be a heat mat for the night).
