What gardeners do not understand is that 100,000's or most 100,000,000's of seeds from the weeds that have been growing in their planter beds can last many years, in the case of Malva up to 25 years. It is critically important in keeping control of weeds in large planter beds that a program of killing weeds that are actively growing and continuing suppressing the remain seeds.
