Clivia has been planted in my home for 20 years, and its roots are already very thin. How to maintain it?

Clivia is suitable for indoor cultivation, which is mainly determined by its internal structure and physiological function. Clivia is an evergreen perennial herb with strong shade tolerance and thick dark green leaves. There are a lot of chlorophyll in mesophyll, which can absorb carbon dioxide and water in sunlight, synthesize organic matter for its own growth and development, and release oxygen at the same time. In addition, Clivia leaves grow many pores and fluff, which can secrete a lot of mucus, and in the process of gas exchange, it can absorb a lot of indoor dust, dust and harmful gases to make the indoor air clean, so Clivia is also called "absorber" and "dust collector", which is the patron saint of human health. So how do you make this healthy protector grow up healthily in your home? The family maintenance of Clivia should mainly start from the aspects of temperature and humidity, soil, moisture, light and nutrition.

Because Clivia originated in the mountains of South Africa, where the natural environment is like spring all the year round, all organs of Clivia plants have adapted to this lukewarm natural environment. Therefore, in the process of daily maintenance, the temperature should be controlled between 15-25 degrees. When the temperature drops below 10, Clivia grows slowly, and it will freeze to death when it drops below 0. Similarly, when the temperature reaches or exceeds 30 degrees, it will also seriously affect the normal growth and development of Clivia.

Water is an important part of Clivia. According to the determination, Clivia contains 60%-80% water, especially its fleshy roots have strong water storage function and strong drought resistance. Clivia likes neutral water. Clean and pollution-free tap water, well water and river water can be used for irrigation. However, because the water temperature of fresh tap water and well water is lower than the soil temperature and contains some impurities, they should be placed for 1-2 days before use. As for watering, there are also many stresses. For Clivia seedlings, the best way is to spray irrigation with a watering can. Spraying the nozzle upward on the leaves has the advantages of watering the flowers and washing away the dust. At the same time, fog beads are left on the leaves to ensure a certain humidity of the leaves. Evaporating water in the sun can reduce the surface temperature of leaves and prevent sunburn. However, the flowering Clivia can't be watered by sprinkler irrigation to prevent water from entering the leaf sheath and causing rotten hearts. For flowering Clivia, you can only pour water into the basin. When and how much water is appropriate? This mainly depends on the ambient temperature of Clivia. The general principle of watering is "see wet and dry, don't do it, water it thoroughly." Soaking means that all the roots of Clivia are under the same humidity. To judge whether the water is completely poured, we can't just determine whether there is water flowing out of the basin bottom. Because sometimes the soil in the basin will harden and shrink into a ball when it dries, and water will soon flow from the basin wall to the bottom and drip out from the bottom hole after watering. The central part of the basin soil doesn't even touch any water. If you stop watering at this time, Clivia's leaves will wither and form an arrow when it shoots an arrow. Here is a simple and effective watering method, that is, soak all flower pots in a basin or bucket filled with water for half a minute before taking them out. However, the disadvantage of this is that the nutrients in the soil are easy to lose, so in order to make Clivia have deep roots and large leaves, we should pay attention to replenish nutrients to it in time. The nutrients needed by Clivia mainly come from organic fertilizer, such as bean cake, peanut oil cake, animal offal and so on. Under normal circumstances, it can be applied in spring and autumn within one year. Apply 1 time in spring at the end of April and the beginning of May after flowering; After the autumn fruit is harvested, it should be applied again from the middle of September to the end of 10.

Clivia is a wet plant, and its growing environment needs high humidity. Its optimum humidity range is 70%-80%. Clivia grown in this environment has green leaves, clear veins, short, wide and tidy leaves and high ornamental value. However, due to the family environment, it is difficult for ordinary families to meet this standard. This is also the main reason why many people can't raise Clivia. Clivia is a medium-sunshine plant, and its light requirement is not strict. As long as the temperature is suitable, the illumination time can be long or short, and short sunshine in winter and spring is more conducive to flowering. Good illumination is an important condition to ensure the bright color of Junzi Orchid. But it still likes weak light, especially strong light.

Clivia leaves have phototaxis. If left indoors for a long time, the leaves will definitely deflect in the direction of the sun. As far as its plant modeling is concerned, it is difficult to achieve the ornamental effect of looking at a line from the side and looking up like a fan.

Clivia must be placed in the north-south direction, not in the north-south direction. What if the leaves are too long? You can clip two leaves together and surround them with playing cards to avoid hurting them. If it is normal, the leaves will be corrected in 15-20 days.

Clivia's stout fleshy roots not only store enough water, but also put forward higher requirements for the soil on which it depends. Only nutrient soil with good air permeability, loose texture and rich humus is suitable for the growth of succulent roots of Clivia.

Anti-rot leaves or loose hair must be fermented before use. Without fermentation, roots burn easily. Clivia must change the soil once a year.

The time and frequency of soil replacement of Clivia depends on the size and season of seedlings. Like these mature clivia, they have to change the soil once a year. The best time to change soil is spring and autumn, because Clivia grows vigorously at this time, and the growth of plants will not be affected by changing soil. Take Clivia out of the pot, cut off rotten roots and old roots that have no absorption ability, and remove waste soil. Cover the drain hole of the flowerpot with broken pots, fill it with nutrient soil with a thickness of 2-5cm, grab a handful of soil and fill it in the roots, then put the plants into the pot. When the nutrient soil is filled to half the height of the pot, gently press it down along the edge of the pot with your hands, so that the roots stand in the pot and are not easy to bend. The key point of soil replacement is to fill the roots with soil. Otherwise, there is no soil at the root, and water and nutrients cannot reach the root, which is easy to cause rotten roots and arrows. After changing the nutrient soil, you can water it.

In fact, in the final analysis, Clivia's conservation knowledge is far more than that. Many conservation knowledge depends on the exploration and accumulation of orchid growers in practice. But you don't have to worry, because many clivia lovers also know that it is difficult to raise clivia well, but it is not easy to raise clivia to death. Although this is a joke, it also shows that Clivia is not so delicate. As long as you work hard and pay more attention, you can certainly cultivate colorful Clivia, and life can naturally add a little beauty and fun.
