Mango dieback indoors
« on: February 04, 2019, 02:17:15 PM »
I have a problem with some mango varieties that they die back during the winter. I wonder what is the cause.
Watering is some when soil gets dry and the soil mix is optimal for drainage and aeration.
Plants flowered then died. Only the grafted top dies.
They were sprayed with fungicide in autumn.
Also made a drench with phosphonate.

I wonder what triggers the sudden death. Plants get dry fast and die in a couple of days.

Why drench with phosphonate. Roundup is a phosphonate and kills anything it touches

Round-up yes. But other phosphonates help fight against root rot and trigger self defense mechanisms.

A picture taken when the symptoms first start, might be helpful.
