Plants Vs Zombies ACHIEVEMENT Help!

Hello guys!

A very simple question here.

How do I beat the "Good Morning" achievement in the game? I have everything else completed save for this achievement, and it is really buggy the **** out of me.

Please, please, please help me! Thank you!

Hiint help

I have same problem. At first used daisies and that was no problem, but when I didn't get credit i realized daisies were not allowed. Even with two coffee beans I can't get them activated often enough to help. What am I missing?
