This is definitely a weed killer to avoid using on flower beds at all costs.
Combinations
It is also possible to combine the products of different chemical compositions so that you can achieve the best weed control results for your lawn. For instance, if your lawn is grass only, the non-selective type will do its job without killing the grass. If you have flowers, vegetables or decorative plants, a selective weed killer will work best. However, some combination products might not work well with each other. The result would be a decimation of your lawn. You should always be careful with combinations because any weed killer will leave chemical traces in your soil and you do not want to compromise the health of your beautiful lawn in the future.
