Help please to stop ground covering plant spreading.
My wife and I recently moved into 1930`s house, I noticed a profussion of small ground covering plants with small green leaves with orange flowers in the border as I dug out some old rose bushes. As I lifted these small plants I noticed they have tubers like a bunch of grapes. That was during the summer and now the plants are back, they are spreading again in the border and are now appearing in the second and third row of paving bricks on my patio as well.
Help please to get rid of this nuisance.
