Growing Guide

Planting: In tropical and subtropical Australia, plant grafted mango trees in late spring to early summer (October–December) once soil temperatures are consistently warm and frost risk has passed. Avoid planting during the wet season when waterlogging is likely.

Soil Preparation: Mangoes demand excellent drainage above all else. Prepare planting holes 1 metre wide and 60 cm deep, incorporating coarse sand and aged compost into heavy clay soils. Aim for a slightly acidic to neutral pH of 5.5–7.0. Raised mounds or beds help in poorly draining sites.

Watering: Establish trees with regular deep watering for the first two years. Once established, mangoes are remarkably drought-tolerant — reduce watering during the dry season to encourage flowering. Overwatering during flowering and fruiting causes fruit drop and fungal problems.

Feeding: Apply a balanced fertiliser in spring when growth resumes, then a high-potassium feed during fruit development. Avoid high nitrogen feeds once flowering begins as this promotes leafy growth at the expense of fruit.

Multiplication: Mulch generously around the drip line, keeping mulch away from the trunk to prevent collar rot.

Harvest Tips: Mangoes typically take 100–150 days from flowering to harvest, usually between November and March. Pick fruit when the shoulders round out and a fruity aroma develops at the stem end. Allow fruit to ripen off the tree at room temperature for best flavour.

🤝 Good Companions

Plant mangoes alongside lemongrass which repels insects and benefits from the mango's dappled shade and interplant with basil or marigolds to deter thrips and fruit flies naturally. Comfrey planted beneath the canopy acts as a dynamic accumulator drawing up deep nutrients and providing excellent organic mulch material when cut back regularly.

❌ Avoid Planting With

Avoid planting mangoes near other large fruiting trees such as avocados or citrus as root competition and overlapping pest and disease pressures — particularly fungal pathogens — can compromise the health of all trees involved. Keep mangoes well away from vegetable gardens as their allelopathic leaf litter can inhibit the germination and growth of smaller crops.

🐛 Pests & Diseases

In Australia, mango trees face significant pressure from Queensland fruit fly (Bactrocera tryoni), which can devastate crops — manage with protein-based baits, exclusion netting, and Eco-naturalure organic lure traps. Anthracnose fungal disease (Colletotrichum gloeosporioides) causes black spotting on leaves, flowers, and fruit, particularly during humid wet seasons; control by improving airflow through pruning and applying copper-based fungicide sprays preventatively during flowering. Mango seed weevil and mealybugs are also common concerns, addressed organically through sticky trunk bands and horticultural oil sprays applied during dormancy.

🌱 Fertilising

Feed young mango trees every six weeks during the growing season (spring through summer) with a complete slow-release fertiliser formulated for tropical fruit trees, transitioning to a low-nitrogen, high-potassium blend such as a specialist mango or citrus fertiliser once the tree reaches bearing age. In Australian tropical conditions, supplement with trace elements including zinc, boron, and manganese annually, as sandy coastal soils are frequently deficient in these micronutrients essential for quality fruit production.

✂️ Pruning & Training

Prune mangoes after harvest (typically between April and June) to maintain an open vase shape that allows light penetration and airflow, removing crossing branches, deadwood, and any branches growing below 60 cm from the ground. Tip-prune young trees during the first two to three years to encourage a strong, low branching framework and to keep the canopy at a manageable height — ideally under 4 metres — for practical harvesting in home garden settings.

🔬 Propagation

Mangoes are best propagated through grafting, specifically whip-and-tongue or cleft grafting onto established seedling rootstocks, which guarantees true-to-type fruit production and significantly reduces the time to first harvest compared to seed-grown trees. Grafted trees from reputable Australian nurseries typically fruit within three to five years, while seed-grown trees — which involve simply planting the large polyembryonic seed — may take eight or more years and produce inconsistent fruit quality.
