How to Grow and Care
They are semi hardy, make sure that your Myrtillocactus are not exposed to temperatures below -4°C or they may die, nevertheless it is a good advice never let the nighttimes temperatures fall below 10°C.
Water regularly in summer but allow to dry fully before watering again. Need a well-drained soil mix with small gravel added to ensure drainage.. During the winter months they should be rather kept dry and water is restricted to only enough to keep the stems and branches from shrivelling.
Since they are big sized plants need plenty of space for their roots, repotting should be done every other year or when the plant has outgrown its pot. Exposure: Light shade when young, full sun later...
Propagation: Cuttings in summer (Cuttings will root only in hot weather.
Cuttings must be kept very dry to root)
It is generally not toxic.
It grows actively in spring and autumn.
It combines well with Sedum clavatum.
