There seem to be a lot of people with problems getting Goji berries to fruit. Like Bob I planted mine in good garden soil and was rewarded with vigorous growth and no flowers, one shoot was 7ft long. I have now consgned it to very poor soil in a sunny spot. indications are they do need as much sun as possible. Amongst theories I have come across for non fruiting are:
1] A very poor flowering clone is being sold in many British outlets.
2] like Blue berries you need two different varieties to get a good set of fruit.
Not heard of Goji berries needing ericaceous soil, try re-poting with a lot of grit a a little top soil.
