This year I bought a plant tray with 6 plants at the garden center. I planted them the 1 day of June after 4 months of none stop rain every day. Plants did not seem to grow at all for about 3 weeks then all of a sudden they took off growing. I have been turning the runners around making them grow back across the potato bed but now there are so many runners I can't keep up. I have been turning them around every day but the next day there are another 60 runners to turn around again. It is a full time job keeping them turned. It looks like these things are going to take over the whole garden.
