Establishment
6-12 monthsYoung grafted tree with 3-4 feet height, developing branch structure and root system
Stake tree for support, water regularly (2-3 times weekly), apply 2-3 inch mulch layer, protect from wind, fertilize every 4-6 weeks with balanced fertilizer
Vegetative Growth
1-2 yearsTree reaches 6-8 feet, develops dense foliage and lateral branching, no flowers yet
Prune to shape, maintain consistent watering, apply slow-release fertilizer monthly, mulch to retain moisture, monitor for pests
Flowering
2-4 months per seasonTree produces clusters of fragrant, greenish-yellow flowers with velvety petals, typically appearing in spring and summer
Reduce nitrogen fertilizer to encourage flowering, maintain adequate moisture, hand-pollinate flowers with small brush for better fruit set, provide afternoon shade if temperatures exceed 95°F
Fruit Development
3-4 monthsFertilized flowers develop into green, bumpy-skinned fruits that grow rapidly, reaching full size in 3-4 months
Thin fruit to 1 every 6-8 inches on branch for larger fruits, maintain consistent watering (critical stage), provide balanced fertilizer every 4 weeks, watch for pest damage
Harvest
Ongoing throughout seasonFruits mature to yellow-green or green color with softer texture when gently squeezed
Harvest when fruit yields slightly to pressure and skin color lightens; allow to ripen at room temperature for 2-5 days; handle carefully as spiky skin can be sharp

Harvest Tips
Pick fruits when they yield slightly to gentle thumb pressure and skin color changes from dark green to yellowish-green, typically 3-4 days before full ripeness. Harvest by gently twisting and lifting fruit or using pruning shears to cut stem. Fruits will ripen fully at room temperature over 2-5 days. Peak harvest season is typically spring through fall in tropical regions.
Fun Facts
- 🌱 Soursop is native to tropical regions of Central and South America and the Caribbean, and is now widely cultivated throughout tropical Asia and Africa.
- 🌱 The dwarf grafted cultivar was developed specifically to make soursop growing more accessible to home gardeners by dramatically reducing tree height while maintaining full-sized fruit production.
- 🌱 Soursop trees produce flowers with a distinctive musty, tropical fragrance that is quite different from the fruit's sweet aroma, and the flowers bloom repeatedly throughout warm months.
