These evergreen conifers are known for their upright pyramidal growth. Some varieties are even grown by Christmas tree farms specifically for their shape.
Heights vary between varieties, with most averaging between 30-60 feet tall at maturity. Dwarf varieties do exist, allowing those of us with smaller yards to enjoy these trees too.
Full sun, at least 6 hours per day.
Moist, well-draining soil. Spruces generally prefer a pH between 6.0-7.5 but they are highly tolerant of more acidic or more alkaline soils. These trees can handle most soil types, but they tend to do better in looser soils. Amend compacted or clay soils with Lobster Compost.
Prune in late winter/early spring when the tree is dormant.
Fertilize in spring and fall with a tree and shrub fertilizer like Fertilome Tree & Shrub.
