Bush beans are one of those vegetables you can sneak in for a one last time crop! There is an "IF" to my previous statement (sorry)! IF you live in zones 1-4, unfortunately, the growing window is gone. Zones 5-10 have growing windows dependent on each hardiness/growing zone.
You will get beans if you follow "the basics" from a previous blog. (1) Find out your first frost date. (2) Look for varieties that fit into your time frame (For example, here in zone 6 we have 70 days till the first frost date. I am going to look for varieties that have maturity days around 50-55 days).
(3) Add an extra 10 days to the maturity date. In my zone, my best choice is to look for varieties that fall under the 60-65 days to maturity.
I will be able to harvest beans, but they won't be as productive as they were in the summer because of the shorter days (less sunlight) and the cooler temperatures.
As of August 1st, here are the approximate numbers of weeks before the first frost.
Zone 5: approx. 10 weeks (70 days) Zone 6: approx. 10 weeks (70 days)
Zone 7: approx. 11 weeks (77 days) Zone 8: approx. 12 weeks (84 days)
Zone 9: approx. 14 weeks (98 days).
I love to grow heirloom varieties when possible. Bush varieties in the 50–55-day maturity range include: Calima, Cantare, Jade, Roma II, Red Swan, Golden Butterwax, and Contender Beans. (I am a big fan of https://www.rareseeds.com)
