Do you think they'll need a mulch over winter, or is your snow cover consistent enough to protect them from cold snaps and heaving?
sooby said:I would not mulch very young seedlings as soon as they are planted for two reasons. The first is that if they are small the mulch will bury the crowns too deep, and secondly there is a possibility of nitrogen depletion right at the interface between a non-decomposed organic mulch and the soil. This would not much affect deeper rooted or established plants but could impact a small seedling that is just planted.
