Callery pear: Diseases and Remedies (Prunus calleryana)

NOTE: In this article, Callery pear and Prunus calleryana may be used interchangeably; in fact, Prunus calleryana is the botanical name for Callery pear.

The tree was named after Joseph-Marie Callery, who sent the first specimen from China to Europe in the 1800s. The Callery pear was introduced to the US in the mid 1900s and was promoted as a desirable tree for planting due to it being inexpensive and fast-growing. The Callery pear is not a true pear tree, but it does produce small fruits in the autumn.

It has glossy green leaves that turn multiple colors in the fall, making it a perfect accent tree for seasonal color. If there is an early frost, the leaves on the tree may not be as bright. The Callery pear can be found in Vietnam, Korea, and China.

Why does my Callery pear 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.

Our Solution

The answer is obvious once you recognize the cause of the problem. Most frequently, it results from the Prunus calleryana 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 Callery pear have leaf spots?

Leaf This type of disease is one of the most frustrating for Callery pear 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 Callery pear 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 Prunus calleryana 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.
  • Another indicator of iron deficiency is yellowing between leaf veins, but young leaves on plant tops and branch tips are first affected.
  • Sulfur deficiency starts with the newest leaves, turning them yellow throughout.
  • 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 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 Callery pear sunburned?

It is simple to determine whether your Callery pear (your Prunus calleryana) has sunburn. Your plant will change color in this instance, beginning to turn yellow or white, much like it does on us.

Sunburned

As we saw above, if your Callery pear receives too much water or not enough light, the leaves may also change color.

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.

Why are my Callery pear 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 Prunus calleryana in direct sunlight?

No! If your Prunus calleryana (or Callery pear) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Callery pear is in such a state!

Our Solution

As explained in the paragraph above, the solution is simple, just place your Callery pear in a place where the light does not reach it directly, in this way and with a correct watering, your plant should resume its life rather quickly.

Why are my Prunus calleryana leaves drooping or wilting ?

This typically occurs when your Prunus calleryana gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.

Drooping

An easy way to know if your Prunus calleryana 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!

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 Callery pear 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 Prunus calleryana

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.

You can tell if your plant needs water by touching the soil; if it still feels damp, it’s usually preferable to wait a few more days.

Always keep temperatures stable

It’s also a good idea to keep your Prunus calleryana 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 Prunus calleryana away from radiators, air conditioners, and other sources of hot or cold air.

Keep your Callery pear Dust-Free

This one is about houseplants. Your indoor plants’ leaves get dusty just like your furniture does. The problem is that this might prevent photosynthesis from beginning, which would result in the plants gradually losing their color.

This would be a true journey into hell for your Callery pear 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 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!)
