Most other products don't seem to last beyond one light rain or snow, whereas Plantskydd definitely adheres better. Being an urban area with a high rabbit population and a limited food supply here in Omaha, NE, winter chewing damage can be substantial. This winter I've been applying it at the recommended mix ratio about once per month and damage has been dramatically reduced. The only drawbacks to Plantskydd are that the powder can be messy and tough to mix well (mixing in a bucket with a paint mixer in a drill works well for me) and, since Plantskydd contains blood, you have to be careful about over-spray as it will stain. But considering how effective it has been for me, the minor inconveniences of Plantskydd are more than tolerable.
I have been using Plantskydd for many years. I apply it in the fall to my Christmas tree plantation. It keeps the deer away until the following spring when deer are able to find food again. I have experimented with Plantskydd skipping a few trees. The trees that are not sprayed are heavily browsed by the deer. The trees sprayed are left alone. This past fall I did not spray. Several of my trees had the center leader broken by bucks rubbing their antlers on the trees. These trees are now ruined. It pays to spray with Plantskydd. I also think the deer become aware after several seasons that the trees are not a good food source.
I have 5 acres of wooded property that is home to a number of deer. We recently planted a lot of small trees and were really concerned about the damage which might be done by the deer. I sprayed them with plantskydd and was extremely happy with the results. Almost no damage at all. I also tried spraying it on my flower garden to keep the rabbits away and it worked wonderfully well. I would definitely recommend this product.
We are a landscape maintenance company based in Santa Fe, NM, where hungry rabbits vastly outnumber humans. We maintain some 100 properties and are constantly battling rabbits & other animals. There have been many repellents in the crews' arsenal over the years. Before we switched to PlantSkydd this summer, we were faithfully applying a stinky spray, yet still we'd return every week to empty, munched pots and short stems where annuals had once been. We began using PlantSkydd 2 months ago and have not had an issue with the animals since. Another wonderful feature (for our crews and for our clients) is that the product is also not stinky. We are very happy with PlantSkydd.
The product comes in a powder and is really messy when adding water. Despite the mess, I was able to mix up a small quart spray bottle. It worked for about 20 squirts, but the powder didn't mix very well & plugged up my squirt bottle. Had to clean it several times. The next time I used it, I just used a spoon and sprinkled it on my flowers. Unsure as to its effectiveness as I used multiple products, but still had several tulips eaten within a week or two of usage.
