The best time to use weed killer is in the spring and fall. Spring is a good time to catch weeds in their pre-growth season in order to prevent them from growing. The fall is the best time of the year to kill weeds because they are more susceptible to being killed during the winter.

If you are using weed killers in your garden, make sure that they are labeled for use in the Fall and Spring. If you do not know which herbicide is best for your particular situation, you may want to consult a professional.

If you only have a small area that needs treatment, then you can use one or two broad-leaved weed killers, and then apply the other weed killer at the same time.
