Around here a single strand of electric fence~ about knee high to an average man~ works just fine. Deer are curious by nature and they also like to gauge what they are to jump over, so they take a sniff...ZAP! They won't cross over it or get near it again. Has worked 100% of the time for us and we are in deer central. No need to bait the wire or place anything on it so they can "see" it...just the single strand, about 2-2 and a half feet off the ground.
Used that method to keep deer out of the garden for 30+yrs around here. Now I've got a Jake, so no need for it.
I love hot wire...that's my preferred method at home too. I'm preparing to put some up in the front by a couple of new fruit trees that the deer have been eating. I also want to put dh's trail camera out there so I can enjoy the satisfaction of seeing them get zapped.
Deer netting is OK but a pain to put on and get off later in the season (after the plants have grown through it). I've successfully used it on posts around my garden but after a few years the weather (particularly snow and ice) takes a toll.
I've heard of folks stringing a run of monofilament fishing line around the perimeter of their garden/orchard - the deer don't like touching something they can't see (and can't figure out if/where there are other lines) - but haven't used that because I also have rabbits and groundhogs to deal with. Anyone actually tried this? It would be inexpensive it if works.
An electric wire others have recommended is a more permanent and effective solution for a large area. If you have an outlet nearby the setup is simple; if not, there are solar powered units that charge up each day and have a battery to work through the night. Good luck!
Yep new fruit trees, what amazes me is deer selection how do they know which are the most expensive trees? Had a $10 apple tree next to a $70 pear tree, guess which was dinner! Also picked up miliogrite (sp) man at nursery said to fill netted bags with it and hang from trees.
Milorganite? Treated sewage waste used a fertilizer for lawns and golf courses that's made in Milwaukee, Wisconsin? It is a bit stinky, but I've never heard that it keeps deer away before. You'd have to use some fine netting to keep the tiny bits inside the bags. On the other hand, I purchased some for pollinating from a site I found on line (and can't find link to right now).
