Q.Mediterranean Plant turns brown, why?
Bought three of theses plants Mediterranean Spurge Swan Plant. Potted in full sun and turned brown, watered every two weeks. Why the browning?
Also how do you care for them in winter? They look dead.

This plant, also known as Euphorbia, has some specific growing requirements. Here are articles you can check to see if your plants are receiving what they need: https://www.gardeningknowhow.com/ornamental/cacti-succulents/euphorbia/growing-euphorbia-plants.htm
Deep watering may have allowed the roots to stay wet for too long, or your plants may have contracted a fungus. You may want to prune the bad stems down at the base of the plant, and if you do decide to prune them back, please wear gloves - the sticky substance inside them is toxic.
