Glyphosate is a non-selective herbicide and kills most plants when a sufficient amount is applied to the green and growing surfaces of the plants. It works by interrupting the plant's ability to produce energy for growth and survival. Glyphosate easily dissolves in water and is sold as a dissolving powder or salt, concentrated liquid or premixed.
Flower Bed Preparation
Because glyphosate becomes inert when it binds to the soil, it only kills plants that have contact with the spray containing glyphosate. What this means is that glyphosate can be used to kill all vegetation in a proposed planting area, without long-term effects. New plants can be planted in the area where the glyphosate was applied within a period of about two weeks.
Orchards and Trees
Glyphosate is often used around woody plants such as trees and shrubs. This makes weed control of forested areas and orchards much easier and less expensive than using manual or mechanical means to remove weeds. However, care must be taken not to spray the suckers, or green growth, growing from the roots of some trees, or lower limbs of the trees, because once the leaves have contact with the glyphosate, the entire tree is affected and may die.
Driveways and Walkways
Glyphosate can be used to control weeds and grasses along and in driveways, sidewalks, paths and walkways. Application frequency depends on the type of weed and grass you are controlling.
Everyday Weed Control
Glyphosate is used to control weeds in everyday situations such as around lawn furniture, decks, patios, fences and other permanent yard fixtures. It can also be used as a spot treatment in flower beds. A spot treatment means only the target plant is sprayed, rather than broadcasting the herbicide over a broad area. Care must be taken to avoid accidentally spraying desirable plants with glyphosate.
