Here is the equipment and enviroment you will need to grow soursop:

- Peat pots filled with potting soil
- A large pot

Notes about growing soursop trees:
A soursop tree can grow from 25 to 30 feet tall.
The tree produces an oval-shaped spiny fruit with a tender yellow/green skin.
Typically, it is grown in countries like Mexico, Jamaica, the West Indies, northern South America, China, Australia Southeast Asia and Africa. In the U.S., it can grow in central to southern Florida, southern California, southern Arizona and southern Texas.
The tree that produces soursop fruit needs a tropical climate. It will not survive a frost. It will suffer damage at 30 F (around -1 C) and it will die at 26 F (-3 C).
U.S. Plant Hardiness Zones
The U.S. Department of Agriculture plant hardiness zones 10 and 11. in rich. In Florida that is the zones south or Orlando and Tampa. In California it is the coast regions from San Luis Obispo south and Bakersfield. Southern Texas and southern Arizona also match this criteria. See more here
Plant a Graviola tree in rich well-drained soil with 5 to 6.5 pH.
How to plant soursop seeds to grow a tree
Soursop seeds are about 3/4 inch and are brown
Indoor graviola tree planting
- Wash soursop seeds and prepare a warm, shady indoor spot for germination.
- Plant the seeds in peat pots filled with potting soil, less than 30 days after harvesting from fruit.
- Keep the soil moist to the touch. Soursop seeds will germinate in 15 to 30 days if the are viable.
Outdoor graviola sapling planting
If you live in a suitable climate as noted above (no frost, warm tropical or sub-tropical temperatures) you can transplant seedlings outdoors, or accommodate the growth of a tall indoor potted tree in a greenhouse.
- Prepare a sunny, south-facing spot with wind protection in the garden and rake 2 inches of compost into the soil.
- Transplant 12-inch-high seedlings into the yard in the spring, spacing them at least 12 feet apart. Dig holes big enough to hold the root ball of each plant. Cover the base of the plant with soil
- Add 3 inches of mulch to keep moist.
- Water soursop plants often enough to keep the soil moist, but not wet, during hot weather.
- When the weather cools in the winter, be sure to reduce watering. Soursop plants can tolerate drought. That said they can develop pest problems if they are always wet.
- Provide soursop plants with 10-10-10 fertilizer, using a total of one-half pound of fertilizer per tree in the first year. Split the amount quarterly. In the 2nd year, raise the amount to 1 pound. Thereafter use 3 pounds of fertilizer per year.
- Reapply mulch annually to the trees.
- Widening the mulch application area to 5 feet as the tree’s root system expands.
