Is it ok if the temperature dips down to 30 F: seeds out in pots
I sowed some native wildflowers and grasses (native to zone 6 - and colder) into 4" biodegradable small pots (using prepared potting as soil substrate). I didn't get a chance to plant these into the mulch where, being buried so that just the top portion is at ground-level, they would receive some insulation from deep freezing ambient temperatures.
Is it ok that the temperature outside at night (for the next few nights - before I get another chance to plant them) will dip down to 30F? (the substrate is very moist and will be rained/snowed upon). If not, will being placed into an unheated 10' x 10' shed be a big help?
