Well, the main places that wild blackberries wouldn't be organic would be near a road (because of vehicle exhaust) or near agricultural land where herbicides or pesticides might be sprayed. Maile ta testo thaunko khanu hudaina bhanera obviously sabailai thaaha hola bhanera detail ma lekhina. Anyway, thank you for the correction!
I couldn't understand what you meant by "some berries look exactly like berries." Ma basne yo saano city ma blackberries nikai invasive chha. Mero bichaarma edible blackberries sajilai chinna sakinchha. Maile aru berries like strawberries, blueberries, raspberries sakesamma yehako local farm bata kinchhu.
