5 Common Approaches
Mulch doesn’t necessarily kill weeds directly it is more of a preventive technique. Mulch works as a protective barrier to block the sun from any weed seeds that may be hiding in the soil. When done correctly, you will save precious garden time which you can then spend on nurturing your plants. Be sure to remove any existing weeds before adding your mulch as smothering them won’t work, they will grow through it. Mulch comes in a few different forms...
It’s important to avoid layering mulch too high, about 8cm is fine, too much height will invite slugs and rodents. Mulch done right will both retain moisture in your soil while breaking down and enriching it at the same time.
As a fast resulting weed control method, vinegar affordable and natural as it is usually derived from the grain, apples or grapes that are distilled through fermentation. It contains acetic acid which is what makes it so effective.
Mix 3 litres of white vinegar with ¾ cup of salt and 1 tablespoon of dishwashing soap (this works to adhere the vinegar and salt to weeds more efficiently). Once mixed thoroughly, funnel the concoction into a spray bottle. Apply to your weeds on a dry, sunny day. Over the next couple of days you’ll notice them die off. Be careful where you spray as vinegar will kill everything it touches.
Boiling water is extremely effective at killing weeds. Poured straight from the kettle and onto the weed will scald them instantly. This may take a couple of tries, but eventually the weed will stop returning.
