Longan fertilsing and watering

[Hylo]

I have a small longan tree(Chompoo marcott) that is flowering (Early spring).
Should I be fertilising and pumping the water into it now or wait until fruit develops first?

I kept getting allot of small fruit on my trees.
I was showed that the branches frequently have 3 pannicles of flowers per branch and when the
fruit is small cut 2 pannicles off and leave one pannicle per branch.
I wouldn't be concerned with fertilizing now but water is really important
It was not easy to cut off 2 pannicles and leave one but the fruit size was
really nice this year.
I have seen very large trees that were loaded with large fruit that were
not getting extra water. Eventually in Florida the tree's roots find water

Thank you for the advice. The tree fruited last season...with only some small fruit. I'll trim the pannicles as you suggest and pump in plenty of water.
Cheers
