Planting dates, depths, spacing and germination time

The planting dates are approximate and generally based on the warming and temperature of the soil. Because there are 'new and improved' hybrids of many of these plants developed each year, more detailed information should be taken from the seed packets as to actual timing and planting specifications in your area.
