Pelargonium 'Mabel Grey' problems — and how to fix them
Pelargonium 'Mabel Grey' (Pelargonium 'Mabel Grey') 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.
Tall, bare legginess
This cultivar naturally grows upright and can become leggy. Pinch and prune hard in spring to force lower branching and a fuller plant.
Weak scent in low light
Insufficient sun and overfeeding dilute the prized lemon fragrance. Maximise direct light and avoid heavy nitrogen feeds.
Pelargonium rust
Brown pustules ringed by yellow appear on leaf undersides in damp, crowded conditions. Remove affected leaves, improve airflow and keep foliage dry.
Root rot from overwatering
Soggy compost rots the fleshy stem base. Use gritty mix, water only when the top of the compost is dry and ensure free drainage.
