My neighbour cut down the leylandii on our border last autumn, leaving the stump. How long will it be before i can successfully grow flowers and shrubs in the soil on my side of the stump? Thanks
If at all possible, you will want to remove as much of the stump and roots as possible. This will make your soil usable much faster. You will want to condition the soil by digging in dolomitic lime, and good organic material. Otherwise, it could take a year or tw for it to degrade far enough to plant around.
