As with spring cool season and summer vegetables, timing is very important. We can take advantage of warm soil temperatures in August knowing that cooler days and cooler nights will begin in September and will continue through October. In this way, we have good plant development, increased flavor, and sweetness in our fall vegetables. 

Below is a guide of which fall vegetables will perform well, and the appropriate timing for planting and days to maturity – both seeds and started plants. 

Starting From Seeds – Vegetables for Fall 

Warm soils of mid-August to mid-September equal quick germination and allow time for plants to mature during the Fall season.

Started Plants – Vegetables for Fall 

We often experience greater success when planting certain started vegetables. Fall vegetables from started plants mean fewer days to maturity as opposed to seeds, which are easier to achieve overall success.
