Troubleshooting
Impatiens balsamina problems — and how to fix them
Impatiens balsamina (Impatiens balsamina) 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.
Downy and powdery mildew
Like other impatiens, balsam can suffer mildew in crowded, damp conditions, with yellowing or white-coated leaves. Space plants for airflow, water at the base and avoid wetting foliage.
Wilting in heat or drought
Plants flag quickly when the soil dries out, especially in full sun. Keep soil evenly moist, mulch around them and provide light afternoon shade in hot climates.
Self-seeding and explosive pods
Ripe seed pods burst when touched, scattering seed widely, so plants can pop up unexpectedly the next year. Remove pods before they ripen if self-seeding is unwanted.
Aphids, spider mites and slugs
Sap-suckers attack soft growth in dry heat, while slugs chew young seedlings. Rinse foliage and use insecticidal soap for pests; protect seedlings from slugs.
