Help with bed
I'm wondering if I am doing this right. I am going to have beds that run on the edge of lawn,
I have been digging and am finding lots of tree roots.Some place I can't get the shovel down much more than around 6-7 inches.There is a White Birch tree,another flowering tree,don't know it's name.And several small trees on the edge of the property line.
I plan on amending the soil with about 3 inches of new topsoil,3 inches of compost and 3 inches of this stuff called Barkmull. Which is used as a soil conditioner. I am not going to do anything under the Birch tree as I don't want it to get any ideas!
So even if I can dig down in some spots,will those 9 inches be enough if you add on the 6 that I can get the shovel in?
I also remember seeing someone mention that some hostas cope better with tree roots.Which ones?
I just want some reassurance as I am new to this and want to make the best possible place for my hostas.
Any input would be appreciated.
