What is the best time to plant late season potatoes in California?

The best time to plant late season potatoes in California varies by region due to its diverse climate. Here's a general guide:

Southern California (Los Angeles, San Diego):

- Late September to early October: This allows for the potatoes to mature before the hottest summer months.

Central California (San Francisco Bay Area, Sacramento):

- Mid-September to early October: Similar to Southern California, this timing allows for cooler weather during the growing season.

Northern California (Redding, Eureka):

- Late September to early October: This time frame gives potatoes a chance to establish before the colder winter months.

Factors to consider:

* Variety: Some potato varieties are more heat-tolerant than others. Check the specific variety you plan to plant.

* Soil temperature: Aim for soil temperatures around 60-70°F (15-21°C) for optimal germination.

* Weather: Avoid planting during prolonged periods of hot weather or heavy rainfall.

* Local climate: Consider your specific microclimate and any potential frost dates.

It's always best to check with your local nursery or extension office for the most up-to-date planting recommendations for your specific area. They can provide tailored advice based on local weather patterns and soil conditions.
