Fertilizing the soil around your cherry tree with high-nitrogen fertilizer during the first years of seedling growth is especially important to encourage growth and speed fruit production. As with other fruit trees, you must also mulch after fertilizing and water the soil whenever it is dry.
Determine what type of cherry tree you're growing and what type of soil is needed for your specific tree. Varieties can include ornamental flowering cherry trees or varieties that bear fruit.
Test your soil so you know what nutrients are required for your tree. Purchase a pH testing kit from your local garden store and follow the directions. Some garden centers will test your soil for you.
Apply a fertilizer that is high in nutrients during the early spring. Apply 1 lb. of 10-10-10 ratio fertilizer for each square foot surrounding your cherry trees. Spread the fertilizer at least ½ inch thick around the base of your tree.
Continue applying the fertilizer to your cherry tree every spring until it fruits or flowers. It typically takes between two and four years for cherry trees to bear fruit.
Apply half of the amount of fertilizer the year your tree bears fruit. Apply the fertilizer only until the fruit appears. Fertilizer after that can hinder the production of fruit and only aid leaf growth.
