Amonogawa trees are a type of Japanese ornamental cherry tree. They grow a plethora of short-lived and fragrant pink blossoms during the spring each year. Their deciduous leaves turn orange and red and then fall off during the fall each year. People often use amonogawa cherry trees in rows, because they grow up to 10 meters tall, but often stay only a few meters wide. The trees require some care to keep them healthy, but grow relatively easily.
Prune off any dead or damaged branches when they show up. Gardeners should also prune off branches that damage each other by rubbing against each other.
Prune long and heavy outer branches during mid or late summer: the weight of winter snow can pull the branches down during the winter. This weight does not usually damage the trees, but it changes their shape and makes trees in rows bump into each other. Do not prune after August, because, according to the National Gardening Association, fall pruning makes trees susceptible to winter injuries.
Prune other nearby trees that block the cherry trees sun, because Japanese cherry trees grow best with lots of sunlight.
Maintain a layer of mulch around the base of the tree. The mulch helps prevent weeds, which look unsightly and compete with the trees for soil moisture and nutrients. It also helps the soil retain water.
Fertilise the tree each spring, as the National Gardening Association suggests for cherry trees not bearing fruit. Use a balanced fertiliser, and apply the recommended amount on its instructions.
