Why are my Jasmine Leaves Curling? (Here is the Answer)

Do you have beautiful Jasmine in your house, but do you see that more and more leaves are curling? When you notice that your Jasmine leaves are curling, it can be difficult to understand why this is happening.

Curling of the leaves is one of the most common symptoms of a plant’s struggle. It occurs when the jasmine does not get enough water, nutrients or it is attacked by pests, which causes it to go into a state of stress. The leaves curl because they are trying to conserve energy by protecting themselves from getting damaged. This means that they are trying to protect their cell structure against excessive heat or cold, while still being able to function normally.

Let’s see the causes and remedies required to solve the problem.

Jasmine leaves curl for the following reasons:
1.Lack of water
2. Nutrient deficiency
3. Temperature stress
5. Aphids

1.Lack of water

First, a lack of water can cause the leaves on a jasmine plant to curl and begin to fall from their stems. Jasmine that gets too little water will curl its leaves to allow less water to evaporate.

The plant tries to compensate for the lack of water by rolling up its leaves. When exposed to sunlight, less water evaporates. If the plant is still not watered after the leaves have rolled up, they will fall off.

Jasmine that gets too little water will curl its leaves to allow less water to evaporate. Stick a finger in the potting soil and feel: is the soil dry? Then it’s time for some extra water. Other signs of insufficient watering are leaves that droop badly or turn yellow

You should also try spraying your jasmine plants with a solution of diluted bleach (1 cup per gallon) every few weeks throughout the summer months when you notice your plants are wilting due to low humidity levels or hot weather conditions.

Jasmine is a rather large shrub, sometimes reaching a height of 3 m. The root system of the plant is also quite developed and requires a sufficient amount of moisture. 

If the summer is hot and without precipitation, you should water your jasmine more often. 

How to treat Lack of Water

The best way to treat curly jasmine leaves is to give them proper amounts of water every day, especially during times when there is not much rainfall or snowfall.

You need to water the culture regularly, and most importantly – plentifully. In the spring, watering is carried out 2 times a week. During the dry period, the amount can be increased up to 3 times.

Note: a plant can show the same symptoms when it has been given too much water. After all, his roots will rot and he can no longer absorb water. 

So don’t just get the watering can, but first check the potting soil (and, if necessary, the roots) and check how dry or wet it is. 

2. Nutrient deficiency

The second reasons why jasmine leaves are curling is give by the lack of nutrients or excess of fertilizer. With a lack of nutrients, the leaf plate first turns pale, then folds and the leaf dies. It is important to feed in a timely manner, including mineral complexes. 

If a jasmine has low levels of molybdenum, manganese, magnesium, potassium, sulfur, nitrogen, copper or boron in its leaves, they will curl up.

If the edges of a jasmine’s leaves curl upward and outward and it becomes mottled on all sides with fine spots, then it lacks zinc.

The balance must also be maintained in the supply of various nutrients to the soil.

Apply fertilizer in a timely manner, in accordance with the instructions, and choose fertilizers suitable for jasmine. Compliance with the recommended doses is very important.

Excess of fertilizer

Another reason why the jasmine shrub curls at the top is excess use of fertilization. If over-fertilized, the top of the plant and any other new shoots will curl inward and the growth may look stunted.

Too much nitrogen in your soil will cause stems to become weak and break, which can lead to leaf curls. This can also happen if you overfeed your jasmine shurb with nutrients during blooming season due to high temperatures or lack of rainwater for irrigation purposes.

Because leaves can curl up due to an overdose of potassium, zinc, nitrogen and other elements, it is important not to exceed the recommended dosage when fertilizing.

How to treat Fertilizer Excess

To correct this, one should water without nutrients for a few days until the growth returns to normal.

If we have put some liquid fertilizer we can water one more time to wash away the substances present in the soil. If, on the other hand, we have put some chicken pelleted manure, in addition to watering, we must manually eliminate the fertilizer.

3. Temperature stress

A common cause of upward curling is temperature stress/change. Especially young still fragile jasmine do not tolerate temperature fluctuations well. Jasmine shurb will often respond to such stress by curling their leaves.

Lack of air during extreme heat, too much dampness and cold, drafts, sudden changes in temperature: all these factors have a very bad effect on the health of jasmine shrub, causing the leaves to curl outwards. It is simply a way for plants to protect themselves.

