1. The temperature should not exceed 25℃, otherwise it will stop growing and go into dormancy, resulting in yellowing and withering of buds.
2. Sufficient sunshine, otherwise the leaves will grow into garlic leaves;
3. The water used should be clean, otherwise it will cause pollution and root rot due to the deterioration of water quality.
Narcissus has special growth characteristics, and its flowering date can be decided by people themselves. If flowers are required to bloom during the Spring Festival, bulbs (narcissus heads) can be planted in pots about 20-300 days before the Spring Festival, and then they will start to grow until they bloom. The optimum growth temperature of Clivia is 15-25℃. It is not hardy in winter, and it is dormant when the room temperature is lower than 10℃. I like growing in a semi-cloudy environment, but I'm afraid of direct sunlight. Clivia's fleshy roots and thick leaves can store a certain amount of water, so it is generally not advisable to water too much. It is advisable to keep the basin soil dry and wet during the growing period. Water should be properly controlled in summer, otherwise the leaves will grow in vain. If the water in the basin is hot and humid for a long time, it will also cause root rot and dry up the leaves above. When the climate is hot and dry, you can often spray water on the leaves and underground to avoid burning the leaves. In the growing season, we like fertilizer. In addition to applying base fertilizer to fat cake fertilizer or decomposed manure when changing pots, dry fertilizer should be applied once every spring and autumn, and decomposed light liquid fertilizer should be applied once every 15-20 days. Pot soil can be mixed with 80% horse manure or humus soil and 20% yellow sand. When changing pots, gently knock out the plants from the original pots, shake off the old soil, remove the rotten roots and plant them in pots filled with new culture soil. When planting, if the root system is long, it can be put into a pot, and the fleshy root should not be short. Water immediately after changing pots, so that the soil and roots can be closely combined.
There are two methods for propagation of Clivia: sowing and rameting. Clivia, which is sown and propagated, generally needs to grow for 4-5 years, and the leaves can only bloom when they grow to more than 25. The method of ramet propagation is to break off the ramets around the mother plant by hand or cut them off with a sharp knife when changing pots. It is best to bring some roots, plant them in sandy loam without fertilizer and water them. After the new roots are born and the plants begin to grow, the Clivia culture soil can grow vigorously, and it can bloom after three or four years of growth. Aloe vera has strong vitality and is easy to cultivate. In the process of its growth, it has the characteristics of liking sunshine, fearing scorching sun, being warm and humid, avoiding water accumulation, resisting high temperature and cold. According to these characteristics, it is necessary to master the requirements of light, moisture, temperature and soil during the growth of aloe, and create an environment suitable for the growth of aloe, so as to cultivate aloe well. Current management
First, water the aloe basin soil to keep it moist. Too much water is not good for the root system of aloe, because aloe has the characteristics of drought tolerance and fear of waterlogging. When watering is needed, gently water along the edge of the basin, and don't wash it hard, so as to avoid the soil hardening easily and affect the permeability of the soil. After the basin soil is hardened, loosen the soil in time to a depth of about 1.5 cm.
2. Fertilizing Aloe vera in the growth process, it is not enough to rely only on the nutrients in the basin soil. Proper fertilization can meet the growth needs. Organic fertilizer, such as peanut bran (cake), is better, more efficient and cleaner. Before use, fully soak in water for fermentation, and then dilute with water. For example, apply a chemical fertilizer with a concentration of 0. 1%. The frequency of fertilization depends on the growth of aloe. If you use leaves frequently, the frequency should be more, about once a month. 3. Potted soil suitable for growth should have the functions of fertilizer conservation, water conservation, drainage and ventilation. The pH value should be neutral. The hometown of cactus is in South America, which is native to the desert with high heat, dryness and little rain, and has formed the characteristics of being dry-loving, drought-resistant and cold-resistant. Below 5℃, it is possible to freeze to death, most varieties will change color, and if it is lower, it may freeze to death. Xianrenqiu management
1, give the root a larger breathing space, so that it is not easy to rot;
2. Cultivate in sandy loam and fertilize once every twenty days until the beginning of October;
3. The principle of watering is not to dry, but to pour thoroughly; Don't water too much, and don't water for a long time.
4. Move it indoors to 8 degrees in winter. If it is a triangular arrow, put it indoors above 12 degrees. Crab claw orchids are native to tropical rainforests such as Brazil and Mexico. I like warm, humid and semi-cloudy environment, and can be cultivated indoors all year round. There should be enough light from the pregnant bud in autumn to the flowering period in the following spring, and it is best to plant it in a sunny place by the window. Avoid sun and rain in summer, put it in a well-ventilated place or move it to the outdoor semi-shade, requiring fertile sandy loam with good ventilation and water permeability.
In the usual management and maintenance, we should always keep the basin soil moist, water it as soon as it is dry, and often topdress it, especially the decomposed light liquid fertilizer once a week from germination to flowering. If it is cultivated outdoors in summer, it will be cultivated indoors in the sun after it is cool in autumn. In winter, the indoor temperature is kept at 15-20℃, and the plants are often washed with water to keep them bright green. According to the growth of plants, change flowerpots in time. It is better to change pots than to see flowers in spring. Potted soil can be mixed with 30% humus soil, 20% garden soil, 40% yellow sand and 1% decomposed manure. When changing the pot. 5-6 pieces of horseshoe or cow hoof are placed at the bottom of the basin as base fertilizer. Water every time after changing pots, so that the soil and plant roots are closely connected. Rose, alias Catharanthus roseus, Moon Red, Four Seasons Rose, etc. It belongs to Rosaceae, an evergreen shrub. Originated in Jiangsu, Zhejiang, Shandong, Hebei and other places in China, it is now cultivated in all provinces. Rose has strong adaptability to the environment, likes warm and cool climate and sufficient sunshine, and is drought-resistant and cold-resistant. Rose is a native variety in China, which has been cultivated for thousands of years. Rose is a thorny shrub, or it is tendril-like and climbing. I like sunny, airy, well-drained and sheltered environment, and I need proper shade in midsummer. The optimum temperature of most varieties is 15 ~ 26℃ in the daytime and 10 ~ 15℃ at night. It is cold-resistant, and it goes into hibernation when the temperature is below 5℃ in winter. If the high temperature lasts above 30℃ in summer, the flowering and quality of most varieties will decrease, and they will enter semi-dormancy period. Common varieties can withstand the low temperature of 65438 05℃. It needs rich organic matter and fertile and loose slightly acidic soil, but it has wide adaptability to soil. The relative humidity of air should be 75% ~ 80%, but it can also be slightly dry or slightly wet. Characterized by continuous flowering.
Propagation and cultivation
Propagation is mainly based on grafting and cutting, supplemented by sowing and tissue culture.
