For On Gardening I'm Stan DeFreitas, Mr. Green Thumb. We've got the earth box, we've got some soil in it, we've got our screen. We talked about, you know, why that is important. You've got your filler tube over here to the side. You can see that screen is where everything goes through. You see we're using a sterile soil. Now why don't you use your backyard soil? Well, nematodes, fungi, bacteria, weed seeds. That's the reason you don't use your backyard soil. You get a sterile soil. Now we need to put more dirt into this so we're going to add some more soil to this and as we start to add you're going to kind of put it level across the area here, and you of course can put in your seeds, you can put in your little starter plants, but you want to make sure that you've got a soil like this that you can keep kind of adding to it and you want to use the same sterile soil. If you started mixing in some of your backyard sand you're going to have problems. So keep adding into this soil, level the soil out. Kind of play with your soil a little bit and move it around, and as you do you're going to have a near perfect medium. Now you'll notice most of these potting soils are light and there's a term called friable and that just means you've got a nice light soil. If we take this cup up where you can see it you can see this soil is near perfect and that's what you're looking for. For On Gardening, I'm Stan DeFreitas, Mr. Green Thumb.
