Because 15 trees were selected instead of one, there will sometimes be variation between trees grown under the name Milky Way. The Chinese dogwood is easier to grow than our native dogwood, but it still does best when given a reasonably fertile soil and good drainage. While I have seen it used in the middle of parking lot islands in full sun, it is better sited where it gets some afternoon shade. It should be watered during dry periods, but otherwise requires no special care. It is not as susceptible to the dogwood borer and, so far at least, has shown good resistance to both dogwood powdery mildew and dogwood anthracnose that have plagued our native trees.
Chinese dogwoods can sometimes be slow to flower.
If grown from seed, it is not unusual for trees to take seven to 10 years to reach maturity and become old enough to bloom. Even budded trees, which in theory at least should always bloom, are shy to bloom their first few years. The best way to set good flowering is to avoid overfertilizing while keeping the plant well watered during the early part of the growing season. Then, after mid July cut back on watering and allow the plant to experience the joys of an Arkansas summer. This more stressful summer experience usually promotes good flower bud set in the fall.
