I have Mauritius lychee that has been in the ground for 7 years bought from local nursery in 15G, that has grown to reaching the house roof line and beyond. It produced “decent” crop in 2019, but none in 2020 and only a few dozen fruits for 2021 and even less this year!
The tree seems to be a healthy looking and still growing, but the last 3 years it has not been producing enough fruits to speak about.
So, I am puzzled with it, perhaps someone(s) would offer some suggestion of what should I look for that may help increase this tree’s fruit production?
