Weeds have a large number of mechanisms and characteristics that enable them to survive, many having thick wax type leaves that can be resistant to some herbicides, have fast reproduction methods, the ability to reseed in six weekly cycles and in many cases a more robust root system than any of the common grass species you will see typically in the UK.
Therefore it is important that the correct herbicide is chosen in treating the weed, the correct applicator and nozzles are used or the end result will be that the weed will continue to flourish at the expense of the grass quality. It is important to remember that not all weeds are the same in establishment and growth, having one of three life cycles Annual, Biennial or Perennial.
Live for a single season and these weeds germinate from seeds in the spring or summer, flower and then die.
Live for two seasons. during the first growing season, these weeds remain in a vegetative state and in the following year, produce flowers, set seed and die.
Live for multiple seasons and flower more than once, this is the most common type of growth cycle including dandelion, daisies, plantains and buttercups.
More troublesome weeds where the stems are low-growing, often with short hairs restricting the capacity for the plant to absorb the herbicide, can establish quickly and will have the effect of preventing grass growth. This group of weeds, including speedwell and yarrow, are more difficult to control, and in such instances may require an additional treatment.
