Looks good and in developing well. The grass looks like guinea grass. I think there is scope for putting extra Eugenia's. jabs, various sapotes, maprang, abiu, guavas, longan, citrus, Annonas and a few others in a way to ensure year round production and diversity of the best fruits. Did I say Garcinias? I guess spreading suphur strategically would be bit expensive but as a water additive it could work. You can select the N fertilisers that are most acidifying also.
