Why Are Jasmine Leaves Turning Yellow (5 Causes & How to Prevent)
Many of you ask us why are jasmine leaves turning yellow and in this article we will give the answer!
There are two general causes for which jasmine leaves can turn yellow: the first, an excess of water and the second, lack of nutrients. When the jasmine is in a pot or surface where the soil is always waterlogged, all the jasmine leaves can turn yellow, in the same way that if the plant lacks nutrients such as nitrogen, which is responsible for giving greenness to plant.

Causes of Jasmine Leaves Turning Yellow
1.Waterlogging
The most common cause why jasmine leaves turn yellow is due to overwatering (waterlogging) and to a cultivation substratum kept humid for a long time, or even soaked with water, in fact jasmine plants are very afraid of water stagnation, especially when they are grown in pots.
Jasmine need frequent watering, but if we overdo it with water, we will suffocate the roots, preventing them from absorbing nutrients and causing this effect on the jasmine leaves.
If you are watering your jasmine plant too often, space out the watering frequency. Normally, a potted jasmine will have enough water with a watering every three days in the warm months and a weekly watering in the cold months.
Always water without flooding the substrate and check before doing so that the top layer of the substrate is dry.
It may also happen that the soil or pot of the jasmine does not offer adequate drainage and, although the irrigation frequency is correct, the substrate retains too much moisture.
Poor drainage is an almost guaranteed source of jasmine diseases , so it is very important that you locate it in an area of the garden where water does not accumulate, or that you prepare a light and slightly sandy substrate for it, in a pot with drainage holes.
Coconut fiber is always a good option in these cases, as well as a bed of river gravel.
2. Lack of water
Watering jasmine plants less than necessary causes them to drop most of the strong leaves so that the water that nourishes them is saved. So, before the jasmine leaves completely fall off, they turn yellow.
If the leaves turn yellow to a wrinkled texture and the entire jasmine seems to droop and lose strength, it most likely needs more water.
When one of your plants has suffered a severe drought, do not overwater it. Instead, submerge the entire pot in water for a few minutes, then allow the excess soil to drain away.
For many plants including jasmine, too little water for a longer period of time is harmful, its leaf will then first turn yellow and then dry out. Feel a little deeper into the soil with your fingers to make sure the plant is really dry.
The following applies to most dry plants: water well and cut off (part of) the yellowed leaves, so that the plant looks fresh again and the energy goes to the healthy leaves.
| Jasmine Watering Frequency | Soil Moisture Level |
|---|---|
| Every 3-4 days | Keep soil evenly moist |
| Once a week | Allow top inch of soil to dry out |
| Every 10-14 days | Allow top half of soil to dry out |
| Every 2-3 weeks | Allow soil to dry between watering |
| Varied | Adjust based on plant’s response |
3. Nutrient deficiency
If the jasmine lacks the necessary nutrients in the soil, this determine the appearance of yellow leaves. Fertilize your jasmine regularly with a commercially available universal fertilizer at the dose indicated on the package.
You can make organic fertilizer at home, the idea is to have a space reserved for this, usually in boxes. To do this, you can put eggshells, fruit shells, vegetables, coffee grounds, teas and grains.
Place in a container and cover with sawdust, dry leaves, straw or any other type of dry material. The composting process of this organic matter lasts around 30 days.
| Nutrient | Jasmine Deficiency Symptoms | Common Causes |
|---|---|---|
| Nitrogen (N) | Pale yellow leaves, stunted growth | Inadequate fertilization, poor soil quality |
| Iron (Fe) | Yellowing between leaf veins, leaf chlorosis | High soil pH, insufficient iron uptake |
| Magnesium (Mg) | Yellowing between leaf veins, leaf curling | Low soil magnesium levels, acidic soil |
| Zinc (Zn) | Yellowing of leaf margins, reduced leaf size | Zinc-deficient soil, poor nutrient uptake |
| Manganese (Mn) | Interveinal chlorosis, leaf browning | High pH soils, poor manganese availability |
Another reason for yellowing of the jasmine leaves, related to a nutrient deficiency, is a sign of nitrogen deficiencies. Nitrogen deficiencies occur when soil leaches. Too much water lowers the level of nitrogen present in the soil. Nitrogen plays a vital role in the process of photosynthesis, as any plant clinic will tell you.
