My wisteria vine was planted three years ago and is growing like crazy. Unfortunately, I've yet to have any flowers. Do I need to add something to the soil or fertilize?

You may need to prune your vine in order to coax it to bloom. These vines do not need fertilizer, as they will grow excessively--too much can also inhibit flowering. Check the light it receives, as too little will affect blooming as well.
