In fact, the change in color could be an indication of the plant’s overall health and may even be a part of its natural growth process. So, relax, grab a cup of tea, and let’s delve into the intriguing world of jade plant color changes.
I. Possible reasons for color change in a jade plant
A. Exposure to direct sunlight
One possible reason for a color change in your jade plant could be its exposure to direct sunlight. While jade plants do need some sunlight to grow, excessive amounts can lead to changes in their color. If your plant is receiving too much sunlight, it may develop increased pigmentation or a purple or reddish tint. In extreme cases, prolonged exposure to direct sunlight can even cause sunburn damage, resulting in burnt or brown spots on the leaves.
B. Insufficient light
On the other hand, if your jade plant is not receiving enough light, it may also experience a color change. Insufficient light can cause the plant to stretch or elongate its growth as it tries to reach for more light. The leaves may become pale or yellow, and there may be a lack of pigmentation. Providing adequate light is crucial for maintaining the vibrant green color of a healthy jade plant.
C. Temperature fluctuations
Temperature fluctuations can also influence the color of your jade plant. Cold temperatures, especially below their preferred range of 65-75°F (18-24°C), can cause the leaves to turn a darker shade. Conversely, exposure to high temperatures, above 85°F (29°C), can lead to a color change as well. It is important to ensure that your jade plant is kept in a stable temperature environment to prevent any unwanted color variations.
D. Overwatering or underwatering
Overwatering or underwatering your jade plant can also affect its color. Both of these watering extremes can stress the plant, leading to changes in its pigmentation. Overwatering can cause the roots to become waterlogged, leading to root rot and inadequate nutrient uptake. This can result in pale or yellowing leaves. On the other hand, underwatering deprives the plant of essential moisture, causing the leaves to droop and lose their vibrancy.
E. Nutrient deficiency
A nutrient deficiency can cause your jade plant to change color. Lack of nitrogen, phosphorus, iron, or magnesium can all impact the plant’s ability to produce chlorophyll, which gives it its green color. Nitrogen deficiency, for example, can cause the leaves to turn yellow, while phosphorus deficiency may result in a purple tint. It is important to provide your jade plant with a balanced fertilizer to ensure it receives all the necessary nutrients.
F. Pest infestation
Pests can also be a factor in the color change of your jade plant. Common pests that can infest jade plants include spider mites, mealybugs, scale insects, and aphids.

When the soil becomes waterlogged, the roots may suffer from root rot, impeding the plant’s ability to absorb essential nutrients properly. This can result in pale or yellowing leaves. It is important to water your jade plant appropriately by allowing the soil to dry out slightly between waterings to avoid overwatering and associated color changes.
B. Underwatering and color change
Similarly, underwatering your jade plant can also cause changes in its color. When the plant does not receive enough water, it can become stressed and show signs of dehydration. The leaves may wilt, lose their vibrancy, and potentially turn yellow or brown. Ensuring consistent and adequate watering, allowing the soil to dry out slightly before watering again, is crucial in keeping your jade plant healthy and maintaining its color.
VI. Nutrient deficiency and color change
A. Lack of nitrogen
A deficiency in nitrogen can cause your jade plant’s leaves to turn yellow. Nitrogen is a vital nutrient for plants as it plays a crucial role in chlorophyll production. When the plant lacks nitrogen, it struggles to produce sufficient chlorophyll, resulting in yellowing leaves. Providing a balanced fertilizer specifically formulated for jade plants can help address nitrogen deficiencies and restore the plant’s green color.
B. Lack of phosphorus
Jade plants that lack phosphorus may develop a purple tint in their leaves. Phosphorus is essential for energy transfer and overall plant growth. Without an adequate supply of phosphorus, the plant cannot properly metabolize energy, leading to the development of anthocyanin, a purple pigment. Ensuring your jade plant receives a fertilizer with a balanced phosphorus ratio can help prevent phosphorus deficiency and maintain its green coloration.
C. Lack of iron
When a jade plant lacks iron, its leaves may turn yellow or develop a pale appearance. Iron is a key element for chlorophyll synthesis, and its deficiency can inhibit the plant’s ability to produce sufficient chlorophyll. This results in a lack of green coloration and a more yellowish tone. Applying a chelated iron fertilizer or incorporating iron-rich organic matter into the soil can help address iron deficiency and promote a healthier color in the leaves.
D. Lack of magnesium
Magnesium deficiency can also lead to a color change in your jade plant. When the plant lacks magnesium, the leaves may develop interveinal chlorosis, which is characterized by yellowing between the leaf veins. Magnesium is vital for chlorophyll synthesis and overall plant health. To correct magnesium deficiency, applying a magnesium-rich fertilizer specifically formulated for plants can help restore the green color of your jade plant.
VII. Common pests that can affect jade plant color
A. Spider mites
Spider mites are tiny pests that can infest jade plants and cause damage to the leaves. They feed on the plant’s sap, leading to yellowing or stippling of the leaves.
