NOTE: In this article, Leadwort and Ceratostigma plumbaginoides may be used interchangeably; in fact, Ceratostigma plumbaginoides is the botanical name for Leadwort.
Leadwort is a low-growing, mat-forming perennial ground cover. It has small leaves that emerge with a burgundy hue, turn glossy green in the summer, and then turn a blazing reddish-brown in the fall. In the middle of the summer, clusters of five-petal, star-shaped, bright blue flowers, similar to phlox blossoms, emerge on stalks rising above the foliage. Up until the first frost, the blooms can persist.
Why does my Ceratostigma plumbaginoides roots have rot?
If left untreated, root rot on your Leadwort (Ceratostigma plumbaginoides) can be fatal. For this reason, if the symptoms appear, we highly advise that you adhere to our recommendations to keep your plant alive: Blackened and softened roots.
Why does my Leadwort 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.
The answer is obvious once you recognize the cause of the problem. Most frequently, it results from the Ceratostigma plumbaginoides 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 Leadwort have leaf spots?
This type of disease is one of the most frustrating for Leadwort owners, we give you all the leads to spot and save your plants that present symptoms such as leaves that suddenly change color, or wilt/droop.
Why are my Leadwort 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:
Here are some signs of yellowing caused by the many deficiencies on the Ceratostigma plumbaginoides in question:
- 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.
- The newest leaves are first affected by sulfur deficiency, rendering them completely yellow.
- Leaf edges turning bright yellow but inside leaf remaining green are signs of potassium insufficiency. The symptoms first appear on older leaves, and the leaf edges quickly become dark.
- 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.
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 Leadwort sunburned?
You can easily tell if your Leadwort (your Ceratostigma plumbaginoides) has a sunburn. In this case, your plant will change color, starting to turn yellow or white, much like it does on us.
As we saw above, if your Leadwort receives too much water or not enough light, the leaves may also change color.
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 Leadwort leaves turning brown?
A plant’s browning leaves are typically a symptom that it has been sunburned and has been exposed to excessive amounts of direct sunlight. Don’t worry; your plant probably won’t perish as a result, but its growth will be negatively impacted.
Should I leave my Ceratostigma plumbaginoides in direct sunlight?
No! If your Ceratostigma plumbaginoides (or Leadwort) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Leadwort is in such a state!
As stated in the paragraph above, the cure is straightforward: simply position your plant’s Leadwort 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 Ceratostigma plumbaginoides leaves drooping or wilting ?
This typically occurs when your Ceratostigma plumbaginoides gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.
Whether your Ceratostigma plumbaginoides plant’s pot appears light, the soil and roots are likely fairly dry and need water, so you can readily tell if it needs to be hydrated.
If the soil in your plant’s pot is completely dry, you will need to start by moistening it so that the roots will also benefit from the water. A common mistake is to drown the Leadwort right after a dry period thinking that 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 Ceratostigma plumbaginoides
Water is essential to the survival of your plant, however, it is important to balance the rate of watering. As we explained above, overwatering could have fatal consequences for your Ceratostigma plumbaginoides.
Touching the soil will let you know whether your plant needs water or not; if it still feels damp, it’s generally best to wait a few more days.
Always keep temperatures stable
Maintaining a consistent temperature for your Ceratostigma plumbaginoides 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 Ceratostigma plumbaginoides close to air conditioners, radiators, or other sources of hot or cold air.
Keep your Leadwort 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.
This would be a true journey into hell for your Leadwort and would also satisfy 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.
In the meantime, if you don’t have holes in your pots, you can add volcanic rocks (or any rocks with holes) at the bottom of your pot, this way it will create a channel so that the water doesn’t stay in your skin too much (to avoid that roots start to rot!)
