They attract pollinating insects such as bees and butterflies which use the dandelion as a food source. Some people also eat dandelion. It is important to determine what type of weeds are present in your lawn and garden. Annuals complete their life cycle in one year and produce many seeds. Biennials complete their life cycle in two years - the first year is for vegetative growth, and seed is produced in the second year.
Perennials live the longest of the three - more than two years.
Because they produce seeds from the second year onward, their potential for spread is greater. By identifying weeds, control will be more effective because information on the weed classification, potential damage and management options can be obtained. This information will identify what conditions must be changed and help in determining the appropriate control measures. While this may take extra effort and time, the results will be very pleasing. In addition to creating a healthy lawn, these activities help you achieve a healthy mind and body.
