Appearance
The rosette-forming Haworthia grows up to 6 inches (~15 cm) tall and 4 inches (~10 cm) wide. The plant has thick and fleshy leaves arranged in rosettes with pointed tips. The leaves are triangular in shape and have a dark green color. They also have white veins on the upper surface and are covered with white, soft hairs. Additionally, the plant produces spikes of white flowers in the summer.
Common names
Rosette-forming Haworthia is commonly known as "fairies washboard" due to the unique pattern on its leaves. It is also sometimes referred to as "polyploid Haworthia" and "pearl plant".
Uses
Haworthia granata var. polyphylla is commonly grown as an ornamental plant and is suitable for indoor cultivation. It is a popular species among collectors of succulent plants and is often used in rock gardens and container gardens. Additionally, the mucilaginous sap of the plant has medicinal properties and is used to heal wounds, relieve inflammation and reduce pain.
Light requirements
Haworthia granata var. polyphylla is suitable for both indoor and outdoor conditions. When grown indoors, they prefer bright but indirect light to thrive. Being succulent, direct sunlight may burn their leaves, so it is advisable to keep them away from the scorching sun. Outdoors, it is best to place them in a partially shaded area that receives a few hours of direct morning sunlight.
Temperature requirements
These plants can withstand a wide range of temperatures, but they thrive best in warm temperatures ranging from 18-26°C. However, Haworthia granata var. polyphylla can also tolerate low temperatures of about 5-7°C, but it is advisable to keep them away from frosty conditions as they may not survive. To prevent cold damage, it is best to cover them or bring them indoors during winter.
Soil requirements
When it comes to soil, Haworthia granata var. polyphylla prefers a well-draining, sandy soil mix that's rich in organic matter. A mixture of 2 parts of sandy soil, 1 part of perlite or pumice and 1 part of well-decomposed leaf mold or compost is good enough for these plants. The soil should be slightly moist, not waterlogged, to prevent root rot and other fungal diseases.
Cultivation Methods
To cultivate Haworthia granata (Willd.) Haw. var. polyphylla Haw., you should place the plant in a location that receives bright but indirect sunlight. Avoid direct sunlight as it can damage the leaves. You should also ensure that the plant is placed in well-draining soil to prevent water from accumulating around the roots. The soil should be slightly acidic and can be amended with perlite to improve drainage. The plant also thrives in warm temperatures between 60-80°F (15-27°C).
Watering Needs
The plant prefers infrequent but deep watering. You should wait until the top inch of the soil is dry before watering. When watering, ensure that the water drains out of the pot to prevent root rot. During the winter months, you can reduce the frequency of watering, as the plant goes into a period of dormancy.
Fertilization
You can fertilize Haworthia granata (Willd.) Haw. var. polyphylla Haw. once or twice a year using a balanced liquid fertilizer. The best time to fertilize is during the growing season in spring and summer. Ensure that you dilute the fertilizer to half-strength before application to prevent overfeeding, which can damage the plant.
Pruning
Pruning is not necessary for Haworthia granata (Willd.) Haw. var. polyphylla Haw. However, you can remove any dead or yellowing leaves to prevent the spread of disease. You can also propagate the plant by separating offsets from the parent plant. Ensure that each offset has its roots, and you can plant them in a separate pot with well-draining soil.
Propagating Haworthia granata var. polyphylla
Haworthia granata var. polyphylla, also known as the "Polished Window Haworthia", is a small succulent plant native to South Africa. It is a popular houseplant due to its unique and attractive appearance. The plant is relatively easy to care for and propagate.
Propagation methods
Haworthia granata var. polyphylla can be propagated through several methods including:
- Leaf cuttings: Take a leaf cutting from the plant, and let it dry for a day or two to form a callus. Plant the cutting in well-draining soil and place it in a bright, warm location. Keep the soil moist but not wet and wait for new growth to appear in a few weeks.
- Offset division: Haworthia granata var. polyphylla produces small offsets, or "pups", around its base. Once the offset is a few centimeters in size, it can be carefully separated from the mother plant using a clean, sharp knife. Plant the offset in well-draining soil and water sparingly until it establishes new roots.
- Seed propagation: Collect seeds from a mature Haworthia granata var. polyphylla plant and sow them in a well-draining soil mix. Keep the soil moist and warm, and the seeds should germinate within a few weeks. As the seedlings mature, transfer them to individual pots and provide them with bright, indirect light.
Propagation is best done during the spring or early summer when the plant is actively growing and producing new growth.
With proper care and attention, Haworthia granata var. polyphylla can be easily propagated and grown into a thriving plant collection.
Disease and Pest Management for Haworthia granata (Willd.) Haw. var. polyphylla Haw.
While Haworthia granata (Willd.) Haw. var. polyphylla Haw., commonly known as the pearl plant or fairy washboard, is generally a sturdy and low-maintenance succulent, it can still be affected by diseases and pests. Some of the common issues to watch out for and their management strategies are discussed below.
Diseases
1. Root rot: Overwatering or poorly-draining soil can cause root rot, which is characterized by brown, mushy roots. To manage root rot in Haworthia granata, remove the affected soil and roots, let the plant dry out for a few days, and repot in fresh, well-draining soil. Avoid watering the plant too much, and make sure the pot has good drainage.
2. Leaf spots: Fungal diseases can cause leaf spots that are brown or black in color and may have a yellow ring around them. To manage leaf spots, remove the affected leaves and avoid getting water on the leaves when watering the plant. Applying a fungicide may also be helpful.
Pests
1. Mealybugs: These small, white insects can be found in clusters on the leaves and stem of the plant. They suck the sap from the plant, causing yellowing and wilting of the leaves. To manage mealybugs, wipe them off with a cotton swab or wash the plant with a mixture of soap and water. Applying a systemic insecticide may also be necessary in severe cases.
2. Scale insects: These small, brown insects can be found on the leaves and stem of the plant. They also suck the sap from the plant, causing yellowing and wilting of the leaves. To manage scale insects, wipe them off with a cotton swab or wash the plant with a mixture of soap and water. Applying a systemic insecticide may also be necessary in severe cases.
3. Spider mites: These tiny, red or brown insects can be found under the leaves or webs they produce. They suck the sap from the plant, causing yellowing and wilting of the leaves. To manage spider mites, wash the plant with a mixture of soap and water or use a miticide. Increasing the humidity around the plant may also prevent spider mite infestations.
By keeping an eye out for these common diseases and pests and taking appropriate management measures, you can help keep your Haworthia granata (Willd.) Haw. var. polyphylla Haw. healthy and thriving.
