My Camellia changii is losing its color and getting this aspects so sad. Is it lack of fertilizer or, conversely, excess? I live in Sintra, Portugal, and the climate is excellent for camellias in general.
Is there anyone who can help me?
The soil is acidic, the fertilizer I am using is NPK 5-6-13 + 4% MgO a tablespoon every 30 days, with good drainage and the watering is drop-by-drop. This year the winter in Portugal was very rainy and mild temperatures, only two or three days with minimum temperatures of 3ºC (37.4 ℉)
