How to Manage Pests

Pests in Gardens and Landscapes

Time to plant

Green beans, such as snap beans, require moderately warm weather and soil temperatures of 60° F or higher. In cooler soil, seeds rot quickly and growth is retarded. Also, at temperatures below 60° F, plants can be injured or killed by light frosts. Optimum temperatures for germination, growth, and good yields are from 65° to 85° F. Exceptions to this are the lima beans, which prefer even higher temperatures, beginning at 70° F. Fava beans are more tolerant of frosts and can be planted earlier for earlier harvests.

Beans are suitable for a small garden if compact varieties are grown. In a suitable climate, snap beans can be planted more than once a year for a continuous harvest.
