Plant my crown of thorns

Plant preferably between September and the end of November or between March and the end of April, when the winter reserves are formed and the temperatures are not too low. Bury the roots a few centimeters so that the foliage is flush. Fill and pack well around the plant so as not to leave a pocket of air. Water copiously just after planting. If you are planting in a pot, use one whose volume corresponds to that of the plant, otherwise you will have to water it too often. You can use gravel at the bottom under mixture of soil, compost or compost for better drainage.
