Raised Beds for Vegetables and Flowers

That's right, I am going to be planting this year. Since I do not have the best of luck planting directly into the ground, I am going with raised beds. Doesn't seem too difficult. I have the seeds and am getting ready to sow them. Next I need to find some inexpensive wood to make the beds. Then I need to figure out where to put them, in the front or back. My yards are not fenced in so I am trying to think which would be a better location. I have various veggies to plant and then I am wanting to plant a couple flowers...I will definitely post pictures before, during and after!
