Knotweed in denmark says hello :-).
I've been semi-daily (summer months) cleaning a 2×12 m patch of knotweed for 4 years now, on a house we bought.
Currently I have it covered with dark fabric, which I regularly remove to pull up the shoots, then cover again.
They should make an aliens movie about that plant.
- rebuilder 3y agoHow is it going? As I understand it, the plant grows roots several meters deep, survives being covered up potentially for decades and can regrow from tiny fragments of root left in the soil. Yes, I have some I’d like to get rid of, too.
- zarzavat 3y agoHonest question, where does it get the energy and mass? Surely without solar energy, any root system will eventually die. Hell most of the plants that I try to grow suffer that fate despite plentiful sunlight.
- jamiek88 3y agoThe root systems can stretch literally miles.
- veltas 3y agoThe roots go 2 meters deep, and can spread horizontally several meters.
- himinlomax 3y agoHave you tried glyphosate?
- waynesonfire 3y agoI cut the new chutes after about a week of growth and place two drops of glysophate on the stem. Each year I see less and less of them.
- devilbunny 3y agoI'm not a fan of herbicides in general, but I have to admit that direct application of glyphosate in this manner is extraordinarily effective and, if done correctly, poses almost no risk to other nearby plants.
- veltas 3y agoThe amount of effort, I think it would be worth excavating it totally or paying someone to excavate it.
- specialist 3y agoCan you heat treat to kill the knotweed? Like injecting steam into the ground? Inspired by a demo reel of a ground cooking weed remover, I've experimented with using the tea kettle to kill stuff in my drive way. Works pretty good. A few square inches at a time. I poke a few holes and pour in boiling water. The industrial size tool covers the ground with a foam, to create a thermal blanket. And then it cooks the ground. It looks like those street pothole fixing tractors, but using steam, instead of flames to remelt the asphalt. (The foam is like a thick bubble bath and will rinse away.) Just curious. I recently became a "forrest steward" volunteer, and knotweed was specifically called out in training. Do not touch! Immediately escalate! Ignorant, naive me thought blackberry and ivy were the final bosses.
