Treating Rust on Indoor Miniature Roses: Cultural Fixes and Fungicide Options

Why Indoors Fails

Dry household air weakens minis → disease. Rust is hard to eradicate.

Protocol

1. Pick off ALL leaves.
2. Cut plant back by half.
3. Fertilize (any houseplant food).
4. Spray Funginex weekly for 1 month.
5. Repot into larger pot with fresh potting soil (cool roots).
6. Mist daily after spraying.

Or Just Replace

If no sentimental value, start fresh with a new mini in a big pot — far fewer problems.
