Correct Method for Cultivating Kalanchoe
Today, let's delve into the related content of the correct method for cultivating Kalanchoe. This is a great piece of knowledge that is worth collecting!
1. Soil: For potted plants, it is advisable to use a mixture of fertile garden soil, decomposed leaf mold, and river sand in a ratio of 1:2:1. Adding a small amount of bone meal can enhance the mixture. When the seedlings grow to 10 centimeters, it's necessary to pinch back 1-2 times to promote the growth of lateral buds and help the plant take shape quickly.
2. Light: During the growing season, except for the midsummer when shading is required to maintain 60% light transmission, normal lighting is sufficient for other seasons. Avoid excessive shade, as it can easily lead to elongated branches and a loose plant structure. During the growth of Kalanchoe, it is necessary to regularly rotate the pot to adjust the light position, ensuring even exposure and promoting balanced growth in all directions.
3. Watering: Kalanchoe is different from other plants; it contains more water and is more drought-resistant. Therefore, do not overwater during the growing season, keeping the potting soil slightly dry. Water only when the soil is completely dry, usually every 3-4 days; in dry weather, you can spray water around the plant to increase humidity.
4. Fertilizing: Fertilizing for Kalanchoe should be done during the spring and autumn growing seasons and after flowering. Generally, a dilute liquid fertilizer can be applied every 15-20 days, or a slow-release fertilizer can be applied on the surface of the potting soil, both of which can promote robust plant growth and abundant flowering. To encourage more flowers, brighter colors, and a longer flowering period, you can apply 0.2% potassium dihydrogen phosphate solution 1-2 times after the flower buds have formed to increase the potassium content. Fertilizing should be stopped in winter.
5. Pruning: To cultivate Kalanchoe well, pruning is essential. During the peak growing season, it is necessary to pinch back the plants to promote branching and make the pot plants grow more fully. After the flowers fade, promptly remove the残花 to avoid consuming too much nutrients, which can affect the quality of the next flowering.
6. Precautions: Kalanchoe is a succulent plant that does not like too much water. It's best to water before noon, ensuring the leaves are dry before it gets dark. The water should be slightly acidic and not have a high salt content.
