Kousa Dogwood Care
Kousa Dogwoods like full sun to part shade and soil that is well-drained, acidic, and nutrient rich.
Once established, dogwood trees are drought tolerant. In extended dry and hot periods this tree will benefit from a weekly deep watering.
Fertilize your dogwood tree in early spring for best performance. Choose a balanced slow release fertilizer.
Mulch your dogwood tree with 1 to 2 inches of mulch extended at least a few inches past the root zone. Mulch helps the ground retain moisture, keeps competing weeds at bay and protects the dogwood’s shallow roots. Do not pile up mulch against the trunk. This can cause moisture to get trapped and invite pests and diseases to damage your tree
Dogwoods don't generally require pruning, but if needed, prune in late fall or early winter when the tree is dormant.
