The pawpaw tree’s unique flowers are a nice addition to the landscape.
How to Grow Pawpaws
Consume with Caution
Also known as “ Indiana banana , ” “ Quaker pleasure , ” “ Appalachian banana , ” and “ piteous man ’s banana tree , ” the pawpaw is a member of the Annonaceae , or custard orchard apple tree family that admit cherimoya , Annona cherimola , and graviola , aka soursop , A. muricata(mentioned above ) .
And while the fruit has an appealing flavor , there are some masses for whom consumption make stomach worried . This is due to the chemical chemical compound annonacin , which is also present in the bark and seeds .
TheNC State Extensioncategorizes the level of toxicity from exhaust pawpaw as low , with the summary : “ yield edible but some people suffer terrible tum and enteral pain ; skin annoying from manage fruit . ”
In addition , the flesh and twig hold acetogenins , metabolic compounds toxic to some genus Cancer cells . However , Sloan Kettering propose its cancer patient : “ There are no published clinical studies in humans to determine the safety of pawpaw for cancer treatment , ” and move on to warn patient role who wish well to consume the fruit that they may go through allergic reaction , neurotoxic gist , or vomiting if they do .
papaia fruit perishes quickly after ripening , so it is not presently a unglamourous food market storage commodity . Instead , it ’s the area of small - scale farmers and habitation growers who often issue it to Fannie Merritt Farmer markets .
In addition to fresh yield and icy pulp , selection are usable in lozenge shape for the purported purpose of boosting cellular telephone wellness .
Professor Bruce Bordelon , of the Department of Horticulture and Landscape Architecture at Purdue University , concord with the warnings and says , “ When it comes to pawpaw , perhaps it is best to savour the fruit in moderation . ”
“Way Down Yonder”
At a distance of up to six inches , the papaw is North America ’s largest native yield .
It ’s an overlook legacy from Mother Nature that harks back to gentler times , when bonneted fille and straw - hatted boys went fruit pick in plain foot on summer mornings .
Where , oh where is pretty little Susie ?
Way down yonder in the pawpaw dapple .
Theseold Appalachian lyricshave been sung around many a campfire , including the Girl Scout jamborees of my childhood . But although I was in prime pawpaw territory , I grew up with only the word , and not the angelical relish , on my knife .
So , what ’s a pawpaw patch ?
A. trilobais a works that thrives in organically - rich areas along waterways , in woodlands , and on hillsides , where the ground is specially moist . It may have the habit of either a tree diagram or a shrub .
As an understory plant , beneath the fond shade of deciduous trees , it is bush - like . Butin the full sunshineof undefended place , it ’s a Pyramids of Egypt - shaped tree diagram that may transcend 30 feet in height .
Both case generate suckers that grow into extra plants and finally form a thicket of growth , or the proverbial maculation .
Pawpaw Pioneers
My first forcible coming upon with this plant , no lie , was in my sister Susie ’s backyard . Yes , after peach about them for old age , she grow up and planted a patch of her own .
And in my area , the fruit is gaining popularity thanks to an organization called thePhiladelphia Orchard Projectthat plant and supports community of interests orchards in the city of Philadelphia .
Athens , Ohio grower Chris Chmiel bunk Integration Acres , the “ humankind ’s largest Asimina triloba processing plant . ”
I recently see Chris speak as a Edgar Guest on theGastropod podcast , in an episode entitled “ Pick a Pawpaw : America ’s Forgotten Fruit . ” Because the fruit is so perishable , his squad picks , processes , and sells it fixed . Buyers admit craft brewers .
Chris has revived interest in this under - cultivated yield by founding the “ big pawpaw festival in the earth ” and apportion its folk polish .
It seems that the location of patches in the wild and the names of places in the “ pawpaw bash ” support the theory that Native Americans not only forage for the fruit , but likely cultivate it as well .
From other American days to the offset of the 20th century , ethnic music scooped the sweet flesh from good skin to make jams and pudding , finding it plentiful in the wild . Herbal practitioner used the toxic seeds , bark , and leaves in a kitchen stove of homeopathic redress , from insecticide to emetic .
In 1916,The Journal of Heredity ’s Contest for the Best Pawpawsinvited participants to send their local varieties to the American Genetic Association . Prizes were award for the sound , and they were read for potential generation .
Over the yr , the early trailblazer of propagation died , commercial viability did not come to fruition , and enquiry wan . lamentably , at least 35 cultivar identified between the nineties and 1960s are now extinct .
It was n’t until the 1970s that serious stake resurface . WhenWest Virginia University works genetics scholarly person Neal Petersontasted the yield , he was inspired to peck up where former investigator had left off .
In 1999 , he partner with Kentucky State University to behave the Regional Variety Trial , with the cooperation of numerous university , to evaluate cultivar for possible commercial-grade production .
Today , Peterson continues his study , cultivating , researching , and instruct in theKentucky State University Pawpaw Program , and Peterson ’s Pawpaws are widely uncommitted for the household gardener . expectant - scale of measurement commercial-grade production stay on a goal of the future tense .
A Patch of Your Own
Are you ready to revive a once - celebrated native yield in your outdoor landscape ?
Here ’s everything you need to recognize to ensure success .
Soil Requirements
For optimum termination , you ’ll ask moist soil with a achromatic to slightly acidic pH scale that is organically fertile and drains well .
Contact yourlocal extension officeto have yoursoil tested , and adjust pH andadd amendments like compostandnutrient - ample fertilizerper the instruction in your trial story .
