Is it ok if the temperature dips down to 30 F: seeds out in pots

njbiologyMarch 5, 2013

Hi,

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?

Thank you,
Steve

Given the types of seeds you list - hardy varieties - then it would not have any effect on them.

You might check out the Winter Sowing forum here for some of their techniques (very similar to what you describe doing) that can insure more success.
