In recent years, many gardeners have relaxed their approach to weed control. Natural gardens, wild patches and meadow-like planting have ushered in a more carefree approach to weeding. This positive change is rooted in environmentalism, with an awareness that we, as gardeners, have a part to play in caring for the soil, the wider ecosystem and the wildlife where we live.

However, as a gardener myself, I know that there are certain weeds you do not want growing in your flower beds or vegetable garden. While using inorganic chemicals to remove weeds is not recommended, there are effective methods that can help you clear nettles, brambles and dandelions, and fall is a good time to get organized and on top of your weeding for next year.

So, if you are wondering how to kill weeds in the fall, our guide has all the information you need for targeting problem plants before they settle in for the winter months and return in the spring. Here, I share tips and tricks for clearing perennial and annual weeds, and lessons I have learned from working in private and public gardens across the UK.

How to kill weeds in the fall

When it comes to weed removal, using natural methods is much preferred over chemicals. Whether you’re dealing with chickweed in your borders or clover in your pathways, there are weed control techniques that are particularly effective during the fall months without impacting your wildlife garden. Get a head start on weeding for the next year by following our simple guide on how to tackle weeds in the fall.

Manually removing weeds

Manually removing weeds, though time-consuming, is one of the most effective ways to get rid of unwanted plants in your garden. Many gardeners find this traditional approach to weed control to be the most mindful. Spending 15 minutes a day hand weeding in your yard can help you get some fresh air and vitamin D during the fall.

During the fall months, mild temperatures and plenty of rain create ideal conditions for rapid germination of annual weeds. Young seedlings will start to emerge across beds and borders in October and November. A garden hoe can be useful for annual weeds with shallow root systems like henbit, deadnettle, and chickweed. Loosen the soil with a hoe and then pick out the weeds. Be careful not to remove any desirable seedlings like foxglove or aquilegia.

Dealing with perennial weeds like nettles, brambles, and dandelions requires more precision and care. These weeds have extensive root systems or rhizomes that must be completely removed to eradicate them. Nettles, for example, have rhizomes that grow horizontally, creating a network that allows them to pop up in various locations. Brambles, plantain, dock leaf, and dandelion plants have deep tap roots, making them challenging to eliminate. Patience and care are key.

For larger clumps of perennial weeds, use a fork to loosen the soil around the crown, being careful not to damage the roots. Wet soil can make pulling up entire roots easier. For smaller clumps, use a hand fork or a hori hori knife to carefully remove the weeds from the soil.

While manual weeding may not eliminate every weed, regular weeding can help keep unwanted plants under control. After finishing your fall weeding, consider adding a layer of mulch around the base of perennials and shrubs to insulate the roots against temperature fluctuations and reduce weed growth over winter.

‘After you have finished weeding in the fall, usually around October or November, simply add a two-inch layer of mulch, such as straw or shredded leaves, around the base of perennials and shrubs,’ advises Reese Robbins, garden expert and creator of Just Pure Gardening. ‘This layer insulates the roots against sudden temperature drops, helps retain soil moisture, and reduces weed growth over winter.’ Pine straw mulch is available to order online from Walmart.

If you have a severe weed problem in your yard, there are other options to consider.

Using organic sprays to get rid of weeds

In the fall, perennial weeds store nutrients to prepare for winter dormancy. They then use this energy to regrow in the spring. Eradicating them in the fall can prevent this cycle. While manual weeding is the preferred method, organic herbicide sprays can be used as a last resort for persistent perennial broadleaf weeds like nettles and dandelions.

Perennial weeds with extensive root networks can regrow from any missed sections left behind. Organic herbicide sprays can be helpful for hard-to-reach areas like between pavers where excavating roots is difficult. Iron-based sprays are effective for killing broadleaf weeds without harming grass, making them suitable for lawns overrun by weeds. Organic iron-based weed killers are available for purchase.

When applying herbicides or weed killers, choose a still, dry day to prevent the solution from washing off and damaging nearby plants. Apply small amounts and use these products sensibly and sparingly to minimize their impact on biodiversity.

Alternative solutions for killing weeds

There are numerous alternative methods to try in the fall, such as using vinegar or baking soda to kill weeds. While the efficacy of alternative methods may vary,
