Care Guide
Growing pawpaw trees requires some specific care to ensure that they produce healthy fruit. Here are some tips for caring for your pawpaw tree:
Water: Pawpaw trees require consistent moisture, especially during the growing season. Water deeply and frequently, especially during drought conditions.
Fertilization: Apply a balanced fertilizer in the spring before the tree begins to grow. Use a slow-release fertilizer that is high in nitrogen, phosphorus, and potassium.
Soil: Pawpaw trees prefer well-draining soil that is rich in organic matter. They do best in a slightly acidic soil with a pH between 5.5 and 7.0.
Sunlight: Pawpaw trees prefer partial shade and do not tolerate full sun exposure. Plant them in a location that receives morning sun and afternoon shade.
Hardiness Zones: Pawpaw trees are hardy in USDA zones 5-9.
Common Pests & Diseases

Black Spot: This fungal disease causes black spots to form on the leaves of the tree. It can be controlled with a fungicide spray.
Spider Mites: These tiny pests can cause damage to the leaves of the tree. They can be controlled with insecticidal soap or neem oil spray.
Deer: Deer are known to eat the leaves and bark of pawpaw trees. Protect your tree with a fence or repellent spray.
