I find it quite remarkable that I'm responding to this question, Catherinet. I don't need any checking of authoritative sources to be sure that I don't lead anyone astray. Just my experience and a desire to help . . . Here is my experience with 2 simple gates: One was essentially 4 "panels" since they amounted to a simple movable enclosure to keep the backyard hens in 1 area or another of the lawn. I used 1/2" pvc pipe, 4 elbows, chicken wire & cable ties -- hated those panels! The chicken wire soon sagged, bagged and snagged on my clothing and, at unexpected moments, on my bare skin! (Those panels have been replaced by movable picket fence panels.) The other was an actual gate that was part of a garden fence. I had 2 "allotments" in a community garden - about 15 years ago now. I doubled the gate posts -- so, instead of having 2 posts, I had 4 set closely together so that the gate slid down from the top and was held in place - no hinge. The larger gate posts were part of the fence. The 2 posts behind them were just there to hold the gate and they did a good enuf job to keep dogs and squirrels out, remarkably enuf. Oddly, they were too much for most visitors to figure out. When I invited someone into my gardens, he or she always had to be helped with the gate. It only required lifting to remove it from the opening - and then had to be set aside, leaning usually against the fence. A few 1by2's with chicken netting tacked securely to them. The gate weighed nothing . . . Just my ideas, Catherinet, and it was fun to relive those moments of entering and securing my gardens. Steve

Thanks for jarring my memory. Using the latin name you provided led me to it's common name, Sweet William.

Might I ask if you have a colour preference (to go with your home's trim etc)? Are you seeking low maintenance? Are seeking plants that do well with little water? Once we know what your needs are, we'll be able to offer some helpful plant ideas :) Faye in Nova Scotia

Nice experiment. If it's not too much trouble, can you please update with your process and results? Not sure on this post, but maybe start another one? I've heard about the air layering process before, and always been fascinated by the process. Seems like a cool way to increase plants without the risk of cutting and then hoping for roots to develop.
