Fuyu persimmons are one of 800 cultivars of the Diospyros kaki or Japanese persimmon species and are formally known as Fuyugaki. They are slightly elongated with four gently sloping sides, a rich coral orange outer skin and dark orange-hued flesh. They are roughly 2 inches in length, 2 3/4 inches in width and virtually seedless. You should fertilize persimmon trees in the spring to feed the roots during the trees' most active growth period.
Select a complete 4-8-3 granular fertilizer, calculating the appropriate dose by using 1 lb. of fertilizer for each year of the Fuyu tree's age.
Scatter the fertilizer evenly around the base of the tree in a wide doughnut formation at least a foot out from the trunk and extending at least a foot past the drip line of the tree.
Mix the fertilizer grains gently into the top 2 inches of soil with a rake or cultivating fork to nestle it into the soil.
Water the fertilizer and surrounding soil deeply until the soil is drenched to a depth of at least 12 inches. This will kick start the spread of nutrients down into the root zone of the tree.
