- Hot Summers: Summer temperatures often exceed 90°F (32°C), necessitating shade and irrigation for some plants.
- Moderate Rainfall: Precipitation varies but generally provides sufficient moisture for most plants.
- Sunshine: Abundant sunlight promotes healthy growth and extended growing seasons.
Seasonal Weather Patterns
Understanding seasonal patterns helps in planning planting and harvesting. In Zone 9, the seasons are generally as follows:
Spring
Spring begins around March and lasts until May. Temperatures gradually rise, and the risk of frost diminishes. This is an ideal time for planting vegetables like tomatoes, peppers, and herbs.
Summer
Summer, from June to August, is hot and often dry. Watering and shade are crucial for many crops. Crops like eggplants, okra, and melons flourish during this time.
Fall
Fall, from September to November, offers cooler temperatures and is suitable for planting cool-season crops such as lettuce, broccoli, and carrots. It’s also a good time to prepare soil for winter planting.
