When do you trim hawthorn bushes?

If you are trying to get the vines to spread, trim the areas you do not want them go, as often as you see fit. The untrimmed "runners" will continue to grow towards the early sun if possible. Actually moving the "runners" by hand, and guiding them in the direction you want them to travel, will help alot. Honeysuckle is a VERY hearty plant. You really have to go out of your way to kill it. P.S. If you do not like bees "hovering" around, please go out of your way and transplant or terminate the plant.
