lumber trees put their push into growing up to the canopy . Orchard trees , on the other mitt , selected to be little and spreading , put their vigour into the output of nuts . Here ’s a sampling of nut varieties and their characteristic to aid you choose the good nut trees to grow on your farm .
1. Almond (Prunus amygdalus)
The Prunus amygdalus is have-to doe with to apples , pears and peach — the blurred almond Cordell Hull even looks like an unripe peach . super other blooming relieve oneself almonds susceptible to killing frosts . They do well in a hot , dry mood , such as California ’s Great Central Valley . sweet almond tree produce nut in about five years and can progress to about 25 feet grandiloquent . They must have two cultivar for crisscross - pollination and are pollenate by Honey bees .
2. Chestnut (Castaneasp.)
Before chestnut blight nearly pass over out the North American chestnut ( C. dentata ) , it comprise a quarter of all trees in the Carolinian forests of North America — through the Appalachian Mountains and into Canada .
Today , plant scientist are attempt to bring chestnut Tree back from the brink , backcrossing the North American species and blight - tolerant Asian species , such as Taiwanese and Nipponese chestnut ( C. mollissimaandC. crenata , respectively)—both of which also get in the U.S. depend on which of the K of cultivars are constitute , chestnut will mature in regions as far northward as Michigan , Wisconsin and Canada and as far south as Georgia and northern Florida . Depending on the variety show , chestnut grow 40 to 80 feet panoptic and high , though the size of this new salmagundi under development is n’t yet make love .
“ chestnut are very easygoing to grow , ” says Sandra Anagnostakis , Ph.D. , a chestnut scientist at the Connecticut Agricultural Experiment Station “ A chestnut plantation will need less investment in spraying for pests than , say , apples or peaches . ”
The substantial limitation is soil type and tolerable wet .
“ They can be rise in property with acid grease , [ but ] in places , such as California , where the soil is indifferent , only a few cultivars will do well , ” she says . “ If you ’re gooselike enough to buy a seedling tree diagram , you ’ll expect for 10 years for them to start flowering and fruit . If you buy graft trees , they ’ll come out fruiting the 2nd yr , ” says Anagnostakis . “ Since they ’re all ego - sterile , you have to plant two unlike cultivar — both of which will produce pollen for cross - pollination . You ’ll also have two dissimilar kinds of nuts and perhaps two dissimilar crop times . ”
Bill Reid , Ph.D. , nut tree crops specialist at Kansas State University , sees two disadvantage to chestnuts , which he laughingly calls “ the potato of the nut macrocosm . ” One is the unpleasant fragrance of chestnut flowers and the other is disposing of the prickly bur or husk . The chestnut come down when the husk suppurate and split course , still on the trees . The empty husks will go down to the solid ground subsequently . The shells or skins of the nuts can be strip off with a knife or even bite through with your teeth , if you ’re eating them crude .

Edible chestnuts are not related to horse chestnut tree .
3. Hazelnut (Corylussp.)
The cob , or filbert , do best in temperate climates , but hazels call for 800 to 1,200 gelidity hours to bloom and split quiescency . Too far south , they may flower too too soon or out of episode with pollination . Although hazels bear both manlike and distaff flowers , they are not ego - pollinating and need at least two different cultivars because some cultivar wo n’t pollinate each other . agriculturalist should engraft four to six unlike cultivar to get reproducible crop .
In America , eastern filbert blight fungus has limit commercial hazelnut woodlet to Oregon ’s Willamette Valley , but the growing of blight - resistant and cold - hardy hybrids may activate the hazelnut to become a sustainable crop for much of the United States and southern Canada . The plant life can be a 3 - foot bush or a 30 - foot tree diagram , count on rootstalk and pruning . Grafted or layered hazel will start develop within two to three years and can remain productive for 60 year .
Disease - tolerant and cold - hardy cob have the potential to become a valuable part of the sustainable - agriculture movement , according to Tom Molnar , PhD , cobnut expert at Rutgers University .

“ We ’re proper on the border , ” he says . The Tree are very low input , “ something that you could take care of on weekends . ”
filbert require only a few ( if any ) sprays for bud mites or blight , compared to grapeshot , Prunus persica or apple , and need much less pruning . Most hazels mature naturally as large multistemmed shrubs . Even with a bush , you ’ll still be able-bodied to harvest a crop , says Molnar . But if sucker around the groundwork are pruned two or three clip per yr to leave a individual Sir Herbert Beerbohm Tree trunk , all the DOE goes into the ripe wood , which equals more florescence and sooner bearing . Single - trunked Tree are also easier to maintain for grass control condition , mowing the grove and harvesting .
“ They ’ll do really well on stain that are pretty acidic , and they respond very well to nitrogen plant food , ” Molnar says . Weed control will keep trees intelligent , but his test trees have n’t take cuss control .
Hazelnuts are drought - tolerant and will get where other crops wo n’t , such as on slopes and in fringy soils .
Molnar admits that set more than 1 acre or so may not be a impertinent investment , as proceeds consistency is one of the things being tested in Rutgers University trial .
“ But there ’s a lot of electric potential , ” he says . “ For the hobby or backyard gardener — for your own expenditure or raise for a local farm market — I think it ’s a slap-up works ! ”

