We were told a wonderful piece of advice this week, from a man who grows a lot of euphorbia. Euphorbia oozes a milky sap when the stems are cut or broken, and this can cause a lot of irritation to your skin if it drips onto you. So this lovely gentleman told us to do the following: Immediately after you cut a euphorbia, make another cut underneath. This will stop the flow of sap and prevent any harm or potential harm coming to your skin. How good is this advice? Perfect, we would say, for growers and cut flower arrangers.
