It is often listed as \u003cstrong\u003eZill O-15\u003c\/strong\u003e. The designation starts with the letter \u003cstrong\u003eO\u003c\/strong\u003e.

Give it room and plan for regular selective pruning. It should not be chosen on the assumption that it is naturally dwarf. Train young branches, maintain access for harvesting, and keep the planting away from overhead lines and structures.\u003c\/p\u003e\n\u003ch3\u003ePlanting and care\u003c\/h3\u003e\n\u003cp\u003eChoose full sun, a warm position, and good drainage. Keep the graft union above the soil and remove rootstock shoots that emerge below it. Water regularly during establishment, then adjust to rainfall and soil moisture. Avoid persistently saturated roots. Feed according to tree size, fertilizer directions, and local guidance.\u003c\/p\u003e\n\u003cp\u003ePrune selectively after harvest to maintain airflow. Florida growers have reported anthracnose spotting and stem-end rot on O-15, so inspect fruit regularly and remove spoiled fruit. Performance varies with growing conditions; this cultivar is not presented as disease-proof or a guaranteed heavy bearer.\u003c\/p\u003e\n\u003cp\u003eProtect young trees from frost and freezing conditions, especially in Central Florida.
