Buying Guide: Powdery Mildew Resistant Zucchini Seeds
- Disease resistance vs. yield: Look for explicit mentions of powdery mildew resistance, disease tolerance, or robust foliage. A variety may be labeled disease resistant but still respond to seasonal stress. Choose seeds with strong foliage health and consistent fruit set.
- Growth habit and space needs: Bush types are compact and ideal for small plots or containers; vining Tromboncino needs trellising but can maximize vertical space. Match the habit to your garden layout.
- Maturity timing: Shorter days-to-maturity means multiple harvests in a single growing season, which helps offset any disease pressure. Plan for succession planting in warm regions.
- Open-pollinated vs. hybrid: Open-pollinated varieties allow seed saving for future seasons, while hybrids may offer uniform vigor but seed saving results can be unpredictable.
- Growing conditions: Ensure soil is well-drained, consistently moist, and receives full sun for best results. Airflow around plants reduces mildew risk.
- Storage and cooking: Consider flavor, texture, and harvest size. Some varieties produce many small fruits, while others yield fewer larger ones. Pick according to your preferred use.
