The winter window offers a practical opportunity for replanting both coniferous and deciduous trees. Landscape architect and Greenworks ambassador to Russia Ilya Vasetsky shared insights with socialbites.ca about seasonal planting advantages.
Vasetsky notes that during the cold season, plant metabolism slows, and trees become less reactive to sudden changes in their surroundings. This makes them easier to dig up and relocate without stressing their systems as they would be in warmer months.
Among the species highlighted for winter planting are spruce, pine, fir and larch. The expert explains that soil cooled to the point where it remains unfrozen is ideal because trees require less frequent watering and experience minimal moisture loss. Drawing from extensive field experience and accumulated data, he observes that a plant’s natural immunity remains robust through winter transplantation, contributing to stronger resistance against pests and fungal problems after relocation.
Birch, aspen, mountain ash and linden are also suitable candidates for careful winter replanting. These species tend to withstand frost well and adapt to colder conditions when handled properly. Snow cover in winter serves a dual role by nourishing roots in spring and helping to insulate and warm the soil around the root zone as it compacts and settles.
Vasetsky emphasizes cautious planting practices. He recommends ensuring air temperatures are at or above -15 degrees Celsius when placing trees into new sites. The soil used for transplanting should be moist but not compacted, ideally kept around -5 to -10 degrees, so it preps properly for the root system. Proper planning helps ensure the tree receives the moisture it needs without suffering transplant shock.
Effective planting requires a deliberate approach: dig a hole that is roughly twice as wide and deep as the seedling’s root ball, then backfill with soil. Water the area to saturate the soil, scatter snow around the trunk circle to protect the base, and wrap the trunk with burlap down to the first major branches in areas with little snowfall. These steps help shield young trees from cold exposure and improve establishment in the new location, especially when temperatures stay frigid.
In summary, winter planting can be a viable strategy for establishing new trees when executed with care. Proper species selection, soil preparation, and protective measures around the root zone and trunk contribute to healthy establishment and long-term resilience in Canadian and American climates alike.
