Frequently Asked Questions
Will one application kill Bermuda grass permanently?
It is very rare for a single dose to finish the job. Because Bermuda grass grows from an extensive underground network of rhizomes and stolons, you usually need a follow-up treatment. Plan on applying the product two or three times spaced a few weeks apart. This approach catches any new shoots that emerge after the initial treatment has faded.
Can I use these products on my vegetable garden?
Most herbicides are not labeled for use around food crops. If you spray near your vegetables, the chemicals can be absorbed by the roots or drift onto the leaves, which makes the produce unsafe to eat. If Bermuda grass has invaded your vegetable patch, your best bet is manual removal or using a physical barrier like landscape fabric. Keep the chemicals in the lawn or flower beds where they belong.
Why does the Bermuda grass turn brown but then come back?
That is the nature of a resilient weed. The herbicide likely killed the green blades above the surface, but the root system remained alive and strong enough to push out new growth. You must be patient and diligent with your re-application schedule. If you stop after the first sign of browning, you are essentially just giving the weed a brief haircut.
What is the best time of day to spray?
Mid-morning is ideal for most applications. You want the dew to have evaporated, but you should avoid the intense heat of midday when the plant might be wilting or closing its pores to conserve moisture. Applying in the morning ensures the plant is actively photosynthesizing, which helps the herbicide move rapidly down into the roots. Calm, windless days are essential to keep the product exactly where you point the nozzle.
Does Bermuda grass herbicide kill other types of grass?
It depends entirely on the chemical composition. A non-selective herbicide like glyphosate will kill absolutely everything, including your desirable lawn grasses like Kentucky Bluegrass or St. Augustine. If you are trying to save your lawn while removing Bermuda grass, look for a selective herbicide that lists your specific lawn type as safe. Always double-check the label for a list of grasses that the product is known to damage.
