If you’re like most gardeners, you probably love the sight of Plumeria flowers in bloom.
But when your plumeria leaves turn yellow, it’s not such a pretty sight.
This is a common problem for Plumeria growers.
The good news is that there are many solutions, and most of them are easy to implement.
Here we will explore the 13 most common causes of yellowing Plumeria leaves and what you can do to fix the problem.
What Causes Plumeria Leaves to Turn Yellow? (And How To Fix It)
Plumeria plants are native to tropical regions and are commonly used as ornamental plants in indoor and outdoor gardens.
They are known for their beautiful, fragrant flowers, which come in various colors.
However, Plumeria plants can sometimes experience yellowing leaves.
This is a common problem that Plumeria growers face, but the good news is that there are many solutions.
Let’s look at the 13 most common causes of yellow Plumeria leaves and what you can do to fix the problem.
1. Too Much Water
Plumeria leaves turning yellow can be due to too much water.
Overwatering can cause the leaves to suffocate and turn yellow.
If you see Plumeria leaves turning yellow, check the roots to see if they are waterlogged.
If the roots are soggy, it’s a sign that the plant is getting too much water.
Plumeria plants need well-drained soil that is only slightly moist.
The best way to determine if your Plumeria needs water is to feel the soil around the plant.
If the soil is dry, then it is time to water Plumeria.
Overwatering Plumeria is a common problem, so check the soil before watering.
How To Fix It
If you see that the leaves are already turning yellow, stop watering Plumeria and let the soil dry out.
Plumerias are drought tolerant and can survive for long periods without water, so do not be afraid to let the soil dry out completely.
Once the soil is dry, you can resume watering Plumeria, but be sure to water only when the soil is dry.
Withholding water will help Plumeria recover from overwatering and should prevent the leaves from turning yellow.
2. Not Enough Water
Plumeria leaves may turn yellow due to a lack of water.
Plumerias are native to tropical and subtropical regions and need regular watering, especially when the weather is hot and dry.
When the leaves don’t have enough water, they can’t function properly and turn yellow.
Plumeria should be watered deeply, about once a week, to ensure the roots get enough moisture.
How To Fix It
If Plumeria leaves turn yellow due to a lack of water, start watering the plant more frequently.
Water Plumeria deeply, about once a week, and make sure the soil around the plant is moist but not soggy.
If you live in a hot or dry climate, you may need to water Plumeria more often.
3. Nutrient Deficiency
Plumeria leaves may turn yellow due to a nutrient deficiency.
The most common nutrient deficiencies that cause yellowing leaves are a lack of nitrogen, phosphorus, or potassium.
Plumeria plants need these nutrients to stay healthy and produce new growth.
A lack of any one of these nutrients can cause the leaves to turn yellow and eventually drop off the plant.
Nutrient deficiency can be caused by poor soil quality, inadequate fertilization, or leaching from too much watering.
How To Fix It
If Plumeria leaves turn yellow due to a nutrient deficiency, the best solution is to fertilize the plant.
Use a balanced fertilizer that contains nitrogen, phosphorus, and potassium.
Fertilize Plumeria every two weeks during the growing season.
You can also amend the soil with compost or manure to improve the soil’s quality and help Plumeria get the nutrients it needs.
4. Pest Infestation
The most common pests are scale insects and mealybugs.
These pests suck the sap from the leaves, causing them to turn yellow and eventually drop off.
Plumeria plants are also susceptible to spider mites, which can cause the leaves to turn yellow and become covered with webbing.
Pests can also transmit diseases that can cause Plumeria leaves to turn yellow.
How To Fix It
If Plumeria leaves turn yellow due to pests, the best solution is to treat the plant with neem oil.
Neem oil is a natural pesticide that will kill pests and prevent them from returning.
You can also use insecticidal soap or horticultural oil to control pests.
This treatment should be repeated every week until the pests are gone.
5. Lack of Light
Plumeria leaves typically turn yellow due to a lack of light.
Plumeria is native to tropical regions and requires a minimum of six hours of bright light per day to thrive.
When Plumeria are grown in lower light conditions, the leaves produce less chlorophyll, which gives the leaves their green color.
As a result, the leaves may turn yellow or even brown.
How To Fix It
If Plumeria leaves turn yellow due to a lack of light, the best solution is to move the plant to a brighter location.
Plumeria should be grown in an area that receives at least six hours of bright light per day.
If possible, move Plumeria outdoors during the summer months to ensure it gets enough light.
When indoors, Plumeria can be placed near a south- or west-facing window or under grow lights.
6. Too Much Heat
Plumeria leaves usually turn yellow when they experience too much heat.
The leaves of the Plumeria are very thin and delicate, and they can’t handle high temperatures for very long.
When the leaves are exposed to excessive heat, they will start to turn yellow and eventually dry up and fall off.
Plumeria plants are native to tropical regions, so they’re used to warm weather.
However, if the temperature gets too hot, even for a Plumeria, the leaves will turn yellow as a way of protecting the plant from further damage.
How To Fix It
If Plumeria leaves turn yellow due to too much heat, the best solution is to move the plant to a cooler location.
Plumeria should be grown in an area with temperatures between 60-80 degrees Fahrenheit.
If the temperature gets too hot, Plumeria can be moved outdoors or to a cooler room in the house.
