I just keep staring at this photo, it's gorgeous!
OK, explain to me how the support is set up here please, I see rebar on the far right and then a pole with what looks like 2 pieces of rebar stuck in it and going opposite directions. Trying to visualize it so I can get hubby to build a few for me, I have so many vines and climbing roses that need some DIY supports!

LOL I can see how this photo is confusing you !
The Austin rose rose is growing on a plain old steel rusted arch/arbor. It's planted on the LEFT side of the arch and grows up and over the arch to the right. (It's hard to see that part of the arch/arbor in the photo.)

There is also a Yellow Lady Banks rose planted right next to Pat Austin...about a foot apart from one another. My ORIGINAL intent was to have the Lady Banks engulf the arbor and Pat Austin hiding what would eventually become the bare legs of Lady Banks. That worked out fine until Lady Banks got so thick that Pat Austin started "climbing" up through it. I found it curious that Pat Austin "climbed" so I just let it go to see what it would do. Realizing that I'd rather have Pat Austin bloom continuously vs. Lady Banks blooming just once a year, I hacked the heck out of LB so Pat could take over.

As is typical with Lady Banks, after I hacked it, it started sending out these huge long whips in BOTH directions. I put an old pipe in the ground about 6 feet away from the original arbor, then added rebar to the center of the pipe and attached the OTHER end of the rebar to the original arbor...thus making a double arbor. Lady Banks now goes up and to the left and the right. There's also a Jackmanii clematis in there that also spans both roses. This was one of those "accidents" that worked out well ! LOL

My garden is only 2500 sq. ft....which is actually considered "big" for here...since these are just small city lots. This is also an apt. bldg....and it's extremely rare for there to be ANY space between the front and back bldgs. This "space" is what makes the garden essentially a "courtyard".

I ran out of room to plant things, so I started putting in arbors. I couldn't go "out" any further, so I went "up". The rose fixation evolved from there. I've exhausted every single square inch of available planting space and have reached the "final frontier" so to speak. I had to leave room for people to come and go from their garages, move furniture in and out, access the laundry rooms, access to the side and rear gates, and not interefere with underground gas lines, electrical lines, sewer lines, etc. The whole space is divided up into little "rooms" (gardens) separated by grass paths. It's as big as it will ever get now. In addition, I can't really do any more with this space because it would create an obstacle to escape in case of a fire, earthquake, etc.

Well it's a sweet little paradise you have created there, I hope the neighbors appreciate it!
Having more space now from what I am used to is great but also overwhelming at the same time but I am slowly expanding and still have lots to plant, over 250 plants still in pots, eventually I will get them in!
Thanks for the detailed description.

Forgot to add this:

Where I am, there are mostly old houses and apts. from the 1920's. Someone is always re-piping a house or apt. bldg. and they leave the old galvanized pipes in the alleys for the recyclers. Those old pipes are ideal for making arbors or trellises or arches. Pound them into the ground, insert rebar and bend it whichever way you like. Then, you can plant some small vine or clematis to cover the bare pipe.

People also toss out the tracks for vertical blinds. Those tracks have a very sturdy aluminum rod inside the track which is equally ideal for the same thing...and even easier to bend and shape. It also doesn't rust or get hot and won't burn the vine or rose, etc. and they virtually disappear in the sunlight.

Great tip, thanks!!
