temperature required to plant beans
Soil temperatures at which vegetable seed will grow include the minimum temperature required for seed growth, an optimum temperature and a realistic soil temperature. The realistic soil temperature is somewhere between optimum and minimum; it is the temperature at which you should plant to insure maximum success.For instance, the optimum soil temperature for seed germination of vegetable crops, such as cucumber, cantaloupe, okra, pumpkin, squash and watermelon, is 95Â°F.he realistic soil temperatures recommended for these crops are beans (72Â°F), beets (45Â°F), tomato (55Â°F), turnip (50Â°F) and corn (55Â°F). As might be expected, vegetables which are really cold-tolerant, such as carrots, parsley, lettuce and spinach, have lower optimum soil temperatures for seed germination.
