Soil
Christ’s thorn (Euphorbia milii var. splendens) is not a demanding plant regarding the type of soil and can grow in chalk, loam or sand.
-
The chalky soil is pale and contains chunks of calcium-rich rock. It is a fertile and well-draining soil, almost always alkaline.
-
The loam soil is dark, rich in organic matter but balanced in minerals. It offers the best of all worlds, retaining enough water for the plants, but allowing excess moisture to drain away. This is the most desired type of garden soil, perfect for most plants.
-
