You may be awaiting the blooming of your honeysuckle. Or if it has already blossomed, then the leaves would turn yellow. Leaves turning yellow may just be a case of fall approaching. However, the most important thing to notice is if the leaves are turning yellow in the middle of the spring, then there may be something wrong with the overall way you’re taking care of honeysuckle.

Honeysuckle is one of the most common plants that you would want in your garden. However, you would still have to take care of the plant to ensure you get the best out of it. Many things may go wrong with the plant when you are taking care of it. If you feel like the leaves on your honeysuckle are turning yellow and you can’t identify the cause, you may want to look at certain categories to figure out where you’re lacking.

You will find many species of honeysuckle, which could either be vines or shrubs. The level of care you could afford to a honeysuckle plant would depend on the species it belongs to. However, the kind of care you give is generally the same because you would have to check very similar things generally.

Why Are My Honeysuckle Leaves Turning Yellow?

There are many reasons for your honeysuckle leaves turning yellow. Honeysuckle is a plant. Thus, like any other plant, you must take care of certain parameters to ensure the leaves are not turning yellow.


Honeysuckle leaves can lose their chlorophyll and die off when there is soil that needs nutrients, so if you feel like your honeysuckle leaves are turning yellow suddenly, you may initially want to look for the soil composition. If you don’t need or try to add the right fertilizer to the soil, your plant will turn yellow.

You will have to figure out what is lacking in your roots. The way to do this is to gather some of the soil from your honeysuckle plant, and then you can transfer it to a plant and send it to the lab so that you can understand which nutrients are lacking from your overall soil structures. Once you figure out which nutrient is lacking, you can apply the fertilizer accordingly.

If you don’t have the time to do this, you could add a generic fertilizer so that the plant has enough fertilizer to follow through on. However, if you feel like some growth still needs to occur, you may have to go through the process all over again. Nitrogen is most often the reason that your leaves may be turning yellow.

Nitrogen deficiency occurs quite often in Honeysuckle plants. This kind of problem appears when you don’t know how to feed a plant properly. If your honeysuckle plant doesn’t have enough nitrogen in the soil, then chlorosis might occur. Chlorosis is when the plant leaves start mottling or losing color due to external conditions.

The way this happens would be that the leaves would first start losing their colour. Once they start losing their color, you will see they are turning yellow. You would again need to get to the nearest lab to test the soil so you can better understand what is less.

Some tips for you to prevent nutrient deficiency in the soil are as follows:

  1. Fertilize your plant regularly
  2. Add water to the plants so that uptake of nutrients is easier
  3. Add slow-acting fertilizers, so the nutrient uptake is over some time.

Many experts advise using a fertilizer that takes time to interact. It augments the soil without having to harm the plant. You could use a fertilizer for all kinds of purposes if that seems easier to you. The correct time and kind of fertilizer are necessary to have a plant that grows easily.


Another thing that could be wrong with your plant is that it could be some sort of disease. The diseases may be in the form of fungal or bacterial diseases. There are many different kinds of diseases that your plant could encounter. Some powdery mildew may manifest as a fungus on the lower side of your honeysuckle leaves.


Powdery mildew occurs due to fungal pathogens and can easily fall into the lower end of the honeysuckle. Wet leaves are generally a great breeding ground for powdery mildew. You kind of understand from the name that the leaves will get completely covered in the white and powdery layer.

You would also be able to see some white layer formation on buds, stems and branch tips. The leaves will turn yellow and fall off if you have powdery mildew.

Some ways to protect powdery mildew on honeysuckle:

  1. You shouldn’t get any moisture on the honeysuckle leaves when you’re watering the plant. You could also use drip watering so you don’t get water in places you don’t want it.
  2. You should also make sure that there’s the right kind of air circulation near the honeysuckle. You would also want to space the honey suckle a little ways apart from another.
  3. You also want to ensure that you don’t accidentally get your tools infected.
  4. You can also add a tablespoon of Baking Soda and mix it with half a teaspoon of detergent in one whole gallon of water, and you can spray the infected parts of the honeysuckle.

