Trumpet vine: Diseases and Remedies (3-minute Read)

NOTE: Trumpet vine may be referred to as Campsis radicans in this article, in fact, those are the same plants, Campsis radicans is the botanical name for Trumpet vine.

Trumpet vine is a native North American plant with glossy dark green elliptical leaves that grow up to 15 inches long with seven to 11 serrated leaflets. During the summer months, clusters of trumpet-shaped red, orange, or yellow flowers appear around 1 to 3 inches long before giving way to bean-like seed capsule. The flowers are attractive to hummingbirds.

The leaves turn yellow in the fall before they fall off in the winter. Trumpet vine can grow up to 40 feet when it’s mature and should be grown with caution. New shoots can pop up yards away from the mother plant, quickly escaping the garden site, and forming thickets that can choke out other plants.

Why does my Trumpet vine 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

When you understand the root of the issue, the solution makes perfect sense. The majority of the time, it is caused by the Campsis radicans being overwatered. We urge you to cut off the infected roots and leaves, remove the affected sections of the plant, and then repot your plant in a fresh container with sterile potting soil.

Why does my Trumpet vine 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 Trumpet vine owners.

Why are my Trumpet vine 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.

Whether you think your plants are getting too much water, cut back on how often you water them, and take the following measures to see if they might be nutritionally deficient:

Each deficiency produces a different yellowing on the Campsis radicans 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.
  • Another indicator of iron deficiency is yellowing between leaf veins, but young leaves on plant tops and branch tips are first affected.
  • 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 broad yellowing indicates a nitrogen deficiency. Yellowing starts with older, inner leaves. Yellowing spreads as it advances, eventually touching new 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 Trumpet vine sunburned?

It is simple to determine whether your Trumpet vine (your Campsis radicans) has sunburn. Your plant will change color in this instance, beginning to turn yellow or white, much like it does on us.

Sunburned

The leaves of your Trumpet vine 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 Trumpet vine 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 Campsis radicans in direct sunlight?

No! If your Campsis radicans (or Trumpet vine) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Trumpet vine is in such a state!

Our Solution

As stated in the paragraph above, the cure is straightforward: simply position your plant’s Trumpet vine so that it is out of direct sunlight. With proper watering and this method, your plant should quickly come back to life.

Why are my Campsis radicans leaves drooping or wilting ?

This typically occurs when your Campsis radicans gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.

Drooping

You may quickly determine if your Campsis radicans plant needs water by under-weighing its pot; if it seems light, the soil and roots are probably fairly dry and require 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 Trumpet vine 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 Campsis radicans

Water Occasionally

Your plant needs water to survive, but it’s crucial to balance the amount and timing of watering. As we previously mentioned, overwatering could be catastrophic for your Campsis radicans.

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

Maintaining a consistent temperature for your Campsis radicans is also a good idea, especially if it is kept indoors. At GreenShack, we typically advise reserving a temperature between 65 and 85 degrees F. Of course, avoid positioning your Campsis radicans close to air conditioners, radiators, or other sources of hot or cold air.

Keep your Trumpet vine Dust-Free

This one relates to indoor plants. Just like your furniture, dust collects on the leaves of your indoor plants. The issue is that this can block the photosynthesis process from starting, which would cause the plants to gradually lose their color.

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

To remove the dust, gently rub the plant’s leaves with a microfiber cloth. Dust can be removed more easily with a damp cloth, but stay away from corrosive substances like 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!).
