Pineapple pleasure and Sugarloaf are shy bearers…period. Are they worth growing, absolutely. They’re a nice size fruit with amazing flavors. I am speaking from my personal experience in SoFla. I don’t have them in SoCal.
I harvested 19 mangos from my 3 yr old Sugar Loaf last year (planted from a small 7 gallon). I would say that was good production for a young tree. Also, no sprays were used.
I love reading about people in Miami area not having to use sprays & having nice clean fruit with little powdery mildew problems.
Read some material on powdery mildew and most indicate most growth starts above 60F and tapers off at 80F with little growth above 85F...
Congraduations on your warm climate... Unfortunately Martin County, Florida has more days/nights in the 60F to 80F range (80F to 86F is tapering off growth rapidly) and IMO is why we have more Powdery mildew with more chance of fruit drop vs. fruit set than you in warmer Dade County, Fl; unless we spray spray spray lol...
one of many google info pages:
https://hgic.clemson.edu/factsheet/powdery-mildew/Sunlight & above 86 degrees seems to do wonders in killing a lot of the powdery mildew in Dade County etc.
My one pineapple please (pleasure? lol) was topworked but I let a few branches regrow and now have a mixed tree about 6 yrs old... Blooms easily, gets powdery mildew etc. very very easily, drops baby mango fruits the easiest.... Unfortunately is still at zero fruit but maybe next year lol..
5 LZ and 2 set a fair amount of fruit last year but as mentioned a lot of bloom & drops on other 3 trees now probably 5 yr old.
5 yr old Phoenix is identical in zero fruit making maturity but also only 1 tree that I opened up for air flow this year after spring fruit set failure... Probably just my location for temperature and lack of consistent fungal spraying for all these varieties mentioned at my Martin County, Fl location...
