Would like to plant Cardinal Dogwood along my rear fenceline. How late in...
Shrubs can be planted until the ground freezes, however it is best if the shrubs have some time to become established before the ground freezes. They will need to be watered until the ground freezes as well. It is highly recommended that protection from rabbits be supplied as well as mulch.
This late in the year it is probably best to wait until spring to plant. There has already been snow in the Dakotas so winter maybe earlier this year than in years past.
A staggered row of shrubs gives the most privacy. Spacing depends on its mature width.
If the line is staggered more shrubs can be planted and it will look filled in sooner.
Large garden centers that have a nursery are good sources so are local small nurseries that can order the shrubs (often with bulk discounts) for you.
