They popped after 3 days and since then it has been cold and rainy. At least 2-3 inches of rain, with more on the way tonight. Temps have ranged down into the mid 50s to mid 60s. The seedlings look ok, but their soil is soaked and since we tend towards "acid rain" in the New England area I'm sure the soil Ph is off. Should I add ground oyster shell to the soil to buffer the rain?
