Red Star Jasmine Leaves: Causes & Solutions

Jasmines are truly beautiful plants. They are commonly known to have gorgeous white or yellow flowers. Not to mention they have the best-smelling natural fragrances of all time.

It is a great plant to have either in the garden or indoors. Besides its beauty, it has many different beneficial uses. Taking care of the jasmine plant is easy to a certain extent. It does not require much attention and care. However, Any jasmine owner needs to know what damages the jasmine plant.

Have you ever noticed your jasmine plant’s leaves turning an unusual shade of red and wondered why? As a lifelong experienced gardener, I can tell you that Jasmine leaves change of color can be caused by many different factors. The foliage can turn either red, yellow, pale yellow, purple, lighter green or brown. Each color tells us a different thing.

The Cause Why Jasmine Leaves Are Turning Red

The Scientific Explanation of the Leaves Turning Red

Generally, when leaves turn red, a chemical called anthocyanins is produced. This phenomenon occurs from the sugar-built-in plants reacting with proteins in the cell sap. This natural reaction creates the pigment that turns green leaves into red leaves. In some cases, the pigment from chlorophyll reflects different shades of red and purple.

More details on the Causes and Solutions for Red Leaves in Jasmine Plants

1. Natural Causes

In most cases, red leaves are normal. They can indicate the beginning of a new season. That only if there was still a noticeable growth of new leaves and the old red leaves should fall after a while. If otherwise, your plant needs help.

Change of the season is the number one reason why leaves turn red. Generally, the change of seasons is not something to worry about because it is all natural and it happens very often. After a while, the color will go back to green. Give your red leaves some time before judging the issue. If your plant remains red and there is no growth, that’s when you need to worry.

2. Water

Jasmine does not require a lot of water. However, it does not like dry soil as well. It needs rich soil with a good draining system. Water stress can create many problems and among them is red leaves. Water stress will disturb the phosphorus and the sugar which will lead to creating red pigmentation.


Water stress is a very common cause. Too much water can kill any plant out there. In the case of jasmine plants, the leaves might turn red and eventually die. To check if you’re overwatering your plant, you can notice that the top of the soil turns greenish (due to algae) and the soil will also look too compressed.

As a solution, you can turn the soil over using a shovel. You can also try to provide a drainage system so that the access water can be ditched.

Underwatering problems can be simply solved by watering your plant three times a week during spring and fall. Once a week during winter and every two days during summer. However, if your region is too hot during summer, water your plant every day.

3. Nutrient Deficiency

Nutrient deficiency is often responsible for the color change of any plant’s foliage. Premature senescence in the early season is related to a lack of nutrients. Thus, it will turn your jasmine leaves red.

An absence of one of the following minerals could be the reason why the leaves are turning red: nitrogen (N), phosphorus (P), magnesium (Mg), or potassium (K).

You can tell when your plant lacks phosphorus when the lower short leaves turn red. This happens because the sugar built up in the cell sap increases and causes red pigmentation. The redness can appear either covering the whole leaf or as spots.

4. Plant Stress

The cause of red leaves in jasmine can be because it is under stress. That means your plant is lacking feed, overwatered, underwatered, or its environment is too cold.

Lack of Nutrients

Make sure you provide the necessary minerals. Jasmine plants love to grow in rich soil, you can feed it seaweed and other solutions provided in the nursery. Rich soil makes all plants happy and healthy.

Cold Weather

If you live in an area where the winter is too cold, transfer your plant into a pot and put it indoors. Frost can directly kill your plant within a couple of days. So you need to be careful during winter and watch over your plants.

5. Pruning

Jasmine leaves typically do not turn red solely due to pruning done incorrectly. The color change in jasmine leaves is primarily influenced by factors like seasonal changes, temperature fluctuations, and the plant’s natural growth cycle.

Pruning, when done improperly, can stress the plant and potentially lead to leaf discoloration or damage, but it is not the primary cause of leaves turning red.

Improper pruning can affect the overall health of the jasmine plant, making it more susceptible to stress factors and potentially compromising its ability to adapt to changing environmental conditions.

To maintain the health and appearance of your jasmine plant, it’s essential to follow proper pruning techniques and consider other factors such as sunlight, temperature, and soil conditions that may contribute to leaf color changes.

6. Pests and Diseases

Pests and diseases can indeed cause jasmine leaves to turn red. When jasmine plants are infested with pests or affected by diseases, it can lead to various symptoms, including discoloration of the leaves. Here are a few common examples:

  1. Spider Mites: Spider mites are tiny pests that suck the sap from plant leaves. Their feeding can cause stippling or speckling on the leaves, which may eventually turn the affected areas reddish or brownish.
  2. Fungal Infections: Fungal diseases like rust or powdery mildew can affect jasmine leaves. These infections often manifest as white or rusty-colored patches on the leaves, which can sometimes turn reddish as the disease progresses.
  3. Bacterial Infections: Bacterial diseases can also lead to leaf discoloration. These infections may cause spots or lesions on the leaves, which can sometimes appear reddish or brownish.

To prevent and address these issues, it’s essential to maintain proper care for your jasmine plant, including regular inspection for pests and diseases, providing appropriate watering, and ensuring proper nutrition. Early detection and appropriate treatment are key to keeping your jasmine leaves healthy and their color vibrant.

7. Sun Exposure

sun exposure can indeed cause jasmine leaves to turn red. While jasmine plants generally thrive in full sun to partial shade, excessive sun exposure, especially during hot and dry periods, can stress the plant and lead to various issues, including leaf discoloration.

Here’s how sun exposure can cause jasmine leaves to turn red:

  1. Sunburn: Just like us, humans, plants can also get sunburned. Prolonged exposure to intense sunlight, especially in the absence of adequate moisture, can cause the leaves to develop red or brown patches. These areas of the leaf are essentially “burned” by the sun’s UV rays.
  2. Heat Stress: Excessive heat, particularly in combination with high temperatures, can stress the jasmine plant. This stress can lead to changes in leaf color, and the leaves may turn red or yellow as a response to the environmental stress.
  3. Drought Stress: If the jasmine plant doesn’t receive enough water during periods of intense sun exposure, it can become drought-stressed. Drought stress can result in leaf wilting and discoloration, often appearing as red or brown edges or tips on the leaves.

To prevent sun-induced leaf discoloration, it’s important to ensure that your jasmine plant receives the appropriate amount of sunlight for its specific variety and is adequately watered, especially during hot and dry weather. Providing some shade during the hottest part of the day or heatwaves can also help protect the plant from excessive sun exposure. Proper care and attention to its environmental needs will help keep your jasmine leaves healthy and their color vibrant.

8. Plant Age and Life Cycle

Understanding Natural Aging: As jasmine leaves age, they may turn red before falling off. This is a normal part of the plant’s lifecycle and typically doesn’t require intervention unless it’s widespread across the plant.


To feed your plant with any minerals, you need to get your soil tested first. Some nutrients such as phosphorus can be dangerous if added while it is already in the soil. Too much phosphorus can kill a plant and damage the environment.
