I've had success with similar selections in zone 8. For soil, leaning toward a well-draining medium with a pH around 5.5 to 6.5 really works best—amending with organic matter like leaf mold can help. I've found that while they can take more sun than Japanese camellias, a bit of afternoon shade prevents leaf scorch during hotter days. Watering should be regular yet moderate—enough to keep the soil moist without being waterlogged. Consider a balanced, acid-loving fertilizer in early spring, then maybe a light feeding after blooming. Pest-wise, watch for scale and spider mites; in my experience, proper air circulation and a timely insecticidal soap response work well. Happy gardening, and I look forward to hearing about your Yuletide blooms!
