Year-round

General pawpaw (Asimina triloba) care for the Binghamton, NY area: right site, steady moisture, and a few simple handling cautions.

• Give pawpaw part sun to light shade with deep, rich, well drained soil that still holds some moisture. It tolerates occasional wet spots but not standing water.
• Water new trees regularly through the first two growing seasons. Established pawpaws need less help but still want even moisture rather than drought, especially on sandy or gravelly sites.
• Plant two different pawpaw trees or cultivars near each other for more reliable fruit set. A single tree can still grow well, it just may not fruit as heavily.
• Expect root suckers to pop up around the base. Cut or mow them off at ground level if you want a single clean trunk form, this is routine and not a sign of a problem.
• Fruit skin, seeds, leaves and bark contain compounds (acetogenins, including annonacin) that can cause stomach upset if eaten and skin irritation on contact. Wear gloves when handling fruit or pruning, and keep unripe fruit and seeds away from kids and pets.

A single-trunk pawpaw with suckers kept cut back reads as an ordinary small tree, which keeps a front-yard planting HOA-friendly.

Fall

Fall brings harvest, leaf drop, and the first frosts of the season (commonly October in the Binghamton area), which established pawpaw handles well.

• Harvest ripe fruit as it softens and drops, usually from September into early October here, before hard freezes set in.
• Clean up dropped fruit if you want to discourage wasps, raccoons, or other wildlife from lingering near the tree.
• Leaves turn yellow and drop after the first frosts, this is normal seasonal dieback, not a health problem.
• Fall is a good window to plant balled-and-burlapped stock so roots can settle before winter, water it in well before the ground freezes.

Cleaning up dropped fruit keeps the planting tidy and HOA-friendly along a front walk or curb strip.

Winter

Winters in USDA zone 6a around Binghamton bring hard freezes. Established pawpaw is fully dormant and hardy, young trees need a little more protection.

• Established pawpaw is hardy through zone 6a winters with no special protection needed once the tree has a few years of growth.
• Wrap or shield young trunks in their first winter or two if the site is exposed and windy, winter sun and wind can scald thin young bark.
• This is a good window for structural pruning while the tree is dormant and bare, since you can see the branch framework clearly.
• Leave leaf litter and mulch in place over winter, it protects roots through freeze and thaw and breaks down into the soil by spring.

Spring

Spring around Binghamton (USDA zone 6a, last frost typically mid to late May) is for planting, feeding, and watching young trees through late cold snaps.

• Plant balled-and-burlapped or potted pawpaws after the last hard frost, generally mid to late May in this area, once soil has warmed.
• Give new plantings a deep, weekly soaking through spring rather than light frequent sprinkles, this builds the deep root system pawpaw needs.
• A late frost after leaf-out can brown new growth on young trees. This is usually cosmetic, the tree typically pushes new leaves back out within a few weeks.
• Feed established trees in early spring with a balanced fertilizer if growth looks thin, pawpaw is a fairly heavy feeder once established.

Summer

Summer is the main growing and fruit-development season for pawpaw. Steady moisture and a light hand with pests matter most.

• Keep soil evenly moist through summer heat, pawpaw does not tolerate prolonged drought well and can drop fruit if it dries out.
• Mulch 2 to 3 inches around the base to hold moisture and reduce root competition, keep mulch off the trunk itself.
• Watch for the pawpaw peduncle borer, which can damage flower stalks and reduce fruit set. Damage is usually minor and does not need spraying in a home garden.
• Fruit generally ripens from late summer into early fall in this region, it softens and often drops when ready rather than needing to be pulled.
