We have been regularly spraying all of our plants with Liquid Fence. Any other year, the Liquid Fence always did the trick--the rabbits never even looked twice at my petunias. But not this year... so we doubled down and came up with a solution. Here's the recipe Ange experimented with, and so far it seems to be working. The rabbits have not bothered our latest batch of Waves, the new patches of seeded dirt are coming up, plus there are fewer rabbits lurking in our yard.
1/8 cup Crystal Hot Sauce
1 Tablespoon Cayenne Pepper
1 Tablespoon Powered Onion
Enough hot water to fill up a 1 quart sprayer
Boil the above mixture on the stove until the cayenne pepper dissolves, but make sure you strain it with a cotton cloth to remove the remaining cayenne pepper particles, otherwise it will clog up the sprayer. And remember, be especially vigilant with your applications.
