This year butterfly bush is very tall, but all of the bloom have dried up very quickly from the stem to halfway up the flowerhead. What has caused this. Also, how much and when should this bush be cut back after the blooming season? Should it be cutback before winter or in the Spring? and how far from the groundup?

You can prune your butterfly bush in the early spring just as new growth begins. You can prune as much or as little as you'd like. Some gardeners prune theirs down to ground level each spring, others prune it back by one third or one half. I'd prune it back now by about a third to encourage healthy new growth and new flowers. If the flowers are drying up too quickly your plant may be heat or water stressed. Hope the next flush of flowers lasts longer. Enjoy your garden!
