Hello all,

I have helped out some relatives with gardens before, but this year I decided to create my own small flower garden, Starting from seeds I sowed Sunflowers, morning glories and Zinnia. All appears well until the seedling is a few inches, then they all get munched down! I check frequently throughout the day and never see any insects on them. However, every morning when I go out to my front lawn, they all either appear to be shredded or have holes in them.
Any help would be appreciated!
