“Ready To Use” weed killers, on the other hand, come pre-mixed and don’t require any extra prepping steps. They are as convenient as it gets.

Concentrated herbicides are super potent and need to be diluted with water before use, according to the instructions printed on the packaging.

Rock salt is used as a weed killer in three different ways. Let’s take a look at each method:

Kill Weeds With Boiling Water

Not just any kind!

Liquid weed killer will get into nooks and crannies where your garden hoe can’t reach. You won’t need to lift a single stone to kill the roots underneath.

How to stop weeds from growing in rock beds

Spray stubborn, mature weeds with a non-selective postemergent herbicide such as glufosinate or glyphosate if your rock bed contains no ornamentals. Read the label because some products are best for annual weeds while others are formulated for perennial broadleaf weeds. Reapplication is often required as new plants emerge.

Eliminate weeds with homemade weed sprays. For example, make a spray consisting of 1 ounce of vodka for every 2 cups of water, then add a few drops of liquid dish soap. Spray weeds on a hot, sunny day because the spray isn’t effective in shade. You can also spray weeds with a combination of up to 5 tablespoons of rubbing alcohol in a quart of water.

Spray established weeds with a postemergent herbicide containing sethoxydim, fluazifop, or fusilade if your rock bed contains ornamental plants. Apply the chemical to weeds at the stage of growth indicated on the label. When applied carefully according to label instructions, the products provide partial or temporary control of weeds without harming ornamentals. Reapply as needed as new weeds emerge.

Cultivate the surface of the soil with a hoe to remove top growth. Don’t cultivate deeply because you may bring buried seeds to the surface where they will be happy to sprout.

Less Toxic Weed Removal

Pull weeds by hand, wearing gloves. Grasp the weed near the base of the plant with one hand, then place your fingers firmly on the ground around the plant with the other hand to prevent disturbing the rock bed more than necessary. Water the area first, or pull weeds soon after a rainfall. The long roots are easier to remove from damp soil.

Spray weeds with vinegar, which burns the foliage. For the best control, look for a vinegar containing 10 to 20 percent acetic acid, which is stronger than typical household vinegar at only 5 percent acetic acid. You can also use pickling vinegar, which is 9 percent acidic acid. Be careful not to spray desirable plants.

Dispose of weeds in a sealed garbage can or plastic bag. If weeds are removed manually, you can place them on the compost pile, but only do so if you’ve removed all seedheads ,which should be disposed of in a sealed bag.

Chemical Control of Weeds

A rock bed, whether bedrock planted with succulents and wildflowers or a rock garden, can be an attractive, low maintenance space. No mowing required. However, many types of weeds are persistent and continue to sprout, even in bedrock or in the nooks and crannies between boulders. To get rid of the overgrown weeds in your rock bed, try manual controls or one of several non-toxic methods first because safe techniques may remove established weeds effectively without dangerous chemicals. Resort to herbicides only when nothing else works, and then use a chemical exactly according to the instructions on the label.

Pour boiling water on individual weeds or small areas. Pour slowly to avoid splashing hot water on yourself or desirable plants. Use a stove-top teapot for better control and less risk of spillage while carrying.
