NOTE: The terms Autumn crocus and Colchicum autumnale are identical in this text; in reality, Colchicum autumnale is Autumn crocus’s biological word.
The fall flowers need to be more than just the standard asters and mums. In early fall, the autumn crocus (Colchicum autumnale) makes its debut, though its foliage is just a memory by then.
The dark green leaves that are 10 inches long emerge in the spring and die by early summer as the plant goes dormant. In the fall, flower stems stretching around 6 to 10 inches high pop up from the ground, with star-shaped blooms.
Why does my Colchicum autumnale roots have rot?
If left untreated, root rot on your Autumn crocus (Colchicum autumnale) 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 Autumn crocus 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.
When you understand the root of the issue, the solution makes perfect sense. The majority of the time, it is caused by the Colchicum autumnale 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 Autumn crocus have leaf spots?
If your plants exhibit symptoms like rapid color changes in the leaves or leaves that wilt or droop, we give you all the information you need to recognize them and rescue your plants. For owners of Autumn crocus, this kind of illness is among the most distressing.
Why are my Autumn crocus 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:
Here are some signs of yellowing caused by the many deficiencies on the Colchicum autumnale in question:
- The first symptom of a magnesium deficiency is yellow patches between leaf veins on elder leaves. The leaf’s core turns yellow while the veins stay green. The edges of the leaf 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.
- Potassium deficiency shows itself when leaf edges turn bright yellow, but the inner leaf stays green. Older leaves show symptoms first, and leaf edges soon turn brown.
- 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 Autumn crocus sunburned?
You can easily tell if your Autumn crocus (your Colchicum autumnale) has a sunburn. In this case, your plant will change color, starting to turn yellow or white, much like it does on us.
The leaves of your Autumn crocus can also change color in case it gets too much water or not enough light, as we saw above.
However, there is a way to tell if it is sunburn; look at the bottom of the yellow leaves, the ones that have a shaded area closer to the root, if this area stays greener, it is probably sunburned, not something else.
Why are my Autumn crocus leaves turning brown?
Most of the time, leaves of a Autumn crocus that turn brown is a sign that your plant has been sunburned, it has probably been exposed to too much direct sunlight. Don’t panic, your plant probably won’t die from this, but its growth will take a hit.
Should I leave my Colchicum autumnale in direct sunlight?
No! If your Colchicum autumnale (or Autumn crocus) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Autumn crocus is in such a state!
As stated in the paragraph above, the cure is straightforward: simply position your plant’s Autumn crocus 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 Colchicum autumnale leaves drooping or wilting ?
In most cases, this happens when your Colchicum autumnale lacks water. This is especially the case for large plants, naturally they need more water than others.
An easy way to know if your Colchicum autumnale 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!
In order to ensure that the roots of your plant receive the water’s benefits, you must first moisten the soil in the container if it is absolutely dry. One common error is to immediately drown the Autumn crocus after a dry period in the belief that it requires 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 Colchicum autumnale
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 Colchicum autumnale.
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 is also a good idea to keep your Colchicum autumnale 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 Colchicum autumnale near a source of hot (or cold) air such as A/C units, radiators or the like.
Keep your Autumn crocus 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 Autumn crocus, this would be a true descent into hell, and it would also appease the pests.
Take a microfiber cloth and gently massage the plant’s leaves to get rid of the dust. Use a damp cloth to make dust removal easier, but avoid using corrosive materials 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.
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!)
