Cacti watering
This article explains the knowledge about succulent plants for concerned netizens, such as watering cacti. Next, the editor of this site will introduce to you.
This article is a summary of the watering method of cacti by a flower enthusiast based on their own habits. For新手 cacti growers, it can help them understand how to water cacti without having to explore step by step.
Water: Generally, use tap water that has been placed in a non-transparent plastic bucket for one day, and it should not be kept for too long (the microorganisms in the tap water, together with the light transmission of transparent or semi-transparent buckets, can easily breed brown algae) or water directly with fresh tap water (the tap water quality in Beihai is acceptable, but it varies from place to place. Enthusiasts can filter or distill it).
Watering tools: Use a watering can with gentle water flow and appropriate water output to avoid messing up the soil surface. Fresh tap water can be sprayed directly using a hose with a spray head, usually in SHOWR and CENTER mode (the silver-black spray head in the picture has excellent water output and softness, highly recommended).
Watering time: The best time is in the morning on sunny days in spring, summer, and autumn, or in the evening. It is not suitable to water at noon when the potting soil is too hot; in winter, it is generally in the morning or at noon. It is also not suitable to water at night when the temperature is slightly lower. The prerequisite is that the weather will be continuously sunny and good, if it will be cloudy and rainy, it is better not to water even if it is completely dry. (I started watering around 10 o'clock this morning, a bit later)
Watering method: It is usually watered thoroughly when it is almost dry (not completely dry in the true sense), pouring directly from the top of the cactus, basically not soaking the pot. Many flower enthusiasts soak the pot when growing cacti, afraid to water from the top, worrying about the dirt on the hair, the injury to the ball, and rust spots. However, this often backfires, and the cacti end up being dirtier. If only the soaking method is used, over time, more or less dust will stick to the cactus hair, along with bacteria and fungi, accumulating and making it dirty over time. By watering from the top as a routine, there is basically no chance for dust to attach, and since there is little dust in the greenhouse, the cactus hair remains clean. This logic seems simple, but many people are reluctant to try...
PS: Such watering also requires certain prerequisites, such as good water quality, sunny weather, proper shading, and ventilation... so that the water on the cactus can evaporate quickly while ensuring that the cactus is not burned. Also, a few varieties, such as some ISW系列 white cacti, may be affected by this watering method in terms of the fluffiness of the white spots, but most other varieties do not have significant adverse effects. Some people worry that this watering method will cause the hair to turn yellow, but after many years of practice, I would not blame the yellowing on this watering method. Instead, more consideration is given to other comprehensive factors such as air quality and light intensity.
This is just the watering method I adopt based on my own environment, for reference only. It is important to adapt to local conditions when growing cacti. It's not easy to grow cacti; start learning while playing, starting with watering...
The above is a detailed explanation of watering cacti. I hope this article can help you with green plant management!
