1. Water. For some shade plants, such as pothos, asparagus, brazil wood, dieffenbachia, etc., they generally like water and need to be watered frequently, but there is a key point for watering: see dry and wet, water thoroughly when dry, that is, wait for soil Water when dry. Once watered, wet the soil. For some plants that like dryness, such as cacti, they cannot be watered frequently. Too much water will easily cause root rot. 2. Sunshine. Generally, plants placed indoors will choose shade plants. They do not need too much sunlight. Too strong sunlight will cause poor growth. Shade plants do not need sunlight. All things need sunlight, so they should be taken out in the sun occasionally to increase their photosynthesis. However, note that cactus plants prefer sunlight. In conditions with sufficient light, they do not need sunlight. They grow well in the sun, so give them plenty of sunlight. 3. Temperature. Each plant has its most suitable temperature, but the plants we often place do not have high temperature requirements. As long as it is not too high or too low, they are suitable. Except for delicate orchids, if you want orchids to bloom, the three elements of water, sunlight, and temperature are very important. 4. Hydroponics. Hydroponics has great benefits: it is clean, so hydroponics is very popular nowadays. Any beautiful bottle, a plant inserted, and a few pebbles can show a good artistic effect, but hydroponics also has its key points. A. Change the water frequently. If the water is left for a long time, bacteria will breed and cause a smell, which is not conducive to root growth. B. You can add some nutrients. The nutrients contained in the water may not be suitable for the growth of plants, or may not meet their growth requirements, so for some plants with higher growth environment requirements, some nutrients must be added. But for some plants that are easy to grow, no nutrients are needed, such as lucky bamboo, pothos, etc. (Note, there are many concentrated nutrient solutions on the market). C. There should not be too much water in the bottle. Roots need to breathe. Once the oxygen contained in the water is consumed, the roots will undergo anaerobic respiration, leading to root rot. This is the same as raising fish. Therefore, leave space for storing oxygen. In addition, the planting methods of several common plants are listed (mainly from the aspect of watering): 1. Aloe vera: Watering: Aloe vera is relatively drought-resistant. Under normal circumstances, if it is not watered for ten days and a half, the problem will not be big, although it will affect the aloe vera. Normal amount of growth, but will not cause drought mortality. In contrast, due to excessive watering, the pot soil accumulates water for a long time, and the aloe vera root system is stunted due to lack of oxygen, and eventually turns black and necrotic and causes heart rot and death. Therefore, it is necessary to flexibly control according to the different growth and development stages of plants and natural conditions. If the surrounding air humidity is high and the evaporation intensity is low, water less; if the air is dry, the temperature is high, and the air circulation is strong, water must be timely to prevent pot soil and the leaves lose water too quickly. Make sure to see dry and wet, water thoroughly when dry, and water properly. 2. Cactus: Cactus has four likes and four taboos: it likes dryness and avoids waterlogging, likes light and shade, likes sand and avoids stickiness, and likes alkalis and avoids acid. To raise a cactus well, you must follow its growth rules. 3. Pothos: Pothos is strong and can be grown indoors all year round. It can be placed in a pot in a sunny place for a long time. Pothos likes a hot and humid environment, so it needs to spray water on the leaves and ground frequently and keep the pot soil moist. 4. Money tree: The lowest temperature in winter is 16-18°C. Below this temperature, the leaves turn yellow and fall off; below 10°C, it is easy to die. The money tree is a strong positive plant, but the plant has strong shade tolerance. It can be enjoyed indoors in a place with weak light for 2-4 weeks, and then placed in a place with strong light. It has strong drought tolerance and will not be harmed if it is not watered for several days. But avoid water accumulation in the basin. Reduce watering in winter. It likes high air humidity during the growth period, so you can spray a small amount of water on the leaves from time to time.
