We are excited to see this rising interest in pawpaws and hope this guide will encourage more thinking about this hardy fruit. Multiple fruits grow from a single flower.Ĭulinary innovators in New York have begun selling pawpaw beer, pawpaw liqueur, and a host of seasonal fresh-fruit offerings. These will become flowers, while slim, pointy buds will become leaves.
In fall, look for round buds on young twigs. Pawpaws will take between 5 to 8 years to set fruit after planting. Pawpaws need to exchange pollen to bear fruit, but each tree will make male and female flowers-so plant several trees or exchange a flowering branch with a neighbor and use a paintbrush to hand-pollinate. Pawpaw flowers are large, crimson-colored and pungent-smelling, attracting mayflies and other detritivores for pollination. Look for smooth-skinned caterpillars with a prominent hunchback. Pawpaw bark, seeds, and leaves contain insecticidal compounds that few bugs enjoy eating, with one notable exception: caterpillars of the zebra swallowtail butterfly are happy to munch on pawpaw foliage.
PAW PAW TREE FLOWERING HOW TO
It provides information about how to store pawpaw fruit for commercial sale, and the genetic background of pawpaw varieties grown in the Finger Lakes pawpaw orchard.Īs an edible and ornamental tree, pawpaws can create a tropical feel in any landscape, with their drooping leaves that can grow up to one foot long-these turn lemon-yellow in the autumn. This guide was written in consultation with nurseries that grow pawpaws, pawpaw growers, and agricultural researchers at Cornell University. The Cornell pawpaw planting is the only commercial-scale pawpaw grove in New York, with approximately 100 trees lined up in 5 rows. But hard pawpaws picked too early will not fully ripen off the tree.Are you a fan of pawpaws? These custardy fruits can be hard to come across, so this guide provides information on how to grow your own pawpaw from seed, and how to care for grafted seedlings. To outsmart birds and other wildlife that may try to swipe perfectly ripe fruit, you can pick them a little before they are completely ready, and the last bit will ripen soon afterward. Harvest the fruits in late summer when they are soft to the touch and detach easily.
Sunflower is a rare self-fertile variety that theoretically should bear fruit if planted solo but would be more reliable if paired with a mate.Īvoid buying balled-and-burlapped trees, which are grown in fields and then dug up for sale the practice risks damage to pawpaws' long taproots, impacting their ability to take up water effectively. Seek out grafted, named cultivars, such as Davis, Mary Foos Johnson, Overleese, Sweet Alice and Taylor, which will bear fruit in a couple of years, as opposed to seed-grown trees, which can take as long as six to 10 years to produce. In most cases, you’ll need to grow two different pawpaw cultivars to ensure cross-pollination and fruit production. Pawpaws are not invasive but will form a thicket if left unchecked. As far as care, the only other thing you’ll want to do is remove suckers that grow around the base of the tree. Water young trees regularly for a year or two until they’re established, and apply a 20-20-20 fertilizer once a month in April, May and June only. Select a sunny to partly sunny spot that offers some wind protection, and plant it in well-draining, slightly acidic soil with a pH level between 5.5 and 5.7. The pawpaw is about as low-maintenance as a fruit tree could be.
