NOTE: In this article, Mock orange and Philadelphus coronarius may be used interchangeably; in fact, Philadelphus coronarius is the botanical name for Mock orange.
The mock orange has a dense, rounded growth habit and loses its leaves in the fall. The leaves are dark green and oval. It has showy, cup-shaped, four-petal flowers in the late spring and early summer that are roughly 1 to 2 inches across. Many gardeners grow this shrub because the flowers are very fragrant.
The shrub’s common name is mock orange, because the flowers are said to resemble orange blossoms. The shrubs have a high rate of growth and can grow up to 2 feet a year. They can be planted in the spring, but only in the early fall.
Why does my Philadelphus coronarius roots have rot?
Root rot on your Mock orange (Philadelphus coronarius) can be fatal if not treated with care. For this reason, we strongly recommend that you follow our guide to keep your plant alive if the symptoms occur: Root soft and blackened.
Why does my Mock orange 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.
The answer is obvious once you recognize the cause of the problem. Most frequently, it results from the Philadelphus coronarius 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 Mock orange 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 Mock orange owners.
Why are my Mock orange 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.
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:
Here are some signs of yellowing caused by the many deficiencies on the Philadelphus coronarius 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.
- 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.
- 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 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.
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 Mock orange sunburned?
You can easily tell if your Mock orange (your Philadelphus coronarius) 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, if your Mock orange receives too much water or not enough light, the leaves may also change color.
The bottom of the yellow leaves with a shaded area closer to the base can be examined to determine if they have been sunburned. If this part remains greener, the yellow leaf is most likely sunburned and not something else.
Why are my Mock orange leaves turning brown?
The classic sign that a plant has been overexposed to direct sunlight and sunburned is the development of browning leaves. Rest assured that while this may probably save your plant from dying, it will adversely affect its growth.
Should I leave my Philadelphus coronarius in direct sunlight?
No! Don’t leave your Philadelphus coronarius (or Mock orange) 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 Mock orange out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.
Why are my Philadelphus coronarius leaves drooping or wilting ?
When you become dehydrated, this usually happens. Large plants are more vulnerable since they need more water on a regular basis than smaller plants.
You may quickly determine if your Philadelphus coronarius plant needs water by under-weighing its pot; if it seems light, the soil and roots are probably fairly dry and require 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 Mock orange 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 Philadelphus coronarius
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 Philadelphus coronarius.
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 Philadelphus coronarius 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 Philadelphus coronarius away from radiators, air conditioners, and other sources of hot or cold air.
Keep your Mock orange 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 Mock orange and would also satisfy 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 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.
You can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the interim if your pots don’t already have holes in them. This will help to form a channel so that the water doesn’t pool there for too long (preventing the rot of the roots!).
