FREEZE OUT WEEDS

Sunday Tasmanian - Tassie Living - - HOME -

HEAVY win­ter frosts can be used to im­prove and lighten heavy soils. Roughly dig the ground to leave the soil in large, ex­posed clods. Dur­ing ex­tra- cold nights they freeze solid, then thaw dur­ing the day. This al­ter­nate freez­ing and thaw­ing makes clay soils more fri­able while also killing peren­nial weed roots.
