now you will want to make sure that it is sitting level with the edge of the cup. so i will lift it up a little bit and put dirt down under the seedling to get it sitting at the right height once it is siting at the right height fill the rest of the cup with dirt dont put too much then you will compact this a little bit. after you have the seedling at the depth that you want you are going to want to really soak this. soak this till you see water coming out of the bottom.
