water info |
Euphorbias milii are very drought tolerant but will grow faster if they receive some summer water, usually every couple weeks to a month once established (let the plant dry out between waterings). If you aren’t getting summer growth you may be underwatering. These plants prefer a dry winter; outdoors in central California, they will need little supplemental winter water once established. If your crown of thorns defoliates that does not mean it’s dead. This happens when frost rolls through, or also when water is withheld too long. If it’s during summer you are probably underwatering. |
