Begonia 'Jurassic Watermelon' problems — and how to fix them
Begonia 'Jurassic Watermelon' (Begonia rex-cultorum 'Jurassic Watermelon') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Powdery mildew
White powdery patches from wet leaves and poor airflow. Water at the soil, improve air circulation, and avoid wetting the foliage.
Crispy leaf edges
Low humidity or fertiliser salt buildup. Raise humidity, dilute feed, and flush the soil occasionally.
Rhizome or root rot
Overwatering or a dense mix rots the shallow rhizome. Use an airy mix and let the surface dry between waterings.
Faded leaf colour
Too little light mutes the watermelon markings. Move to brighter indirect light, out of direct sun.
