Lychee Fruit

You say that lychee fruit is very sweet, but the fruit that I bought in the store is bitter and unpleasant tasting. Why is this?


Lychee fruit does not ripen after picking, unlike other tropical fruits such as mangoes, avocadoes and bananas. If lychee fruit is picked early it is almost always bitter tasting and often leaves an unpleasant aftertaste. Often times large commercial fruit growers pick their fruit prematurely in order to get it into the marketplace when the wholesale prices are higher.

If lychee fruit is properly harevested, at the peak of ripeness, it is delicious, sweet and fragrant. Taste statistics indicate that 91% of people who try properly ripened and harvested lychee fruit find the experience excellent.

In our experience small Florida growers who focus more on quality, rather than profitablility, produce the best lychee fruit in the country. Do to our unigue climate conditions Florida is the lychee growing capitol of the US and one of the only states where they can be successfully grown. We recommend that you buy direct from Florida growers or look for the "Fresh From Florida" logo if you are buying lychees in a supermarket.


What is the correct way to eat a lychee?
As fast as possible so that you can move on to the next one. Actually, all kidding aside, we like to bite a small piece off around the stem and then squeeze the fruit so that the aril (the fleshy part around the seed) pops into your mouth.
What is the difference between a lychee fruit and a lychee nut?
Lychee nuts is a name that usually refers to dried lychee fruits but is not really a nut. A true nut is actually the edible seed of certain fruits. Lychees are much tastier when eaten fresh; however, when you can't get fresh lychees the dried lychees are a great alternative.
Are lychees healthy & nutritious?
One cup of fresh lychee fruit has only 125 calories, more of the antioxidant Vitamin C than oranges or lemons, about as much dietary fiber as an apple with the skin on and is loaded with potassium. 
When is the season for lychee fruit?
Lychee season is during the summer, May & June in South Florida (northern hemisphere) and December to February in Australia (southern hemisphere). On average the season lasts about six weeks at the most.
What should I do after I receive my fresh lychees?
You should immediately place the lychees under refrigeration. If you do not plan to eat all of your lychees within the next several days you can freeze them. Frozen lychees are also very delicious and taste like a fine sorbet. If you freeze them even in months like November and December they still taste wonderful. You should enclose them in a zip lock bag.
Can you freeze lychee fruit? 
YES! Lychee fruit is wonderful when frozen. Frozen lychees are like a fine sorbet. We bring frozen lychees to parties during the holidays and we never have to take any back home with us.
 
How do you freeze lychee fruit? Whole with skin on or do they need to be peeled first? 
You can freeze them with the skin on. I put mine in Zip-Lock freezer bags. The color of the skin will turn a brownish color, but it doesn't effect the taste of the fruit. I have never peeled my lychees before freezing them so I don't know what effect that would have on them. I image they would not last as long peeled because the tough skin on the outside act like a suit of armor protecting the tender fruit inside.
If I am diabetic can I eat lychees?
"It's hard to beat a fresh fruit salad, papaya, pears, apples, oranges, Chinese plums, mango, longan and litchi. Fruit is an excellent source of fiber, vitamins and minerals, and has zero fat. Everyone, including people with diabetes, should eat three to four servings of fruit a day." This is a quote from the article "Diabetic Guide to Chinese Food" in Diabetic Gourmet Magazine 
Some of my fruit have small seeds and many more have large seeds. Is this situation normal?
Yes, small seeds are the exception in the case of Brewster lychees, however, despite the predominance of full size seeds the Brewster variety is a larger fruit in general and has a higher flesh to seed ratio than many other varieties. Mauritius lychees have small seeds, but they are also a smaller fruit. Ha-Kip lychees tend to have a predominance of small "chicken tongue" seeds and Bengal seeds are relatively small.
Why does my fruit have stems on them?
We find that the fruit keeps longer when some of the stem remains. If the stem is pulled off this can rupture the skin of the fruit accelerating the spoiling process. 
Will I get sick if I eat too many lychees at one sitting?
When we pick lychees we eat almost every other fruit that we pick. So far none of us have ever become sick. Su Tung Po, the greatest Chinese poet/painter of the Song Dynasty, wrote a poem while he was exiled in Guangdong province in Southern China for his politically satyrical writings, wrote a poem about consoling himself by eating 300 lychees a day.