Plumeria should never be placed in direct sunlight, as this will cause the leaves to turn yellow and eventually burn.
7. Frost Damage
Plumeria leaves are known to turn yellow when they suffer frost damage.
Plumeria is a flowering plant that is native to tropical and subtropical regions.
The leaves of the Plumeria plant are sensitive to cold temperatures and can be easily damaged by frost.
When the leaves of the Plumeria plant are exposed to frost, they will turn yellow and eventually die.
How To Fix It
If Plumeria leaves turn yellow due to frost damage, the best solution is to move the plant to a warmer location.
Plumeria should be grown in an area that has temperatures above freezing.
If Plumeria is exposed to frost, the leaves will turn yellow and eventually die.
The best way to prevent this is to move Plumeria to a warmer location, such as indoors or to a greenhouse.
If you live in an area where Plumeria plants are exposed to frost, it is essential to protect the leaves of the Plumeria plant from frost damage.
There are a few ways to do this, such as covering the Plumeria plant with a tarp or blanket during periods of expected frost.
8. Overfertilization
Plumeria leaves are turning yellow because of overfertilization.
Fertilizers are important for Plumeria plants because they provide nutrients that Plumeria plants need to grow.
However, too much fertilizer can be harmful to Plumeria plants.
When Plumeria plants are overfertilized, the leaves turn yellow and eventually brown and fall off the plant.
Overfertilization can also cause Plumeria plants to stop blooming.
How To Fix It
If Plumeria leaves are turning yellow due to overfertilization, the best solution is to flush the soil with water to remove the excess fertilizer from the roots.
Plumeria plants should be fertilized every two weeks during the growing season.
They need only a small amount of fertilizer, so be sure to use fertilizer sparingly.
Your Plumeria plant will thank you for it!
9. Poor Soil Quality
Poor soil quality is another reason Plumeria leaves turn yellow.
Plumeria plants need well-drained, sandy soil to grow in.
If Plumeria is planted in a potting soil that is too dense or has poor drainage, the roots of the Plumeria plant will not be able to get the oxygen and water they need.
This will cause the leaves of Plumeria to turn yellow and eventually die.
How To Fix It
If Plumeria leaves turn yellow due to poor soil quality, the best solution is to repot Plumeria in well-drained, sandy soil.
Plumeria plants should be repotted every two years or so to ensure that they are getting the nutrients they need.
10. Transplant Shock
Transplant shock is another reason Plumeria leaves may turn yellow.
Plumeria plants are native to tropical and subtropical regions and do not like to be moved around.
When Plumeria plants are transplanted, the roots of the Plumeria plant are disturbed and can become damaged.
This will cause the plant to go into shock, which will cause the Plumeria leaves to curl, turn yellow and eventually die.
How To Fix It
If Plumeria leaves turn yellow due to transplant shock, the best solution is to give the Plumeria plant time to adjust to its new location.
Plumeria plants should be transplanted in the spring or summer when the weather is warm.
Plumeria plants will need time to adjust to their new location and should not be fertilized for the first few months.
After a few months, Plumeria plants should start to recover, and the plant leaves will turn green again.
11. Root Rot
Root rot is another reason Plumeria leaves may turn yellow.
Root rot is caused by too much water and not enough drainage.
When Plumeria roots are constantly wet, they will start to rot.
This will cause the Plumeria plant to become sick, and the leaves will turn yellow and eventually die.
If your Plumeria’s leaves are turning yellow, check the roots.
If they’re mushy or black, that’s a sure sign of root rot.
Root rot can be difficult to detect because it usually starts small and only affects a few roots.
However, root rot can spread quickly and kill your Plumeria plant if left unchecked.
How To Fix It
If Plumeria leaves turn yellow due to root rot, the best solution is to remove the affected roots and repot Plumeria in well-drained, sandy soil.
Plumeria plants should be repotted every two years or so to ensure that they are getting the nutrients they need.
12. Plumeria Rust
Plumeria rust is a fungal disease that can cause Plumeria leaves to turn yellow.
Plumeria rust is caused by a fungus that attacks Plumeria plants.
Plumeria rust usually starts as tiny, orange spots on the leaves of Plumeria plants.
If left unchecked, Plumeria rust can spread quickly and affect the entire plant. Plumeria rust can eventually kill Plumeria plants.
How To Fix It
If Plumeria leaves turn yellow due to Plumeria rust, the best solution is to remove the affected leaves and destroy them.
Plumeria plants should be treated with a fungicide to prevent Plumeria rust from spreading.
Plumeria plants infected with Plumeria rust should be isolated from other Plumeria plants to prevent the disease from spreading.
13. Natural Leaf Yellowing
Sometimes Plumeria leaves turn yellow and fall off as part of their natural life cycle.
Plumeria plants are deciduous plants, which means that they lose their leaves in the winter and grow new ones in the spring.
Plumeria leaves will turn yellow and fall off in the winter when the weather starts to get cold.
This is normal, and Plumeria plants will grow new leaves in the spring when the weather gets warm again.
If Plumeria leaves are turning yellow and falling off due to the plant’s natural life cycle, there is no need to worry. Plumeria plants will grow new leaves in the spring.
Why Are My Plumeria Leaves Turning Yellow in Winter?
Plumeria leaves are beautiful when they’re healthy and green.
But if your Plumeria leaves are turning yellow, it can be a sign that something is wrong.
