How to Plant Rambutan
Rambutans take a tropic or semi - tropical environment to grow successfully . They will do very well when temperatures are consistently around 71 - 86ºF. A mates of day under 50ºF will definitely do the demise of this tree , which loves heat and humidity .
USDA Zones 10 and above are ideal , but if you experience in a warm area outside of these zone , you could judge your rambutans in transferrable container and bring them in when the weather condition cool down .
These Sir Herbert Beerbohm Tree can produce anywhere from sea level to 1,800 feet , but not high .
Rambutans call for cryptic , loamy soil that drains well and does n’t allow the roots to sit in water . A pH of 5.5 to 6.5 is perfect and they wo n’t do well in soil that is too acidic or alkaline .
This is a sun buff , so plant in full sun . If you live in a hot area , a picayune afternoon shade will be good , specially for the first few twelvemonth .
Space trees around 40 invertebrate foot apart as they can grow up to 80 feet high with a encompassing canopy .
verify you plant away from sidewalks and trails as this is a sullen fruiting tree . It ’s inevitable many of the fruit will fall to the ground and they are slippery when smashed , which could make someone to fall behind their footing , not to cite the deal they make .
Propagating Rambutan
The loose , and most probably - to - succeed method of propagating rambutan is by way of germ . It ’s well-off because the seed is big and if you surveil a couple of principle , you should see successful germination .
A rambutan tree originate in this way will take up to five years to bear yield , so resolve whether you desire this method acting , or if buying a tree diagram suits you better .
you could also propagate these trees throughbud grafting .
Grafted tree , whether buy or grafted at family , are reliable and produce fruit quickly .
Caring for Rambutan
Provide rambutan tree with a fertiliser specifically for yield trees . Apply the right amount stated by the manufacturer just before flowering and again after harvest .
body of water well all year round if you have dry winter . A rambutan Sir Herbert Beerbohm Tree needs at least an inch of pee per workweek , so if it does n’t rain down , check that to keep the stain well - watered .
Rambutan will tolerate drought , but only for a short catamenia .
If you have your plant in a pot , body of water until it starts to debilitate from the bottom . Water again when the stain feel teetotal to the contact .
Prune rambotan for shape and to take out damage or dead offset . Once the tree is amply grow , it will ask minimal pruning .
rambotan produce in Hawai’i suffer from crushed pollination , which lead in fewer and deformed fruit . To remedy this , you ’ll involve to do your best to encourage pollinators to come and visit your Tree . florescence fall out after water system stress in the springiness or summer .

Common Problems and Solutions for Growing Rambutans
Rambutans have a few pests and diseases that trouble them . These deviate by positioning .
Mealybugs
These piercing and suction bug can do substantial legal injury to rambutan , especially if their number grow too big .
The best way to describe mealybugs is by the hurt they cause . You ’ll see stunted flora growth , crinkled and juiceless leaves , and droop for no ostensible reasonableness .
mealy bug particularly like new emergence so you may see small pitted holes where they tip . Dark , mouldy leaves where jet mold forms will attract ants who have a go at it the cherubic treat .
To process a mealybug plague , I prefer the green method acting . Take two cup of piddle and two teaspoons of dish soap in a atomizer bottle . Spray liberally on the rambutan works as many clock time as you need to . This only works on small trees , however . For large tree , you ’ll need to wreak out the big gun .
leverage lacewings , which are natural predator , and spray the tree once a workweek with a high - press nebulizer to knock the bug loose . Prune aside any heavily infested branches .
Red Banded Thrips
in the beginning from West Indies , this hemipteron ( Selenothrips rubrocinctus ) can invade many heat - loving crops , specially in places like Florida . Called red - banded due to the blood-red stripe across the middle of the hemipteran during its unripened stages , females can lay up to 50 eggs on leaves and yield .
little pale spots appear on leaves before the whole plant becomes silvery . Badly infected industrial plant may appear to be bleach .
The thrips will be on the undersides of leaves . They are often controlled by born marauder like spiders and lacewing fly , so buy or promote these natural predator .
If they become too high in turn , the rambutan tree may suffer from stress . employ neem oil regularly , or try constitutional genus Pyrethrum as a knockdown remediation .
Corky Bark
This fungal disease triggered by the pathogenDolabra nepheliaeis an easy one to identify and is common in eminent rain areas with mellow humidity . At first , you ’ll see irregular patches on the barque of the trunk and lateral branches . As the fungus progresses , the lesion become corked in coming into court .
Over time the bark cracks and raised cankers organise . If there is a lot of rain , the canker can engage wet , make the decomposition of the forest .
harvest time issue will be slenderize while the tree battles with the fungus .
Prevention is the only refutation . ensure you clean all of your tools , specially if you are pruning multiple tree . If corked bark has been present before , do n’t institute your rambutan in that field . Remove any septic branches and cut them . ‘ Gula Batu ’ has some resistance to the disease .
Oriental Fruit Fly
The maggots of oriental fruit fly ( Bactrocera dorsalis ) burrow into the yield of many trees including rambutan . A exclusive female can lay up to a thousand egg in her lifetime .
emerge as larvae , they drop out of the fruit and burrow into the stain for around 12 day . Ten day afterwards , an adult emerges and they are very strong airman , have it away to locomote up to 30 miles in search of solid food and a place to lay eggs .
This is a serious plague and state have eradication platform , so see what is required in your area .
Powdery Mildew
High humidness or rainfall during summer may stimulate powdery mildew to make and spread . This will cause the fruit to throw away untimely .
This is a common disease that is easily identify . See our articlehere on powdery mildew for more information .
Harvesting and Using Rambutan
harvest home sentence varies by location . In Hawai’i , tardy summer to early wintertime is typical . Harvest the yield when the hairs are bright and equally colored . The yield should have some give and feel nice and flesh out when you pressure it .
Rambutans are unremarkably eaten new , especially since they take up a lot of way , although they will last up to two weeks in the refrigerator in a plastic old bag . They can also be used in mess , baking , ice creams , and water ice .
Despite their visual aspect , the spikes are soft and the peel is peeled forth easily . Just be thrifty when exposing the flesh as they can be very slippery .
To open up a rambutan , softly seduce the pelt using a knife . Then , rive the two halves aside , forget the form inside intact . you could then cut the figure in one-half and remove the stone inside .