For example, jasmine may have been moved away from warm, good conditions in the greenhouse, to wetter and cooler conditions in the open field.

Usually jasmine placed on windowsills often experiences thermal shock. The reason is that in winter, the glass is cold and in summer it is very hot due to exposure to the direct rays of the sun.

Jasmines in the garden are known to enjoy areas with warm climates, so it’s no coincidence these are the same areas where leaves of this plant tend to curl when there is too much humidity in the air.

Most often, the leaves can begin to spin from the heat, especially if the summer turns out to be dry and watering is not adjusted. Timely moisturizing the bush, you can prevent them from falling off. 

Not to the liking of garden jasmine and cold with drafts. If the place does not fit, it is worth transplanting the plant into a more comfortable one, protected from the wind. At the same time, give preference to the sunny side – problems are also possible in the shade, and not only with the leaves.

How to treat Temperature stress

It is especially important to monitor the temperature in the greenhouse. There must be a thermometer in the greenhouse to monitor the air temperature. 

Do regular ventilation, do not put the pots in places where direct sunlight falls, do not allow strong drafts. In the open ground, create a shadow for young plants, create a watering regime and water the plants if necessary.


Like all flowering plants, jasmine loves light, but prolonged exposure to the sun is dangerous. It can get sunburned, causing the leaves to dry out and curl. This is s due to the plant’s need to decrease sun exposure and water loss. 

Often with too much light, especially the older leaves of your plant will curl up, the young leaves will have brown edges and be smaller in size. 

Jasmine is photophilous, grows well and blooms profusely in sunny rooms; however, in summer it needs to be shaded from hot sunlight. Jasmine is undemanding to heat. It grows well at a temperature of 68-70°F (20-22°C) and a little lower.

It is recommended to choose a place under the sparse crowns of trees or near buildings so that the plant stays in the shade for a certain period of daylight hours.

However, this does not mean that you can plant jasmine in a darkened area, such conditions will negatively affect flowering, and the shrub will often get sick.

Do the curled leaves of your plant also look brown, feel ‘crispy’ and is your plant in direct sunlight? Then it is a good idea to place your plant a bit further from the window or in a shadier spot. After a few days, you will see improvements in your jasmine leaves. 

5. Aphids

In other cases the curling may be due to the presence of aphids . Pest insects, such as aphids, can distort jasmine leaves and cause them to curl both outwards and inwards. Aphids are soft-bodied insects that are normally found on the underside of leaves and growing tips of the plant. 

Aphids, rely on the sap in your plant’s leaves to survive. And the more juice they suck from the leaves, the more they curl up. 

Aphids suck all the water out of the plant through the leaves. In this way they ensure that the entire plant dries out. Aphids can also cause your plant to curl its leaves because it has dried out.  

So check carefully whether you see unusual spots or small animals anywhere on the leaves. You should be able to spot them with the naked eye. And if you come across them that you do something about it as soon as possible. 

How to eliminate Aphids from Jasmine leaves

Their attack causes foliar curling and redness, up to the death of dry leaves and any buds, flowers or fruits. It can be contrasted chemically, or with natural solutions ( such as those listed in this article ). In this case, the ideal solution is a Marseille soap preparation.

If you see any, spray them with insecticidal soap. Repeat until they’re gone. If there is a severe infestation, you can cut back those areas of the plant.

Mix 20 ml of kitchen oil (sunflower oil or olive oil), 1 teaspoon of natural liquid soap, shake well and top up with water until you have 2 liters. 

Continue to spray jasmine leaves with the remedy weekly until the aphids insects are gone. You may also want to move them to a different place. This makes it more resistant to insects.

Remember that ladybugs are welcome in the greenhouse, they eat aphids!

How to prevent Jasmine Leaves Curling

  1. The first thing you need to do is make sure that the plants are getting enough water and nutrients.
  2. You should also ensure that they get plenty of sunlight and fresh air.
  3. Keep humidity levels low by keeping doors and windows closed, not allowing rain to run off your roof, and turning on fans when needed to dry rooms after a rainfall.
  4. Do not let the soil dry out or become too hot or cold.
  5. Don’t over-fertilize; use only enough fertilizer to maintain good health and vigor in the plant’s root system (don’t fertilize after flowering).


We hope that this article will help you recover your jasmine and that their new leaves will be green and healthy. You now know the reasons that can cause your jasmine to roll up its leaves. If you’re not sure where to start, don’t panic!
