All design work must be refined with repetition. Less is most always more. Better materials can be found and used, those more compatible with their function. These are good choices for the planet, and help keep that money in your vacation fund.
I must say that it is amazing how little boundary one must construct to keep a deer from eating your bushes. They seem not to need a whole lot of suggestion. Tree-pees have solved the deer problem for me for years, even with bushes fairly enveloping the support.
This tree-pee is three or four years old. The snowball bush and the tree-pee have a sympathetic relationship. They are one! There is nandina, lilies: ginger and not, and a couple of other things planted in the space of the circle that the bush does not use. Interestingly, every fall a couple of the snowballs bloom. But in the fall, they are flat like little discs, rather than exhibiting their Seuss-like splendor in the spring. You can see two blooms above.
At the farm down my running route, they simply put a small plastic ribbon on a wire about four feet off the ground and maybe every six to eight feet down the line. That does it for a whole field planted with something deer love. Amazing.
I use cedar from our woods as much as possible as that wood will last longer than any other around here. The jagged protrusions I cannot help but think serve my purpose as well.
This tree-pee rests on the side of the woods and protects an oak leaf hydrangea. This was propagated by me, one of about 12 starts. Only this one survived, and with the way the deer love this plant, I am interested in defending only one.
This pyracantha is well protected by this heavy tree-pee. The bush is doing all it can to attract bad visitors, but all that showiness is unsuccessful. A Japanese climbing fern asserts itself on the rightmost piece of cedar. There are also day lilies in this bed, and all to the left are tiny iris, purple; I call them Japanese, but that name is wrong. They are however the iris one sees on Japanese byobu.
So here is the new reduced-in-design tree-pee. Again it houses a pyracantha, one propagated by me. It was tiny when it was planted; I fairly crocheted a little string net around it. And as it grew, bigger uprights were piled around it, and when my cat knocked the whole thing down last week, it had needed to go for months.
So what is different here? Had my best idea in a year when looking for three uprights. Seeing one of the awful woods vines we have here that grow to a hundred feet and compete with almost any kind of tree, I realized that the cut vine would be flexible and would simply wind around the uprights, and wherever it crossed, it could be tied. Simple. And that is just what I did. The tension created by the winding of that almost-live thing is quite extraordinary. And the spiral extends beyond the uprights according to its own will.
Then the vine ended. It was too short for the whole job. Could not find another because a rampage was conducted (by me) last spring cutting all those vines in the front woods, and a fire ensued which provided much satisfaction. So a very young tree, growing too close to another was clipped and it worked in the very same way!
