Control: out of control
The text in section Control repeats an apparent tale about buckthorn seed longevity. Someone thought to check and seeds only last up to 2 years. See Researchers uproot decades of buckthorn management practices (phys.org). I quite this new era where people check whether oft-repeated facts ever were true. Shenme (talk) 15:20, 27 June 2023 (UTC)
