I bought a single, small, bottle of Plantskydd from a locally owned place back in 2013.
That first year either I didn’t apply it right, or the insane rains we had that year reduced its effectiveness, not sure which. But ever since it has worked wonderfully. As long as I re-apply once a month or so it has done an awesome job of keeping deer and rabbits out of my garden.
Did I mention I’m still using that original bottle? Plantskydd’s site says once opened they’re only good for 3 months or so. But if the bottle I have has lost any of its effectiveness I can’t tell. I was slow getting it out on the garden this year, and something was sure munching, but once I sprayed the Plantskydd all munching stopped.
Oh, and I don’t usually spray it ON the garden plants either, though it’s technically safe to do so. I generally just spray it in a circle around the garden and it does just fine!
I will warn you, it REEKS until it dries (which is about a day). Seriously puke worthy reek too. Not an issue where I am, but if you’re gardening in your urban garden and your neighbor’s bedroom window overlooks your garden they may not appreciate you spraying Plantskydd about, just to warn you. The dogs do find it quite interesting though, till it dries, so if you have a dog who’s allowed to run loose by your garden you may want to restrain them till its dry, else your dog may smell extra bad for a while.
Plantskydd isn’t available from any of the big box stores, at least by me. I found it at a locally owned garden place, or you can order it off their website.
note: I bought the Plantskydd with my own money and this review is completely unsolicited, well, by Plantskydd anyway, I had a friend ask me what I used to repel deer!