 

 Lychee Trees

Can I grow a lychee tree in my area?

Lychees grow best in South Florida, Hawaii, southern California and southern Texas. However, it never ceases to amaze us at how many people all over the country are successfully growing a lychee tree outside with a little freeze protection, or indoors in a greenhouse, atrium or sunny spot.
Lychee trees require approximately 100-200 hours of chilling below 68 degrees mean daily temperature in the winter to set fruit. They are subtropical and cannot tolerate temperatures below 30 degrees for more than 8 hours. If it hard freezes in your area you will have to provide some type of freeze protection for your lychee tree.

We encourage people to experiment and explore new ways of growing lychees here in the US and we are happy to assist and provide support for anyone trying to grow a lychee tree(s) in less than perfect conditions.

What is the best variety of lychee tree to grow in the US?
The Brewster and Mauritius varieties have proven to be the most reliable both to grow and to produce fruit and are the primary commercial varieties in the US. Lychee enthusiasts all over the US have reported to us that their Brewster & Mauritius consistently outperform other varieties. You will get better fruit set from cross pollination if you have more than just one variety so if you get two we recommend a Brewster & Mauritius.

The Sweetheart variety has a large red fruit with a small seed. We highly recommend this variety if you want just one lychee tree for your yard. The future of the Sweetheart for commercial production looks good, however, the variety has not been around long enough to have a sufficient track record yet.

The Emperor is another variety that has been doing quite well in the US and is a great container lychee tree. The feedback we have been getting is that the Emperor variety is quite hardy and does not require as much water as some other varieties of lychees do. The Emperor is most likely a "mountain variety" of lychee tree.

In Hawaii the main commercial variety is the Kaimana because the growing conditions in Hawaii differ from that of the mainland US.
How do I plant my lychee tree?
For details on how to plant your lychee tree read this article: How to Grow Lynchee.

How do I take care of my lychee tree(s)?
A lychee tree is as healthy as it root system. The root system is not only to hold up the tree but the primary of the roots is to absorb the water and nutrients that feed the tree. Feeding the soil and the soil food web feeds the lychee tree.
How long will it take for my lychee tree to produce fruit?
Lychee trees produced from air layers should begin fruiting the very first season. However, the first few years that you have the tree you should trim off most of the emerging fruit so that the young tree can focus it's energy on growing rather than producing fruit. After two or three years you can let the tree produce fruit normally. Maximum fruit yield begins after the tree is about 10 years old.
 Lychee
How much fruit does a lychee tree produce?
The fruit yield for a single lychee tree varies with age, variety, weather/climate, pollination and growing practices. The older and more established the tree is the more fruit it will yield annually. A backyard lychee tree can produce 50-200 pounds of fruit per year, but will most likely not produce the same amount of fruit every year. In a good year, a lychee tree in commercial grove conditions in South Florida can produce between 400 and 800 lbs of fruit.
How big/tall do lychee trees get?
The optimal height for a lychee tree is 10-15 feet. Some commercial growers keep their trees at 6-10 feet tall. Lychee trees can grow up to 30 or 40 feet after about 25 years or more, but it gets very difficult to pick the fruit on a tree that large. There are even lychee trees in China that have grown to 100 feet tall. If you prune your lychee tree you can keep the tree at any size you desire.
What climate conditions do lychee trees grow best in?
Lychee trees do not tolerate hard freezes (below freezing for more than a few hours), but do like chilling in the winter. Between 30 & 40 degrees for at least 40 hours during the winter is the minimum for getting the trees to consistently produce fruit. Also, lychee trees need full sun. Shaded areas of the tree will rarely produce fruit.
How much winter chilling does a lychee tree require to produce fruit?
A lychee tree needs approximately 100-200 hours of chilling below 68 F (20 C)degrees mean daily temparature in the winter for lychee trees to grow bloom spikes instead of leaf flushes.
Can lychee trees tolerate freezing temperatures?
No, lychee trees are very climate sensitive. If you are growing a lychee tree in an area that experiences freezing temperatures in the winter you must use some type of freeze protection. Lychee trees will die if they are exposed to a hard freeze below 30 degrees for more than 8 hours. They do however require some chilling in the winter to produce fruit.
Should I prune my lychee tree?
Yes. Prune your tree after harvesting the fruit to develop a nice tree shape, control tree size and promote strategically timed growth flushes.
When is the best time to prune my lychee tree?
Prune your lychee tree every year in the summer right after you harvest the fruit.
I want to buy a lychee tree for my yard. What type should I get?
The most reliable fruiting and most popular lychee trees here in South Florida are the Brewster and Mauritius which comprise most of our grove. Get a lychee tree that has been grown from air layers, not grafted. Only buy bare-root air layers if you are a skilled tropical fruit grower.
Can I graft a lychee tree?
Lychee trees are difficult, but not impossible, to graft. The most effective way to propogate lychee trees is by air layering. For more info check out the "About Lychees" section of this website for our article on Grafting Lychee Trees.
Can I plant the seeds from my lychee fruit to grow a lychee tree?
Yes and No. You can certainly plant the seed and it should sprout into a tree. Seedlings are fun to grow. However, your seedling tree will take 5 to 20 years to produce fruit and there is a possibility that it may never produce fruit at all. If the tree does bear lychee fruit the fruit may not even retain the good characteristics of the original fruit that you ate or planted.
Do I need more than one lychee tree to produce fruit? 
No, you only need one tree because lychee trees have both male and female flowers on the same tree and can be self pollinated.

