If a gardener avoids synthetic chemicals, what critical action must be taken during manual removal to prevent the onion grass from regenerating?

Answer

Digging out the entire clump, ensuring every small bulb is extracted from the soil.

Manual removal of onion grass, while labor-intensive, can be effective if executed with precision targeting the underground structures responsible for its persistence. The key lies in the fundamental reproductive unit of the plant: the small, clustered bulbs. If only the visible green foliage is pulled or cut, the underground bulbs remain intact and will sprout new growth. Therefore, the successful strategy for manual eradication requires the gardener to dig deeply and carefully remove the entire clump, making absolutely certain that every single bulb is extracted from the soil. Failure to remove even a few of these separable bulbs will result in the plant’s regeneration.
