Brilliant! I do have one question--how do YOU get into the garden?
There is a terrible deer problem in a "gated community" near us (the residents feed the deer)and I'd like to pass this idea along to them. However, they aren't too inventive, so I need to tell them how to access their gardens.

I had the same concern just before I erected the fence. I just lift the bottom two strands over my head when I enter the garden. I do this for my push mower also. The fishing line is very stretchy and I don't have any problem with it. Just don't make it guitar string tight when you put it up. I suppose you could also untie one end at a post and enter the garden that way.

I will add to my original post. The reason the deer won't "cross the line", so to speak, is they can't see the fishing line and are frightened off when they touch something they can't see. It truly works.

i like the idea and may try it around the trees planted around the garden...have not had a HUGE problem- YET, though recently found a pile of deer crap nearby ( it ate the flowers but left the veggies alone)

I'm using yellow baling twine, and it seems to be working. I would've used clear monofilament line, but all I had was twine. Except there's a baby deer that's about a foot and a half tall, that walks under the bottom line. I started mine at 18" off the ground, so I need to put one lower like you have. I'm going to put up a fence after I get everything planted though, since I need to keep out more than just the deer. And I think the deer may be a little more motivated to go through the lines, once everything starts ripening.

We have a deer fence around a large area, and inside it, around a smaller area (the veg.garden), an electric fence. Those two fences keep out all but, chipmunks, woodchucks, squirrels. In the veg.garden, we now have a radio playing music/talk/whatever 24/7 in the hope that the sound will scare away the critters. (Neighbors are far away and can't hear nor see.)

To keep out deer, the fence has to be tied to the ground (we use re-bars to weigh the fencing down). Deer will crawl under the fence if given a chance.

Also, most of the time, black fencing material works ok, except when hunters are around, when some deer will crash through the fence (because they can't see the black fence against dark, shaded areas?) We left the black fence up and added on to it a white trellis net (6-inch openings) that we got at Johnny's. It's called Trellinet or Hortonova, 78 inches wide, or thereabout.

We used 10-foot-long re-bars for poles, and electric ties for tying the netting onto the re-bars. Straps need replacing annually or biannually due to sun.

To pound the re-bars into the ground, we made a pounder from a three-foot section of 3-inch black pipe, threated in one end. To close pipe in one end, screw on an end cap. It's an excellent tool that I couldn't do without. Pounders go for 40 bucks or more, but the 3-inch pipe w/end cap can be had for a fraction. Got it all at HD some years ago.

Good luck with your fencing. Life is so much less stressful w/o deer and other critters destroying our garden.

PS when choosing fencing materials for a deer fence, choose a material that'll keep out rabbits, racoons, and all the others as well (if that'll ever be possible). Woodchucks dig tunnels and are very difficult to keep out. They need radios to keep a respectful distance.
