Mango tree not fruiting

    37 responses

Bern Johnson starts with ...
Hi, thanks to Daley's Fruit Tree Nursery for setting up this forum. This is just what I need.

I live in Caloundra and have a huge mango tree at the back of my house. When hubby and I moved here, we were told to get the tree pruned, as this had not been done for a few years and this would encourage fruiting. We were also told that the first year after the big prune, that we should not expect any fruit from the tree. Well, two years on, the tree is still not fruiting.

Can anyone give me some help as to how to get our tree to fruit please?

With thanks

Hi there, we also have a mango tree in the garden that has apparantly not fruited for a couple of years it has a few flowers on it now but the neighbour says these usually fall off before having a chance to fruit. It is very large, do you think i have to prune it back to let the sun get through? Hoping someone can help!

Mango fruit set depends on several facters. Temperatures below 10 deg when flowering in the spring will reduce fruit set. Also wet weather during flowering can result in anthracnose infection which will cause fruit not to set. To get around low temperatures in Spring during flowering, one can remove the first flower set and this will result in a 2nd flowering a month later when temperatures are higher. Hope this makes sense Claire.

Hi, to force the plant to bear fruits, apply potassium nitrate. (10 gram / litre of water) spray on the leave

My one Mango tree was here when I bought the house in 2001 and in early 2002 we had over 200 mango's-juicy and beautiful.
In 2003 I was lucky to find 20 on the tree. Since then I have had none.
Now there are a lot of tiny green ones.
How do we look after them??
What can we spray on the tree?

It would be interesting to see a picture Jo. One at a distance and also up close of the newly forming mango's. It is easy to upload to these pictures to this forum.

Depending on the size of your tree you could give it a bi-weekly spray of copper oxychloride this time of year this stops powdery mildew and anthracnose from hindering fruit set.

Perhaps have a look at your mango tree and see if there are any signs of leaf deformation or the mango's having black spots that shrivel up and die.

My biggest problems are possums eating the mango flowers and the newly forming green mangoes.

Another thing about some mango's is that some seasons they will fruit much better then others. We have a huge "string" mango tree next to us. And every couple of years they will get a bumper crop that fills up a wheelie bin each week then other years barely at all.

Also if you are going to water your mango it is best to do so early morning or during the day rather then late afternoon. Otherwise the water sitting on the leaves overnight is a perfect breeding environment for fungus.

Here's some pictures of my mango tree. A lot of the flowers have turned black and only some little green mangoes can be seen. We have just had a week of heavy rain. Today is the first sunny day in ages. Would this be bad for the fruit??

Took a picture from the other side of the tree.
Thought I'd mention that my nearest neighbour has a lot of fruit trees and his peach tree is heavily infected with fruit fly and he's not doing anything about it.
Is it true that a string of garlic would help the fruit fly stay away??

Not all flowers turn into fruit, so it is quiet normal for a lot of the flowers to abort. The fruit that has set should be sprayed with a copper fungicide to protect them from Anthracnose. With regards to Fruit Fly, you could use Naturalure to control fruit fly. Its an organic control but does need to be applied weekly through the fruit fly season. Ideally it would be good for your neighbour to use it too.

I have a mango tree in my yard about 12 years old. It flowers at least nine months of the year (even in winter) It has flowered every year in the past five to six years but no fruits.

Last two years it set some fruits but as they got larger they split and got spoilt. so In March this year I gave it the chop (almost) and removed most of the branches. It has some leaves now. Well if I don't get any fruits next year it is a goner!

Howdy all

I have a mango tree I inherited from the property purchase this year. It is my first year so I got some tips from the previous owners.

1) Use a product called blood and bone (it's actually a soil mix of some sort). You can use this for all citrus fruit bearing plants as well.

2) Don't fret about the fruit that do grow and fall as there is only a 50% success rate of fruits reaching maturity.

3) Finally in the off season ie after this summer (use the supermarket as indicator of mango availability as it is seasonal) give it a good trim and strategically trim it so it grow good new branches that will later be used as stepping branches.

The neighbours actually mentioned that the previous owners trimming made the tree look quite bold to the extent that she was using a chainsaw.

Hope these helps and good luck. I'm lucky enough that I have 20 or so fruits but surely the drought up here is not helping.

Peter, are you from Castle Hill QLD?

I am in exactly the same position as you with a bowen mango tree. I have the following suspicions why it flowers but I don't get fruit.

1. Black Spot - Once the mango's start forming the black spot does as well and effects perhaps 40% of the fruit and this causes the fruit to abort. This is a very old variety of Bowen the newer varities such as the Dwarf Irwin Mango Tree are far superior. I have one in the pot and not one mango had any sign of black spot even though they are within 20m of each other.

2. Possums - Without doubt in the night lots of possums take to the tree and eat the flowers and young forming fruit. The mango tree is about 2.5 meters and unless you deter them from visiting the mango tree on a nightly basis there is no hope.

3. Early Flowering - In Brisbane sometimes it heats up for a few days just before spring which causes the mango to break out into flower. However then it cools down and this colder weather causes the mango to abort the flowers and drop the fruit. We knew about it this year so we pruned it heavily after the first flower and we got new flowers which stayed on much better then the year before.

Ronnie, I like the tip about the chainsaw. What variety do you have and do you have a picture for us? Also what did you mean by stepping branches.

