Blueberry Tree Blooming

[athena24]

I have been struggling with my two blueberries for two years now. Very slow growth. I am hoping next year they will take off. I have specific southern rabbitteye varieties for TN and I have spruced up the soil considerably. You know, this year I actually got a sucker growing from one of them, however, they have not grown in height. I have put pine needles as mulch this summer and that works so much better than the regular mulch. The pine needles seem to keep the moisture much better. I would like to hear others success stories with blueberries and what they have done. Mine are not quite a success story.
