Wild Chervil Removal Tips
Should you wish to rid yourself or others of invasive Wild Chervil, a Naturally Curious reader, Susan Hand, generously shared this helpful information:
Wild chervil is not a strict biennial but monocarpic meaning that it flowers once then dies. The problem is that each root is capable of producing many offsets, lateral buds that do not die when the main root dies. New seedlings can take several years to reach blooming size.
The best way I have found to control or remove this plant is to dig it up being careful to get all the buds. The roots tend to be less than one foot deep but you do not need to get all of the root just the very top where the leaves join and the root and all the offsets, think carrot not dandelion.
I live in central Vermont and have been dealing with chervil for 19 years removing it from my 3.5 acre property and have for the most part succeeded. I have found if I remove all the blooming plants and as many of the smaller non blooming plants that I find the it does not spread but it can take up to five years to completely remove a large patch.
