Is there anything more satisfying than walking out to your yard picking something to eat? Growing starfruit may very well be one of the easiest fruits you can grow in Florida.  When friends ask for a fruit tree suggestion, this is always in my top three.  Now, there may be limited uses for the overwhelming harvests of fruit, but that is when you become the most popular coworker, friend and neighbor!  Starfruit or Carambola

We planted our small tree in the spring of 2012 and after a little more than two years we are regular picking fruit and certainly have more than we could ever eat.  You can see in this comparison how quickly starfruit (also called Carambola) trees will grow.  Today our tree is about ten feet tall, so almost all of the fruit is still within reach when we really get on our tippy toes.  Over the next few months I will trim the leader branches to help keep the size more manageable for our space.

Tips for growing starfruit.  With Growing Starfruita little bit of luck and some searching, you may be able to find a small tree that is already 3-4 feet tall.  If you are able to find one this size it is very likely that it will produce fruit the first year that you have it.  If your small tree starts to set a bumper crop of fruit, it is time to be ruthless and remove some of those developing fruit

Growing Starfruitwhile they are small.  This will help the tree to continue to focus on developing a strong root system rather than putting all of it’s energy into growing fruit.  Some experts will suggest removing ALL fruit the first year, but let’s be honest, that’s just not going to happen for most of us.  The anticipation of picking your first starfruit is just too overwhelming!

Fertilize your tree regularly as starfruit are heavy feeders.  I prefer to use a palm fertilizer because it has all of the micronutrients that fruit trees need.  In this photo you can see an early sign of nutrient deficiency starting to show on the leaves.  Fertilizing every 3-4 months at a low rate will keep your tree growing well.  You can learn more in the University of Florida’s publication hereNutrient deficiency on starfruit

Starfruit trees will flower almost continuously which means there will be several harvests each year.   While the flowers aren’t the most showy, you will certainly notice a lot of bee activity around your tree when its flowering. Those bees are crucial in pollinating the small pink flowers- go bees go!  Not every flower will set fruit, so don’t worry if there is a strong storm that knocks some of them off.  The continuous supply of flowers means that you don’t have to worry about losing an entire crop due to bad weather. Growing Starfruit

I was surprised to read that you can induce fruit set by selective pruning.  Our tree flowers and sets fruit almost continuously, so I am not sure this is necessary, but always good to know!  Pruning the willow-like long shoots (“whips”) or selecting a small diameter limb and removing all the lateral shoots from this limb to their bases will induce flowering in about 21 days and fruit approximately 70-80 days later.  Also, fruiting may be induced on whips by bending them from an upright position to a lateral position, clipping off the last 12 to 18 inches of growth, and clipping the leaves off but leaving a small (1/3 inch) piece of the petiole (leaf stem).

The mild winter weather the past two years has helped our little starfruit tree to grow continuously.  A small cold snap last year caused a few leaves to drop, but overall the tree has been in good health.  According to UF, “Air temperatures of 30° to 32°F may kill young leaves; young trees, twigs, and mature leaves may be killed at 27° to 29°F. Small branches may be damaged at 25° to 29°F, and large branches and mature trees may be killed at temperatures of 20° to 24°F.”  If we get to 24° there are bigger concerns than our little tree!

Harvesting Carambola. Fruit are ready to be picked when they have a rich yellow color  They should pluck easily from the branch and won’t require very much pull to release.  If you have to tug on the fruit it probably means they need a few more days to ripen.  Branches with a heavy load of fruit may start to pull toward the ground, so if a single branches has more fruit than it can hold, simply remove a few and let them ripen on the kitchen counter to take some of the weight off your tree. Carambola as a garnish

What do you do with all those starfruit? This is a really good question!  While we eat a lot of them fresh, just like an apple, there is really no better way to show off than to use them as a beautiful garnish.  Sliced crosswise, the characteristic star shape really stands out and looks great against a dark plate or spread on a salad.

I’ve recently found a few other recipes that sound interesting- let me know if you’ve tried them and how they turned out!

  • Starfruit Chips from Epicurious.com.  I haven’t had anything bad yet from Epicurious so I look forward to testing this recipe.
  • Carambola Pickles from the Food Network. Huh.  I don’t know what to say about this… I guess it is worth at try.
  • Star Tea.  Yep!  This is the first one I will be testing. Sounds delicious and looks beautiful.
