Why Is My Cactus Turning Light Green

Not Enough Sun Light

Cacti need sunlight to create food for themselves through photosynthesis, but too much sun can damage them.
If your cactus is in too much sun, it will start to turn a light green color as a way to protect itself from the intense heat and light.
Cacti can also change color if the sunlight is not enough. If your cactus isn’t getting enough sun, it will start to stretch out and turn a light green color in an attempt to get more sunlight.
The light green color is the cactus’ way of telling you that it’s not getting the right amount of sun.


The best course of action is to let in just the right amount of natural light.
About six hours of bright, indirect sunshine per day is ideal for a cactus. Put it in a spot with some shade but still plenty of bright, indirect light, and it should recover.

Inadequate Watering

Cacti are succulents, which means they store water in their leaves and stems.
This allows them to survive in hot, dry conditions where other plants would wilt and die. However, even cacti need some water to survive.
If you don’t water your cactus enough, it will start to turn a light green color as a way to conserve water. The light green color is the plant’s way of telling you that it’s stressed and needs more water.
On the other hand, can also cause your cactus to turn light green. If you water your cactus too much, the roots will start to rot and the plant will turn a light green color as it tries to save itself.
The light green color is the plant’s way of telling you that it’s in danger of dying and needs help.


The best way to water a cactus is to let the soil dry out completely between watering. Water deeply, then allow the plant to dry out completely before watering again.
This will help prevent root rot and ensure your plant gets the water it needs without drowning it.

Inadequate NutrientSupply

To thrive, cacti require a steady supply of macro-nutrients like nitrogen, magnesium, and phosphorus. If the cactus doesn’t get enough of the right minerals, its skin will fade to a pale green and it will wilt.
It typically occurs when root rot prevents a plant from taking in the necessary minerals. The cactus’s hue will fade if the soil it’s put in lacks minerals.


The easiest technique to treat a cactus with rotting roots is to cut the problematic roots and then apply an efficient fungicide to the plant.
The cactus should be repotted into new, nutrient-rich soil if the current soil is inadequate in any way. Until the cactus’ original color returns, it should be supplied with nutrient-rich fertilizer at regular intervals.

Temperature Stress

Cacti are native to hot, dry climates, so they’re not used to cold temperatures. If the temperature drops too much, the plant will start to turn a light green color as a way to protect itself from the cold.
The light green color is the plant’s way of telling you that it’s not happy with the temperature and needs to be in a warmer environment.


The best way to protect your cactus from temperature stress is to keep it in a warm, sunny spot. If the temperature drops too much, you can move the plant indoors or put it in a greenhouse.


Cacti are severely damaged by pests that feed on the plant’s sap, such as scales, red spiders, and mealybugs. The plant wilts and turns a pale green as a result of this.


The spread of the pests can be stopped if the infected plant is quickly isolated. At regular intervals, spray the plant with an efficient insecticide or rubbing alcohol until the pest is no longer a problem.
Only after making sure the bug is completely gone may the cactus be reintroduced to other plants.


Cacti can also be affected by diseases, such as root rot and fungal infections. These diseases can cause the plant to turn a light green color as the plant struggles to stay alive.
The light green color is the plant’s way of telling you that it’s sick and needs to be treated.


The best way to prevent diseases from affecting your cactus is to make sure the plant is in well-draining soil.
This will help prevent the roots from rotting. If the plant does get sick, you can treat it with a fungicide or insecticide.


Cacti need a lot of sunlight, little water, and well-draining soil to thrive. If your cactus is turning light green, it’s a sign that something is wrong.
The most common causes are over-watering, under-watering, pests, diseases, and temperature stress. By following the solutions in this article, you can help your cactus get back to its original color in no time.
