Creating a bed under Pine trees
I'm trying to make a hosta bed in a cluster of Pine trees. I cannot get my shovel more than maybe 1/2 inch in to the ground due to roots. I'm not sure if I'm hitting some small tree roots or if they're all from the leafy weeds that were growing under the trees. Don't know what the weeds are, but their roots are about the size of string licorice and they are pretty tough.
I was thinking I'd clear out the weeds the best I can (I did spray some Round-Up on them yesterday), lay down some cardboard, wet it down well, then start building UP with topsoil.
Can I create a decent planting bed this way? Will it harm the trees if I build soil up around the truck? Or will all the roots just work their way up in to my new topsoil and wreak havoc on my hostas?
Any and all suggestions appreciated!
