Seedling/Young Sapling
6-12 monthsSmall plant with tender green leaves, minimal branching. Grafted trees start with established rootstock.
Protect from strong winds and direct intense sun. Keep soil consistently moist but not waterlogged. Stake for support if necessary. Remove competing leaders to establish single main trunk.
Establishment
1-2 yearsGrowing trunk with lateral branches developing, plant reaches 3-6 feet tall. Leaves are larger and more abundant.
Begin light pruning to shape canopy and encourage branching. Maintain consistent watering schedule. Apply balanced fertilizer every 2-3 months. Mulch heavily around base.
Juvenile Growth
2-3 yearsTall sapling becoming tree-like, 8-15 feet; dense foliage. May produce flowers but fruit typically removed.
Continue structural pruning. Increase nitrogen-rich fertilizer to promote vegetative growth. Continue consistent watering. Remove any flowers to redirect energy to growth.
Pre-Flowering/Flowering
3-6 weeks (flowers)Mature tree 20-40 feet tall with full canopy. Clusters of yellowish-white flowers appear, typically once or twice yearly depending on climate and conditions.
Reduce nitrogen fertilizer; increase phosphorus and potassium to encourage flowering. Maintain consistent moisture but slightly drier period may trigger flowering. Thin flowers if overcrowded.
Fruiting and Harvest
3-4 months from fruit set to harvestLarge spiky fruits develop from flowers, reaching 4-12 pounds. Fruits mature and change from green to yellowish-brown over 3-4 months.
Ensure consistent water supply during fruit development. Thin fruits for larger individual sizes if desired. Protect from pests. Harvest fruits when they naturally drop or yield slightly to pressure.

Harvest Tips
Monthong fruits typically mature 3-4 months after flowering. Harvest when fruits naturally fall to the ground or when they emit the characteristic durian aroma. Ripe fruits yield slightly to gentle pressure near the base. Fruits can also be harvested slightly underripe and ripened indoors in newspaper for 1-3 days. Wear gloves as spikes are sharp. In commercial settings, fruits are harvested by hand-picking or allowed to drop naturally. Best harvested in morning before extreme heat.
