How to grow Graptopetalum paraguayense (moonstone succulent)? A detailed guide to the latest cultivation methods
Graptopetalum paraguayense is one of the succulent plants introduced to China relatively early, also known as jewel flower, stone lotus, etc. It is a perennial evergreen subshrub of the genus Graptopetalum in the Crassulaceae family. Its plant form is relatively looser than other varieties of the same genus. Because of its strong vitality, rapid growth, and easy propagation, it is widely cultivated throughout China. Let us take a look together at the cultivation methods for Graptopetalum paraguayense!
Growth habits of Graptopetalum paraguayense
Graptopetalum paraguayense likes plenty of sunlight, dislikes waterlogging, tolerates poor soil, and is best grown in well-drained sandy loam. Long-term insufficient light will cause the stem nodes to elongate, and the leaves to become small and sparse, losing ornamental value. In the spring and summer growing seasons, watering once or twice a week is sufficient. In autumn and winter, the amount of watering should be controlled according to the cultivation environment temperature. When the temperature is above 15°C, water once every two weeks. When it is below 10°C, keep the potting soil dry and basically stop watering.
Propagation methods of Graptopetalum paraguayense
Graptopetalum paraguayense is mostly propagated by cuttings. During the growing season, stem cuttings can be taken along with pruning. Leaf cuttings can also be used. Place the leaves flat on moist plain sandy soil. After two weeks, multiple adventitious buds and adventitious roots can be seen differentiating near the leaf veins at the base of the leaves. When doing leaf cuttings, the cutting bed should not be too wet, otherwise the leaves are prone to rot.
Cultivation methods of Graptopetalum paraguayense
1. Light: The more sufficient the light and the greater the temperature difference between day and night, the more vivid and glossy the leaf color. When the temperature is suitable, it is best to place it outdoors for care to ensure sufficient light. When light is insufficient or soil moisture is excessive, it will grow leggy, the whole plant will become dull and green, the leaves will be sparse and the spacing will elongate, accelerating upward growth, seriously affecting its ornamental value, and it may even die because the plant's photosynthesis is hindered.
2. Water: Because the plant has a high internal water content, Graptopetalum paraguayense is prone to rot in an overly humid environment. Never water too much. To avoid water accumulating at the roots, it is best to choose a pot with drainage holes at the bottom. Beginners can use well-aerated red clay pots. Glass containers absorb heat and have poor breathability, so use them with caution. Water about once every 10 days, and just water thoroughly each time. The watering frequency can be increased or decreased as appropriate according to climate differences in different regions and seasons.
3. Soil: It is best to cultivate it in sandy soil with good drainage and aeration, so as to facilitate the discharge of excess water and the growth of the plant's roots. It can be prepared with 1 part each of pine needle soil, vermiculite, leaf mold, and sandy soil. Repot once every 1 to 2 years in spring. Dead old roots and overly lignified stems can be cut off to avoid affecting the plant's normal growth and water absorption.
4. Temperature: Under normal circumstances, growth stops or mild frost damage occurs below 5°C, and at 0°C and below, the water in the leaves freezes and the cells die. When the temperature is too high (above 35°C) or too low (below 5°C) in winter and summer, the plant stops growing. At this time, watering should be temporarily reduced or stopped, and the watering frequency should be resumed when the temperature is suitable. During high summer temperatures, pay attention to ventilation and prevent long periods of direct sun exposure to avoid sunburn.
5. Pruning: Usually, dry and dead old leaves need to be removed promptly to prevent accumulation from causing bacterial growth. When the plant grows leggy or too tall, the top branches and leaves can be pruned to shape it and control the plant height, so as to maintain a beautiful plant form. The cut top part can be dried until the wound heals and then inserted into slightly moist sandy potting soil to take root and become a new plant. The stems and branches at the bottom can sprout more side buds.
