The flowers are star-shaped with six petals and are fragrant and nectar-rich, making them attractive to pollinators like bees and butterflies.
Light Requirements
Haworthia venosa (Lam.) Haw. subsp. granulata (Marloth) M.B.Bayer prefers bright but indirect sunlight. Direct sunlight can cause the leaves to burn, so it is best to place the plant near a window that receives bright but filtered light.
Temperature Range
The ideal temperature range for Haworthia venosa (Lam.) Haw. subsp. granulata (Marloth) M.B.Bayer is between 60-80°F (15-27°C). It can tolerate temperatures as low as 50°F (10°C) but cannot survive temperatures below freezing. It is best to avoid placing the plant in temperatures above 90°F (32°C) as it can cause damage to the leaves.
Soil Requirements
Haworthia venosa (Lam.) Haw. subsp. granulata (Marloth) M.B.Bayer requires well-draining soil that is slightly acidic to neutral (pH 6-7). A mixture of succulent and cactus soil with perlite or sand works well. The soil should be kept moist but not overly wet as this can cause root rot.
Cultivation Methods
Haworthia venosa (Lam.) Haw. subsp. granulata (Marloth) M.B.Bayer, also known as Fairy Washboard, is a small succulent plant that is easy to cultivate. This plant is native to South Africa, where it grows in rocky habitats, so it prefers a well-draining soil mix. It is also drought-tolerant as it can survive without water for long periods, making it a perfect potted plant for indoors and outdoors in warm climates.
To cultivate the plant, place it in bright, indirect light, preferably near a window or under a garden canopy. Protect it from extremes of temperature below 50°F since it is not frost-tolerant. In the growing season, water the plant in moderation every two weeks, allowing the soil to dry out completely between watering.
Watering Needs
Haworthia venosa subsp. granulata prefers a well-draining soil mix with a higher percentage of sand. The soil should never be soggy since this may cause the roots to rot. This plant tends to rot easily if the soil is too moist or if the plant sits in water for too long.
For watering needs, the plant is drought-tolerant and prefers moderate water levels. During the growing season, water the plant every two weeks. In winter, reduce watering to once a month, or allow the plant to go dormant. Water from the soil and avoid watering from the top of the plant as this could lead to waterlogging in the roots.
Fertilization
Fertilize Haworthia venosa subsp. granulata during the growing season using a low-nitrogen cactus fertilizer. Apply the fertilizer at half strength once a month during the growing season to avoid overfeeding the plant. Alternatively, you can use a balanced houseplant fertilizer diluted by half and fed monthly to offer a steady and mild nutrient supply.
It is important to note that overfertilization can result in a reduction in growth and an increase in pest infestation, and ultimately the death of the plant. Rational feeding will help keep the plant healthy and prevent pest infestations.
Pruning
Haworthia venosa subsp. granulata does not require pruning, but you can pinch off dead or damaged leaves to maintain the plant's appearance. Use sterilized scissors or garden shears to cut off the leaf at the base, which will prevent infection or transmission of diseases to the rest of the plant. Since the plant produces offsets, you can separate them and propagate them to make new plants if you desire.
It is essential to keep the plant free of debris, dead, or damaged leaves as these provide hiding places for pests, and disease pathogens.
Propagation of Haworthia Venosa subsp. Granulata
Haworthia venosa subsp. granulata can be propagated through various methods, including division, leaf cuttings, and seed propagation.
Propagation by Division
Propagating Haworthia venosa subsp. granulata through division involves separating the offsets from the parent plant. The best time to divide the plant is during the growth period, which is during the spring and summer months.
Firstly, the parent plant should be carefully removed from the pot, then the offsets should be separated using a clean, sharp knife that has been sterilized. The offsets should be removed together with some roots and should be planted in a new pot with well-draining soil.
Propagation through Leaf Cuttings
Propagation through leaf cuttings is another simple method that can be used to propagate Haworthia venosa subsp. granulata. This method involves gently removing a healthy leaf from the parent plant and planting it in well-draining soil.
It is essential to make sure that the leaf's cut end is allowed to dry and form a callus for a few days before planting it in soil. Once the callus has formed, the leaf can be planted in well-draining soil, and it should be thoroughly watered. The planted leaf should be kept in a warm, bright area but out of direct sunlight.
Propagation through Seeds
Propagation of Haworthia venosa subsp. granulata through seeds is another option for plant propagation. The seeds are typically tiny, and this method requires patience and expertise to obtain the best results.
The seeds should be planted in moist, well-draining soil, and they should be kept in warm and bright conditions. The soil should be kept continuously moist until the seedlings emerge, which can take several weeks. Once the seedlings have emerged, they should be kept in a warm and bright area, out of direct sunlight.

Diseases
One of the most common diseases that affect Haworthia venosa (Lam.) Haw. subsp. granulata (Marloth) M.B.Bayer is root rot. It is caused by overwatering the plant or keeping it in poorly drained soil. Signs of root rot include yellowing or wilting leaves, blackened or mushy roots, and a foul odor. To manage root rot, the infected plant should be removed from its pot and washed gently to remove any infected soil. The roots should also be clipped to remove any damaged or diseased areas. Transplant the plant into well-draining soil mix and reduce watering to prevent any further damage to the roots.
Haworthia venosa (Lam.) Haw. subsp. granulata (Marloth) M.B.Bayer can also be affected by fungal leaf spot diseases. These diseases manifest as brown or black spots on the leaves of the plant. To control leaf spot diseases, ensure that the plant is kept in a well-ventilated area and avoid water from getting on the leaves. Remove any infected leaves and keep the soil clean and dry to prevent the disease from spreading.
Pests
Mealybugs are one of the most common pests that can affect Haworthia venosa (Lam.) Haw. subsp. granulata (Marloth) M.B.Bayer. These pests appear as small, cottony masses on the leaves or stems of the plant. They damage the plant by sucking the sap from the plant tissues, causing the leaves to become yellow and wilted. To manage mealybugs, use a cotton swab soaked in a solution of rubbing alcohol and gently dab it on the affected areas. Repeat this process until all the mealybugs have been removed. Alternatively, insecticidal soaps can be used to control the infestation.
Spider mites are another common pest that can infest Haworthia venosa (Lam.) Haw. subsp. granulata (Marloth) M.B.Bayer. These pests appear as tiny, red spiders or black dots on the leaves of the plant. They damage the plant by sucking the sap from the plant tissues, causing the leaves to become dry and yellow.
