NOTE: In this article, Schubert’s allium and Allium schubertii may be used interchangeably; in fact, Allium schubertii is the botanical name for Schubert’s allium.
Allium schubertii, also known as Schubert’s allium or ornamental onions, is one of several allium species grown as ornamental landscape plants. These alliums are not a good substitute for table onions. Schubert’s allium is a bulb that produces a low cluster of strap-like foliage in the early spring and then sends up a tall flower scape supporting a flower cluster.
While it has the same globe-shaped flowers found on other ornamental onions, the blooms on this species have a very striking resemblance to exploding fireworks. The flower heads are large globe-shaped clusters of 100 or more tiny star-shaped flowers, and the entire globe can be as much as 18 inches across. Schubert’s allium is an easy plant to grow, making it a favorite among beginning gardeners.
Why does my Allium schubertii roots have rot?
Root rot on your Schubert’s allium (Allium schubertii) can be dangerous if left untreated. In order to keep your plant alive, we strongly suggest that you follow our advice if the signs start to show: blackened and mushy roots.
Why does my Schubert’s allium have gray mold spots?
Gray mold spots are a specific fungus that regularly harms flowers and spreads swiftly. If you notice any brown (or gray) spots, this fungus is probably to cause. You risk your plant dying if you ignore these warning indications.
Our Solution
The answer is obvious once you recognize the cause of the problem. Most frequently, it results from the Allium schubertii 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 Schubert’s allium have leaf spots?
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 Schubert’s allium owners.
Why are my Schubert’s allium leaves turning yellow?
This is probably the most common problem in the gardening world, yellowing leaves. There are 2 main reasons for this phenomenon, overwatering, or a lack of nutrients.
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 Allium schubertii 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.
- Yellowing between leaf veins is another sign of iron shortage, but young leaves on plant tops and branch tips are initially affected.
- 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.
- Nitrogen deficiency shows up as a general yellowing. Older, inner leaves turn yellow first. As it progresses, yellowing moves outward, eventually reaching young leaves, too.
Our Solution
You only need to act in accordance with the symptoms listed above. You can address a potassium or nitrogen deficiency by buying a particular soil, and a gardening store consultant will be able to advise you on how to do that. Furthermore, you can also limit how frequently you water your plants.
Is my Schubert’s allium sunburned?
It is simple to determine whether your Schubert’s allium (your Allium schubertii) has sunburn. Your plant will change color in this instance, beginning to turn yellow or white, much like it does on us.
As we saw above, if your Schubert’s allium receives too much water or not enough light, the leaves may also change color.
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 Schubert’s allium leaves turning brown?
Most of the time, leaves of a Schubert’s allium 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 Allium schubertii in direct sunlight?
No! Don’t leave your Allium schubertii (or Schubert’s allium) 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 Schubert’s allium out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.
Why are my Allium schubertii leaves drooping or wilting ?
This typically occurs when your Allium schubertii gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.
You may quickly determine if your Allium schubertii 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
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 Schubert’s allium 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 Allium schubertii
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 Allium schubertii 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 Allium schubertii near a source of hot (or cold) air such as A/C units, radiators or the like.
Keep your Schubert’s allium 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 Schubert’s allium and would also satisfy 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.
If your pots don’t already have holes in them, you can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the meantime. This will assist in creating a channel and keep the water from pooling there for an extended period of time, protecting the roots from decay.
