Step 1: Buy black plastic (or collect a lot of newspapers if you’re someone who still reads them… who does that?!)
Step 2: Cover all the weeds so no light gets to them
Step 3: Wait for the weeds to suffocate to death
Step 4: Employ someone to weed for you
So I have this problem with my neighbour’s jasmine vine. It doesn’t understand that I don’t want it here. When we moved in, it had been left to free-range and had gone beyond manageable. We had to take a tree out because it was so overcome. A year on, the ground is a mat of vine and it still keeps coming through the fence. It’s straggling my treasures. I’d lost all hope for the submerged Camelia. But the moment it touched my Japanese Maple it was war. A war I would win. At all costs. Well, at a very specific cost, a per hour cost. But we’re winning.
