How Do You Care For Crassula Rupestris?

How do you care for Crassula Rupestris?

Crassula Rupestris (Thunberg): A low-maintenance plant with an unusual shape. In South Africa and Namibia, this soft succulent grows as a tiny, branching shrublet in rocky crevices.

Its thick, triangular leaves seem stabbed by its long, slender stems, which reach a maximum length of 12.0″ and bend and trail from containers. When providing care, the following considerations should be taken into account:


Crassula Rupestris grows in full light and is tolerant of extreme situations. It is also tolerant of partial shade, however this succulent grows more quickly when exposed to more sunshine.

To retain its vibrant green foliage color and compact growth pattern, it requires at least six hours of direct sunshine every day or five hours with some indirect morning/evening sun.

If your window faces south, this is the ideal location for your Crassula Rupestris plants. They will develop more quickly as a result of the additional light and heat from the sun than they would if they were in less strong sunshine or shade elsewhere.


The Crassula Rupestris is a drought-resistant succulent that thrives in pots with little watering. The plant requires watering approximately once every ten days and should never be left in stagnant water. To grow Crassula Rupestris indoors, put it in well-drained soil and water it frequently but not excessively. This is possible regardless of where you reside.

In general, the Crassula Rupestris is a plant that can survive for extended periods of time without water or with very little water.


The Crassula Rupestris likes well-drained soil, as it is prone to root rot in very damp situations. A suitable mix would contain around 50% potting soil and 50% sand. Sand offers adequate drainage while retaining sufficient moisture to enable these thirsty plants endure extended summer droughts.

A great approach to determine whether the soil drains well enough is to place a piece of damp newspaper on top and check back in an hour or two.

If the majority of the paper has dried up, your potting mix may require additional sand to provide proper drainage for these plants.


Another critical factor to consider is the temperatures at which this plant grows. Crassula Baby’s Necklace enjoys typical summer temperatures of up to 70 degrees Fahrenheit (21 degrees Celsius). You must keep your Crassula Baby’s Necklace against frost damage.

This plant can live in temperatures as low as 50°F (10°C). If you reside in a location that experiences freezing temperatures throughout the winter, it’s better to put it in a container that can be brought indoors during the cold season.


The Crassula Rupestris likes high humidity. Humidity levels below 60% trigger the plant’s roots to turn black and brittle. You should provide the necessary amount of humidity to ensure this succulent is not left dry or in high temperatures with low humidity.


This plant rarely gets enough light and grows quickly. With regular repotting, you can keep this beautiful plant in the pot it was originally placed into, or change it to a more suitable pot for its needs and requirements.

Repot young plants every 2–4 years once the root system has become well established. At the same time, change their location and find a location with slightly more light, bigger pots, etc.


While you are not need to fertilize your Crassula Baby’s Necklace plant, providing it with additional nutrients will aid in its growth and stimulate blooming. This sort of plant demands a great deal of energy in order to bloom. Therefore, supplementing it with additional nutrients throughout the flowering season will assist in meeting your plant’s nutritional requirements.


Stem cuttings are the simplest and quickest method of propagating these plants. They can be reproduced from leaves, but I find the procedure to be more time consuming and tiresome. I’ve had better results using stem cuttings. If you wish to experiment with leaf propagation, ensure that you use the complete leaf that wraps around the stem, including the base. Carefully slide the entire leaf down the stem, taking care not to harm it. Arrange the entire leaf horizontally on the soil.

How often do you water Crassula Rupestris?

While Crassula Baby’s Necklace plants are drought tolerant, they are extremely prone to root rot. Thus, it is preferable to underwater the plant than to overwater it.

There is no particular routine for watering your Crassula plants. Watering schedules might vary according on temperature and humidity levels. Allowing the soil to dry completely before watering is the best approach to ensure that you are not overwatering your plant.

During the summer, you’ll likely need to water your Crassula Baby’s Necklace plant every 7-10 days. During the winter season, irrigation should be reduced to approximately every 10-14 days.

If you accidentally over-water your plant’s pot, do not leave it there, since this may result in root rot and fungal illnesses! Allow a few minutes for your plant to absorb all the water it requires, and then drain any excess water.

Is Crassula Rupestris plant same Crassula Perforata?

Crassula Rupestris have small, tight leaves that are more pointy and star-shaped in appearance compared to Crassula Perforata. As the leaves develop, they spread and stack on top of one another. The leaves circle around the stem, making an interesting design. Pale green leaves with ruby red borders. Increased sun exposure increases the color.

At first, the plant grows straight up, but as it matures, it sprawls and looks to flow out of the pot. They can reach a length of almost one foot (30cm). The blooms produced by Crassula Perforata and Crassula Rupestris are another distinction.

Crassula Rupestris produces clusters of blooms that resemble Baby’s Breath. The clustered flowers are spherical, but the blossoms of Crassula Perforata are more elongated and thrust outwards. The hues are various tones of pink with a hint of yellow. These plants are quite stunning to look at, even more so when they are in flower.

How do you Propagate Crassula Rupestris?

