Candycots Puzzle

Here are two pictures of the same Candycot tree.  The first limb has lots of fruit and will need to be thinned.  The remainder of the tree barely has a fruit to be found.  We are trying to unravel the mystery of getting them to consistently produce.  Older plantings are doing better so it may just be a matter of maturity.

The fruit is so remarkably good it is worth the effort to figure out the puzzle of production.  I will be trying different irrigation and fertility regimes to see what works best.
