Hi everybody from Germany. I am an amateur container gardener. Last year bought a small blueberry plant full with beautiful buds. Had noticeable harvest the same year. Checked online what to do for winter time, pruning was what I was recommended. But this year till now what I have is just a healthy beautiful blueberry plant, all foliages and not a single flower which means no harvest. Beginning of the spring time , l lifted up the plants and added some berries soil but It sets all canes. Please help me.
