Weeds are a constant challenge for gardeners, often cropping up persistently and quickly overtaking garden spaces. Yet, with the right approach, you can eliminate weeds effectively and keep them from coming back.
Robert Witcomb, a sustainable gardening expert at eComposite Products, highlights the importance of a two-step approach: “Weeds thrive in bare soil and disturbed ground, so the best strategy is not just to kill existing weeds but to prevent their regrowth.”
For smaller gardens, manual removal remains a highly effective solution. Robert explains, “Pulling weeds out by the roots after rainfall is ideal because the soil softens, making it easier to remove the entire plant.”

However, extracting weeds alone isn’t enough to stop future growth. Mulching plays a crucial role in long-term weed control. “Mulching suppresses light, retains soil moisture, and enriches soil health over time, creating an environment that’s unfavorable for weeds,” Robert adds.
Loren Taylor, owner of Soothing Company, echoes this advice: “We find hand-pulling weeds most effective after rain when roots come out easily. For deeper-rooted weeds, using a small garden knife helps lift roots without disturbing other plants. We also lightly cultivate soil weekly to prevent new weed seeds from taking hold.”
Loren stresses the importance of mulching after weeding: “Applying a 5 to 7 cm thick layer of mulch—such as shredded bark or wood chips—blocks sunlight to prevent new weed growth and keeps soil moist. In flower beds, we often add special fabric under the mulch for extra protection, refreshing it annually.”
Stephanie Harrod, founder of Harrod Horticultural, concurs that hand removal is key: “Weeds are easiest to remove after rainfall when the soil is loose. Removing the entire root system is critical, especially for perennial weeds, to avoid quick regrowth.”
Beyond manual methods, there are natural alternatives. Erik Collado Vidal, CEO of Growbarato.net and horticultural expert, shares: “Vinegar is a simple, natural herbicide that dries out weed leaves and destroys plant cells. Apply it on sunny days directly to weeds, avoiding nearby plants. Use sparingly in vegetable gardens, as it can affect soil quality.”
Robert Witcomb also advises caution with chemical weedkillers: “While effective, they should be used sparingly to avoid harming beneficial plants and soil biodiversity. Boiling water or vinegar solutions are suitable for hard surfaces like patios or driveways but aren’t recommended for lawns or planted beds due to risk of collateral damage.”
In summary, combining manual weed removal with mulching creates the most effective, sustainable defense against weeds, keeping gardens healthy and flourishing season after season.
