NOTE: The terms Beaked hazelnut and Corylus cornuta are identical in this text; in reality, Corylus cornuta is Beaked hazelnut’s biological word.
The native shrubCorylus cornuta is found throughout much of the United States and southern Canada. The shrub can be found in the forest understory or along the forest edges.
In the fall, the beaked hazelnut bears acorn-like nuts that are rich in nutrition and play an important role in the food source of many wildlife species. The upright understory shrub is best used as a background shrub or as a filler plant. This shrub is low-maintenance and nut-bearing.
Why does my Corylus cornuta roots have rot?
Root rot on your Beaked hazelnut (Corylus cornuta) 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 Beaked hazelnut have gray mold spots?
A particular fungus known as gray mold spots spreads quickly and frequently damages flowers. This fungus is probably to blame if you see any brown (or gray) spots. If you disregard these warning signs, your plant could die.
The solution is quite logical when you know the cause of the problem. Most of the time, it is due to overwater of the Corylus cornuta. We advise you to remove the infected parts of the plant, cut off the infected roots and leaves, then repot your plant using sterile potting soil and a clean pot.
Why does my Beaked hazelnut have leaf spots?
This type of disease is one of the most frustrating for Beaked hazelnut 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 Beaked hazelnut 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.
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 Corylus cornuta 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.
- Another indicator of iron deficiency is yellowing between leaf veins, but young leaves on plant tops and branch tips are first affected.
- The newest leaves are first affected by sulfur deficiency, rendering them completely 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.
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 Beaked hazelnut sunburned?
It is simple to determine whether your Beaked hazelnut (your Corylus cornuta) 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 Beaked hazelnut 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 Beaked hazelnut 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 Corylus cornuta in direct sunlight?
No! If your Corylus cornuta (or Beaked hazelnut) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Beaked hazelnut is in such a state!
As stated in the paragraph above, the cure is straightforward: simply position your plant’s Beaked hazelnut 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 Corylus cornuta leaves drooping or wilting ?
In most cases, this happens when your Corylus cornuta lacks water. This is especially the case for large plants, naturally they need more water than others.
Whether your Corylus cornuta 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 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 Beaked hazelnut 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 Corylus cornuta
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 Corylus cornuta.
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’s also a good idea to keep your Corylus cornuta 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 Corylus cornuta away from radiators, air conditioners, and other sources of hot or cold air.
Keep your Beaked hazelnut 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 Beaked hazelnut, 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 tend to overwater, you need to pay attention to your drainage, and we advise choosing a saucer and a pot with drainage holes if they are not already there.
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!)
