Lack of water: no, on a drip line every 2 days.
Sun: no way, this is the SoCal, summer time in its brightest.
Heat: I wish, 90-100 every day, the nights (65-70) are too warm I would say also.
What's left? I was thinking some fertilizer and that is what I started to give a little. Will see.
All those suggestions are very good points, thank you!
Instead of some other varieties to try to extend the fruiting season. That's easy to try now.
