Camellias are relatively unfussy and problem-free shrubs, but they can develop camellia leaf gall, a unique and odd-looking disease. Here’s how to identify it. Symptoms are a fleshy thickening of the leaf, sometimes with a distinct “orange peel” texture. The affected leaves are also pale green in color, occasionally blushed with pink. It’s usually seen on new growth in spring and affected leaves generally stand out like a sore thumb making ID pretty easy.
