How should indoor plants be maintained?

1, water. For some shade plants, such as green radish, asparagus, Brazilian wood, evergreen and so on. They are generally fond of water and should be watered frequently, but there is a key point in watering: when the soil is dry, it will be watered thoroughly, that is, it will be soaked when it is dry. For some plants that like to dry, such as cactus, you can't water them often. If there is too much water, the roots will rot easily. 2. sunshine. Generally, plants placed indoors will choose shade plants, so they don't need much sunshine. If the sun is too strong, they won't grow well. Shade plants don't need sunlight, and everything needs sunlight, so they should be taken out occasionally to increase photosynthesis. However, it should be noted that cactus plants prefer sunshine, grow well in the case of sufficient sunlight, and see more sunshine. 3. temperature. Every plant has its optimum temperature, but the plants we often place have low temperature requirements, as long as they are neither too high nor too low, they are all suitable. In addition to delicate orchids, water, sunlight and temperature are very important for orchids to bloom. 4. Hydroponics. Hydroponics has great advantages: cleanliness, so hydroponics is very popular now. Any beautiful bottle, a plant and a few pebbles can show a good artistic effect, but hydroponics also has its key. A, change water frequently. If water is left for a long time, it will breed bacteria and smell bad, which is not conducive to root growth. B, you can supplement some nutrition. The nutrients contained in the water may not be suitable for the growth of plants or can not meet their growth requirements, so for some plants with higher growth environment requirements, some nutrients should be supplemented. But for some plants that are easy to raise, you can't add any nutrients, such as rich bamboo and green radish. (Note that there are many concentrated nutrient solutions on the market). C, there should not be too much water in the bottle. Roots need breathing. Once the oxygen contained in the water is consumed, the roots will breathe anaerobically, leading to root rot, which is the same as fish farming. So leave room for storing oxygen. In addition, several common planting methods (mainly from watering) are listed: 1. Aloe: Water: Aloe is more drought-resistant. Under normal circumstances, it is not a big problem not to water for ten days and a half. Although it affects the normal growth of aloe, it will not cause drought death. In contrast, due to excessive watering, the basin soil accumulated water for a long time, and the root system of Aloe vera was stunted by hypoxia, and finally turned black and necrotic, leading to the death of rotten heart. Therefore, we should master it flexibly according to the different growth and development stages and natural conditions of plants. If the ambient air humidity is high and the evaporation intensity is low, it is necessary to water less; If the air is dry, the temperature is high and the air circulation is strong, water it in time to prevent the basin soil and leaves from losing water too quickly. Do dry and wet alternately, dry and wet, and water reasonably. 2, cactus: cactus has four joys and four taboos: like dryness and avoid waterlogging, like light and shade, like sand and avoid sticking, like alkali and avoid acid, raising cactus, we must follow its growth law. 3, green radish: green radish is strong, can be potted indoors all year round, and placed in a sunny place in the basin for a long time. Green radish likes hot and humid environment, so it needs to spray water on leaves and ground frequently to keep the basin soil moist. 4. Wealth tree: the lowest temperature in winter is 16- 18℃, below which the leaves turn yellow and fall off; It is easy to die below 10℃. Nostoc flagelliforme is a strong positive plant, but it has strong tolerance to negative. You can enjoy it continuously in a place with weak indoor light for 2-4 weeks, and then put it in a place with strong light. Strong drought tolerance, it doesn't hurt if you don't water it for a few days. But don't drink water in the basin. Reduce watering in winter. During the growth period, you like high air humidity, and you can often spray a small amount of water on the leaves.
