Soil hardens more quickly in a container than in the ground. Even though this winter has been mild, younger plants whose roots haven’t settled may not do so well outdoors.
Prune your plants once they have gone dormant and store your plants according to their winter hardiness. Consider covering them – anything from evergreen boughs to blankets, straw to shredded bark can be used to safeguard pots and their contents. If they can’t stand freezing temperatures, place them in an unheated garage above freezing. For more container plant ideas, go here.
