5 Proven Ways for Fixing Photinia Leaves Drooping

Photinia Leaves Dropping problem Fixing

1. Improper Watering

Watering issues are the most common causes of photinia plant leaf drooping. Many gardeners think that watering is not a major factor. They water the plants at their convenience. But that is a big mistake.

If you don’t water your photinia plants properly, dehydration occurs. As a result, your plant will fail to cover the demand for water for each part of its body. And the first victims are leaves. 

Due to lack of watering, the leaves of photinia plants first turn yellow, then become curly and drop.

Control Measure

Photinia prefers watering once a week. But there’s an exception for new plants. You have to water them regularly for the first two years after planting.

Deep watering is highly recommended for photinia. You have to ensure two and a half inch watering. But a moisture test is a must before watering. Use a moisture meter for that (Our Pick: SONKIR Soil pH Meter, MS02 3-in-1 Soil Moisture/Light/pH Tester)

If you have no then a dry tiny stick is enough. Put it 2-3 inches deep in your pot soil. Then turn backward. If it seems wet there is no need for watering. Apply deep watering if the stick is dry.

Photinia plants do not need watering during the rainy season. Watering may be necessary, though, if it grows into a shrub on a wall where rainwater cannot reach.

2. Dry Soil

Dry soil has a strong correlation with photinia plant leaf loss. If you plant your photinia in soil that fails to hold enough water, it is dangerous for your plant.

Plants often suffer from dehydration in dry soils. In addition, dry soil also fails to supply nutrients. As a result, the plant cannot fully perform its normal biochemical functions. That is why problems such as falling leaves and weakening of the tree are evident.

Again dry soil does not improve air circulation. So in dry soil photinia plants never get enough oxygen and due to insufficient oxygen, your plant’s biochemical processes such as photosynthesis don’t occur. As a result, leaf loss happens.

Control Measure

You must ensure good air-circulating soil for photinia plants. Earthworms can be a good option for increasing oxygen levels in your pot soil. It will increase the soil quality along with the oxygen supply. Not possible? Then you can also use an aerator.

It is important to choose soil that can hold enough water. By using organic compost, manures, or other stable organic materials you can easily increase the water-holding capacity of your pot soil.

Additionally, photinia plants prefer both alkaline and somewhat acidic soil. Soil pH should be between 6 and 7. You should check the pH level regularly by using a pH meter.

3. Lack of Sunlight

Your photinia plant won’t be able to complete its most vital photosynthesis process if you set it in a dark area and it doesn’t receive enough sunlight.

Your plant’s internal body system will subsequently collapse, causing the leaves to dry out, turn brown, and drop.

If your plant is in the shade and the leaves begin to drop before turning brown, insufficient sunlight must be the main problem.

Control measure

The ideal amount of sunlight for photinia plants is 8 to 9 hours per day. You must pick a location where your plant will receive enough sunshine. It can be north or east-facing corner at your home.

Partial shade is also tolerable, but if you want vibrant foliage and flowers, make sure there is enough sunlight.

If you keep photinia indoors, you must put it in sunny places. Perhaps there isn’t enough sunlight in your room. then you can utilize an artificial lighting system.

4. Pruning Mistake

Timing and method are very important for pruning. Inappropriate pruning and not pruning at the right time can cause your photinia plant to lose leaves.

If you over-prune without following proper procedures, your plant will lose some of its essential parts. Which will hinder your plant’s normal growth and other nutrients. As a result, problems like leaf fall, and leaf discoloration will occur.

Again, if your pruning time is not correct, the plant will experience unusual conditions and due to stress problems such as leaf drops will occur.

Control Measure

Photinia plants prefer very little pruning. Basically, summer and late spring are the right times for pruning. But you should refrain from pruning in August and September i.e. before winter.

You should always use a sharp blade for pruning. But the blade needs to be changed if it loses its sharpness.  

Long-handled knives are also useful for pruning. A maximum of one to one and a half centimeters of pruning can be done at a time. Try to prune overgrown branches first.

5. Fungal Disease

One of the most common fungi that infect Photinia plants is Entomosporium mespili. Their presence is a really serious problem and is responsible for drooping. 

Small dots on the inside of the leaves are the disease’s initial symptom, and subsequently, lesions develop with reddish-brown edges with a grey center and leaf loss. 

When the infection spreads, plants die by mid-summer, and secondary infection frequently results in significant illness in new leaves. This fungus illness requires ongoing management and is very challenging to control once it has taken hold.

Control Measure

A temporary fix might be to clean up the infected area and eliminate it. The likelihood of infecting further leaves will be significantly decreased if the affected area can be removed soon.

Since treating this condition is difficult, prevention should have priority. Entomosporium fungus can be avoided on your photinia plant by following a few easy steps.

You must be certain that the seeds are healthy before planting. Based on the plant’s requirements, the planting location should be chosen. Never use too much water. Avoid planting multiple trees at once if possible. The soil in your garden should be kept as dry as you can.

As long as there is dry weather, begin using effective fungicides like chlorothalonil and myclobutanil in the early spring. Spray all of the branches and leaves thoroughly. An organic anti-fungal spray is an additional option.

Frequently Asked Questions (FAQ’s)

Q: Is it normal for Photinia plants to lose leaves?

Ans: Photinia plants are typically evergreen, and leaf loss is not a normal occurrence. However, shedding a few older leaves is natural as new growth emerges.

Q: Can underwatering cause leaf loss in Photinias?

Ans: Yes, insufficient watering can cause drought stress, resulting in leaf drop. It is important to water Photinia plants adequately, ensuring that the soil is consistently moist but not waterlogged.

Q: Are there any common pests that cause Photinia leaf loss?

Ans: Photinias can be susceptible to pests like spider mites, aphids, and scales. These pests can cause leaf discoloration, wilting, or defoliation if left untreated.

Q: Do Photinia plants lose leaves during winter?

Ans: Photinia plants are generally evergreen, but in colder climates, they may experience some leaf drops during winter. This is a natural response to colder temperatures and is not usually a cause for concern.

Q: How fast do photinia plants grow?

Q: What is the best time for pruning photinia plants?

Ans: Summer and late spring are ideal times to prune photinia plants.  You must avoid autumn and prune properly.
