I am planning to plants red robins along the side of my house where i've dug up. Is there any tips to prevent unwanted weed and things growing with it? The red robins I am getting come in small plant containers. So I assume I just dig out a little hole for each one and then put the red robin in and then pack it with soil? shall i put wood bark or stones on top? Do you need to water it immediately after planting it?
