Methods for Cultivating Thor
Let me tell you about the succulent plant Thor, its cultivation methods. Next, the editor will introduce the information to the netizens.
Princess Thor: Also known as姬Thor. The plant is small, with a height of 6-8 centimeters and a diameter of 8-10 centimeters. The leaves are short and wide, with sparse meat teeth on the edges, and short yellow or red spines at the tips of the teeth. There is a short spine at the top of the leaf.
【Propagation】: Sowing, dividing plants.
Sowing: Sow indoors in March to April, with an optimal germination temperature of 21-24°C. Germination occurs after 14-21 days.
Dividing plants: After the large plant flowers, sets seeds, and dies, small daughter plants will sprout from the base. These daughter plants can be dug out and planted separately when repotting. If the daughter plants have no roots, they can be first inserted into a sand bed, keeping the substrate moist, and then transplanted into a pot after they have developed roots.
【Cultivation Tips】
Temperature: Prefers warm conditions, with the optimal growth temperature being 18-25°C, with daytime temperatures of 22-25°C and night temperatures of 18-21°C. Not cold-tolerant, and during high summer temperatures, ventilation should be ensured.
Light: Loves light, not tolerant of shade. When in the shade, the leaves become narrow and thin, the white powder on the leaf surface decreases, and the plant becomes loose and unattractive. Especially the spines at the leaf tips and edges will change from a bright reddish-brown to a dull color; the beautiful patterns on variegated leaves will fade, affecting the ornamental value. However, during strong summer sunlight, appropriate shading is required. Especially for plants that have been in low light conditions for a long time, they should be avoided from being moved suddenly to a place with strong light, as this may burn the leaves. Avoid rain, not suitable for outdoor cultivation, suitable for indoor pot cultivation.
Watering: Prefers a slightly dry soil environment, with strong drought resistance. During the growing period, watering should be controlled appropriately, following the principles of "do not water until dry, water thoroughly when watering" and "better dry than wet." Frequent watering should be avoided, as excessive moisture in the pot soil can cause yellowing of the leaves and root rot. However, it should not be too dry, or the plant's growth will slow down, or even stop; the leaves will also become dull and lack luster. In summer, water should be increased appropriately, and the plant should be sprayed with water to keep the leaves green. During the winter dormancy period, watering should be further controlled to keep the pot soil relatively dry. Low temperatures and overly wet pot soil are not conducive to the plant's safe overwintering.
Fertilizing: Tolerates poor soil, with low growth requirements for fertilizer. Apply a balanced fertilizer of nitrogen, phosphorus, and potassium once a month to promote healthy plant growth and make the red-brown spines and beautiful patterns more vibrant. Fertilizing should follow the principle of "thin and frequent," avoiding thick fertilizers (which can damage the roots). After autumn, apply 1-2 times of phosphorus-potassium fertilizers, stop applying nitrogen fertilizers, which can help the plant overwinter safely. Fertilizing should be stopped during the winter dormancy period.
Pruning: If the basal leaves wither, they should be cut off promptly.
Repotting: Due to slow growth, repotting is not required frequently. Only when there are many suckers at the rootstock, repotting is necessary, usually once every 2-3 years. Repotting is best done in spring or early summer. During repotting, some old and rotten roots should be cut off, keeping the white new roots and replacing the soil with new one. Prefers fertile, loose, well-draining sandy loam soil with an appropriate amount of lime. The substrate can be prepared with materials such as decomposed leaf soil, garden soil, and coarse sand, and mixed with an appropriate amount of lime materials such as bone meal or shell powder. For valuable varieties like Princess Thor Variegata, it is best to use coarse-grained red jade soil (a type of planting soil native to Japan).
Disease and Pest Control: Affected by leaf spot disease, (T-J) disease, gray mold, and pests like scale insects and whiteflies.
