Contact weed killers are great for eradicating common annual weeds like nettle, crabgrass, bindweed, mallow, and others alike.
Which type of herbicide you choose depends on the type of weed you have growing in your rock bed, annuals or perennials?
Contact Vs. Systemic
Turns out, you don’t have to spend loads of money on the best weed killer for rocks either . You can simply use some of the staple pantry items that you already have at home. Let’s take a look.
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.
Organic Or Non-Organic?
To increase the effects, you can heat the vinegar prior to use and let the temperature do its work. You can also try using horticultural vinegar with 10% or 20% acetic acid for quicker results.
Household white vinegar will also kill some weeds, although it is not very powerful. A better solution might be to buy horticultural vinegar, which is available online or at a home improvement store.
What To Do Before Laying
Landscape fabric does not stop weeds from growing forever. Weed protection usually lasts a few years. Then organic material starts to build up between the rocks, weed seeds are carried in by the wind, and weeds grow again. Sometimes these new weeds can be hard to get rid of because their roots get tangled up in the fabric.
You could leave holes in the plastic around your bushes to let the air and water in.
