Cactus are generally considered to be a plant that likes to bask in the sun, but in fact, their needs for light are very special. If you don't understand the light needs of cactus, it will be difficult to maintain their healthy growth. This article will introduce in detail the light needs and precautions of cactus to help your cactus grow healthily.

Cactus's need for sunshine is different from other plants. Cactus grows in high temperature and drought environments in nature, so its need for sunshine is quite special. Unlike other plants, cacti do not need strong light and long periods of direct sunlight. They are better suited to growing in mild sunshine.
Different varieties of cactus have different light needs. Although most cactus have similar light needs, there are still differences between different varieties. For example, varieties such as golden cactus and cross cactus have a higher demand for sunlight and require more light.

Pay attention to avoid long-term exposure of cactus to strong sun. Because cactus's light needs are special, we need to pay attention to avoid exposing them to strong sun for a long time. If cactus is exposed to the sun for a long time, it will cause sunburn on its leaves, which will affect their healthy growth.
Adjusting the light time and intensity in different seasons and environments Since the light time and intensity vary in different seasons and environments, we need to adjust the light time and intensity of cactus according to different situations. In summer, when the sun is strong, we can place the cactus in a semi-shade to avoid excessive exposure to the sun. In winter, it is necessary to increase the light time to ensure normal growth.
Be careful to avoid sunburn caused by excessive fertilization. Excessive fertilization can also cause sunburn on cactus leaves. When fertilizing cactus, you need to pay attention to appropriate amounts to avoid excessive fertilization.
The

often turns the cactus to ensure uniform light. Since the sun will directly fall from one direction, if the cactus is not turned frequently, some parts will be exposed to the sun for a long time, while other parts will lack light. We need to turn the cactus frequently to ensure that its leaves receive sunlight evenly.
Avoid excessive evaporation of water causing sunburn Excessive evaporation of water can also cause sunburn on cactus leaves. In the hot summer weather, we need to pay attention to avoid excessive spraying to prevent excessive evaporation of water.
Choose the appropriate cultivation site and container In order to ensure the healthy growth of cactus, we need to choose the appropriate cultivation site and container. When selecting a cultivation site, we need to consider factors such as sunlight, temperature, humidity, etc.; when selecting a container, we need to consider factors such as container size and material.
Be careful to avoid exposing cactus to a dark and humid environment for a long time. Cactus is a plant that likes to dry. Long-term exposure to a dark and humid environment can cause their health to deteriorate. When cultivating cactus, we need to be careful to avoid exposing them to dark and humid environments for long periods of time.
Avoid sudden changes in the light environment Sudden changes in the light environment of cactus can also affect their health. When adjusting the lighting environment of cactus, it needs to be done step by step to avoid sudden changes.
Pay attention to avoid contact between cactus leaves and windows. Cactus leaves contacting the window glass for a long time may cause sunburn on the leaves, so we need to pay attention to avoid contact between cactus leaves and windows.
Using soil with better air permeability Using soil with better air permeability can increase the ventilation of cactus roots and increase its growth rate.
Adjust the light intensity by observing the color of cactus leaves. The color of cactus leaves can also tell us whether we need to adjust the light intensity. If the cactus leaves are yellow, it means they need more sunlight.
Be careful to avoid sunburn caused by excessive irrigation. Excessive irrigation can also cause sunburn on cactus leaves. When watering, you need to pay attention to the right amount to avoid excessive watering.
Through the introduction of this article, we learned about the special needs and precautions of cactus for light. Only by understanding and meeting these needs and precautions can we let our cactus grow healthily.