How to Grow Lynchee.



The Lychee (Litchi chinensis) is a tropical fruit tree in the soapberry family. It is native to southern China and grows wild in Indonesia, the Philippines and Vietnam. It is an evergreen that grows to 15 meters and bears edible drupes that are more than an inch in diameter. This fruit is red or pink with a large seed that should not be eaten. Here's how to grow lychee fruit.


Instructions :

1. Ensure the planting site will have full sun and a temperate climate. Mature trees can withstand only a light frost and young trees will need to be protected from cold, heat and high wind.

2. Select rich soil, with deep alluvial loam being ideal. The pH should be around 6.5 and lime may need to be added to reduce the acidity.

3.
Keep the soil moist but well-drained. The lychee can withstand brief flooding but not standing water. The water table should be at least four feet below the surface and continually moving.

4. Propagate the lychee primarily by air-layering. Girdle a branch of a tree and allow it to callus for one to two days. Apply a mixture of sticky mud and chopped straw or dry leaves and wrap it with burlap.

5.
Water the branch frequently so that it develops roots. Cut off the branch after about 100 days and increase the diameter of the earth ball to about one foot. Grow the air layer in a sheltered nursery for more than a year before gradually exposing it to full sun and setting it out in the orchard.



5 Tips for Growing Lychee Trees in Containers

Lychee trees can be grown in containers, even though it is not the optimal growing conditions for them. Here are some tips to help you keep your lychee tree healthy:
  1. Lots of Sunlight 

    Your Lychee Tree will grow the best in full sun on all sides of the tree. If you are going to put your lychee in an area with sunlight on only one side you should turn the tree as often as possible. Lychee trees in containers grow very well outside where they can get full sun around the entire tree.
     
  2. Fertilizer 

    We don't recommend fertilizing your containered lychee tree very often or your tree will quickly outgrow its container. Low concentration, organic fertilizers like kelp and fish emulsion are best. When you do fertilize make sure you spray minor elements on the leaves. Spray liquid phosphorous fertilizer on the leaves when you transplant your lychee tree into a new container and annually in September or October to promote flowering and fruiting of the lychee tree. As you probably know, the pollinated flowers become the fruit.
     
  3. Mycorrhizal Fungi 

    The soil quality in potting mix is nothing like the original natural forest environment of lychee trees in Southern China. If you grow a lychee tree in a container, you must take measures to improve and rejuvinate the soil quality or your tree will slowly die within a few years. Mycorrhizal Fungi is a soil treatment that will increase the roots ability to absorb and distribute nutrients and water and innoculate the tree against many plant diseases and pathogens.
     
