Karibu bila ubaguzi, akalala `atakuwa (kuharibiwa, dhaifu) eneo mara kwa mara anaanza hadi umbali wa sm angalau 20-30 kutoka Them. Hata katika mashamba, Hiyo akalala `atakuwa (kuharibiwa, dhaifu) karibu kabisa - Ingawa inawezekana, Hiyo mimea karibu na margin pewa sehemu juu ya nishati. Inawezekana, Hiyo mimea karibu na tramlines (kitu kukua huko), zaidi inaweza kwa urahisi kujikwamua Kemikali Hatari Kwamba, "kuondokana na hivyo", na kupona haraka.
