Trees will bloom and fruit will ripen soonest in hot areas. Mulch with partially decomposed compost after soil has warmed or you've taken the tree outdoors, to prevent weeds, keep soil evenly moist, and provide disease protection. In hot climates, trees in pots may need to be watered daily. Conversely, inadequate watering during bloom or the growing season will result in blossom or fruit drop. Check for Insects often.
Most trees have few problems with insects or diseases.
Ultrafine horticultural oil spray will take care of most insects you do find. Spraying before you bring the tree indoors in the fall will help keep problems to a minimum during the winter. They can be stored on the tree for up to three weeks and picked as needed. They can also be stored in the refrigerator for up to three weeks. Trees in hot climates will normally flower and have ripening fruit year round.
