Gardening experts have unanimously agreed that the most effective method for removing garden weeds is manual pulling, especially after rainfall when the soil is softer. Robert Witcomb, a sustainable gardening expert from eComposite Products, explains that weeds exploit bare soil and disruption, so removal strategies should focus not only on killing weeds but also on preventing their return.
Loren Taylor, owner of Soothing Company, advises pulling weeds by hand after rain to ensure the entire root comes out easily. For deep-rooted weeds, a small garden knife can be used to get under the roots without damaging other plants. Taylor also recommends lightly digging the soil between plants once a week to prevent new weed growth.
After weeding, mulching is crucial to prevent weeds from returning. Organic mulches like shredded bark or wood chips block sunlight, retain moisture, and improve soil health. A layer of mulch five to seven centimetres thick, changed once a year, is recommended. In flower beds, using special fabric underneath the mulch can further inhibit weed growth.
Alternative methods include using vinegar as a natural herbicide, which dries out leaves and destroys plant cells. However, experts caution that vinegar should be sprayed directly onto weeds on a sunny day, avoiding surrounding plants, and not used frequently in vegetable gardens as it can affect soil quality. Chemical weedkillers should be used sparingly due to potential damage to soil biodiversity and surrounding plants.
