Japanese honeysuckle: Diseases and Remedies (2-minute Read)

NOTE: The terms Japanese honeysuckle and Lonicera japonica are identical in this text; in reality, Lonicera japonica is Japanese honeysuckle’s biological word.

Japanese honeysuckle (Lonicera japonica) is an evergreen vine that is usually evergreen in warmer areas. It has a long bloom period and fragrant flowers that bloom all summer and into fall. It is considered an Invasive species because it has escaped cultivation and crowds out native species.

WARNING: Keep in mind that Lonicera japonica (also Japanese honeysuckle) is toxic to Humans and Pets.

Why does my Japanese honeysuckle have gray mold spots?

Gray mold spots are a type of fungus that is found a lot in flowers, and spreads quite rapidly. If you notice brown (or gray) spots, it is probably this fungus. Don’t ignore these symptoms, as they may end up killing your plant.

Our Solution

The answer is obvious once you recognize the cause of the problem. Most frequently, it results from the Lonicera japonica being overwatered. We strongly advise you to remove the damaged plant parts, cut off the diseased roots and leaves, and then repot your plant in a new container with sterile potting soil.

Why does my Japanese honeysuckle have leaf spots?

Leaf We provide you with all the information you need to identify and save your plants if they display signs like leaves that suddenly change color or wilt/droop. This sort of sickness is one of the most aggravating for Japanese honeysuckle owners.

Why are my Japanese honeysuckle leaves turning yellow?

Yellowing leaves are arguably the most prevalent issue in the gardening world. Overwatering or a lack of nutrients are the 2 main causes of this issue.

When it’s overwatering, simply reduce your watering frequency, and if you think it’s a nutrient deficiency, here’s how to check it:

Each deficiency produces a different yellowing on the Lonicera japonica in question, here’s how to spot them:

  • Yellow patches between leaf veins on elder leaves are the first sign of magnesium shortage. Veins continue to be green while the leaf’s core turns yellow. The leaf’s edges yellow last.
  • Iron deficiency also shows as yellowing between leaf veins, but it hits young leaves on plant tops and branch tips first.
  • Sulfur deficiency starts with the newest leaves, turning them yellow throughout.
  • Insufficient potassium causes the leaf edges to turn brilliant yellow while the interior of the leaf stays green. Older leaves show the symptoms initially, and the leaf edges quickly darken.
  • A lack of nitrogen is indicated by a widespread yellowing. Older, inner leaves are the first to yellow. As the yellowing progresses, it eventually touches young leaves as well.

Our Solution

According to the symptoms mentioned above, you just have to act accordingly. You can reduce your watering frequency, or fix a deficiency in Potassium, or Nitrogen, for that, you just have to buy a special soil for your deficiency, a consultant in a gardening store will know perfectly well how to inform you.

Is my Japanese honeysuckle sunburned?

You can easily tell if your Japanese honeysuckle (your Lonicera japonica) has a sunburn. In this case, your plant will change color, starting to turn yellow or white, much like it does on us.

Sunburned

The leaves of your Japanese honeysuckle can also change color in case it gets too much water or not enough light, as we saw above.

The bottom of the yellow leaves with a shaded area closer to the base can be examined to determine if they have been sunburned. If this part remains greener, the yellow leaf is most likely sunburned and not something else.

Why are my Japanese honeysuckle leaves turning brown?

The classic sign that a plant has been overexposed to direct sunlight and sunburned is the development of browning leaves. Rest assured that while this may probably save your plant from dying, it will adversely affect its growth.

Should I leave my Lonicera japonica in direct sunlight?

No! Don’t leave your Lonicera japonica (or Japanese honeysuckle) in the sun if it displays the symptoms mentioned above; that’s why it’s in such a bad situation.

Our Solution

The remedy, as said in the paragraph above, is simple: just move your plant’s Japanese honeysuckle out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.

Why are my Lonicera japonica leaves drooping or wilting ?

When you become dehydrated, this usually happens. Large plants are more vulnerable since they need more water on a regular basis than smaller plants.

Drooping

An easy way to know if your Lonicera japonica is lacking water is to under-weigh its pot, if it looks light, it means that the soil and the roots are probably quite dry, and therefore need water!

Our Solution

If the soil in the container is completely dry, you must first moisten it to guarantee that your plant’s roots absorb the benefits of the water. One common mistake is to drown the Japanese honeysuckle right away after a dry time because you think it needs a lot of water.

This is true, but the easiest way to end it is to give too much water at once. Instead, you should water the soil properly, returning to a peaceful watering rhythm.

Caring Tips for Lonicera japonica

Water Occasionally

Water is necessary for your plant to live, but timing and amount of watering must be balanced. Overwatering could have disastrous effects on your own name, as we already mentioned.

The best way to know if your plant needs water or not is to touch the soil, if you feel it is still wet, it is probably a good idea to wait a few more days.

Always keep temperatures stable

It is also a good idea to keep your Lonicera japonica at a stable temperature (especially if it is kept indoors!). At GreenShack, we generally recommend staying in the 65 and 85 degrees F range. Of course, do not place your Lonicera japonica near a source of hot (or cold) air such as A/C units, radiators or the like.

Keep your Japanese honeysuckle Dust-Free

This one concerns indoor plants, just like on your furniture, dust is also deposited on the leaves of your indoor plants, the problem is that it can prevent them from receiving the necessary light, this would slow down (or even stop) the photosynthesis process, and eventually, they would lose their colors.

For your Japanese honeysuckle, this would be a true descent into hell, and it would also appease the pests.

To remove the dust from the leaves of your plant, take a microfiber cloth and gently rub the leaves. You can wet the cloth to make it easier to remove the dust, but never use corrosive products (such as rubbing alcohol!)

Keep drainage in mind

If you have a tendency to overwater, you need to keep an eye on your drainage, we advise you to opt for a pot with drainage holes if it is not already the case and a saucer.

You can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the interim if your pots don’t already have holes in them. This will help to form a channel so that the water doesn’t pool there for too long (preventing the rot of the roots!).
