I've heard all the reasons why guys don't plant on a timely basis; "it's too dry still", "the ground is too wet to work", "if I plant it now, it will get too stemmy by deer season", "it's too late now, I won't get any bulb production". I heard a new one, today...I spend too much money on this stuff for the conditions to not be "perfect". Well, God and Nature have a different plan, and neither have any respect for yours. That's just how it is, so I plant by a schedule that aligns with the attributes of the plant and the typical conditions one will see in their area. The biggest problem with waiting is this: As sure as you put off planting until a high-percentage rain event is on the way, something will come up to keep you from getting the seed in the ground at that time.
Know the science behind what you're doing and plant in a timely manner, but then trust in a higher power to take it from there.
