Crassula Perforata

Crassula Perforata Plant Origin

Crassula perforata (String of Buttons) is a member of the genus Succulents in the vast family Crassulaceae. Crassula is a genus of tropical evergreen plants that grow only in the southern hemisphere. They call this plant the ‘money tree,’ a tree of happiness in everyday life. It translates to Crassul, meaning “fat,” which characterizes the fleshy and dense structure of the leaves. This plant’s natural habitat comprises Africa, Madagascar, and the Southern regions of Arabia. According to various classifications, the genus includes 300-500 species.

Plants characteristics.

Growing your succulents in containers is a fun and rewarding hobby. You’ll also enjoy the low maintenance cost if you select plants that perform well in your climate. If you’re thinking about starting your Crassula plant, you’ll need to decide whether you want to grow them indoors or outdoors. The best plants for growing indoors are the ones that don’t require much sunlight, and the easiest to grow are the ones that don’t flower.

Appearance description:

The stem is encircled by a ring of leaves that develop in a spiral pattern. With rosy pink margins, they may be rather eye-catching. Star-shaped pale yellow blooms occur around April, but most gardeners cut them off since the dead, desiccated stalks become unappealing once the petals have faded. 

  • The trunk is flat, long, thick, does not branch, and grows through the leaves.
  • Stems grow over 8 inches (20cm) in height and are densely leafy.
  • The leaves can be rhomboid and round, dense, and thick.
  • The leaves are green with bluish hues.

The leaves take on a reddish hue from the intense sun at the edges. The leaves are 1.3″ -1.5″ (3-4 cm ) wide and grow opposite each other in layers; at the bottom, they increase together (stacking up, basically). At the top of the stem, the flowers are miniature, numerous, white with yellowish hues, and fragrant at the beginning of flowering but not later on. Flowering usually occurs for up to 1.5-2 months.

1. Cold hardiness

Subject to night and day temperature differences, the plant develops better. The preferable temperature range in spring and summer during the day is 73-79°F (23-26°C), and at night at about 50°F (10°C). In the fall, ensure you place the pots in a stable environment. The optimal temperature during the fall-winter season is 53°F-59°F (12-15°C). However, it usually withstands temperatures of 42°F-44°F (6-7°C). To encourage flowering: limit watering, reduce the temperature to 53°F (12°C), and the lighting should be bright and diffused.

2. Watering requirements

Water the plant moderately, in small doses, with a pan or dripping. In summer, once a week is enough. Between waterings, dry the substrate. In fall and during the winter holidays, reduce the watering. It is enough to moisten the soil once in 2 weeks (it should dry 1.18 inches or 3 cm deep). It is necessary to drain the water from the container immediately as water stagnation is unacceptable.

Humidity: The flower does not require regular spraying. Avoid increasing the moisture, even in intense heat. Instead, wipe the dust with a damp cloth. Once a month in summer, you can bathe the leaves in a warm shower. Ventilate the room regularly. The plant needs dry, fresh air.

3. Soil

During dormancy, refrain from fertilizing the soil. Revitalizing the plant may continue in late March. It is better to use ready-made liquid mineral fertilizers for cacti and succulents, with high potassium and phosphorus content. You can use low concentration nitrogen fertilizers for young seedlings for the active growth of stems and leaves. Apply fertilizers by irrigation once every two weeks. Florists recommend fertilizing the soil with a weak solution of soluble salt. You can use special tablets and sticks. The soil mixture should be light, not too nutritious (excluding peat), and well-drained. The drainage layer has polystyrene, fine gravel, coarse sand, and crumbs of red brick. Here is the typical soil composition:

  • Sphagnum peat moss
  • Hummus
  • Soil layers
  • Sand
  • Coal (for soil disinfection)
  • Drainage

4. Lighting

The plant consumes a lot of light, up to 4-5 hours a day. Therefore, it is better to darken the windows to prevent direct sunlight as burns can appear, especially in young flowers.

5. Propagation

  • Seeds – Put the seeds in a wide pot with a mixture of sand and soil layers (1:2).
  • Seedlings sink after two weeks. – For growth, you can plant cultivated seedlings in small pots, 2.3-2.7 inches (6-7 cm) in diameter.

Cuttings and leaves

Cut the stem cuttings with a knife and carefully separate the leaves. Dry the fragments for two days in the shade and treat them with crushed charcoal. Then, you can root the plant in a mixture of sand and soil layers or water with active charcoal (1 tablet per glass of water). Also, after the roots appear, transfer the seedlings to separate containers.

You can breed Crassula perforata (String of Buttons) year-round, but it is usual to carry out the procedure in the spring.

6. Repotting

It would be best if you transferred young flowers every year. Usually, gardeners avoid planting mature shrubs frequently because the roots grow and the pot becomes too small. It is better to transplant in the spring. First, prepare the soil, then transfer it to a tank 1 inch (2 cm) larger than the previous one. Remember to cut out infected and dry parts when transplanting. Treat the slices with crushed charcoal. The pots used should be small and shallow, according to the size of the roots. If the flower has not grown too much, you can update the top layer of soil.

