I disagree.
My Manzanos have full southern exposure.
HOT roots I think are the real problem.
They won't set pods in heat but that isn't a problem for me.Here in S.Ca. I grow year round.
I get spring and fall pods.
Mite infested plant-still kicked out the pods,picked 50+ pods at a time for several weeks off these 2 plants..
Larger pots (True 20 gal/+ pots) work better for me.
MITES LOVE manzanos/Pubes.
Gotta get out your loop and look at your messed up leaves.
75% of the time it's mites messing with your plant even if other plants don't seem to have them.
Mites zero in on Pubes for some reason=more tastey?
Heat messes with pod set and roots big time.
Mine have no problem with full sun-in big pots.
Only Pube that is bullet proof is Ecuador Pubes.
They fruit heavily,early in big OR small pots.
Small pods but thick as grapes...
