Siberian Dogwood

‘Sibirica’ is a deciduous shrub that is prized for its thicket of red stems that are particularly bright during winter. The foliage turns reddish in fall with small cream-colored flowers in spring followed by bluish berries. It thrives in rich, well-draining soil amended with organic matter, regular water during growth and bloom cycles, and full sun to partial shade. The reddest stems are the youngest ones, so regular pruning is recommended. Where summers are hot, dogwood tends to become stressed and more susceptible to disease such as canker, leaf spot, twig and leaf blights. Insect pests include scale, leaf miner and borers. We cannot tell from the photo if the leaf burning is due to hot weather, dried out soil, or just the natural cycle of going dormant. Suggest you show your photo and a few clippings to a horticulturist at your local garden centre or botanic garden to confirm the problem as well as recommended controls.
