Regular watering is essential, especially during dry periods. The tree is relatively easy to care for but does require some attention to its light and moisture needs.Soil
The Giant Dogwood prefers well-draining loamy soil that retains moisture without becoming waterlogged. A mix of garden soil with organic matter such as compost is ideal. Ensure the soil pH is slightly acidic to neutral for optimal growth.Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10 during the growing season. Fertilize once a month to provide the necessary nutrients for healthy growth. Avoid over-fertilizing as it can harm the plant.Repotting
Repotting is generally not required for outdoor trees, but if grown in a container, repot every 2-3 years. Choose a larger pot with good drainage and fresh soil mix. Repot in early spring before new growth begins.Propagation
Propagate Cornus controversa through softwood cuttings taken in late spring or early summer. Dip the cuttings in rooting hormone and plant them in a well-draining soil mix. Keep the cuttings in a humid environment until roots develop.Pruning
Prune the tree in late winter or early spring to maintain its shape and remove any dead or diseased branches. Light pruning can also be done after flowering to encourage new growth and improve air circulation.Toxicity
Cornus controversa is not known to be toxic to pets or humans. However, it is always advisable to keep pets and children from ingesting any plant material.Additional
