Question: 

How late can I plant snap beans?

Answer: 

Snap beans are a warm-season vegetable and should be planted after the danger of frost is past.  In central Iowa, it’s usually safe to begin planting snap beans in early May.  If harvested frequently, plants should produce well for several weeks.  The last practical date for planting snap beans is August 1.
