This plant can withstand temperature fluctuations as long as they do not exceed 32°C. At lower temperatures, the growth of this plant can slow down or cease, and prolonged exposure to cold can damage or kill it. Hot and cold drafts must be avoided to prevent damage.
Soil Requirements
Multidentia crassa (Hiern) Bridson & Verdc. var. crassa needs well-draining, porous soil to grow properly. A potting mix that contains peat moss, perlite, and sand in a ratio of 1:1:1 is suitable. The pH level of the soil should be neutral to slightly acidic, between 6 and 7.5. Additionally, the pot should have drainage holes to prevent waterlogging that can lead to root rot.
Cultivation methods:
Multidentia crassa (Hiern) Bridson & Verdc. var. crassa is an African tropical plant grown for its attractive foliage. It thrives well in a warm and humid climate between 25°C-30°C. It prefers well-draining soil with high organic content, and its ideal pH range is 6.0-7.0. This plant needs bright but indirect sunlight and regular cleaning to remove dust from the leaves.
Watering needs:
Multidentia crassa (Hiern) Bridson & Verdc. var. crassa requires uniformly moist soils. However, avoid overwatering or letting the soil dry out completely. Check the soil moisture regularly by inserting your finger an inch deep into the soil, and if it feels dry, you need to water it. It's best to use room temperature water to avoid shocking the plant with cold water.
Fertilization:
Multidentia crassa (Hiern) Bridson & Verdc. var. crassa is a heavy feeder, and you need to fertilize it regularly during the growing season. Use a balanced fertilizer with an NPK ratio of 10-10-10 and apply it every two weeks. Discontinue fertilization during the winter months as the plant is in a rest phase.
Pruning:
Multidentia crassa (Hiern) Bridson & Verdc. var. crassa generally does not require pruning, but it's essential to remove any dead, damaged, or diseased leaves.

Propagation of Multidentia crassa var. crassa
Multidentia crassa var. crassa can be propagated by various methods such as seeds, cuttings, and division. Each method has its own advantages and disadvantages, and the choice of propagation method depends on various factors such as the availability of plant material, the purpose of propagation, and the environmental conditions.
Propagation by Seeds
Propagation by seeds is the most common method of reproducing Multidentia crassa var. crassa. The seeds should be sown in a well-drained soil mix and kept moist until germination. The ideal temperature for germination is around 20-25°C, and germination can take up to three weeks.
Once the seedlings have a few true leaves, they can be transplanted into individual pots and grown until they are large enough to be planted in the garden or a larger container. It is important to keep the soil moist, but not too wet, and to protect the seedlings from strong sunlight, wind, and pests.
Propagation by Cuttings
Propagation by cuttings is another method of propagating Multidentia crassa var. crassa. This method is ideal for plants that are difficult to propagate by seeds or for those who want to maintain specific characteristics of the parent plant. The cuttings should be taken from the parent plant in spring or summer and should be around 5-10 cm long.
The cuttings should be planted in a well-drained soil mix and kept moist until they root. The ideal temperature for rooting is around 20-25°C, and rooting can take up to six weeks. Once the cuttings have rooted, they can be transplanted into individual pots and grown until they are large enough to be planted in the garden or a larger container.
Propagation by Division
Propagation by division is another method of propagating Multidentia crassa var. crassa. This method involves dividing the parent plant into several smaller plants, each with its own root system. This method is ideal for plants that have multiple stems or a clumping growth habit.
The parent plant should be carefully dug up and divided into several smaller plants, each with its own root system. The smaller plants can be replanted in the garden or in individual pots and should be kept moist until they are established.
Overall, Multidentia crassa var. crassa is a relatively easy plant to propagate, and each method has its own advantages and disadvantages. By selecting the right propagation method and providing the proper care, gardeners can quickly and easily increase their collection of this beautiful plant.
