When to buy trees and shrubs
Autumn is a great time to buy and plant a new tree or shrub, as you can choose from container-grown and bare-root plants.
However if pushed for time, you can plant at any time until early spring as long as the soil is dry enough to work (if it sticks to your boots or tools it is too wet).
Container-grown trees and shrubs can be planted at more or less any time of year, but need thorough, regular watering after planting to ensure good establishment. If planted in spring or summer it can be very challenging to keep them alive during hot, dry spells.
