If any of you are successfully fruiting Goji, please share your techniques!
I have some seedlings that I hope will fruit in a year or two.
There are reasons other than lack of pollinators that might cause the low
fruit. Goji are solanaceous, and in tomatoes, fruit set is temperature
dependent. The common wisdom used to be that they wouldn't set fruit if
night-time temperatures went below 55 F and/or if daytime temperatures were
above 95 F. That's true, but pollination biology is tricky. More recent
studies have found that the average daily temperature may also be a factor;
too much heat during bloom prevents fruit set. IN addition, a crucial time
is the week or two before blossoms open--too much heat, and the flowers
don't form well--pollen can be sterile, and other sorts of floral
abnormalities occur that prevent fruit set. In addition, humidity is also a
factor. So even though plants otherwise appear healthy, the weather before
and during bloom can cause problems.
John, where are you growing these?
