Why is Autumn the best time of year to plant trees and shrubs?
Trees, like animals, hibernate. Before they do so, they need to obtain as much nutrients as possible to survive the winter. That’s why the end of the growing season is the best time to plant trees and shrubs, once in the ground there’s a final root spurt in a bid to gain nutrients before hibernation. Even during winter while the tree is dormant, roots may grow, albeit at a slower pace and only if the ground temperature is above 5 degrees Celsius.
Is there a difference between when I should plant a deciduous tree and an evergreen tree?
A deciduous tree, that is a tree which sheds its leaves during Winter can be planted successfully throughout winter up until it comes out of dormancy in March/April.
Evergreen trees on the other hand can decline when planted in deep winter. We suggest you plant evergreen trees between September and October or between March and May.
Why is it not always the best time to plant a tree in Autumn?
Contrary to our comments above sometimes Autumn is not the best time to plant deciduous or evergreen trees. Coastal areas or places that are heavily exposed can cause the tree to decline due to bad weather conditions. So consider planting in spring, just before the new season leaves begin to emerge.
