I have had deer eating everything in sight for many years until I decided to try Liquid Fence. My husband starts spraying in early spring just as the Hostas pop up. He sprays once a week for three weeks and then every three weeks until fall. We have not had any deer, rabbit or wood chuck nibble on my plants since we started this routine. The trick is to keep to the schedule. It seems the second year is better than the first, since we have not seen any deer in our yard this season. The smell is bad for a day or two, but fades. Also, if you buy it in concentrated form, it lasts a long time. It takes my husband about 5 to 10 minutes to spray (in the evening) our yard which is quite large. Hope you give it a try!!!!
