Chithandizo pa siteji iliyonse kukhala operewera, monga kupewa nthawi zonse kumabungwewa.

Popewa matenda pa zomera , zomera ayenera kukhala nthawi 4 pa nyengo njira madzi a anati mankhwala, sitimadzipereka mu chiŵerengero cha magalamu 7 ufa malita 2 madzi. 500 ml ya njira ankafunika kwa mbewu iliyonse kutsanulira.
