Days To Maturity
Hi- days to maturity means both things. The convention that is used is as follows:
for vegetables that are typically planted directly as seed in the garden (beans, peas, lettuce, spinach, squash, cucumber, beet, kale, collards) the date means from planting seed
for vegetables that are typically grown from transplants (tomato, pepper, eggplant, cabbage, broccoli, muskmelon, watermelon) the date means from planting transplants
When in doubt check seed catalogs.
