Captain 80 soil 丨 Autumn you have to know the succulent watering precautions ~
Watering more during the dormant period can easily lead to plant rot. For example, if dormant raw stone flowers are watered in the summer, the plants will rot immediately. If dormant cacti are watered in winter, they can cause root rot or be susceptible to freezing. While winter may not rot, it will rot in spring. The best way to water succulents is to water them according to the state of the soil. Because most succulents prefer slightly wet soils without stagnant water, they can be watered as soon as the soil dries out. When pouring, you need to use pure water without impurities. Every time you water, water the flower soil thoroughly.
To carefully observe the growth of each plant, some people see red leaves, dry tips, old leaves and think that some plants are dehydrated. In fact, the light is too strong, the pot soil is long-term lack of water, the root system is destroyed, the root neck is rotten, and the root neck is automatically repaired after being bitten by insects, resulting in poor water transportation. Therefore, being familiar with the growth of plants is very helpful for mastering watering techniques. Plants that generally grow particularly vigorously and plants in the flowering and gestational bud stages have relatively high requirements for water, and should be watered as much as possible in time; And some old bulbs that are essentially stagnant should be watered less often.
Watering should consider the temperature, air humidity, greenhouse ventilation, the size and material of the basin, whether the root system extends downward to the sand bed, etc. The purpose is to help determine if there is a shortage of water in the pot. In other potted flower cultivation, it is generally possible to decide whether to water the pot soil according to whether it is white, but in succulents, this judgment will lead to errors, because the cultivation soil of succulents is generally mixed with sand, vermiculite, light stone, shell powder and other substances, which is easy to cause the surface of the pot soil to be white. Especially in the case of a large proportion of these substances, the surface of the pot soil is white the day after watering, and then the pot soil below is not short of water at all. Some experts pointed out that when the surface of the pot soil is dry by 1 cm and the bottom pot soil is still wet, the absorption of succulent roots reaches the maximum. If the potted soil is watered as soon as it turns white, it will cause too much watering and affect plant growth.
The watering time is early in the morning in summer, before noon on a sunny day in winter, and in both morning and evening in spring and autumn. Under normal circumstances, do not pour water from above, otherwise there will be unsightly spots on the accumulated spheres over time, and the hairs of the hair column are easily contaminated and bonded, and the accumulation of water at the palm of the jade flower will cause decay. The water of the pond is easy to grow algae on the plants and is as ugly as moss. In general, watering must use a sufficient amount of water. Therefore, it is necessary to loosen the soil frequently so that the potting soil can easily absorb enough water evenly. For growing winter plants and intermediate plants, the potted soil should be kept moist, not waterlogged, watered thoroughly, not watered, and not too dry. Summer seeds can be watered properly, but not in excess. In case of rain or a sudden drop in temperature, watering should be stopped.
How to control the amount of watering: Bamboo skewer judgment: that is, bamboo skewers (or toothpicks) inserted into two-thirds of the depth of the potting soil. When watering, pull out the bamboo skewers and look at the dry moisture of the soil. This method helps to irrigate dormant and semi-dormant plants or plants that enter the dormant and semi-dormant periods.
Topsoil wet and dry judgment method: In general, when the topsoil turns white, it can be watered. This is the principle of "do not dry, dry, pour thoroughly". The so-called dry, that is, the topsoil is white, but the water can be seen when the topsoil is removed. For the growth period of fairy meat, this method of judgment is sufficient. Those with strong habits can be watered immediately, and those who are relatively afraid of water can wait for two days to water again.
The end pot method is to feel good friends, feel light can serve the pot to pour water. Fairy meat grown in plastic pots and lightweight materials such as soil and carbon are mainly used in soil. After watering and drying, the amount is still obvious. The potting method, that is, tapping the basin wall with your fingers, makes a hollow sound, indicating that the soil is dry.
Sitting in the basin is the best way. In general, it takes only 15 seconds for the basin to dip into half the water depth, so don't take it out when moisture appears in the topsoil. The looser the soil, the more breathable it takes, and the less time it takes because of the strong siphon effect. The advantage of this watering method is that it can ensure that the upper part of the soil is relatively dry than the lower part, and it is not easy to rot the roots. Because the root tip of the plant is divided into root crown area, growth area, growth area and root hair area, only the root hair is the main part of absorbing water, the strongest moisture resistance, and the old root above the root hair area has lost the water absorption function, mainly playing the role of water transport, nourishment and fixation, and the moisture resistance is poor. Root rot often starts here.
