Natalie - I agree: no fencing = no flowers. Tonight I draped a piece of the large type deer mesh over an area just because there are lilies and phlox and they don't even look interesting when the deer attack them. I'd go with Ortho's Poison Ivy and Tough Brush Killer, which works so fast. It's almost instant gratification (but only as a last resort).
Good idea, Chelle. A few pieces of rebar can lift the deer mesh high enough to allow Natalie access but keep the deer out. There are cables of various lengths to secure the netting to the rebar. Here they're sold in the electrical department of Home Depot.
I have sufficient nightmares, complete with blood curdling screams, and can't imagine what they'd be like if I encountered a snake while gardening, Karen!
