This photograph shows the bit of soil where the bindweed continues to attempt to grow despite numerous weedkills and digs over. The roots of the bindweed go very deep and as I understand you have to remove all traces of root and trailers before the area is completely free of this very fast growing weed.
Last year I tried to plant a number of different plants to fill the area but to no avail since the bindweed always took over. I hope that this year I have removed all signs of it and can at last plant something to climb the fence. I am going to try some sweet peas and a clematis hopefully. Watch this space!
