checked my redcurrant bushes on monday---after 2 and a half years they have finally bore fruit---the clusters looked healthy and blooming---checked them today and half the fruit is gone, leaves chomped and swarms of ants all over--have they ravaged them cos i cant find any caterpillars anywhere??
Pigeons or other birds would be my guess. The birds aren't really bothered whether the fruit is fully ripe or not. Try netting the bushes. Ants don't eat plants - the leaves probably have some aphids which exude a sweet liquid that the ants feed upon.
It's what happens to my gooseberries. Always forget to net and the pesky bullfinch get my buds
thanks for your help---made the mistake of thinking the birds wouldnt touch them till they started to turn red---netting now in place
