Started this plant from seed. It is now about 5' tall & wide. It fruited three years ago, had flowers two years ago, nothing last year at all (it was a very wet, warm year). No sign of flowers or fruit. Leaves look healthy. Anyone have suggestions to bring on the fruiting. It gets about 1/2 day sun in Central Florida.

if you have aphids i would NOT add fertilizer.
recent research shows excess nitrogen makes the cells of new growth elongated and the cell walls thinner, making it easier for pests to access the sap.
This goes for most fruit trees, and i believe other plants as well.

This is a great little fruit tree.
it rarely grows any larger than 8 or 9ft
doesnt really need any pruning, and provides a ton of healthy fruit.

My major peve is that it doesnt flower until July (In New Orleans zone 9)
and the fruit doesnt ripen until it starts to get cold
a second flowering might happen, but any frost will damage fruit.
this might just be the variety i have and the climate in New Orleans.

Help Request-
We live on the Coast in San Diego, and bought a Starfuit tree last week. It's a grafted Kari and about 6 feet tall. It had been growing in a greenhouse. When we got it home, we realized it had aphids. I used soapy water and think they are mostly dead. Now the leaves are yellowing and spotting brown, and about 1/4 of them have already fallen off. I was thinking this was because of shock in the transition from greenhouse to on our deck (very sunny spot)- but I'm not sure. Anyone have any recommendations? Does it need a little fertilizer to help it through this transition? If so, what kind. Any help is appreciated!

I have this plant growing indoors and it really makes a good-looking plant for decoration (You can see it in one of the photos). My plant was grown from a seed which I got from a fruit. Now the plant is four and half years old, about 1 meter (~40 in) tall little tree and is doing really well despite of dry indoors air.

I think that hardest part with this plant was the first winter - My plant dropped almost all leaves and wrinkled the rest so it looked quite bad. But it was still alive and had new growth coming. I think that the reason for this was that dry air combined with winters low light. Well, the plant survived its first winter, got tougher and carried on living.

This plant seems to need a little pruning now and then. Otherwise it likes to grow only upw... read more

I have not grown this plant. Averrhoa carambola is thought to have originated in Ceylon and the Moluccas; however in southeast Asia and Malaysia, it has been cultivated for many centuries. It is commonly grown in Taiwan, India, southern China, the Philippines and Queensland, Australia. It is moderately grown in Tahiti, New Caledonia, New Guinea, Guam and Hawaii. It is a naturalized plant in Puerto Rico.

I started this plant earlier this year from seed and it has really taken off quite well! A very pretty and airy plant, I'm going to try to overwinter it as a houseplant :) I'm posting a picture of it as well!

We moved into this house last February, a Northwest suburb of Houston, and it had two mature starfruit trees. They produced pretty constantly and today I collected two six inch ripe ones. These guys need to be pruned from the bottom. Can they be propagated by cuttings or even air-layering? I'd hate to waste any thing and we have space for more. Please advise.

I have no plant of this variety, but grows in some farms owned by others. To my knowledge, this is the season when it grows more and there is one farmer that dehydrates the fruits and sells. It tastes similar to the raisin and has a desirable level of sourness combined with sweetness.


On Jun 8, 2005, foodiesleuth from Honomu, HI (Zone 11) wrote:

I have found that there are (at least) two types of carambola trees. One produces sweet fruit and the other type is quite acidic. Fortunately, ours is the sweet variety.
I have used the fruit fresh, sliced or juiced and I have used it for making star shaped preserves.

my sister started our tree from a seed. everyone told her that it couldn't be done, but our tree is doing well and is only a few months old.

This has beautiful foliage that folds in at night. When the fruit hangs on the tree it adds even more to the tree's beauty. The fruit is delicious. It bears several crops a year. It is also quite hardy for a tropical fruit tree.

The fruit is absolutely delicious and refreshing! We have bought an area to build our house, and theres a Star Fruit tree growing there under the large branches of a big Cashew Tree. We are planning on keeping it. I have already had one from that plant, and it was good. I hope to keep having fruits for many years


On Sep 22, 2002, IslandJim from Keizer, OR (Zone 8b) wrote:

The fruit, like no other, has a nice thirst-quenching ability. The tree needs, above all, good drainage. And that means it needs an application of minor elements at least twice a year. Also, grafted varieties produce consistently larger fruit that ripen more evenly. My largest fruit in 2001 weighed in at 21 ounces.


On Oct 1, 2001, Floridian from Lutz, FL (Zone 9b) wrote:

Carambola grows well in a wide range of soils. It requires adequate moisture throughout the year but does not tolerate waterlogging. Regular fertilizer application is necessary for fruit production. Carambola is non-seasonal and yields 3-5 crops per year. The fruits are harvested between 40-50 days after fruit set, when they are just beginning to turn from dark green to a light yellow-green.
