Helen,

Other than feeding it with a bloom-booster type fertilizer, I don't know of much else you can do. Since it is in a ditch, there's always a chance it might be getting too much nitrogen in fertilizer that is leached out of surrounding areas during periods of heavy rainfall.

Is it a native one? Some of them don't bloom as heavily as some of the hybrids.

Sometimes you can force a honeysuckle into blooming by pruning it heavily, but that doesn't always work.

If it has recurring issues with powdery mildew or honeysucke aphids, both of those are known to impede bloom.

The native honeysuckles that pop up in dappled shade in our woodland do not bloom nearly as heavily as others that are in full sun, and they do tend to creep and crawl and sprawl at least until they find a tree to climb.

I was also thinking maybe it was getting too much nitrogen. That will cause heavy growth but very few flowers. Can you try and move it and put in a vine that likes more shade? Not sure how much shade you have, but that is probably an issue as well.

Mine is in part shade. It blooms! It gets neglected, it blooms. It gets heavily trimmed every year and it blooms. Last year most of it got a shot of Round-Up and that didn't seem to slow it down. I'll keep working at it though. LOL Would love to share the wealth.

I also have some that was already here when I moved here under an elm at the back of the house. This is an old home site. Both bloom in some places and act as a ground cover not blooming in others. There is no way I could move it and I should probably be trying to get rid of it as it is invasive, but it does smell really good when it blooms. The hummingbirds like it and I'd rather have it than cinnamon vine which also invaded. It is on poor rocky ground.
I think I will get my pole saw and try to trim the trees and I may some other day weed eat the top to "prune" it.
Thanks for the ideas. The pruning idea gave me an idea. It may be too thick and crowded. Roundup is another option. Don't plant it because it has covered my red flowering quince that used to bloom every spring with no care. I don't think I could get rid of it if I tried so I'm am trying to enjoy it.

Helen, I live in a house that supposedly was built in the 1970's, but it seems older than that to me. I think there were some buildings here before, and they just kind of worked them into a building. LOL I can visualize someone living here who took everything that someone gave them a start of and just stuck it in the ground, including Honeysuckle, Virginia Creeper (yuck), poke, and sweet peas that climb the fence but offer very little in the way of bloom, and other invasive plants. I made another swipe at it last year and it looks like I got rid of more of it than before. I left honeysuckle in one area, where it has damaged the fence and I can't very well take it out without replacing the fence in that area. Since we are talking of moving that fence anyway, I decided I could endure it for one more year. The trunk of the thing is as big as my arm and has welded itself to the chain link fence. It does smell good, but it was once over a gate and it was a constant pruning job just to keep it cut back so it didn't rub your hair or neck everytime you walked under. Everytime it touches me, I think of ticks. I haven't seen any there, but that is what I think of. It's like walking under a cedar tree....hurry, or they will fall on you. Most of our neighbors have cut their cedar trees, but enough are still around to provide good tick habitat. I had two cedars left until this year and when the contractor for the electric company came to trim the centers out of them, I convinced them that it would save us both a lot of trouble if they just took them down. They agreed. They were both almost on the lot line and near one neighbor's garden. He was so glad to see them go that he rented something and took most of the stumps out. His FIL builds furniture so he hauled off the wood. It all got used or moved and didn't cost a penny. LOL
