Plantskydd deer and rabbit repellent uses the off-putting scent of bloodmeal to drive away some of the most relentless garden pests. The Plantskydd formula is all natural, and bloodmeal is EPA-approved as an environmentally safe ingredient. It has also long been used as a high nitrogen fertilizer for many plants--in fact, you can use Plantskydd as a foliar fertilizer while you are protecting them from damage. Plantskydd is also remarkably long-lasting. It will remain active for as many as 6 months during the winter, and up to 4 months during the growing season. After 24 hours, it will be completely rain fast. This package contains 2.2 pounds of powder concentrate. It yields 10 quarts of ready-to-spray repellent. This package contains enough repellent to treat 900 plants or seedlings about 1-foot high.
