Gardening in Solano County, California: Tomatoes, Nurseries, and Resources

Transitioning from Maryland to California Gardening

Moving from the Mid‑Atlantic to Solano County (USDA zones 9a/9b) brings a longer growing season, mild winters, and dry summers. Here’s what you need to know.

Tomatoes

• When to plant: Start seeds indoors in January–February; transplant outdoors after last frost (mid‑March). A second crop can be started in July for fall harvest.
• Year‑round potential: With protection (row covers, cold frames), you can grow tomatoes nearly year‑round, but summer heat may reduce fruit set. Choose heat‑tolerant varieties.
• Watering: Consistent, deep irrigation is essential; drip systems work best.

Buying Plants

• Local nurseries: Best for climate‑adapted varieties and compliance with California’s strict agricultural regulations.
• Mail‑order: Many reputable companies (e.g., White Flower Farm) ship to California but must adhere to quarantine rules. Check each vendor’s shipping policy.
