How do you care for a Crassula Marnieriana?
Crassula is very easy to grow if you can meet a few essential requirements. Read this comprehensive guide to find out how to keep your Marnieriana in top condition.
Watering Crassula Marnieriana
Over-watering succulents is the biggest mistake we usually make in thinking we’re doing them a favor.
Too much water and especially a lumpy and poorly drained substrate will cause fungi to appear and multiply, leading to the plant’s death.
Marnieriana only needs very little watering, which makes it the ideal succulent for the summer season, so no need to worry about it during the holidays!
On average, Crassula Marnieriana should be watered twice a week during the summer and once every 7 to 10 days the remaining period of the year.
Outdoors: in summer and spring, water the plant thoroughly, especially in summer, as the substrate dries more quickly because of the heat.
But despite this, it’s still very important to make sure that the substrate is completely dry between waterings. During winter and autumn, the substrate takes longer to dry, so you should pay more attention to the “when” and “how much” when watering the succulent.
Indoors: Being indoors means that the substrate takes longer to dry, especially in winter, so a little water is always sufficient.
When watering, do not wet the leaves, but only the soil, especially during the summer season when there is more exposure to sunlight and therefore a greater risk of burns.
If you have your Crassula Marnieriana in a pot with a saucer, don’t forget to empty the saucer of water residues after 30 minutes from every watering.
A high-quality cactus fertilizer will surely have a positive impact on your Crassula Marnieriana.
It is true that succulent plants seem self-sufficient and do not require much maintenance, but by adding fertilizers, we promote their health and growth.
Fertilize your Crassula Marnieriana from time to time in spring and summer to give it enough energy to fight insects and disease-causing micro-organisms.

Pruning is useful for Crassula Marnieriana plants because it keeps them healthy. It’s also beneficial to make them compact once they become over time leggy and aesthetically unpleasant.
The pruning process is best done in spring or after the blooming period.
Crassulas are not demanding in terms of soil pH, but they do require a very porous soil with a high drainage capacity. In their native environment, they generally grow in rocky quartz fields, and most of them thrive in sandy or even rocky soils.
The ideal soil for succulents is one that keeps enough water to allow them to absorb what they need, but which is still fast drying so the roots don’t rot.
Our Crassula Marnieriana succulent is no exception: Use commercial potting soil mixes designated for use with succulents. We highly recommend this Cactus and Succulent Blend Soil Mix because it drains well while absorbing the right amount of water without any risk of rotting.
Succulent leaves are usually capable of generating a new plant. This method (called propagation by cuttings) is easy and effective to propagate.
Crassula Marnieriana is one of the easiest succulents to propagate. You can proceed as follows:
Remove a cutting from the mother plant and let it dry for about 3 days in a shady place (to prevent the cutting from rotting when it is placed in its new pot).
Once the cutting has dried, fill a pot with a combination of cactus soil and sand, then push the end of the cutting directly into the compost and let it take root (roots should form in as little as 3 weeks). Put the pot in a place where there is intense but indirect sunlight.
To keep your soil and sand mixture moist and stimulate root growth, spray it moderately from time to time. After a while tug at the succulent gently: if you feel some resistance from the roots, it means it’s well-rooted. At this stage, you can move it to another well-drained pot with good cactus soil and take care of it as you would the mother Crassula Marnieriana plant.
Remember that Crassula Marnieriana, like most other Crassulas, can perform well in the same pot and with the same soil for many years. So Repot if necessary (e.g. when the whole pot is full of roots and you want to give it some room). Repot preferably in spring, at the beginning of an active growing cycle.
Before you start repotting, check first that the soil is dry. Gently separate the pot from the plant. Remove the old soil from the roots and place your Marnieriana in a new pot containing a fresh potting soil. Keep it dry for about one week, then start watering it lightly to prevent root rot.
Pests & diseases
Marnieriana is quite resistant, therefore rarely attacked by pathological agents. But keep in mind that in dry and very hot conditions it can suffer from mealybugs, but don’t worry, you can easily get rid of them with a brush soaked in pharmacy alcohol, or with an anti-bug pesticide.
In our opinion, any pest or disease problem is usually due to some carelessness. For instance, excess moisture is problematic because it causes root rot and promotes, among other factors, the rise and multiplication of pests.
