I have a lot of the Early Sunglow seed, more than i could plant. I decided to put some in the ground during the heat wave we had in march for the fun of it and all of the seeds germinated fine. However, the past couple of nights have gotten down to 40 degrees, and tonight we have a forecasted low of 37. I have read online that when temperatures drop below 45 the corn seeds become less vigorous and their growth will be hampered. Since all of my seeds germinated well, should I leave them be, or put down some new seed in a couple weeks closer to the normal planting schedule? Thanks for any advice.