The easiest and quickest way to propagate these plants is through stem cuttings. They can be reproduced from leaves, but the following are procedures to fllowed;

  • Collect a stem and allow it to dry for many hours to a day. Because the stems are thin, they should dry quickly. Additionally, it is recommended to take cuttings from healthy-looking plants rather than dried ones.
  • Inject rooting hormone into the cut end. While we normally omit this step, some individuals choose to use rooting hormones to expedite the process and also ensure success.
  • Once the incision has healed and dried completely, insert the cuttings into a well-draining potting mix or lay the leaf cuttings flat.
  • Avoid direct sunlight. Every several days, water or spray the soil.
  • After around two weeks, you will witness the growth of new roots.
  • After around four to six weeks, the stem cuttings should be properly rooted, and new growth should begin to emerge from the top or sides of the stem. Leaf cuttings often take longer since they require the growth of a new plant. Utilize several cuttings in case any of them do not survive.
  • Once the plant is established and rooted, you may move to normal watering rather than misting and reduce watering to once a week or less. As the plant grows, increase the quantity of light it receives.
  • With a few simple techniques and a little bit of patience, you can have a few Crassula Rupestris babies flourishing around your garden.

Why my Crassula Rupestris leaves turning brown?

Brown leaves of Crassula Rupestris are most frequently caused by sunburn. While this plant can tolerate direct sunlight, any extreme weather conditions or abrupt changes in weather, such as a heat wave, might result in sunburn or solar damage.

This has no effect on the plant’s internal structure as long as the condition is transient. If you see the plant being scorched on a regular basis, relocate it to a shadier area or give shade behind taller plants, furniture, or sun screens.

When relocating a plant to a more sunny location, it is a good idea to gradually adapt the plant to avoid stunning or scorching it.

Why my Crassula Rupestris plant shriveled Leaves?

Underwatering is the most prevalent cause of withered leaves of Crassula Rupestris. The leaves will seem dried out, shriveled, and wrinkled. When the leaves are touched, they will feel flat and thin. When this occurs, it indicates that the plant’s water store is depleted and that it is time to water. Simply give the plant a healthy sip of water and it will generally wake up within a day or two.

When watering, it is preferable to properly water the plant rather than sprinkling it here and there. Then wait till it dries out completely before watering it again.

Why Crassula Rupestris plant have mushy brown leaves?

Overwatering is the most prevalent cause of mushy brown leaves on Crassula Rupestris. The plant begins to appear sickly, and the leaves become lighter or transparent. Additionally, the leaves will feel mushy.

These are typically indications that you have overwatered your plant. Simply reduce the amount of water you give the plant and allow it to dry out and recuperate from the excess water. Withhold watering until the plant has totally dried out.

If the soil does not dry up quickly enough, try switching to a quick-draining variety. When these plants are kept in moist soil for an extended period of time, they are prone to root rot.

When a plant turns brown or black, it typically indicates that it is beginning to decay. You can still rescue the plant by removing the rotting dead sections. Anything that seems to be green and viable should be saved for propagation and repotting.

Remember that it is simpler to ‘repair’ an underwatered plant than it is to ‘fix’ an overwatered plant, so err on the side of caution when watering, especially if you are unfamiliar with the plant.

How do you make Crassula Rupestris to Bloom?

As if they are not pretty enough, they get even more beautiful once they bloom. Crassula Rupestris develops clusters of pink and yellow blooms that encircle the plant and change it into an incredible rainbow of hues.

Bear in mind that not all plants are flowering ready, and some may flower at all. Much of it is determined by environmental circumstances that are beyond our control. Here are some strategies for promoting Crassula Rupestris blooming:

Maturity of the Plant

Ascertain if the plant is sufficiently ripe. When a plant blooms, it indicates that it is prepared for reproduction. If the plant is too young, it is simply not capable of reproduction and hence will not bloom. Allow the plant time to grow; typically, a plant that is over three years old and beyond is mature enough to blossom.

Plenty of Light

Assure that the plants receive sufficient sunshine throughout the year and are maintained in a bright position, especially during the colder winter months.

Proper Temperatures

Provide appropriate temperatures to promote blooming. They require a considerable contrast between night and day temperatures, as well as between summer and winter months. Succulents prefer colder nighttime temperatures of 50-550F (10-130C) outdoors or at least 60-650F (15-180C) inside. Succulents, particularly when grown in a controlled setting, prefer a significant change in temperature between night and day to simulate their natural habitat, with the low night temperatures playing a critical role in the plant’s development cycle.


Overwintering your succulents is also necessary if you want to see them bloom. This may be accomplished by keeping desert cactus cold and somewhat dry throughout the winter months. Maintain temperatures just above freezing, between 35-440F (1.5-70C), during the winter months. If maintained indoors during the winter, keep them in a non-heated area or keep the temperature low to offer them with the necessary cold winter time.

Feed or Fertilize

While fertilization is not required, providing your plants with the nutrients they require will aid in their growth and promote blooming. Plants require a great deal of energy to create blooms, and providing them with additional nutrients during flowering season can help them meet their nutritional requirements.

The most often recommended method is to fertilize during the active growth season, which occurs in the spring and summer. Fertilizers are best administered at 1/4 or 1/2 strength, about every two weeks. Avoid fertilizing at the end of the autumn season and during the winter months.

A balanced fertilizer blend diluted to half strength is appropriate and frequently used. Fertilizer mixes made specifically for cactus and succulents are also appropriate.
