Advice on how to kill onion weed

Onion weed is a very invasive plant that can take over your garden, smothering other plants if you do not control it. It is very persistent and can take considerable time and effort to get rid of it completely. It spreads easily due to its many bulbs which can fall off, leading to the appearance of new plants. Thanks to this, manually removing the plant is not an effective way to kill onion weed because several bulbs will remain in the soil.
