Camellia is losing leaves.
Leaves look healthy not brown or yellow. It started bloom few weeks ago and at the same time started losing leaves. Is it natural? Or do I need to do something? Another camellia with flowers is normal. But it started blooming a bit later. Do I expect the same thing? Thanks. Huge help.
That's not much information to go on for a remote diagnosis. We would need photos, your location (what's Sw5?), the type of camelia and age, previous history of growth and blooming, and more about your soil fertility and water managment. Any recent disturbance of soil nearby, root cutting, compaction or paving, undergound water or gas leak?
Without background information, I can only recommend to consider mulching, fertilization and good water management.
