my red and black currants don't produce fruit!

[JudyH]

I live in Australia a moderate climate ie in winter we can almost get a frost and in summer the temperature is fairly pleasant. I have 4 bushes of black and red currants and they are 3 years old. I have never had any fruit. Could someone tell me if the climate is suitable, or is there something else I can do to make them fruit. Many thanks

It certainly could be your climate (not that I know anything about growing in a warm climate). What happens to the bushes in the winter? Do they loose their leaves and go dormant for at least a little while? If not, I wonder if they will produce the flower buds that will make the fruit. Have any of the bushes flowered at all in the spring?

One reference says " black currants will usually fail to fruit through lack of winter chill" and another cites USDA zones 3-6b as "suitable" climates; that is, with winter temperatures in the range of -40 to 0 F (-40 to -18 C)

(LOL, literally)
