How to Add No-Suds Soap to Herbicides
Herbicide comes in two different types: pre-emergent and post-emergent. Add soap to post-emergent herbicide to aid in attaching the chemicals to the plant and drying the weeds out. Soap can also be used as an insecticide. Pests such as mealybugs, spider mites and aphids can be controlled by spraying them with soap. When these insects are sprayed, their cell membranes become disrupted and dry out. By using a non-suds soap, you make controlling the spray of the herbicide easier. Does this Spark an idea?

Tips & Warnings
Dig a few feet around seedlings and lift up any weeds from underneath. Seedlings are very susceptible to weeds and herbicides, so you should not spray anywhere near the young plants.
Avoid using the herbicide on grass weeds. The chemicals will sink in the ground and kill surrounding grass.
