[NAFEX] Illinois Everbearing

When you summer prune, you are probably pruning off buds in which
flowers that will bloom the following year have already been initiated.
The process of floral initiation in mulberry is discussed in
Moriculture: Science of Mulberry Cultivation by Kichisaburo Minamizawa:
He says it takes 50 days for the mulberry tree to initiate floral
primordia. I do not know, however, whether the tree maintains this
ability throughout the growing season. It may be affected by
photoperiod or some other environmental factor, with the ability to
initiate floral primordia diminished toward the end of the growing
season. So, pruning too late into the growing season may decrease the
number of flowers and fruit production the following year. -- Sam

Everyone talks about how heavily this tree bears fruit, however I have
had a different experience.
I purchased an Illinois Everbearing from Stark Brothers in spring 2003.
The tree now has a trunk of about 5" diameter; I have summer pruned it
to keep it as a 12' wide, 10' tall heavily branched bushy tree. During
June- August , I find 3-5 ripe fruits on it per week.
I do not consider this heavy bearing, although I assume that I must lose
some whole fruits to birds.
What do people mean by fruiting heavily. Is my experience typical?
