There are many varieties of beans you need to test several to find the ones you like best. Many years ago in TN I experimented by planting several rows of different beans about 6 varieties each time. I learned we like Blue Lake Bush Beans best they have NO strings, grow larger than most beans and still are NOT tough and they have a very good flavor. I still plant Blue Lake Bush Beans.
I plant 3 rows of beans about 25 foot long each 32" apart. Beans are ready to harvest in about 65 days. 65% of my bean crop comes from the first harvest, 25% from second harvest and 10% from third harvest so I pull all my bean plants up after the first harvest and plant a new crop of beans this gives me 30% more beans for the whole summer, much better than 1 crop of beans. This also gives me 65 pints of beans in Mason jars and we eat all the beans we can eat all summer along.
Bush beans make more beans than pole beans. Pole beans are easy on your back when picking but you have to, cut poles, put up poles, take down poles, clean poles, every year. I use a small chair, large hat, and 5 gallon bucket to pick my bush beans and I crawl around on my hands and knees in the dirt to pick beans.
When I lived in Phoenix Arizona area I planted beans in November and March. I had a homemade irrigation system. I watered my beans 15 minutes every day at sun down. The beans I planted in March did better than November beans probably because days were longer and it was much warmer weather and not very hot on harvest day.
I like to plant beans in between the tomato rows. 1,2,1,2,1,2,1 with 1 being tomatoes and 2 being beans. After the bean harvest I pull up the bean plants it makes more room for the tomato plants this makes it easy to harvest tomatoes too. I plant beans is a WIDE row sow the seeds like grass seeds 2" apart in 6" wide rows. This puts a lot of plants in a small space and gives me a larger harvest for a small space.
