What are the optimum conditions for germinating broccoli seeds? What temperatures are best and are there any special seed treatments? |
No seed treatments are necessary for broccoli. Sow seeds indoors 6 weeks before setting out, or direct sow in the garden in early spring. Sow seeds 1/2" deep in moistened seed starting mix, or outdoors in prepared bed. Optimum soil temperatures range from 45F-85F with 5-17 days to emergence. |
