No Mangoes growing in Sydney (forum)

Tommo starts with ...
Hi. I would love to know why my Bowen Mango has not produced in nearly 5 years. The tree use to crop abundantly but all the small fruits now fall off after they are about 3-4cm. The anomaly is not just with mine. None of the mango trees in my suburb and surrounds have produced fruit for the same period. I'm in Sydney near the coast. Is it rain related, global warming or something far more sinister. Thanks, Tom

Hi Tommo,
Mangoes can crop this far south, but they're out of their comfort zone which is the tropics. When the weather is raining a lot or just cold during flowering time the flowers will go mushy and diseased resulting in little or often no fruit. There's a guy in Waterfall who has quite a few mango tree varieties, but nowadays he's mainly active on FB. He'll answer your questions. Have a look at his photos to get ideas.

I'm in Willoughby and I've had fruit every year off my young R2E2 seedling mango, but this year only 3. Around here almost all the mangoes have zero crop this summer and last summer. I suspect Bowen (aka Kensington Pride) is worse affected.
It is common to spray before flowering with copper oxychloride to improve your chances. Pruning after fruiting season to open the canopy to sunlight is also helpful. I've also noticed that older trees almost never have fruit around here.

The problem is mainly the fungal attack by anthracnose which is exacerbated by rainy weather (as usual for fungal problems). This year the weather was particularly wet in Sydney, hence the damage to flowers and fruit which drops off while still very small. Improving air flow through the foliage by strategic pruning will help but regular spraying with fungicide will also be necessary. Most mango varieties are unfortunately susceptible to anthracnose and also black spot. I have found that the Kwan variety is a lot better in this regard and is a good choice for Sydney. Bowen is very susceptible.
