I have a small wooden wagon I want to plant small flowers in. Nothing over 12 " tall. They would be in full sun and need to be deer proof, if there is such a thing. I don't want the wood to rot. Thought of using the disposable tin foil pans. Would these heat up the dirt too much and bake them? I live in So Central TX and summer days are often 95 - 100. Would plastic be better?

Thanks Greenceed. I'll quit worrying about it. I seem to kill the most hardy things fairly often. Now to figure out what to plant that the deer won't eat. They even ate my Christmas Cactus one year.
