Rust disease is a common problem that affects many plants, especially in warm climates like Zone 10. Recognizing the signs early and taking proper action can save your plants and keep your garden healthy.
What Is Rust Disease?
Rust disease is a fungal infection caused by various species of rust fungi. It appears as orange, yellow, or brown pustules on the leaves, stems, or fruits of plants. Rust weakens plants, reduces growth, and can lead to defoliation if not managed promptly.
Common Signs of Rust Disease

- Yellowing or browning of leaf tissue
- Stunted plant growth
- Spots on stems and fruits
- Premature leaf drop

Prevention is the best approach to managing rust. Here are some effective strategies:
- Choose resistant plant varieties when possible
- Ensure good air circulation around plants
- Water plants at the base to avoid wetting foliage
- Maintain proper spacing between plants
