Origin and Common Names
Haworthia marumiana Uitewaal var. viridis M.B.Bayer is a succulent plant that belongs to the family Asphodelaceae. Its genus name (Haworthia) honors the British botanist and entomologist Adrian Hardy Haworth, while the species name (marumiana) refers to the plant's resemblance to the genus Marumia. This plant is native to South Africa and is commonly known as the "Schildkrötenhaut" (which means "turtle skin" in German) due to its rough, bumpy leaves.
General Appearance
The plant has rosettes of fleshy, triangular-shaped leaves that are covered in white tubercles. These tubercles give the leaves their characteristic "turtle skin" texture. The leaves are up to 5 cm long and 2 cm wide and are arranged in a spiral pattern around a central point. The foliage color is light-green or yellowish, and over time, the leaves turn slightly reddish-brown.
The plant usually grows up to 10 cm tall and 10 cm wide. Its roots are fibrous, and the flowers, which appear in summer, are usually small and white.
Uses
Haworthia marumiana Uitewaal var. viridis M.B.Bayer is mainly grown as an ornamental houseplant. This succulent is popular because of its unusual texture and shape, as well as its small size, which makes it ideal for growing in containers and terrariums. This plant is easy to care for and prefers bright, indirect light and well-draining soil. Its rough leaves are an adaptation to its natural habitat, which is arid and subject to high temperatures and low rainfall.

Temperature requirements
Haworthia marumiana Uitewaal var. viridis M.B.Bayer prefers moderate temperatures between 60°F and 80°F. It can tolerate temperatures as low as 50°F, but anything lower than that can cause the plant to become dormant or even die. On the other hand, temperatures that exceed 85°F can cause the plant to wilt or become scorched. It is recommended to keep this plant in a well-ventilated area where temperatures remain consistent.
Soil requirements
Haworthia marumiana Uitewaal var. viridis M.B.Bayer requires well-draining soil that is rich in nutrients. A soil mixture that consists of 50% coarse sand and 50% commercial cactus mix is ideal for this species. This type of soil will allow for adequate drainage while also providing the plant with sufficient nutrients and moisture.
Watering requirements
As a succulent plant, Haworthia marumiana Uitewaal var. viridis M.B.Bayer can store water in its leaves, which means it does not require frequent watering. It is recommended to water the plant thoroughly once a week during the growing season (spring and summer) and to reduce watering during the dormant season (fall and winter). Overwatering can cause the plant to become ill or even die, so it is important to let the soil dry out completely between waterings.
Cultivation methods
Haworthia marumiana Uitewaal var. viridis M.B.Bayer is a small, slow-growing succulent that is ideal for indoor cultivation. It is low maintenance and easy to grow and is generally cultivated in containers, pots, or rockeries. This plant grows in clumps and prefers well-draining soil mixtures that are high in organic matter. The plant growth is slow, and it needs low to moderate sunlight exposure, preferably diffused or filtered sunlight.
Watering needs
Haworthia marumiana Uitewaal var. viridis M.B.Bayer is drought tolerant and can survive long periods without water. However, it does not mean it can survive without any water at all. Overwatering can be detrimental to the plant's growth, and it is essential to allow the soil to dry out between watering sessions. During the growing season, typically spring to fall months, it is required to water the plant regularly, and during the dormant season, it requires minimal or no watering until new growth appears.
Fertilization
Fertilization is not critical for Haworthia marumiana Uitewaal var. viridis M.B.Bayer, but it can benefit from a balanced fertilizer application. During the growing season, a monthly dose of liquid fertilizer can be added to the watering regime to promote healthy growth. It is recommended to use a balanced 10-10-10 NPK fertilizer for the plant's healthy growth.
Pruning
Haworthia marumiana Uitewaal var. viridis M.B.Bayer does not require pruning as such, apart from removing dead or discoloured leaves using a sharp, clean knife. This plant does not typically grow tall and happens to be a clump-forming plant with rosettes. In case the plant outgrows its pot or desired size, it can be divided into smaller clumps, which can be repotted in individual containers, rock gardens, or terrariums.
Propagation of Haworthia marumiana Uitewaal var. viridis M.B.Bayer
Haworthia marumiana Uitewaal var. viridis M.B.Bayer is a small succulent plant that is easy to propagate. The plant can be propagated by various methods, including seed propagation, leaf cutting, and offsets.
Propagation by Seed
Propagating Haworthia marumiana var. viridis through seeds is an easy process. Collect ripe seeds from the parent plant and sow them in a well-draining soil mix. Cover the soil surface with a thin layer of sand or vermiculite, and keep the soil moist but not soggy. Keep the seed tray in a warm and bright area but away from direct sunlight. Germination should occur within two weeks, and after a few months, the seedlings can be transplanted into individual pots.
Propagation by Leaf Cuttings
Haworthia marumiana var. viridis can also be propagated by leaf cuttings. Gently remove a healthy leaf from the parent plant, making sure to keep an inch of the stem attached. Leave the cutting in a dry and shaded area for a few days until the cut ends have calloused over. Fill a well-draining pot with a mixture of perlite and sand, and lightly bury the cut end of the leaf in the soil mix. Water sparingly and avoid getting water on the leaf. The leaf cutting should start developing roots and producing new leaves within a few weeks.
Propagation by Offsets
Haworthia marumiana var. viridis produces small offsets that can be easily separated and transplanted into individual pots. Gently remove the offsets from the parent plant and leave them on a dry surface for a few days to let the cut ends callous over. Plant each offset into a well-draining soil mix and water sparingly. The offsets should establish roots and start growing within a few weeks.
Disease and Pest Management for Haworthia marumiana Uitewaal var. viridis M.B.Bayer
Haworthia marumiana Uitewaal var. viridis M.B.Bayer is a small succulent plant that requires minimal care. However, like all plants, it is susceptible to diseases and pests that can affect its growth and survival. Therefore, it is essential to learn about common diseases and pests that might affect Haworthia marumiana and ways to manage them.
Common Diseases
Fungal diseases are common in Haworthia marumiana plants, especially if they are grown in humid or wet conditions. One of the most common fungal diseases is root rot, which is caused by overwatering or poor drainage. Symptoms of root rot include yellowing leaves, wilting, and a foul odor coming from the soil. To prevent root rot, make sure to water your plant only when the soil is completely dry. Also, ensure that the pot has adequate drainage to avoid water buildup in the soil.
Leaf spot is another fungal disease that can affect Haworthia marumiana. It causes brown or black spots on the leaves, leading to their yellowing and falling off. Leaf spot is usually caused by high humidity and poor air circulation. To manage this disease, prune the affected leaves and ensure that the plant is placed in a well-ventilated area with good air circulation.
Common Pests
Haworthia marumiana is relatively pest-resistant but may still be affected by common pests like spider mites and mealybugs. Spider mites are tiny pests that suck on the sap of the plant, causing yellowing and wilting of the leaves. They are usually found on the underside of the leaves and can be controlled by using insecticidal soap or neem oil. Mealybugs, on the other hand, are white, cotton-like pests that also suck on the plant sap. They are usually found at the base of leaves or where the leaves attach to the stem. To manage mealybugs, wipe them off with a cotton swab dipped in alcohol or use insecticidal soap.
In conclusion, the key to disease and pest management in Haworthia marumiana is maintaining good plant hygiene practices, such as providing adequate airflow, not overwatering, and removing dead plant tissue promptly. By being proactive in managing diseases and pests, you can keep your plants healthy and thriving for a long time.
