Apply spray repellents like Deer Solution
, an odor-based, systemic repellent, every three to four weeks once plants have fully leafed out. Spritz flower buds as they appear with an egg-based product like Deer-Off
; systemic products are not taken up by flower buds. Deer-Stopper
is a good alternative, or you can make your own repellent; mix and spray the following ingredients every 10 days: 1 egg, 1/2 cup of whole milk, 1 tablespoon of cooking oil, 1 tablespoon of liquid soap, and 1 gallon of water.