What is your address in-case I am hungry and in the neighborhood one night ...... jokes:)

Hey Correy... not quite sure what type of mango tree it is but certainly it's not the long type of mango fruits that it is bearing. It's starting to take form of those that you find in the supermarkets. I'll find out though

I'll send you some pics tomorrow.. bit difficult to do at night.

Stepping branches.. well the previous owners pruned it so well that the branches that was once there and then pruned is now an easy footing for climbing the tree and picking the fruits. Will take some pics of these too.

Cheers...

I actually started surfing the net to try and get to the bottom of my non fruiting mango tree. It's a bowen and 4 years ago when we first moved in we got a lot of fruit then the next year not as many then none at all for 2 years now. I absolutely love mangoes so i just have to find out why I'm not getting any anymore.
I've been pruning the tree after Christmas every year to keep it small. There's no sign of fungas etc. any suggestions??

Hi again. Had a good look at my tree today and managed to find 1 (ONE) good sized mango and thats it! (about 9cm round so far)
We sprayed the tree with copper spray in November and it seems to have worked for this one lonely mango.
Fingers crossed.
All the other little green mangos either fell off or shrivelled up and died.

Hi Jo and everyone else, The pictures of Jo's mango flowers show typical anthracnose disease (I'll bet there were black leaves too) Anthracnose is a fungal infection, you have to spray regularly, not just once, from flowering right through to picking, usually Mankozeb, a copper spray or Fruit Care for us organic people.

If a fruit tree won't flower, fertilise with superphosphate.

Potash is for general good health, as it improves the quality of flowers and fruit; and strengthens the plant, increasing resistance to diseases etc.

Happy gardening, Dianna.

Hello Vishal, Your mango tree sounds like it's got anthracnose, it's got black bits on the distorted leaves and the flowers go black? This is a fungal disease, the spraying routine has been discussed here already. You need to fertilise your trees with a complete fertiliser suitable for fruit trees (nitrogen, phosphate and potassium) in June and August. In Queensland, we fertilise mango trees in December and February, so that's early summer and late summer. Good Luck with your mangoes.

Hi Anonymous in Florida, you can pick the mangoes when they've 'coloured up', then they should ripen in the kitchen, just put them in the fruitbowl on the table. You could also leave them on the tree and cover them up with a cloth bag, that works for me, it keeps the insects, flying foxes (fruit bats) and the possums away. To grow from seeds - plant the seeds in a pot, water it, and it should grow. You might find that from one seed, you get two trees so you'll have to pick the best looking one. They will then take many years to fruit, it would be quicker to buy a grafted tree and then you would get fruit in a year or two. Happy Mangoes.

We have a supposedly Thai variety of mango. Bought it small ( grafted) about four to five years ago and this year inApril it flowered in about ten clumps. Many of the flowers felll off in brisk winds and those that were left turned into tiny little mangoes, almost al;l of which have disappeared.
Do the trees have any norm for how long they take to first bear fruit? Is it possible to get a "lemon". . . ie one that doesn't bear ever?

Hello Peter in St John. I suppose it is possible to get a dud mango tree. Make sure you fertilised the tree properly, give it potash for strong growth and good health. Look for the anthracnose, blackened distorted leaves and flowers, you have to spray every fortnight to overcome that. Why do we always get windy weather just in time to blow the flowers or fruit off? If the tree is in good health (remember the potash), the fruit/flowers should generally stay on the tree. Cheers, Dianna.

We moved to our house 2 years ago and the first year got about 10 huge and absolutely divine mangoes from our very large tree. Last season the tree was covered in flowers and through the fruit started to form they all dropped after we had a shower of rain and we didn't get a single mango. The tree is just starting to bud again now. Should I spray with Copper spray and if so when? Also is it too early in the season for the tree to be getting flowers.

Mat, i don't think that's a mango mate - bark is too pink.

Worth saving this mango??
Dropped all it's leaves year ago.
Now monthly Fertilised with seaweed.
Possums continuously eating new shoots.
Tried regular bitter sprays.
Contemplating pruning right back
and Putting bird net over it.
Any other suggestions?
(how radical to prune, in stages?)

thanks, Andrei

Hello,

I had three lovely Mango trees in my garden and unfortunately one of the trees died and had to be pulled down. Now the second and third trees are showing the same problems (see photos). The second tree in particular has discoloured leaves and dead branches. I do not fertilize the trees. The picture of the leaves shows a leaf from the second tree (discoloured) and a leaf from the thrid tree (green).

Hope someone can help before I lose all three.

Tks

Jonathan

you need to water your mango fruit tree more often, the tree is feeding on it leaves. Give it also slow fertilizer for fruit trees, especially now is starting the growing season for flowering to fruitings, give it plenty of water daily. If you're watering it heavily then every 2 -3 days, but especially coming into the hot summer season, daily is best for it.

Cheers.

That's about it Kathie, they should also be nice and plump around the point at the bottom of the fruit. Don't worry about them being hard.

I have had good luck with Miricle grow every two week - 3-5 teaspoons a gallon to trees in distress instead of regular granular fertilizer( don't do both too close together). I have had a tree that received too much water because it was right next to a septic system tank - and it had leaf and brach die-back. I stopped watering that particular tree and used the miricle grow and it is fine. I had lost a previous tree with the same problems in that same hole before we discovered where the spetic tank was located.
