Digging new beds.
I am trying to dig out new beds in our garden. I am digging them where we have had Leylandi cut down, stumps ground out and I have also removed lots of Ivy. There has so far been a massive amounts of roots, some huge, some fiberous and some that when you start to pull you get about 6' of long thin root. I,m assuming these are from the leylandi and the ivy and what I,m looking for is some confirmation from you lovely experienced people that by digging these beds out removing what roots I can that I shouldn't have to many problems with stuff, or even trees !!!, growing back. Also is there anything else I can do to try to ensure success !!
Thanks in anticipation