Location Selection
To originate a tree , opt a positioning in full Dominicus . It should be somewhat sheltered , either by a nearby construction , fencing , or shrubbery , becausehigh wind is lie with to damage pawpaw , permanently twist its subdivision .
matured proportion may turn over 30 feet grandiloquent and 20 feet across-the-board , with thick branches for a conic form .
For cultivation as a shrub , select a partially shaded localisation beneath a canopy of tall deciduous trees , where looser , sprawling growth has room to roll .
Pollination and Fruit
make up one’s mind whether you are interested in fruit , because pawpaw pollenation poses a challenge .
The sound method to guarantee a fruit crop is to plant at least two completely dissimilar cultivars on your place ( and three is even upright ) , as well asan regalia of nectar - ample plants that attract pollinator . The professional atPeterson Pawpawsrecommend planting tree no more than 30 foot aside .
The horticulturists at theLadybird Johnson Wildflower Center in Texasexplain that pawpaw produces many flowers that seldom self - pollinate , and are in fact , “ ego - incompatible . ” rainfly and beetle are the major pollinators ofA. triloba , and growers have been experience to hang roadkill from branch to attract as many rainfly as possible .
Another method of pollinating is to apply a paintbrush and manually pollinate melon tree blossoms of one variety with those of another , a technique that ’s beyond the scope of this article .
Rodale ’s Ultimate Encyclopedia of Organic Gardeningsays there ’s an former cultivar called ‘ Sunflower ’ that does n’t command ill-tempered - pollination , if you may chance one !
Quality Plants for Best Results
After your website is selected and the soil educate , it might be tempting to find a groundless pawpaw patch and dig up a seedling to take home . This is not a good idea , for two reason :
First , the plant has a farseeing taproot that may be damaged .
secondly , plants delve in the hazardous rarely transplant well to the home garden .
Per Carla Emery , author ofThe Encyclopedia of Country Living , if you find some mature yield , merely put it in the ground whole and spread over it with a thin layer of territory . If seed sprout , lose weight them out later .
Like many seeds , those ofA. trilobarequire a period of cold stratification to germinate . But unlike many seed , they must be keep moist . So , establish whole fruits post - harvest in the fall addresses both issues .
However , even if they do grow , plant and fruit produced from wild seeds are probable to be inferior to today ’s cultivar . These cultivated change are breed for desirable characteristics like disease resistance and exceptional fruit timber .
Also note that the seeds from modern varieties , particularly crossbreed , produce uncertain results , and often carry no resemblance to a parent industrial plant .
Another propagation method acting is to take a stem cut ( scion ) from a Sir Herbert Beerbohm Tree or bush , and ingraft it onto sturdy rootstalk ( dead ringer ) .
Planting Directions
Spring and fall are the ideal times to put plants in the priming coat , when the trees are hibernating . Here ’s how :
Pests and Disease
Pawpaw is not prone to pests or disease , especially when you start up with a plant that has been like an expert spawn .
Fungal or bacterial leafspot sometimes occurs on leaves that are too plastered for too long , and may be treated with a Cu - establish antifungal agent . Be sure to choose one that is good for use of goods and services on edible fruit .
The pawpaw peduncle woodborer ( Talponia plummeriana ) is one of the few gadfly that specifically targets this coinage . The larvae consume part of the flower when the tree diagram are blooming , which leads to a smaller crop .
Spider pinch , hornworms , various caterpillars , andJapanese beetlescan all attack the leaves .
Care and Maintenance
If you initiate from seed , it may take a dyad of month before you see a sprout , because the longsighted tap root word grows first .
Water profoundly once a week during the growing season , andmore if rainfall is scant . You may implement a stretch all - determination fertilizer to seedlings per packet education .
The expert atUniversity of Kentucky College of Agriculture , Food , and Environmentsay that first - year seedlings are very sensitive to ultraviolet light and require shading from intense sun , as well as mulch and coherent tearing during dry spells .
They also urge that suckers , the new shoots beside the main trunk , be hand pulled , as opposed to being clip or mowed , because the latter methods encourage more to produce . Of course , if you require a patch , leave them alone .
likewise , fruit that flow and decay contains seeds that may sprout . hit unwanted seedling by mitt pulling .
In spring , employ a layer of mulchto aid in keep the grease moist . Pruning is not ask , except to remove dead or damaged branch . However , as yield set on new outgrowth , some people crop in an endeavor to increase yields .
You may fertilize mature trees and shrubs each outpouring with an all - determination , dull - passing granular fertilizer . Sprinkle it in a roach a few column inch out from the base of plants . Asweeds commence to grow in summer , crystalize them away to inhibit pestis and disease .
Be patient when look fruit . It may take up to eight years before it appears , although some of the newest cultivars fruit much earlier . Take care to maintain even wet while fruit circle , as a drouth may cause it to suddenly overleap off .

Harvesting Pawpaw Fruit
pin is harvest prison term in the pawpaw maculation . There is variation among the unlike cultivars , but September is by and large peak pickin ’ time .
This is when green yield begin to buffer , loosely turning chickenhearted and then brown .
It ’s hard to bonk when to pick , and many folks use the prison term - honored technique of stir the tree or shrub and deal home whatever falls off . Do n’t pick too before long , because a pawpaw ripens well on the tree diagram , and may not mature further after harvest .
You have about two twenty-four hours to eat up your craw before it protrude to rot , so do n’t macerate any time ! plainly slice the fruit lengthwise , remove the seed , and smooch up the sweet , creamy , yellow mush for a truly tropic sensation .
Freeze any flesh you ca n’t consume fast enough . you may use it in everything from breads and cakes to mixed drinkable , ice cream , and charmer . I do n’t recommend infrigidation because fruit picked ripe are on the wand of rotting , and pass off a strong , albeit fragrant odor .
