Why is my dwarf Alberta spruce turning brown?

Furthermore, why are my spruce trees turning brown?

Spruces can suffer from Rhizosphaera Needle Cast, a fungal disease that causes needles on spruce trees to turn brown and drop, leaving bare branches. It usually starts near the base of the tree and works its way up. You can check for this fungus by looking at the needles with a magnifying glass.

Furthermore, can a brown evergreen come back? Whether needled or broadleafed, both evergreen trees and shrubs can look sickly and brown in spring, especially after a particularly cold or dry winter. Though there may be some branch loss, most brown evergreens do come back as spring progresses.

Also to know, how do you take care of a dwarf Alberta spruce tree?

Dwarf Alberta spruces will grow in full sun to partial shade. Plant it in well-drained, consistently moist soil. If planted in a container, water when the top 3 inches of soil is dry. Once the plant is growing outside, one problem you may run into with this plant is spider mites.

Can dwarf Alberta spruce be trimmed?

Pruning is not necessary with dwarf Alberta spruce since it grows so slowly. Damaged branches should be removed whenever you find them. Pruning to shape them can be done in late winter or early spring when new growth starts to appear. Cut no more than 2 to 3 inches off the tips of the branches.
