Here's another (h)air-brained idea that occurred to me last fall, but I couldn't pursue it until now. I mentioned in another thread that we had a huge juniper bush by the "inn" and when that was deemed excess and had to come out it left a piece of real estate that I filled with what we call "The Annex". We pushed and tugged a few rocks around to fill it in and started a little "grotto" -type garden that will mature into a pleasant little place just to visit.

We have Clematis climbing up the sunny legs, and several Yarrows around the front. I had thought of wisteria and a few other vines to grow up around the legs to provide a "roof" of sorts, then considered the time involved to have the coverage my mind's eye saw.
Enter the idea...........what if instead of having vines growing up the legs and across the "roof" I built a couple of plumbed in linered mini bogs and had stuff growing across the top and flowing down? A couple of long boxes down each side with some lattice across the "rafters" to support the growth. I'm thinking it shouldn't take too long to see some results. Full sun, pond water, and although not large they should prove to be a benefit.
Here's a few photos of where the project is this afternoon. I'll detail the plumbing and continued construction in a subsequent post.

The boxes/troughs will sit on cleats fastened to the inside

First box test-fit on the cleats. The boxes are a slide fit and shouldn't sag because of the side fasteners. The cleats won't move because the "rafters" are notched and won't allow the header to move outward. There will be trim pieces to cover the exposed fasteners.

I have the supply line figured out for the back side of the structure (accessible, but not visually obtrusive) with valves dedicated to each box so the flow (the pump is rated at a thirteen foot head. We're at eight feet,) can be controlled and not over come the return..........
.......here's hoping anyway.:)

NO WISTERIA!!!!!!!!!!

I think we kinda had this conversation a while ago :) My land is infested with wisteria and killed all my big trees. ONLY native wisteria is a safe choice to plant. Dont by Asian wisteria. You know by their time of blooming. Invasive wisteria blooms very early (blooming a few weeks ago and still blooming now)

Soon when i have time i'll go out with a chain saw and cut them all up. but with 100s little vines and 100s big ones per tree it's going to be a big big job.

ok, that's out of my system :)

I have the same pergola! that's a great idea i'll have to see if my husband will agree to something like this :)

Thank you all for the comments and interest!

Nepen, the "no Wisteria" was one of the reasons I pursued this avenue. I wanted something that would accomplish the goal quicker without being a problem later on. Whatever I put in these "Sky Bogs" will have to behave because they'll be totally contained and dependent on the water provided. "Bad actors will be severely dealt with...":)

I'm open to suggestions as to what should go in these boxes. The criteria being; fast growing, preferably large leaves, full sun, but ample watering available. Flowering would be a plus, and I won't mind an annual culling. They will freeze in the winter, probably to a low of 0 degrees because although they may be damp, I don't want to have them full of water to freeze, expand, and potentially break/spring the box.
We will have Clematis on the corners eventually, so they'll provide a little texture.

I think there's a vine type hibiscus? that'd be my vote.

Any Native plants, like yellow Honeysuckle, Clematis viorna, native climbing Hydrangea, American Bittersweet, Purple Passionflower, Salal...

Very cool! I would also love to watch it progress! I love bogs of any kind because they provide plants that I don't have the water :)

purple passion flower is just as bad I planted one little vine and have to clear it out from every where it is now even sending up sprouts under the front porch and also found it growing under the back deck when I put new boards down .I like clematis vines they are easier to control

This is just the inspiration I needed to put some odd salvaged wooden troughs to good use! Not a sky bog, but as shallow planters around the base of my raised metal trough pond, with hidden drip lines from the pond into the troughs. Hoping whatever I plant in the low troughs will enjoy full sun and help shade the metal pond.

Glad to help!:)
The only thing I would add is the troughs I'm building will have pond liner in them so the even though the wood I'm using is pressure treated, it won't be permanently saturated.

Agreed! A little work now so I can be a slacker during the summer!(y)

....................... if this works.................................
Right there is the whole thing! :)

Installed the liner and added the trim pieces to the troughs.

Slow progress, but perhaps a couple items of interest......
Each trough weighs 38 lbs with trim and EPDM liner. I rounded up to 40 pounds.That translates to 20 pounds per cleat so far. Excellent.
DSC02244.JPG DSC02245.JPG

With a little more figuring I came up with the following: (round figures)
Inside dimensions, 7"X 7"X 66" = 3234 ci. A gallon of water is approx 231 ci so, 3234 divided by 231 = 14 gallons. A gallon of water is 8.32 lbs. thus 14 X 8.32 = 116.48 lbs. (116.5).
Adding the water weight to the box weight we get 116.5 + 40 = 156.5 lbs. This comes up to 78 lbs per cleat. Still well within reasonable limits.
What I don't know yet, is what 5" of pea gravel will weigh, but am confident an entire trough mounted and loaded will be under 200 lbs.
I think the installed cleats would be adequate, but for added insurance (and peace of mind,) I'll add another cleat to the box on the area exposed above the header that will rest on the upper header edge. (Last photo in the original post. I'll add another photo to clarify this.) With this addition the Sky Bogs will be supported in two places on each end....should be plenty.

Here's another update.
Added the additional cleat, got the bogs water tested and mounted today. The extra cleat is very subtle and I don't think distracts from the appearance at all. Once I got the troughs up I suspended myself from the middle of each and bounced around a little. There was no sign of any movement at all, and I exceed the 200 lb target.:)
This is the "safety" cleat;
DSC02254.JPG DSC02255.JPG
It rests on top of the header on the outside.
Have also roughed-in some of the supply plumbing. The hose will provide pond water from a submerged pump. It will be supported by clamps to prevent any undue stress on the shut-off valve. Each trough will have a ball valve to regulate the volume of flow and will also serve to isolate each one. These will also prevent siphoning water out in the event the main shut-off valve fails or a leak develops. When the pump isn't working the gate valve will be closed or the bogs will certainly siphon out. I prefer not to use vacuum breaks only because the siphon is actually the way I will empty the water in the troughs if it becomes necessary. The pipes will go over the rear ends of the bogs and from there a short piece of rubber hose will be attached to a short nipple then back to plastic pipe with holes drilled in it the under the gravel. The rubber hose is to provide a break-point to allow the system to be opened.
DSC02261.JPG DSC02259.JPG
All of the pipe will be painted with a plastic specific paint to blend in.
From a short distance the "Sky Bogs" are hardly noticeable and unless pointed out, I doubt anyone would really notice.
DSC02256.JPG
One caveat: If I were to do this again, (and I may do it this time to one trough in the name of "science":)) I think I would coat the inside of the bogs with epoxy. I'm very tempted to do one now leaving the other lined with EPDM just to see if there is any appreciable difference in performance or longevity. Obviously the EPDM can expand and contract in different weather conditions, where the epoxy is somewhat less forgiving without the fiberglass reinforcement.
The real advantage to these bogs are if there is a problem, or if a leak develops it would be very evident and they are easily removed, (may have to unload the gravel, but that's easier than draining a pond...) repaired and replaced as neither one is fastened, they just sit there.
Now I have to bury the supply hose and develop the returns. I think "She who must be obeyed" has some domestic items I have to attend to before I can return to these important matters!:D