How to Care for Crassula Perforata Plants in 6 Simple Steps

If you have a Crassula Perforata plant, then this article is for you. I am going to share with you 5 simple steps that will help you care for your Crassula Perforata plant.

  1. The first step is to provide the plant with enough light. This type of plant does not need direct sunlight but it does need at least some indirect light to grow well. If the area where the plant is kept does not receive any natural light, then it should be placed near a window where it can get some indirect sunlight from time to time.
  2. The second step is to water the Crassula Perforata once every two weeks or so. It should be watered when the soil feels dry and not wet, and make sure that there is no standing water in the container.
  3. Allow the Crassula Perforata to dry by placing it in a warm room (70-80 degrees Fahrenheit) out of direct sunlight for about one week before potting it in a larger pot.
  4. Make sure the new pot has good drainage holes and is not filled with soil, but instead use a peat moss-based or perlite-based medium.
  5. Water regularly until the plant is well established in its new pot, remember to mist frequently throughout the day if it’s hot and humid out
  6. Use a well-draining potting mix, do not use garden soil.


Pruning and Maintenance

Prune (nibble) the top of young stems regularly to form a compact bush. Cut off excessively elongated ‘shoots’ caused by lack of light. Also, note that apical cuttings can take root.

Accumulated water in the soil and a sharp drop in temperature can cause the root and stem to rot. Also necessary to have urgent pruning, quarantine, and transplantation with complete soil replacement. Avoid plaque on the leaves (powdery mildew), high humidity, moldy air, and cold contents. Finally, the deformation of leaves, growth, change in color, and elasticity of leaves means excess fertilizer, moisture, and lack of light.

  • Crassula minor–derived compact species has the synonymous name compacta. It grows well even in a semi-shady place; the stems are straight and grow slowly into shrubs. Its leaves are fleshy, glossy, and green with a reddish edge. The leaves are 0.6 inches (1.5 cm) long and up to 0.4 inches (1 cm) wide. Finally, many white or tiny pink flowers combine into umbrella-like shapes.

– Alba (alba)

  • With the development of branches, the stems pull upwards, growing up to 11.8-15.7 inches (35-40 cm) in height. The leaves are oblong, glossy, smooth, and gathered in a wide opening. Moreover, the leaf plate is medium-sized, 2-2.3 inches (5-6 cm). The color of the leaves is reddish or green with a white and red pattern. Also, this variety has an attractive property – immediately after flowering, the rosette dies. Also, it propagates quickly with lateral protrusions.

Frequently Asked Questions

How fast do a String of buttons grow?

Succulents are popular as houseplants because of their ability to grow and flourish with little water or care. But the amount of time it takes for a plant to grow into a healthy mature plant varies among different species. A string of buttons needs sunlight, moisture, and nutrients to survive and thrive, and it’s very forgiving. If the conditions are right, it will grow and bloom in just a few months. And they die if they don’t receive sufficient sunlight, water, or fertilizer.

How do I propagate a string of buttons?

A string of buttons is easy to grow, so if you’re looking to add some green to your kitchen but aren’t interested in growing your own, there are plenty of succulents you can pick up at any gardening store. Here are three tips for propagating succulents: • First, look for plants that aren’t entirely mature (meaning that the center is still green). This means that the plant hasn’t begun to flower or set seed yet. These succulents will produce fewer leaves, so you’ll want to choose large enough plants, so you don’t have to clip off all of the leaves. • Second, cut the stem where it meets the base of the plant and bury it in damp soil. • Third, water thoroughly. After about a month, the new stem should appear. You can then transplant the whole plant to a larger container and keep it indoors until it grows to its full size.

How do you take care of a string of button plants?

If you notice that your Crassula perforata is growing slowly, the pot you have it in isn’t in direct sunlight or isn’t at the right temperature. You should move your plant to a different location and ensure it is exposed to maximum sunlight. Changing the location of an already established plant can be challenging, but it will be worth getting it enough sunlight, either through sunlight or artificial means. Also, ensure that your plant is getting the proper temperature (Avoid placing it next to a heat vent). When you have your plant at the right temperature, you can expect your plants to thrive and it will experience fast growth. If your plant is placed in a hot environment, its leaves will wither, and it will be unable to grow as expected.

In conclusion, there are a few things that you can do to grow your plants quicker. The biggest thing you can do is make sure that you fertilize regularly. Fertilizing helps the roots grow and helps the plant to absorb nutrients and water. It also helps the plant to produce fruit. You want to fertilize your plants at least once every 3-4 months.

Another thing that you can do to help your plants grow faster is to provide them with light. The more light it receives, the faster the plant will grow. It’s essential to keep your plants in the right conditions. You can do this by checking the temperature and humidity and adjusting them as needed. Finally, it would help if you also took note of the amount of sunlight that your plants are receiving. Plants getting too much sun can wilt, so you should consider moving them to areas with less sunlight.
