Soursop Plant :
Soursop trees have shallow root systems and prefer rich organic soil. The trees should be provided with a thick layer of mulch to protect the roots during extremely warm dry weather conditions. Trees exposed to dry conditions for prolonged periods will shed all leaves. Should your tree shed all its leaves be sure to water but not heavily until plenty of new leaves appear.
Soursop Plantation Procedure
- Select a planting location for the soursop tree on the south side of a house. The area should have well-draining soil and at least six hours of direct sun exposure per day.
- Dig a hole with a shovel that is twice as wide but no deeper than the root ball of the soursop tree. Remove the tree from the nursery container, separating the exposed roots from the root ball by hand. Set the tree upright in the center of the hole and backfill with the native soil until it is even with the top of the root ball. Do not tamp the soil while backfilling.
- Water around the base of the soursop tree with a watering hose set on a slow trickle at transplant time, and water to a depth of 12 inches. Supplement water for up to three years after planting to a depth of 12 inches. Water at least twice a week during the growing season in the morning. Additional watering may be needed during periods of drought. 4. Spread an even 4- to 6-inch layer of organic mulch around the base of the soursop tree by hand, starting 3 inches from the trunk and stopping at the outer edge of the canopy’s drip line. Reapply as necessary.
- Apply 10-10-10 granular fertilizer, sprinkling it by hand around the base of the soursop tree in springtime at a rate of 1/2 pound per tree the first year after planting. Apply the same granular fertilizer, sprinkling it by hand around the base of the soursop tree, at a rate of 1 pound per tree the second spring after planting and at a rate of 3 pounds per tree the third spring and thereafter. Follow all manufacturer’s labeling instructions on the fertilizer container. 6. Remove dead, weak or diseased branches from the soursop tree with pruning shears in the spring before the leaf buds begin to open. Make the cut at a 45-degree angle, 1/4 inch above an outward-facing bud. If the entire branch needs to be removed, make the cut flush with the trunk of the tree. Soursop trees have shallow root systems and prefer rich organic soil.
