Has anybody else noticed they are really thick this year?

Not so bad here; prolonged snow cover and a very, very wet May (when
the first little bunnies should be coming).

The ones in my
yard are very brave as they will lay right where they are until I get right
up on them. They have eaten just about every leaf off my sunflowers (about
2' high). Can anybody tell me, will these sunflowers continue to grow or do
they die off after they've been chewed on by the rabbits?

If they've grown beyond the rabbits reach, and the rabbits aren't desperate
or clever enough to chew through the stems to knock them over, they might
continue growing. But they won't be as robust as ones that had never been
stripped.

You will sometimes see circles of chicken wire in my yard to ward off rabbits
that have taken a liking to some of my plants. (The veggie garden is fenced.)
For non-edibles, Ro-Pel spray will also work, but needs to be repeated after a
good rain.
