A Friendly Guide to Fighting Rust Disease on Your Plants

Rust disease shows up as powdery orange, yellow, or brown spots on the underside of leaves. It spreads through spores carried by wind or water, especially in damp conditions. If left unchecked, it can weaken plants and stunt growth.

To prevent rust, avoid overhead watering and make sure your plants have plenty of space and airflow. Remove and destroy infected leaves, and clean up fallen debris regularly. Crop rotation can also help break the disease cycle.

Rust is a common fungal disease that causes orange or brown spots on leaves. It looks bad and can weaken your plants over time. Start by trimming away affected leaves and disposing of them. Don’t water the leaves—water the base of the plant instead. Good airflow is key, so don’t plant too close together. If rust keeps coming back, try a baking soda spray: mix one teaspoon of baking soda in a quart of water with a few drops of dish soap. Spray weekly until symptoms fade. These simple steps help control rust without using harsh chemicals.
