How often should you water a cactus?
Today, the editor will introduce the knowledge about how often to water a cactus and the correct watering method for cacti in the field of green plants and flowers. Let's take a detailed look at how to water cacti appropriately!
Cacti are the most drought-resistant plants, and they generally thrive regardless of how they are cared for. However, some people still manage to kill their cacti, which can be quite不可思议. Usually, cacti are killed due to watering issues. Therefore, if you want to care for cacti well, watering is the key. Let's see how to water cacti appropriately!
One, the habits of cacti
Cacti originate from hot climates, so they are heat and drought-tolerant, prefer dry and warm environments, require plenty of sunlight, but do not tolerate waterlogging. Their tiny spines can help reduce transpiration during high temperatures, and their thick, fleshy leaves allow them to survive the hot summer. Therefore, theoretically, cacti do not need to be watered too much.
Two, how often should you water a cactus?
Cacti are easy to care for and do not require much water, but that doesn't mean they don't need water. Some people forget to water their cacti after buying them and just leave them aside. Although such cacti may still be alive, their appearance will not be good. Therefore, the correct watering frequency is about once every 20 days. If the potting soil dries out quickly, the time can be appropriately shortened to once every 10-15 days.
Three, how much water should you give a cactus?
In hot summers, with high temperatures and dry weather, cacti enter a dormant state. Watering them more at this time is useless as the cacti won't absorb the water and may rot instead. Therefore, water less in the summer, just keeping the potting soil slightly moist.
In the cold winter, you should start reducing watering when the temperature drops below 5°C, and then resume watering in the spring of the following year.
In spring, you can water thoroughly, watering the entire pot at once, but make sure there is no standing water, allowing it to grow fully.
In autumn, with dry weather and the potting soil drying out quickly, you can water thoroughly once every 10 to 15 days.
Four, what kind of water should you give a cactus?
How often should you water a cactus?
Cacti are not particular about the water they are given; ordinary tap water can meet their growth conditions. However, it is best to let tap water sit for 1-2 days before using it. If possible, collecting rainwater to water them can make them grow beautifully.
Five, why do cacti die from watering?
1. Overwatering can cause drowning
Cacti do not need frequent or excessive watering, as their roots are fine and numerous, and they are more suited to dry environments. If watered too frequently or too much, the roots may not absorb enough water, leaving standing water in the pot. Excess water can easily breed bacteria, causing root rot, and bacteria can enter through the rotting wound, leading to the death of the cactus.
2. Hot water can cause boiling
Never water cacti in the middle of the day when it is hot, especially when the temperature exceeds 30°C. This can cause the water to heat up and evaporate quickly, leading to a boiling effect on the roots, which can kill the cactus.
3. Cold water can cause freezing
