Grass Killing #869679

Asked May 22, 2024, 7:06 PM EDT

What can I do to kill grass in my flower beds without killing all other plants in the soil? We have an assortment of plants in flower beds and grass has invaded the beds and is thick as hair on a dogs back. We can't seem to grow grass in the lawn area it grows best in the flower beds where we don't want it. So, what can I spray on the grass to kill it without killing other plants (rugosa roses, wild geraniams, violets, lavendar, etc.)? The grass is way too thick to try and pull out by hand.

Expert Response

Certainly! If you want to remove grass from your garden, there are several effective methods you can consider.


Digging by Hand:


This method involves physically removing the grass using a flat shovel or garden spade. Here is how: Outline the area you want to clear by cutting out the sod in sections (about two to three shovel widths wide and long). Pry up the leading edge of the sod and slice it parallel to the grass, being careful not to take too much soil. Repeat this process until you have cleared the desired area


Smothering with Cardboard or Newspaper:


This is a common method that uses biodegradable materials to smother grass and weeds. Mow down the grass or cut back the weeds to ground level. Cover the plot with layers of cardboard or eight to ten sheets of newspaper, overlapping the edges by at least six inches. Wet the cardboard or newspaper layers thoroughly then cover the layer with mulch. The cardboard or newspaper will break down over time.


Herbicides:


Although not the most eco-friendly option, herbicides can effectively kill grass. Select a product specifically formulated to kill grass. Apply the spray on a calm day and aim only for the grass patches. Make sure to read and follow the manufacturer’s instructions carefully.


Remember to choose the method that best suits your needs and garden conditions. Thak you for your question and happy gardening.
