NOTE: Hawthorn may be referred to as Crataegus spp. in this article, in fact, those are the same plants, Crataegus spp. is the botanical name for Hawthorn.
Some of the most pleasing small trees and shrubs that gardeners and landscape designers can put into a landscape are gifts from the Crataegus family. It is the perfect size for smaller settings as a single specimen and packs an eye-pleasing punch when grouped together in larger gardens.
Why does my Crataegus spp. roots have rot?
If left untreated, root rot on your Hawthorn (Crataegus spp.) 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 Hawthorn have gray mold spots?
A particular fungus that frequently affects flowers and spreads quickly is known as gray mold spots. This fungus is most likely to blame if you see any brown (or gray) spots. Don’t ignore these signs because doing so could cause your plant to die.
When you understand the root of the issue, the solution makes perfect sense. The majority of the time, it is caused by the Crataegus spp. 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 Hawthorn 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 Hawthorn owners.
Why are my Hawthorn leaves turning yellow?
In the world of horticulture, yellowing leaves are undoubtedly the most common problem. The two main causes of this problem are overwatering and a lack of nutrition.
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:
Each deficiency produces a different yellowing on the Crataegus spp. in question, here’s how to spot them:
- 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.
- Yellowing between leaf veins is another sign of iron shortage, but young leaves on plant tops and branch tips are initially affected.
- 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 broad yellowing indicates a nitrogen deficiency. Yellowing starts with older, inner leaves. Yellowing spreads as it advances, eventually touching new leaves as well.
You only need to respond to the signs mentioned above. A gardening store expert will be able to provide you advice on how to purchase a specific soil to treat a potassium or nitrogen deficiency. Additionally, you can reduce how often you water your plants.
Is my Hawthorn sunburned?
You can easily tell if your Hawthorn (your Crataegus spp.) 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, the leaves of your Hawthorn can also change color if it receives too much water or insufficient light.
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 Hawthorn leaves turning brown?
Most of the time, leaves of a Hawthorn 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 Crataegus spp. in direct sunlight?
No! Don’t leave your Crataegus spp. (or Hawthorn) in the sun if it displays the symptoms mentioned above; that’s why it’s in such a bad situation.
The remedy, as said in the paragraph above, is simple: just move your plant’s Hawthorn out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.
Why are my Crataegus spp. leaves drooping or wilting ?
In most cases, this happens when your Crataegus spp. lacks water. This is especially the case for large plants, naturally they need more water than others.
Whether your Crataegus spp. 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.
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 Hawthorn after a dry period in the belief that it requires 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 Crataegus spp.
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 Crataegus spp..
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 Crataegus spp. 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 Crataegus spp. close to air conditioners, radiators, or other sources of hot or cold air.
Keep your Hawthorn 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 Hawthorn, this would be a true descent into hell, and it would also appease 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.
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.
