How to Grow Haworthia cooperi var. truncata 'Ice Lantern'? A Detailed Guide to the Latest Cultivation Methods

Haworthia cooperi var. truncata 'Ice Lantern' is a succulent plant whose fleshy leaves are crystal clear and shaped like an ice lantern, which is why it is called 'Ice Lantern' Haworthia. It is a top-grade variety among Haworthia cooperi and is called a living sculpture. Below, the editor of Qannong Network introduces the cultivation methods for 'Ice Lantern' Haworthia!

Cultivation Methods for 'Ice Lantern' Haworthia

1. Light: 'Ice Lantern' Haworthia by nature prefers a cool and ventilated environment. Generally, it is not suitable to place it directly in the sun for exposure; instead, place it in a semi-shaded environment with relatively good temperature and humidity.

2. Watering: 'Ice Lantern' Haworthia is relatively drought-tolerant. You can follow the principle of not watering until dry, and watering thoroughly when you do. When watering, pay attention to properly controlling the amount, and at the same time place the pot in an environment with good drainage to avoid water accumulation.

3. Humidity: 'Ice Lantern' Haworthia needs to maintain a certain level of humidity so that its leaf lobes look better. If the surrounding environment is relatively dry, you can spray water on the surface of the plant to maintain its humidity. If this is not effective, you can cover the plant with a plant cover, but the cover must be opened every day to let the plant breathe.

4. Fertilizer: 'Ice Lantern' Haworthia generally does not need much fertilizer, and newly planted plants are not suitable for fertilizing. For plants that have been grown for several months or one to two years, apply a small amount of fertilizer appropriately during the growing season —— spring and autumn —— to ensure their growth.

5. Repotting: Because the base of 'Ice Lantern' Haworthia secretes an acidic substance, and this acidic substance corrodes the soil, it must basically be repotted once a year. The repotting period is generally in spring or autumn, or when you find that the plant stops growing during the growing season, then it is time to repot promptly.

Precautions for Growing 'Ice Lantern' Haworthia

1. During high summer temperatures, 'Ice Lantern' Haworthia enters a dormant or semi-dormant state, with slow or completely stalled growth. It can be kept in a ventilated, cool and dry place to prevent the hot, humid environment from “steaming” the plant to death. Avoid exposure to strong sunlight, do not water too much, and stop fertilizing. Wait until the weather cools in autumn before resuming normal care.

2. In winter, if the minimum nighttime temperature is around 8℃ and the daytime temperature is above 15℃, the plant can continue to grow and should be watered normally; if watering is reduced to make the plant dormant, it can tolerate low temperatures of 3℃~5℃, or even short-term low temperatures of 0℃. If it remains in a low-temperature environment below 5℃ for a long time, the plant will not die, but frost damage marks will remain on the leaf surface. Therefore, the overwintering temperature for Haworthia cooperi is best kept above 5℃.

Propagation Methods for 'Ice Lantern' Haworthia

Haworthia cooperi can be propagated by division in conjunction with repotting. You can also dig out the young offsets beside the mother plant during the growing season; both rooted and unrooted ones can survive. Plant rooted ones directly; for unrooted offsets, let them dry for 1 to 2 days until the wound is dry before planting. Newly planted plants should not be watered too much to avoid rot. After new roots grow, resume normal care. You can also choose plump, healthy fleshy leaves during the growing season for leaf cuttings. After inserting, keep the potting soil slightly moist; they easily root at the base and produce small buds. Once the small buds are somewhat larger, plant them separately.

Sowing is also one of the propagation methods for Haworthia cooperi, but it requires artificial pollination. Seeds can be sown as soon as they are collected. The sowing soil can be made by mixing 3 parts vermiculite with 2 parts leaf mold or peat soil. Before sowing, it is best to sterilize the soil at high temperature to eliminate pathogens and insect eggs inside. After sowing, cover with a piece of glass, and seedlings will emerge in about 20 days. After emergence, remove the glass, pay attention to ventilation, do not let the soil become excessively dry, and when the seedlings are too crowded, take care to separate and transplant them. Among the sown seedlings, some variant plants may appear. You can select young plants with compact form, thick fleshy leaves, high transparency of the “window”, and prominent vein patterns to keep as stock plants. If you find seedlings with leaf colors different from the others, also pick them out; perhaps when they grow up, one will be a precious variegated plant.
