Dear All, eradicating Alocasia.... they need to be pampered here very much..... Northern Germany is not Alocasia Country. We have our weeds, though. What I do when I really want to clear a piece of land is covering it with a solid fabric made of woven narrow plastic strips. It is used in professional nurseries to cover the ground under pots or containers to keep everything weed free. It does exclude light from the ground but lets air and water through. As it is black the soil under this cover becomes quite warm. I mow the land first as low as possible and then lay the fabric and fix it either with pegs or with stones or heavy boards. it needs a season to kill almost everything, the possible survivors can be easily removed. No chemicals, no effort except preparing by mowing and laying the fabric. But it needs time. The fabric can be used many times. It can be walked upon and is sold on large rolls in different width. Bye for today Uli
