Water:
Originating from moderate climates, japanese photinia is drought-tolerant and prefers consistent soil moisture with drying between waterings. Water every 2-3 weeks and consider mulching to retain moisture, especially since japanese photinia is often grown outdoors due to its size and growth habits.
Fertilize:
For optimal health, japanese photinia needs balanced fertilizers, ideally a 10-10-10 mix applied early spring and again in late summer. Adjust nutrient levels for growth stages, using phosphorus-rich fertilizer during blooming. Water thoroughly after application to aid absorption, and always follow safety precautions while handling.
Pruning:
Japanese photinia features glossy leaves and vibrant red growth, benefiting from annual pruning in late spring post-bloom. Trim dead branches and overcrowded areas for better air circulation. Removing spent flowers increases vigor, enhancing aesthetics and promoting healthier growth.
Propagation:
Japanese photinia is best propagated using cuttings from healthy, semi-hardwood stems cut at a 45-degree angle. Place in a well-draining potting mix with adequate moisture and warmth, and provide indirect light to promote root development while avoiding scorch.
