Hard water refers to water with a higher concentration of calcium and magnesium ions, which can easily form scale in the roots of potted plants during irrigation, hindering the absorption of water and nutrients by the plants. Long-term irrigation with hard water can lead to slow growth or even death of potted plants.
Preventive measures:
1. Use softened water to irrigate potted plants, such as boiled and cooled water or purified water.
2. Before irrigation, you can fill a container with water, let it sit for a while to allow the calcium and magnesium ions to precipitate, and then use it to water the potted plants.
Cold water kills potted plantsCold water is detrimental to the growth of potted plants because the plant roots are sensitive to temperature. After being irrigated with cold water, the roots will be stimulated, leading to root damage or even death.
Preventive measures:
1. Use water with a temperature close to room temperature to irrigate potted plants.
2. Before irrigation, you can let the water sit for a while to gradually bring the water temperature close to room temperature.
Hot water kills potted plantsHot water can scald the roots of potted plants, causing root damage and affecting the normal growth of the plant. The chlorine and other harmful substances in hot water can also harm potted plants.
Preventive measures:
1. Use warm water to irrigate potted plants, and the water temperature should not be too high.
2. Before irrigation, you can boil the water first and then let it cool before using it to water the potted plants.
Repeated watering kills potted plantsSome people like to water their potted plants frequently, believing that it will help the plants grow better. Frequent watering can lead to oxygen deprivation in the roots of the plants, causing them to die.
Preventive measures:
1. Arrange the watering schedule according to the type and growth stage of the potted plant.
2. Observe the soil moisture of the potted plant, and water only when the surface of the soil appears dry.
Not watering thoroughly kills potted plantsSome people only water the roots of the potted plant and do not thoroughly water the entire soil layer, which can lead to the plant's roots being unable to fully absorb water and nutrients, causing death.
Preventive measures:
1. When watering, try to thoroughly water the entire soil layer.
2. Use a spray bottle or watering can to evenly water from top to bottom.
Understanding what kind of water kills potted plants is crucial for their maintenance. When irrigating potted plants, avoid the fatal watering mistakes such as using hard water, cold water, hot water, frequent watering, and not watering thoroughly. Only by mastering the correct watering method can potted plants grow healthily.References:
