The second bud here.

The two little guys together.

More pictures of the Soursop blooms. I have no idea when they will turn to become fruit and what a fruitlet looks like.

Another picture of the same bloom.

Has the bloom dropped off and a tiny fruitlet is forming? Any idea for those who grow Soursop?

I have a potted Soursop for 8 + yrs so far no luck .It's been trying but the little fruits always fall off.

So far so good. Try giving them some trace elements. Often those can make a difference in successfully setting fruit.

Developing fruit.

Thanks, Tropicalbreeze for the feedback and suggestion. I'm glad that the tiny knob there is the fruitlet. I gave trace elements to the plant a couple of months back before the blooming. Should I feed it now again? I've heard that twice a year of trace elements is good enough while a monthly compost tea is helpful. What do you think?

I'd agree, Trace Elements aren't called "Trace" elements for nothing. A bit of Potassium is good, but I think compost tea is good for that anyway.
