Red-tipped Photinia x fraseri and Photinia serrulata

COMMON RED-TIPPED PHOTINIA x. FRASERI
You see it everywhere in the South, used as a screening hedge or all by itself. Some folks love them and have no complaints but photinias aren't recommended anymore because they're so often afflicted with leaf spot fungal disease, especially in the warmer regions.
Details
- Grows to 15 feet tall and wide.
- Hardy to Zone 7 (and 6, with protection).
- Grows fastest and is less disease-prone in full sun.
- The varieties 'Indian Princess' and 'Red Robin' are reported to have better resistance to disease. 'Red Robin' is also more compact.
- Very drought-tolerant.
- Leaf spot fungal disease can appear in spring and fall when the weather is cooler, especially when it's rainy.
Care
- To improve resistance to disease, prune for create better air circulation by thinning, and avoid shearing. Pruning is best done in winter when the shrubs are dormant.
- Also, siting photinia where air circulation is best helps (though that doesn't help your already-huge shrubs, does it?) This means not planting them too close to each other, as is often done to create hedges.
- Another prevention tip is to avoid getting water on the leaves. Water the root zone at ground level only.
- Likes moderately acidic soil, so feeding with Hollytone is suggested, though not in summer.
AND A BETTER PHOTINIA
Photinia serrulata, from China, is increasingly recommended as an alternative to red-tipped photinia because of its resistance to leaf spot. Its new growth is more copper-colored, so less spectacular than the red-tip.
Details
-
Listed as growing to 15 by 12 feet, it's also been known to grow to 30 feet tall (in full sun), so keep that in mind.
- A "moderate to rapid" grower.
- Also, quite drought-tolerant.
- Happy in full sun to part shade.
- Also hardy to Zone 7, or Zone 6 with protection.
Care
-
This photinia is still somewhat vulnerable to another fungal disease - powdery mildew - when it's grown in shade, so use the same care techniques listed above.