Leaf Blight

Your honeysuckle might also have a leaf blight disease that would convert green yellows into yellow. Yellowing of your leaf tissue is the first instance that your leaf has leaf blight disease. If the disease is allowed to progress, you may have darker-colored leaves that turn brown or black that you may have a severe problem with. To save your honeysuckle plant from the leaf blight, you would have to cut the infect parts of the plant right off.

You could also use spraying copper-based fungicides in an efficient way that could control the disease. You would also have to start spraying the new vines as soon as they emerged so you could protect the new buds.

You would also have to spray the new vine blossoms so you could prevent an infection. You can also spray the healthy leaves with Neem Oil, a non-toxic organic fungicide. You would also want to look at all the healthier leaves and then apply neem oil to it all.


Another disease that could be a problem for your honeysuckle. Canker is also often present in honeysuckle. The yellowing or discoloration of leaves can be seen on the honeysuckle when the Canker disease infects it. Cankers can exist because of several fungal pathogens. The leaves could also wilt and then drop off.

You can also take note of the black spots on the lower sides of the black spots and the underside of the leaves. These could sometimes be the breeding ground for all kinds of pathogens that arrive from fungi.  

If you notice one of the symptoms and don’t notice them immediately, the disease can spread to further parts of the plant. You could also try to cut off or remove the infected leaves/stems from the honeysuckle immediately after you notice them. If you don’t see it the way you want, you could also have the disease spread to further parts. You would have to follow the same steps for this disease that you would have for the leaf blight disease.

Black Aphids

Honeysuckle leaves can also become yellow and mottled when a severe insect infestation occurs. These insects are generally aphids that are tiny that grow and reproduce rapidly.

Ants generally carry aphids to the honeysuckle. They have a symbiotic relationship when exchanging the sweet honeydew that the aphids produce.

The honeydew that the aphids produce can cause more opportunities for fungal inhabitation. The black fungus outgrowth can also be called Sooty Mold at times.

The way to take care of these aphids can be in the following ways:

  1. You can apply yellow notes all around the honeysuckle to figure out the aphid infestation during the initial stages.
  2. You can manually remove the aphids by dislodging them. You can also use other methods, such as a garden hose that can release water at high pressure.
  3. You can also use other mechanical ways to remove an affected branch’s aphids. The way to do this properly would be to remove a cotton bud or a cotton ball that you have already dipped in alcohol.
  4. You can then go ahead and spray more neem oil on the parts to rid yourself of the annoying aphids.
  5. If you feel like the aphids are too much or severe, you will have to attack with insecticidal soap to make it feel better and for the infestation to die down.

Moisture Imbalance or Improper Watering

If it feels like your honeysuckle leaves are turning yellow, then you may want to monitor the kind and amount of water you provide. Honeysuckle has to be watered in a specific balance to grow in the best conditions. If you add too much water to any plant, there will be problems. The same is the case with honeysuckle. Excessive watering could lead to drainage or a lack of nutrient uptake, which could mean you have many more yellow leaves.

You must water them consistently when the honeysuckle plants are growing and budding. You would need to add about an inch of water every week so the water doesn’t lack. Once you had enough growth of about a year. You can maintain moisture in the soil from there on. You would also need access to soil that is well-draining so that you can have the best kind of development regarding the growth and leaves in the long run.

If you want the right amount of water going into the plants, you can buy a proper water meter. This means that you could keep checking the moisture level, which would allow you to no when your soil is drying out and when it doesn’t need any more water.

Weather Issues

You may not think climate and environmental factors can cause much trouble regarding honeysuckle leaves. However, they bring about a fair bit. The honeysuckle plant can be extremely popular in places such as temperate regions. If you feel like you live in a place with constant climate change, then you may want to take the necessary precautions.

You also want to be careful of the soil’s pH levels, as this could create many issues for you.

You should generally not go for plants that don’t perform well in your kind of weather. Environmental stress is one of the common issues where the leaves turn yellow with relative ease. You should thus be aware of the kind of sunlight exposure and humidity you have within the soil. It affects the pH of the soil as well, which is why you have to be careful with how you proceed.

Final Thoughts

If you have a honeysuckle plant which has yellowing leaves, then you may be in trouble, as yellow leaves can change the complete appearance of a honeysuckle plant. You would want to look out for the possible causes so that you can apply the fixes without harming the plant or the leaves in any major way.