The fall in the rate of nitrogen can also be noticed with the stagnation of the period of growth. If the growth of the vegetation is slowed down and it is not a usual rest period for this variety of plants, it is advisable to end this rest period and start a new period of growth.
Some deficiencies cause older jasmine leaves to turn yellow first, and in others the traits start in new growth. This is because a plant can move certain nutrients from leaf to leaf as needed.
When the jasmine plant is low in some nutrients such as nitrogen, phosphorus, potassium, magnesium and nickel, it can transfer the element from its older leaves to help it grow at least for a while. That is, the old foliage turns yellow and the green shoots.
4. Pests
In rare cases, yellow leaves indicate a pest infestation of the jasmine. Check your jasmine regularly for a healthy appearance, so you can recognize a possible pest infestation at an early stage.
Spider Mites
The first reason that leaves may turn yellow is a spider mites infestation, which is a very small insect that is found on the underside of the jasmine leaves. Treat the jasmine plant with potash soap at least 3-4 times with an interval of 5-7 days.
Scale Insects
Scale insects can appear on the jasmines during the spring season or in any case when the climate is mild. They are nothing more than very small insects, whose size does not exceed 3 mm, which suck the lifeblood of the plant by positioning itself on the leaves.
The initial damage caused by these insects is the nuisance of the shoots and leaves which, after being drained of their sap, turn to yellow and fall to the ground.
Mealybugs
Mealybugs are small biting and sap-sucking insects that weaken the plant and cause the jasmine leaves to turn yellow. In the long term, sooty mold , a black fungus, invades the plant, making it sticky and risking killing it.
Mealybugs should first be simply scraped off or showered off. If that doesn’t help, it’s best to tackle the pests with beneficial insects such as lacewings or ladybirds.
5. Natural Aging
If your jasmine does not show any of the changes mentioned above, the yellowing of the leaves is probably a result of natural aging. Because they are living beings, many species have a certain life span and end up deteriorating over time.
Yellowing leaves look alarming and sometimes they are. If your jasmine gets yellow leaves in the fall before the winter break, which then fall off, this is not a cause for concern, it is quite normal. Because the jasmine is, it sheds its leaves before wintering.
Another reasons why jasmine has yellow leaves is because of chlorosis. Plants need more than a dozen mineral nutrients to survive, and they must all come from their roots. So a soil test is the best way to find out what’s missing.
Chlorosis occurs when there is little chlorophyll in the leaves of the plant, or it has degraded. And chlorophyll deficiency occurs when photosynthesis for some reason is deficient .
This means disease for the jasmine plant , because photosynthesis is nothing more, nothing less, than the way the plant transforms food into energy. So, if the plant is sick, not being able to feed well or getting energy, it will die if you don’t solve the problem.
As long as you can’t see other more sinister developments like wilting or the loss of young leaves, there’s nothing to worry about. This is a perfectly natural process known as senescence, in which the leaf stops growing or photosynthesizing because the plant no longer needs it.
It loses its green color, dies and then disappears, leaving the rest of the jasmine to grow normally. It’s worth picking up the yellowing leaves, so they don’t become a haven for fungal diseases like botrytis but otherwise, you don’t have to do anything.
How to prevent jasmine leaves from turning yellow
To prevent jasmine leaves from turning yellow, you must follow these simple rules:
- If there is a lack of nutrients , fertilize or plant the jasmine in fresh soil. Fertilizing with mineral mixtures can be alternated with organic matter in order to prevent the leaves to turn yellow.
- In pots it is advisable to water when the soil is dry , without excess but regularly.
- Avoid over fertilization. Basically, you should fertilize sparingly. With too much fertilizer, the roots can burn, the jasmine leaves turn yellow and fall off. Therefore, it is better to add a little less fertilizer to the irrigation water than prescribed.
- Apply fertilizers that contain micronutrients. If the foliage continues to yellow despite proper treatment and fertilizers, use a foliar spray fertilizer.
- Jasmine needs well-draining soil. Repot the jasmine after loosening the soil with a peat mixture.
- If it is very hot, you should spray the jasmine more frequently. If the jasmine is too dark, this is first shown by the yellowing of the leaves. Find a more suitable location .
