Now that the cold winter months are here, we wanted to allay your concerns regarding the safety of your plants whether newly planted or well established in this, and future, snaps of snow.
The effects of the cold weather can be an issue for any plants (potential cell damage on herbaceous plants and if this was a prolonged soil where the soil froze roots uptake can become inhibited) – especially new plants that have been recently through the shock of being replanted, however the snow can actually be more of a benefit when weather dips down below freezing.
The benefit of snow is that it acts as an insulator, protecting plants from the cold and frost, so this snow should help shield our plants from the cold – also when it melts it will help water the newly plants which is very helpful when establishing plantings!
Because bare root plants lack a rooting media that supplies water to the plant (i.e. soil), they must be stored in a dormant state with temperatures slightly above or below freezing, and high (95%) humidity levels. In other words, these temperatures are ideal for storing the plants before planting so long as they do not freeze, so this may be a benefit…the bigger concern was moisture due the winds.
Generally the biggest concerns we had on planting day was the wind drying out the plant roots and freezing the roots overnight before planting – both of these issues were not a problem since we were able to store the plants in a garage and dip the plants in water before planting and were protected from the high winds by the forest cover.
