Flowering Dogwood thrives with consistent moisture, particularly when young and during dry periods. Water deeply once or twice a week, allowing the topsoil to dry slightly between waterings but ensuring the root ball remains moist. Avoid overwatering, which can lead to root rot. Mature trees are more resilient but appreciate supplemental watering during extended droughts to maintain health and vibrant foliage.

Prune Flowering Dogwood minimally, primarily to remove dead, damaged, or diseased branches. Structural pruning to improve shape or remove crossing branches should be done in late winter or early spring before new growth begins. Avoid heavy pruning, as it can stress the tree and reduce flowering. Always use clean, sharp tools.

Flowering Dogwood can be propagated from seeds, though germination can be slow and erratic, often requiring stratification. Softwood cuttings taken in early summer can be rooted with hormone. Grafting is also a common method, especially for specific cultivars, ensuring genetic identicality and faster establishment of desired traits.

Repotting is generally not applicable for mature Flowering Dogwood trees as they are planted in the ground. Young saplings grown in containers should be repotted into larger containers as they outgrow their current pot, typically every 1-2 years, until they are ready for permanent planting in the landscape.
