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.
Reduce your watering frequency when you fear your plants are being overwatered, and follow these steps to determine whether they may be lacking in nutrients:
Here are some indicators of yellowing on the Centranthus ruber brought on by its numerous flaws:
- Magnesium deficiency starts as yellow patches between leaf veins on older leaves. Veins stay green as yellow moves from the leaf center out. Leaf edges turn yellow last.
- Iron deficiency also shows as yellowing between leaf veins, but it hits young leaves on plant tops and branch tips first.
- Sulfur shortage first affects the youngest leaves, turning them entirely yellow.
- 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

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 Spur valerian sunburned?
It is simple to determine whether your Spur valerian (your Centranthus ruber) has sunburn. Your plant will change color in this instance, beginning to turn yellow or white, much like it does on us.
The leaves of your Spur valerian can also change color in case it gets too much water or not enough light, as we saw above.
To find out if the yellow leaves have been sunburned, look at the part of the bottom that is tinted closer to the base. The yellow leaf is probably burnt and not something else if this portion stays greener.

Should I leave my Centranthus ruber in direct sunlight?
No! Don’t leave your Centranthus ruber (or Spur valerian) in the sun if it displays the symptoms mentioned above; that’s why it’s in such a bad situation.
Our Solution
As stated in the paragraph above, the cure is straightforward: simply position your plant’s Spur valerian 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 Centranthus ruber 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.
Whether your Centranthus ruber 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.
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 Spur valerian right away after a dry time because you think it needs a lot of water.
This is the case, but giving too much water at once is the best way to finish it off, you should actually water the soil normally, resuming a quiet watering rhythm.
Caring Tips for Centranthus ruber
Water Occasionally
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 Centranthus ruber.
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
It’s also a good idea to keep your Centranthus ruber at a constant temperature, especially if it’s kept indoors. In general, at GreenShack, we suggest booking a temperature between 65 and 85 degrees F. Of course, keep your Centranthus ruber away from radiators, air conditioners, and other sources of hot or cold air.
Keep your Spur valerian 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.
This would also make the pests happy, a real descent into hell for your Spur valerian.
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 should be mindful of your drainage, and if they don’t already have them, we suggest selecting a saucer and a pot with drainage holes.
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!)
