The Care From spring through late fall, water the crown of thorns plant when the soil is dry at a depth of about an inch, which is about the length of your finger to the first knuckle. Water the plant by flooding the pot with water. After all of the excess water has drained through, empty the saucer under the pot so that the roots aren’t left sitting in water. In winter, allow the soil to dry to a depth of 2 or 3 inches before watering. Wear gloves when working with crown of thorns. The plant is poisonous if eaten and the sap causes skin irritations. Crown of thorns is also poisonous to pets and should be kept out of their reach.
