These tropic yield have a dulcet , floral flavor with juicy build . While you may sometimes buy these fruits in the store , they ’re phenomenal overbold off the tree .
If you live in a warmer part of the US , you’re able to grow these trouble - free trees and enjoy the fruits by the handful .
Ready to get word more about the lovely longan tree ? Let ’s chute decently in .
Best Longan Varieties
Longans are related to lychees and have a sweet , fruity flavor . The trees can handle cooler temps than lychees , but the fruits are smaller and slenderly less sweet . The tree themselves are beautiful , with glossy , dark green leaves .
There are many varieties of longanberry , some well suitable to grow in the US than others :
Planting Longans
Longans can only outlast in tropical or semi - tropical regions . They thrive in warm weather and anything less than 24 ° degree Fahrenheit will probably down this tree diagram , and will certainly result in hoar hurt . It grow best in USDA Growing Zones 9 - 12 .
you may grow Nephelium longana in Puerto Rico , California , Hawaii , and Florida . In their aboriginal environment , they can grow up to 100 feet tall , but they stay on closer to 40 foot tall in the US .
The sound type of soil for longans is plenteous , sandy , loamy earth that drains well . The pH should be slightly acidic . remediate your land at least three times as wide as the pot the plant is growing in when prepping the country . If you experience in an area with a miserable water table , create a prominent mound when planting to assure the roots will be above the water mesa .
Planting Seeds
If you ’re using the cum from an existing longan fruit then you should pick it thoroughly and let it dry for four solar day . If the seed is old than a week old , it might not germinate , so plant the right way away .
Plant in a mixture of equal part sand and moss in a nine - inch container . Water well and place in bright , collateral sparkle . You should see newfangled increment emerging within two weeks . Harden off for a few weeks once the industrial plant is about six inches marvellous .
allow the plant life outside in the pot for two years . verify to keep the seedling watered and feed with a balanced fertiliser as it rise . After two twelvemonth , you may found in the ground during the sleeping winter season .
Be aware that trees grown from source wo n’t grow true to type , but you ’ll still stop up with a lovely harvesting .
Planting Seedlings
you may purchase longan seedlings , and this is a sure room to get your paw on the cultivar you favour . Amend the soil with plenty of sand if it is n’t already quite sandy . Keep 40 feet between plants .
Alternately , you may plant your seedling into a larger container and grow it indoors . expend a mixing of moss , sand , and perlite . set the container somewhere the tree will encounter at least six hours of sunlight each day .
Caring for Longans
Caring for any works requires your time and energy . But once they ’re establish , Dimocarpus longan do n’t actually need much in the way of care . Water , eating , and pruning are your primary chores when growing Dimocarpus longan .
Of naturally , as with any plant , you require to water longan tree ofttimes if you do n’t have regular rainfall . The amount of water will change count on the location , clime , and humidness stratum in your area . If you acknowledge that the upper inch of grease is juiceless , that ’s a sign that it require to be watered .
These trees can handle some flooding , but not drought , specially when they ’re untried .
Fertilizer
Use a balanced fertilizer with an NPK of 6:6:6 or 15:15:15 . Fertilize once in the spring and once in the summer in the first year . In the following year , inseminate every six - eight weeks .
Weeding
If you ’re planting outside you ’ll need to be conscious of weeds . Every few calendar month , head out to your Sir Herbert Beerbohm Tree and hand pick any weed that have popped up . Weeds compete with the tree diagram for nutrients and water , but longans have shallow origin , so you do n’t want to till widow’s weeds .
Pruning and Thinning
In addition to weeding , pruning is also essential to keep your lungen tree in the honest condition . You should off any utter or diseased branch right away . If your tree has lots of dull branches , you might want to thin matter out a slight to encourage airflow .
You should also remove any shoot so they do n’t percolate nutrient from the immature tree diagram .
If you have a lot of fruits work on one panicle , thin out a fourth to a half of the small fruits to encourage larger fruit ontogenesis .
Pests and Diseases
sound longans are less susceptible to plague and disease , so do your best to keep going your growing tree during times of focus such as drought . Here are the most usual problem to watch for :
Lychee Webworm
This recently discovered pest ( Crocidosemaspp . ) was bring in into the US from the Caribbean . The grownup is a moth that is active in the former evening . The larvae feed on the buds , flush , leave of absence , and shoot of the longan and litchi plants . They also thread protective webs that further restrict photosynthesis .
Go out and inspect your plant for worms or webs starting in November and spray any web or bug off the tree with a blow of weewee . Then , rake up the debris and dispose of it in a certain old bag . If the plague is too large to parcel out with in this fashion , use a spray containingBacillus thuringiensis(Bt ) .
Root Weevils
There are several species of root weevil that feed on longan , includingDiaprepes abbreviatus , Pachnaeus litus , andArtipus floridanus . Not only do they harm the tree as they tunnel into and feed on the root word , but they leave openings for fungal infections to invade .
Treat with Bt the 2d you see the clusters of egg on the freshly - mold leave-taking .
Scale
Most of the time scale insect ( Andaspis punicae , Thysanofiorinia nephelii , Morganellalongispina , Coccusacutissimus , Coccus longulus , Saissetia coffeae , Ceroplastes cirripediformis , andPhilephedra tuberculosa ) are n’t a giving lot , but if your plant life is stressed or insalubrious , scale can pop to build up and harm longan trees .
born predators usually keep graduated table under control and an plague takes a long time to build up , so you have plenty of time to stop things before they go too far . The challenge is discern these insects , because they ’re fairly immobile and sting to one spot .
If you see coal-black mold , shank dieback , or greensickness , take a unspoilt look for ordered series worm . If they ’re present , treat withhorticultural oil .
Algal Spot
Algal spot , caused byCephaleuros virescens , causes dark-green - hoar lesions on the leaves of the plant . As the disease progresses , it releases crimson fungal spores that make the stem turn and leave see red . Eventually , the stems might split . do by with neem oilto control the algal spores .
Harvesting and Using Longans
The best part of grow longans is , of course , when you get to glean the fantastical fruit . The fruits on longans are round with a large seed in the center , though the size of it of the seed can vary depending on the cultivar . The flesh is sugared , gamey , and flowered .
Longans want several years before they ’ll start producing a harvest . Once they ’re ready , you should start to see fruits in early to late spring and the harvest time should be ready by mid to late summer . Some tree diagram produce an off - season crop in the surrender .
Longans are known for producing hard one year and then lighter the following year . The harvest can also be impacted by temperatures during the class .
To glean , clip away the clusters of fruits by hand . The fruits need to be ripe before you cull them because they wo n’t mature off the Sir Herbert Beerbohm Tree .
Enjoy the fruits bracing , on yogurt or desserts , or made into Indian relish . you’re able to also free or dehydrate the fruits to keep for later .
