What Kousa Dogwood is
Kousa Dogwood grows as a perennial and reaches around 25 feet at maturity. It blooms in spring. It's also deer-resistant and well suited to containers.

Plant it right
Set kousa dogwood in part sun with evenly moist to well-drained soil. Many fruit trees need a second variety nearby to pollinate — check before you plant just one.
Match the soil
Kousa Dogwood prefers pH 3.9 to 7.7 (USDA PLANTS Database). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.
Water steadily
Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.
Be patient, then harvest
Prune annually while the tree establishes; fruit trees reward patience with years of harvest. Local Extension guides publish per-cultivar bearing-age tables.
