Because of reports of it's long lasting effectiveness I decided to give Plantskyd a try. Problem is, I couldn't adequately dissolve the stuff to stop it from clogging my sprayer.
I ended up double straining it after shaking up quarts (cup of PS to quart of water) in a 2.5 gallon jug. When I left the dredges in the container it worked OK but that's way too much hassle for me. Might as well just buy powdered blood and add a sticker. I used to think Surround was a hassle but this stuff leaves chunks no matter how I tried to mix it.
Actually I used to hang small bottles of powdered blood mixed with water throughout my nursery. The problem was when you accidentally bump into it and get the fermented stuff on you. I had good luck with it as far as repelling deer and if you set it up so rain can't get in it will last the season.
