Our landscape is all outside the screen enclosure and apparently includes a couple bits of deer candy. Every few months they come through and strip several sections of all leaves. It was worse in the winter and at this point everything has (mostly) recovered and pushed new growth. I just picked up a bottle of Ortho "Deer B Gon" and sprayed down the tasty plants. From the smell I've gotta think it is a clove oil of some kind?
It says to spray monthly... so at $10 bottle it's affordable. But if I could just boil up a handful of cloves it would be cheaper? I'll see if this works first... but in any case. What do you all use to repel deer?
