Well, there is no other place to plant the Peashooters. And there is nothing else to to do than to perk them. I suggest putting the Peashooters in upper spots first as those will reach a fair space when perked. Best boosts are Lawn Mower and Zombie Zapper per usual. Actually I can't really think of any suggestion besides what you already know. Perhaps try differently every time until something works out.
