Fall is the perfect time to refresh your garden and keep it growing into the winter. You want to choose the right crops and the best location; choose cold-weather protection best suited to your needs and know your frost dates.
Cool-season crops thrive in cooler temperatures, and several have shorter seasons than warm-season crops. Cool-season vegetables grow best between 45 and 55 degrees and 55 to 75 degrees, and most mature cool-season vegetables are frost tolerant.
Winter crops can be planted from seed if there is sufficient time for the plant to become established before the first frost. Otherwise, it’s best to consider using transplants.
It’s important to know the local frost dates and plan and plant accordingly. The approximate frost dates for San Luis Obispo County are:
Never miss a local story.
Interior area: first frost, Oct. 7; last frost, April 20
North County: first frost, Nov. 7; last frost, April 17
Coast/SLO: first frost, Dec. 31; last frost, Feb.15
Select a location that will get full sun, but will be shielded from the wind or frost, such as near a south-facing wall or fence. If the best location for your winter garden is the same location as your spring and summer garden, it’s important to regenerate the soil that provided your spring and summer crops. Work in several inches of compost throughout the planting area to replenish and rebuild the soil.
Choose the right form of weather protection based on your needs and available resources.
Cloches make for a simple cold-weather protectant. A cloche is something you put over an individual plant to protect it from frost or freeze. They can be plastic milk jugs, glass or plastic cloches, or even cardboard boxes.
Row covers are permeable fabrics placed over plants or frames.
Heavier fabrics can protect to 24 degrees.
Cold frames are bottomless frames placed on the ground, with a hinged top that acts like a mini-greenhouse.
Lastly, a good straw mulch of 6 to 10 inches loosely scattered can provide additional protection from frost.
With a little preparation, you can have fresh vegetables throughout the fall and winter seasons.
