Sweet cherry trees are a commonly grown fruit tree in many home gardens and are low-maintenance when it comes to fertilizing. Giving it what it needs most, nitrogen, at the appropriate time will allow you to enjoy the fruits of your labor and from the cherry tree.
Choose the correct type of fertilizer. Use a nitrogen or complete fertilizer such as 12-16-12. Look for approved sources of organic nutrients if you prefer to organically fertilize your cherry tree.
Apply the fertilizer at the correct times. Fertilize a cherry tree at the second week and sixth week after planting, and fertilize it annually in the fall following the planting. Supplement additional nutrients, if needed, during the summer with a foliar spray. Use the correct amount of fertilizer. Apply 1 ounce of fertilizer per square yard.
Use a garden spade to dig some dirt from around the tree. Spread a thin layer of fertilizer in its place, and mix the fertilizer into the soil with the spade. Water the fertilizer to activate it.
Place mulch around the base of the tree. Prevent fungus from growing on the cherry tree by keeping a 6-inch space between the mulch and trunk.
