Best time to plant broadleaf evergreens
We want to plant blue hollies (emerald Magic) and Encore brand azaleas on a northerly facing wall as foundation plants. Our plan was to plant in September. But, we are concerned that fall might not give them enough time to harden for winter. Is spring a much better time to plant these broadleaf evergreens? We also plan to plant Skyrocket Junipers and Dee Runk Boxwoods along the same northern front this September, unless spring is better for them, too. Thank you so much for your kind assistance!

Broadleaf evergreens are best planted in the spring. Some like mountain laurel, boxwood, and hollies can be planted in the early fall if they are given deep watering and a thick acid mulch ( no thicker than several inches and keep away from the stems). Be sure to keep all newly planted trees and shrubs well watered throughout the first year, even in the winter. But do not water when the ground is frozen.
We are not sure what you mean by a Northern front but junipers grow best in full sun.
