So I planted a total of 30 cucumber seeds into a raised bed on 3/29. Right after that we had a few nights that dipped into the mid 40s, and we've not had a nighttime low in April that was above the 50s until last night. Daytime highs have been in the mid 70s to low 80s.

As of today, two weeks after planting, I've had 6 seedlings come up. I've read that cucumber seeds can rot in the ground if the temps aren't right, but this is also my first time direct seeding cukes. At what point should I give up on the first batch and reseed?

Also, if I should reseed, should I do it now and take advantage or wait until our forecasted rain passes, since I haven't heard anything about how MUCH rain it'll be? How much danger is there in over/underwatering before the seeds germinate?