4. Hickory (Caryasp.)
The Carya ovata hickory ( C. ovata ) and shellbark ( C. laciniosa ) hickory are easterly North America natives , swan from southern Canada to northerly Mexico . They are tardily - develop trees that may take decades to bear nuts but can live for hundred . Grafted hickory varieties may yield more true but not faster nut output . Hickory tree diagram need a very prospicient taproot before they can start out produce junkie .
hickory tree are very cold - hardy , adapt well to interrupt areas and tolerate piteous soils . They get small , gratifying screwball within extremely sturdy shells . The tree diagram grow to about 60 feet magniloquent . You have to engraft two varieties whose flowering and pollen - shedding suit of clothes each other ’s pollination timing .
5. Macadamia (Macadamia integrifolia)
The macadamia tree , introduced to Hawaii from Australia in the later 19th century , can also raise and produce well in modest neighborhood of southwestern California and southerly Florida .
6. Pecan (Carya illinoensis)
The pecan is another member of the hickory category . An extremely slow - growing specie , it takes years to found the monumental root system it needs before it can begin to grow wood and may take five to 10 eld to bear nut . The trees can live 130 years or more and originate 90 feet magniloquent and 120 feet wide — really ! Pecan trees can be cultivated and grow well outside their natural stove , which is from Texas through Kansas , Missouri and Illinois , but need a pile of summer day- and night - clock time heat . They are self - pollinating , though round the bend from bad-tempered - pollinated Sir Herbert Beerbohm Tree may be of higher quality .
For Reid , “ Pecans are Martin Luther King Jr. ! ” Husk removal and disposal are not a problem with pecans , which he believes are peerless in taste .
For farm on the northern edge of the pecan zone in Oklahoma , Missouri , Kansas and Illinois , he commend Kanza , a cultivar that he helped publish in the mid-1980s . It ’s scab - immune , ripens early in a enceinte surface area of the land , and grow an excellent medium - sized nut that fills the center no matter what the rain normal .

“ Once they get up to size , you do n’t do yearly pruning , ” he says . Maintenance pruning is to “ keep them from make you in the head when you ’re mow underneath . ”
“ Planting a pecan Sir Herbert Beerbohm Tree is an act of religion , ” he says . Even with grafted trees , pecans are among the slowest crop to found . Until they grow a massive radical system , the top of the tree wo n’t turn , Reid explain : “ It ’s only by about class 13 that you ’ll get ‘ Oh my good ! I ’ll have to commence doing something with all these nuts ! ’
“ I ’m shaking trees for nut production that are nearly 4 foot in diameter , ” he say . As trees get larger , they sometimes have to be thinned to give the remain tree room to grow ; “ If they shadow each other , nut product move to the very top of the Sir Herbert Beerbohm Tree . ” The Sir Herbert Beerbohm Tree must be fertilized every year and spray for insects and for disease , if they ’re susceptible .

Unlike walnuts and hickories , the stubble , or shucks , break and dry on their own once the first freeze run into them . “ Commercially , we let them dry out on the trees , ” says Reid . “ Once we put the shaker on the Sir Herbert Beerbohm Tree , the nut case just come out — that ’s the beaut of pecans ! ”
The hican is a naturally occurring hickory - pecan hybrid that try like a combination of the two and has a more - easily cracked shell than hickory tree . Hican trees can grow to 60 feet and may take six to 10 year to develop a crop .
7. Pine Nut (Pinus edulis)
Evergreen piñons or pinions , native to westerly states , produce kernels in their pinecones . Depending on the coinage and grow conditions , pine nut case tree may be large or lowly , fast- or tardily - growing , heat - tolerant or insensate - unfearing , and produce only a few or up to 200 pith per cone .
8. Pistachio (Pistaciasp.)
The slow - growing pistachio tree expand in regions with short , cold winter follow by hot , teetotal summers . Drought - tolerant , the tree grows well in desiccate sandy - soil regions of the American Southwest with plenty of Lord’s Day , where there are no frosts to kill its spring blush .
9. Walnut (Juglanssp.)
Walnuts let in the eastern North America native bleak walnut tree ( J. nigra ) , the butternut ( J. cinerea ) , the heartnut ( J. sieboldiana ) , and what is regionally referred to as the Persian , English or Carpathian walnut tree ( J. regia ) . Walnuts do well with full Sunday and deep , well - run out loamy ground and require 400 to 1,500 hours of cold weather , bet on the cultivar . They must be cross - pollinated . They can take three to five years to produce a crop and can live on for centuries . The trees rise 50 to 100 foot tall and wide , calculate on the variety . Because walnut tree trees ’ roots excrete a substance that inhibit the outgrowth of many other plants , keep them well aside from vegetable and flower gardens . Unlike other nut trees , walnuts should be pruned in the crepuscle . At crop , get into gloves — the stalk are dogged and leave indelible stains .
The novel walnut - blight - resistant cultivars create nuts that are five time bigger than the aboriginal North American assortment . According to Anagnostakis , “ you could usually put about 30 tree on an Akko , and at about 100 pounds per tree , that ’s a lot ! ”
