If Roundup Is Sprayed Around Lavender Could That Stop It…
Vicki Asked
If Roundup is sprayed around lavender could that stop it from blooming?
It was so beautiful and it looks like it is dying. I personally despise RoundUp but my husband frequently sprays it when I’m not watching.
The Gardener’s Answer
Hello, Vicki: Not only will RoundUp stop your lavender from flowering it can actually kill your plant. RoundUp is a nonselective herbicide and will damage or potentially kill any plant it comes into contact with. I am sure your husband has good intentions and is killing the weeds in your garden, but even spot spraying with this product on a windy day can be dangerous. The active ingredient in RoundUp is glyphosate. When it comes into contact with the foliage of any plant material it is absorbed and eventually works through the plants tissues, which in turn stops the metabolic process essential for plant growth. It can take up to a week for damage to be seen. Typically the plant begins to wilt, turn yellow/brown, and eventually dies. The glyphosate is absorbed all the way through the root system of the plant, giving it no chance of survival. This product does not work its way through the soil, it has to come into contact with the foliage, which is why it is so important to be very careful when spraying around plant material that is not intended to be sprayed. Using a shield like a piece of cardboard when spraying will help protect your garden while getting rid of the weeds.
