Q. What is wrong with my photinia?
The main culprit among photinia bush diseases is Entomosporium mespili, the fungus that causes photinia leaf spot.
Q. Why are the leaves falling off my photinia?
Being too dry for too long, or too cold in winter, are other stress factors which can also stimulate Photinias to drop more of the older leaves and thereby necessitate a one-off restorative pruning, so occasional watering in long periods of dry weather (I use the washing-up water!) will help with that potential problem …
Q. How do you revive a photinia?
The easiest method of photinia rejuvenation is to cut back the entire shrub at one time. Photinia tolerates cutting back to about 6 inches (15 cm.) above the ground. The problem with this type of pruning is that it leaves a gap and ugly stump in the landscape.
Q. Why is my red tip photinia turning yellow?
Red-tip photinia is prone to yellowing of the leaves in between the leaf veins, a condition called chlorosis, which is caused by iron deficiency. Chlorosis is particularly likely in alkaline soil, which is common in the western part of the United States. Inspect the plant for iron chlorosis symptoms.
Q. How do you treat leaf spot disease?
- Live with the disease. Most trees tolerate leaf spots with little or no apparent damage.
- Remove infected leaves and dead twigs.
- Keep foliage dry.
- Keep plants healthy.
- Use fungicides if needed.
- Replace the plant.
Q. How often should you water a Photinia?
It rarely needs watering except in severe drought and will grow quite happily on average ground without the need of additional feeds. It will need pruning once or twice a year to keep it in shape and to size. For younger plants up to two years old, water if conditions become dry.
Q. Why are the leaves on my Red Robin turning black?
Photinia shrubs sometimes contract a disease called Photinia leaf spot or Photinia black spot. Leaves are dotted with black spots that slowly spread until leaves wilt and fall off.
Q. What does chelated iron do for plants?
The chelates work as a carrier to allow the iron to be absorbed by the plant’s roots, even in alkaline soil. In plants where chelates are not naturally released, chelated iron can be used as a supplement to treat and prevent iron deficiencies ( University of Florida Cooperative Extension).
Q. Are there any problems with the red tip photinia?
Red tip photinia (Photinia fraseri) are particularly susceptible to root fungal diseases in poorly drained soil. Damage from root diseases can weaken plants making them more susceptible to problems such as leaf spot fungus. Fallen leaves can be removed, as they are a potential source of future infections,…
Q. Are there any problems with Indian hawthorn Photinia?
First of all, understand that neither photinia nor Indian hawthorn can stand “wet feet” or tolerate poor drainage. Red tip photinia (Photinia fraseri) are particularly susceptible to root fungal diseases in poorly drained soil. Damage from root diseases can weaken plants making them more susceptible to problems such as leaf spot fungus.
Q. What kind of diseases do Photinia bushes get?
Although photinia plants are easy to care for, they are vulnerable to some photinia diseases such as leaf spots, fire blight, powdery mildew and crown and root rots, advises the University of California Extension.
Q. Why are the leaves on my Photinia turning brown?
Root and crown rots caused by Phytophthora fungi is one of the common photinia diseases. Symptoms of infection include wilted and discolored leaves, stunted growth and premature defoliation. You may also see streaks or cankers on the trunk, with a brown or dark gray discoloration beneath the bark.
