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

Haworthia cooperi var. truncata 'Ice Lantern' is a succulent plant whose fleshy leaves are crystal clear and shaped like ice lanterns, which is why it is called Ice Lantern Haworthia. It is a premium variety among Haworthia cooperi, known as a living sculpture. Below, the editors of Qiangnong Network introduce the cultivation methods for Ice Lantern Haworthia.

Cultivation Methods for Haworthia cooperi var. truncata 'Ice Lantern'

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 harsh exposure; instead, place it in a semi-shaded environment with relatively good temperature and humidity.

2. Watering: Ice Lantern Haworthia is relatively drought-tolerant. Follow the principle of not watering until the soil is dry, and watering thoroughly when you do. When watering, be careful to properly control the amount, and at the same time place the pot in an environment with relatively 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 use a spray bottle to mist the surface of the plant to maintain its humidity. If this is not effective, you can cover the plant with a plant cover, but be sure to open the cover every day to let the plant breathe.

4. Fertilizer: Ice Lantern Haworthia generally does not need much fertilizer. Newly planted Ice Lantern Haworthia is not suitable for fertilizing. For plants that have been growing for a few months or one to two years, you can apply a little fertilizer appropriately during its growing season——spring and autumn, to ensure its growth.

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

Precautions for Growing Haworthia cooperi var. truncata 'Ice Lantern'

1. During high temperatures in summer, the Ice Lantern Haworthia plant enters a dormant or semi-dormant state, growing slowly or completely stagnating. You can place it in a ventilated, cool, and dry place for care, so that a stuffy, humid environment does not “steam” the plant to death. Also avoid harsh sun exposure, do not water too much, stop fertilizing, and wait until autumn cools down before resuming normal care.

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

Propagation Methods for Haworthia cooperi var. truncata 'Ice Lantern'

Haworthia cooperi can be propagated by division in conjunction with repotting. You can also dig up the young offsets beside the mother plant during the growing season; both those with roots and those without roots can survive. Plant those with roots directly. For seedlings without roots, let them dry for 1 to 2 days until the wounds are dry before planting. Newly planted plants should not be watered too much to avoid rot. After new roots grow, carry out normal care. You can also select plump, healthy fleshy leaves during the growing season for leaf cuttings. After inserting them, keep the potting soil slightly moist; they will easily root at the base and grow small buds. Once the small buds are a bit larger, they can be planted 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 prepared by mixing 3 parts vermiculite with 2 parts leaf mold or peat moss. 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; seedlings emerge in about 20 days. After the seedlings emerge, remove the glass, pay attention to ventilation, and do not let the soil become excessively dry. 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 rosettes, thick fleshy leaves, high transparency in the “window,” and prominent vein patterns to keep as stock plants. If you find small seedlings with a leaf color different from the others, also select them out; they might grow up to be a precious variegated mutant plant.
