I have three vines in the greenhouse in pots, all growing well but they are not bearing any flower stems at all. This is their second year, and I was told that maybe there is a problem with the soil ph what is the best fertiliser to use to give the vines the right conditions to produce flowers? The varieties I have are Bianca, Rembrandt, and Boskoop glory. Thanks
