Mango trees

[Elisa Wood]

We have a fairly large mango tree that did not produce any mangos last
year although it did produce lots of flowers. I have also notice that
none of the mango trees in my area (Brisbane) produced any mangos last
year. This is our second summer in Bris so not really familiar with
these trees. Is there anything I can do to increase the chance of fruit
production. The tree looks really healthy.....to me anyway.

Thanks
Elisa

Elisa,

The same has happened here in Gympie. There are five large mango tress in
the gardens of house next to mine and for the last two years they have
flowered well but did not set any fruit. I believe that this is due to the
heavy rain we received in both of these years during the flowering period
and I seen to recall reading this causes the growth of a certain fungus.

Regards..Charles.

Hi Elisa,

I am not an expert on mango trees but I do know that of all the flowers
produced only about 1% or less will potentially bear fruit (admittedly
hundreds of flowrs are produced in any single season!). Mangoes dislike
humid or wet weather when the flowers are at the pollination stage. Low
temperatures will also cause flowers to drop prematurely. While mangoes
flourish in sub-tropical Brisbane their leafiness is often at the expense of
fruit. A great shade tree here but they really produce much better in truly
tropical climates.

Martin.

g'day elisa,

they seem to pretty finicky in our back yards as far as fruiting goes.

here in brissy we had some fruit last year, a few more the year before
when we had good easter rain, and below average after that. this year
none at all although i did prune them pretty heavy in march after the
new growth had stopped they needed to be opened out. the 2 trees over
the back yard haven't fruited anyway and they did have a few last
year.

i lived in rocky for 6 years and a similar situation the year we had
good easter rain they fruited by the ton, the mango orchards there
are west of rocky in a fairly dry area they get irrigated with drip
systems they get them to fruit every year.

i think when we get too much rain after easter and before xmas they
seem not to fruit reall good if at all.

i did speak to a horticulturist who didn't shed much light but
indicated that all things ahd to be equal, rain at the wrong time
causes them to drop developing fruit or not to fruit at all.

My understanding is that nowadays there is a mango tree disease called
Anthracnose? which is widespread in the SE Qld area. This shows up as a
black fungus which spreads over the flowers - resulting in no fruit. I
believe that it is possible to spray chemicals to combat this disease - but
not really practical for home growers because of the size of the trees.

Last year, our small tree gave us a few mangoes for the first time - but
this year there wasn't even any sign of flowers.

Barry, we have that same problem here at Flaxton, near Maleny.
If you get a wet September, the fruit seem to reach the size of peas,
and then fall of the blackened stems.

Next season, we intend to spray with a Copper compound, either the
Sulphate (Bluestone) or Bordeaux mixture. The latter won't wash of the
trees with a light shower.

I have also heard that hammering a copper nail in the tree will also
inhibit the fungus. These nails were (are?) used in boatbuilding.

Beware of building up too much Copper toxicity in the soil, however.

Hope this helps.
