A Simi Valley Planting Calendar
Timing is just as important as seed selection. In Simi Valley, warm-season crops such as tomatoes, peppers, beans, squash, and melons are generally planted in spring after the risk of cold nights has passed. Cool-season crops including lettuce, spinach, carrots, broccoli, and peas thrive when planted in fall and grown through winter. California native wildflower seeds are best sown in fall so that winter rains can help them germinate. Mulching, drip irrigation, and afternoon shade during summer heat waves help seedlings establish successfully in the valley's warm inland climate.
