Fertilize: Use Master Nursery® Fruit Tree & Vine Food twice a year, around Memorial Day and Labor Day. If you prefer organic fertilizers, use Gardner & Bloome® Citrus & Fruit Tree Fertilizer two to three weeks earlier. Water in fertilizer immediately after application. Supplement organic fertilizers with iron sulfate to prevent chlorosis.
Water: At planting, construct a soil berm at the drip line of the tree. As the tree matures, extend the basin to the span of the drip line. Flood weekly during the first year and then at two to four week intervals when the tree is mature. If a drip system is used, place hosing along the tree’s drip line with emitters on 18 inch centers. This system will also need to be adjusted as the drip line expands. Both of these methods are preferable to sprinklers, since they reduce water splash, a common byway of fungal spores. If sprinklers must be used, adjust heads so that they angle water low and away from the trunk.
Other comments: Watch for oozing of amber-colored gum on twigs, branches or trunk, which may indicate the presence of borers or fungus. Bring several leaf and twig samples to Wegman’s Nursery for evaluation whenever these or other symptoms appear.
Paint trunks and lower branches of young or non-vigorous trees with a one to one mixture of white interior latex paint and water to prevent sunburn injury and reduce borer infestations. Apply the paint mixture from two inches below the soil surface to the first scaffold branches.
