Watering Adequate and regular watering is critical for fruit formation and development. Lack of water can lead to loss of flowers or fruit. Deep water at least weekly especially when plants are in new growth, flowering or fruiting. Water more frequently if plants are in hot, dry or exposed conditions or if they are growing in containers. If soil or potting mix starts to repel water (pools on top or runs off the soil) then it may need a soil water such as Seasol Super Soil Wetter and Conditioner to allow the water to penetrate through the soil down to the plant’s roots.
Feeding and mulching Feed every season through the growing season (spring to autumn) with a complete fertiliser for fruiting plants such as Seasol plus Nutrients Fruit & Citrus. Additional apply a liquid fertiliser such as PowerFeed PRO SERIES Flowers, Fruit & Citrus every 2 to 4 weeks especially during flowering and fruiting. Protect the soil with a 5-7cm layer of coarse organic mulch enriched with well-rotted manure, which helps keep the soil evenly moist and weed free. Keep nearby grass well mown.
Pruning Mangoes need little pruning other than ensuring and open shape to assist fruit ripening.
Watch out Birds, bats and other animals such as rats and possums can attack fruit. Insect pests include scales, which are controlled with EarthCare Enviro Pest Oil insect spray and fruit fly, which can be prevented from attacking the crop by bagging fruit and by using organic fruit fly lures.
Poorly drained conditions can lead to root rot diseases including phytophthora so always plant these trees in well-drained soils.
Diseases that affect particularly mango fruit include anthracnose and black spot. These diseases affect fruit quality and can lead to fruit drop. Apply an organic fungicide at flowering and as fruit develops.
