I have tuned over some of my lawn about 4 metres south from a mature Sycamore tree to create a raised bed to grow veg. The bed is about 3 metres square and gets full sun all day.
The problem is that despite frequent digging over, the bed is plagued with fibrous roots ( they must be from the sycamore) which take all the moisture from the soil, despite my adding bags full of compost and horse manure each autumn for the last 3 years, the dry conditions restrict the veg growth.
I am considering removing all the soil from the bed and laying a membrane on the bottom of the bed to prevent the roots spreading up to affect my veg.
1. Do you think it is worth doing?
2. Do you have any other ideas to combat the tree roots ?
I am desperate!
