25 Garden crops to plant in August for your fall garden

If you want to extend your back yard bounty of fresh veggies, now is the time to start your fall garden.

There are many garden crops that can handle some frost and some that can tolerate temperatures well below freezing. Root veggies such as carrots, beets, kohlrabi and turnips actually taste better after some frost, as do leafy greens like kale.

You can find the average first frost date for your area here. Then just check the days needed for each seed variety and count backwards from that date to see when you should plant.

To be extra cautious, you may want to play a week or two earlier.

Here in my part of southwest Minnesota, our average first frost date is September 28. That gives us an average of 58 days to harvest if we start on August first. Of course, plants that can handle some frost or colder temperatures can be harvested well after that.

Here are some good picks for your fall garden, along with the average days to maturity and how cold tolerant they are:

1. Arugula – 30-40 (frost tolerant — can handle temperatures to the high 20s)
2. Mustard greens – 30-40 (frost tolerant — can handle temperatures to the high 20s)
3. Basil — 30-60 (killed by frost)
4. Radishes – 30-60 (can dig until ground freezes)
5. Spinach – 35-45 (frost tolerant — can handle temperatures to the high 20s)