  4. Trim the Roots 

    Once a year take your lychee tree out of its container and trim back the roots. Even if you are moving your lychee tree to a larger container, you should still trim back the roots. If you let the roots of your containered tree grow uncontrolled, you risk having an unhealthy tree. When the roots are all matted together, the root system does not breathe or absorb water and nutrients evenly which can eventually kill your tree or cause it to decline.
     
  5. Flower Pollination and Fruit 

    In order for your lychee tree to bear fruit, you must to have a way to pollinate the female flowers. Outdoors bees, wasps, and other insects do the job for you. In our grove we have large beehives to make sure that our grove produces fruit every year.
     

    If your lychee tree is indoors or in a screened patio, you will have to manually pollinate the flowers if you want fruit.

 

 

 

Fresh Lychees straight from the tree in midsummer is one of the true delights in life.
Brought to North Queensland by Chinese gold diggers late last century they have remained unknown to most Australians until very recently. It is only now that they are being grown commercially and starting to find their way into the better fruit shops in season, that some Australians are being privileged with a taste of these irresistible little delights. Many people have tasted canned lychees as served with icecream in Chinese restaurants, but rest assured the canned ones just cannot be compared to the real thing. The lychee tree is very attractive, Evergreen, medium size with a rounded crown and dark glossy foliage. Variety Bengal has bright pink new growth.



HOW LONG DO THEY TAKE TO BEAR ?

Some varieties take several years, but the variety Bengal will bear in three years. Of course this crop is only small but the Lychee is a long lived tree and each year the crop will get bigger. For example, at six years, the average yield in NSW is 10 Kg , at 10 years, 42 Kg and so on.


WHERE CAN I GROW A LYCHEE TREE ?
Lychees will grow in a very wide range of soils from sand to clay base.  They prefer a sheltered (from wind) but sunny spot and need a clear space of at least 4 metres (all around) the trunk.

DO THEY TAKE FROST ?
Lychees will not stand heavy frost especially when young. If well sheltered with a guard for the first two winters or until the tree is 1.5 M (five ft) high, it will then stand light frosts to -1 degrees.

DO THEY NEED SPRAYING ?
Lychees are relatively free of pests especially in the home garden or mixed orchard situation.  The main thing to watch for in young trees is scale insects.    If you only see a few scales don't worry because they are  probably being controlled by insect predators.  If you have a heavy infestation it is best to spray with a recommended chemical for scale but be careful because Lychee trees are sensitive to some chemicals.  If the scale is being spread ("farmed") by the common little black ant, then you may solve the problem by drenching the soil around the trees with something recommended for killing ants.

DO THEY NEED PRUNING ?
Occasionally the branches need thinning or selecting for good open crotch angles but this only needs to be done every two or three years.

WHEN DO I PLANT A LYCHEE TREE ?
Best to plant Lychees in early to mid summer - that is, about November to February, so that they are settled in before winter. Do not expect much growth in the first twelve months as they are slow starters.

ANY SPECIAL REQUIREMENTS ?
Yes. Lychees have no drought tolerance whatsoever.  They must be kept moist at all times.  Whereas most trees will wilt when dry, then recover sometime after watering, the Lychee will not recover from a dry-out, but will drop its leaves and eventually die.

HOW DO I PLANT MY LYCHEE TREE ?
  1. Keep well watered in pot until planting.
  2. Dig a larger hole than pot size, and work in 1/3 bag well rotted or processed manure.
  3. Place tree in hole after removing the pot, and fill around so that all the roots are covered.  On no account disturb the roots !
  4. Water in very well.
  5. Spread 1 Kg dolomite around the tree on soil surface.
  6. Mulch soil surface around the tree.
  7. Do not stake the tree, but if it is in a windy area, erect a wind guard around the tree.
AFTERCARE.
  1. Keep well watered.
  2. Fertilize frequently during first four years but only a little at a time.  Lychees are susceptible to any kind of sudden shocks.  A sudden large dose of fertilizer can cause them to set back badly.
  3. Protect from frost and cold winds in winter until 2 metres high.
