Simon,
My Lemon Zest (thanks for the scions) on LaVern Manilla rootstock also had heavy PM this year. Maybe we should cut off the first bloom to force a late 2nd bloom in warmer month -- May or June instead of March/April. Maha and Cat are the ones with minimum PM grafted on the same tree.
Sapote, you just have to be careful how late you want to push it because if you prune too late, it could get out on you which isn’t necessarily a bad thing if your tree is still small. Normally my LZ tree will naturally flower twice a year. I mainly prune to remove the end of the branch where the previous flower panicles grew because they can harbor fungal spores.
Cat mango might be CAC/COC, I spread some scion around a while back. CAC/COC is an absolutely delicious mango that grows well here and has been disease resistant from reports I hear back from people I shared scions with.
