Crassula Marnieriana Summary

Crassula Marnieriana Physical Characteristics

This slow-growing plant reaches an average mature height of 15-20 centimeters. Its leaves are thick and rounded. They are dark green but have reddish edges whose color gets more intense when the plant is stressed. These leaves are so closely packed that it is almost impossible to see the stem, and they grow from the very bottom of the stem to the top.

There is a cuticle on the leaf surfaces. This wax-like substance reduces water loss on the leaves. The cuticle enables the plant to survive extreme temperatures. It produces an inflorescence in winter when growth conditions a temperature are right. The inflorescence produces pink, star-shaped flowers. The plant clusters by producing many stems.

Crassula Marnieriana Care

The plant doesn’t require too much water owing to the water storage facilities on its leaves. It requires watering in spring, autumn, and winter growing seasons. The amount of water you give the plant varies from season to season and from location to location. The best approach is to use the soak-and-dry method so that you only water when moisture from the previous drink is depleted. You can give it a little water during its dormancy in summer, but only if you notice wilting or other indications of water distress.

It requires at least six hours of sunlight every day. The sunlight can be direct or indirect, so if you are growing the plant indoors, keep it next to an eastern or southern window, close enough to allow it to soak in the sunlight.

It grows well in a well-draining soil to allow excess water to seep. The substrate should only be moist but never waterlogged. Waterlogging causes the plant to develop root rot.

It only requires fertilizer after the original nutrients in the substrate get depleted. A liquid cactus fertilizer can be fed once per year, preferably at the beginning of spring.

DO YOU KNOW? Caring (propagating, pruning/trimming, beheading, watering, …) is a set of skills that is applicable to almost every succulent. Read the in-depth succulent care guide right here >>

Crassula Marnieriana Growth

You can propagate the plant using stem or leaf cuttings. Leaf cuttings are the easiest propagation method because stems are usually covered with leaves. The flowers rarely mature to produce viable seeds. You can behead the plant and use the part for propagation.

This succulent only requires pruning and trimming if the leaves have dried up. You would then need to cut them off to cut them off to keep the plant neat. Repotting isn’t usually necessary because the plant is small and grows relatively slowly. However, you should repot if your plant gets root bound.

It isn’t too susceptible to pests and diseases, but you should look out for mealybugs and scale insects. It would be best to protect it from root rot by planting it on the right pottage and watering it as recommended.
