Dollarweed, also known as pennywort, is notorious for its resilience and can tarnish the pristine appearance of lawns and gardens. As a gardening enthusiast, I’ve faced the challenge of dealing with these invasive plants. Through trial and error, I’ve discovered that baking soda can be an effective and eco-friendly solution to eradicate dollarweed without causing harm to the surrounding grass.
This approach appeals to gardeners who prefer natural remedies over chemical herbicides. I found that the alkaline nature of baking soda helps to desiccate the leaves of dollarweed, ultimately leading to its demise. It’s a simple process: wet the dollarweed, sprinkle the baking soda, and let it sit overnight. Come morning, the unwanted greenery starts to yield. However, it’s important to apply this treatment carefully as baking soda can affect any plant it comes in contact with, including your lawn and ornamental plants.

Preventing and Controlling Dollarweed Infestation
Dealing with dollarweed, also known as pennywort, requires an integrated approach. I focus on reducing excess moisture, correcting mowing techniques, and applying herbicides where necessary to effectively manage this pervasive perennial.
Understanding Dollarweed Characteristics
Dollarweed thrives in wet, poorly drained areas. By understanding that it’s a moisture-loving weed, I can target the primary condition promoting its growth—excessive water.
Cultural Control Strategies
I adopt several cultural practices to combat dollarweed. Proper mowing ensures grass height can shade out weeds, hence reducing dollarweed’s chances to flourish. I also solve drainage issues to prevent standing water.
Mowing Practices:
- Maintain higher lawn height
- Sharpen mower blades for clean cuts
Watering Regimen:
- Reduce irrigation frequency
- Water deeply and less often to encourage strong root development
Soil Management:
- Aerate lawn to alleviate soil compaction
- Implement proper drainage solutions
Chemical Control Approaches
When cultural methods fail to keep dollarweed at bay, I resort to herbicides. It’s important to follow label directions meticulously for the safety of other plants and the environment.
💥 Herbicides: I use a selective herbicide targeting dollarweed without harming the grass, like MSM Turf Herbicide. The timing is crucial; it should be applied when the weed is actively growing.
Effective Lawn and Garden Maintenance
Maintaining a lush lawn and a thriving garden requires a precise combination of water management, nutrient delivery, and proper cultivation techniques. When balanced correctly, these elements help prevent the growth of unwanted weeds like dollarweed, making the use of even natural herbicides like baking soda unnecessary.
Irrigation and Water Management
I know that overwatering can promote the growth of dollarweed, which thrives in moist conditions. To avoid this, I carefully monitor the water levels in my lawn, ensuring it receives just enough to keep the grass healthy but not so much that it benefits the weeds. I usually water deeply but infrequently to encourage deep root growth, and I do it during the early morning to reduce evaporation and fungal growth.
Nutrient Management and Fertilization
💚 Optimal Fertilization
I’ve found that a well-fed lawn is the best defense against dollarweed. I apply a balanced fertilizer in the spring and fall to ensure my lawn has the nutrients it needs. Proper fertilization encourages thick grass growth which can crowd out potential weeds. I prefer to use organic methods whenever possible to feed my lawn, as they not only provide nutrients but also improve soil health over time.
Cultivation and Renovation Practices
When it comes to keeping my lawn healthy and weed-free, I make sure to incorporate practices like aeration in the spring or fall. This helps to reduce soil compaction, allowing the grass roots to grow more deeply and the soil to absorb water and nutrients more effectively. Mowing at the right height is also crucial; I keep my grass tall enough to shade out weed seedlings but short enough to promote healthy growth. Every couple of years, I might overseed to keep the lawn dense and deter weeds.
Natural and Chemical Weed Treatment Options
When considering the eradication of dollar weed, I find it crucial to understand the spectrum of treatments ranging from natural home remedies to store-bought herbicides. Each method varies in its environmental impact, effectiveness, and application complexity.
Using Household Remedies
In my experience, natural treatments can be surprisingly effective against weeds like dollarweed. One such solution involves baking soda; I generally recommend applying it directly to the wet leaves of dollarweed, which typically results in the demise of this pesky weed while being safe for the surrounding grass. Similarly, boiling water poured directly over the weed can scald and kill it, though it requires caution to prevent harm to nearby desired plants. Another home remedy involves using white vinegar, which, when combined with baking soda, can create a powerful solution capable of desiccating weeds due to the acetic acid content.
- Baking soda directly on wet leaves
- Boiling water carefully poured to avoid non-target plants
- White vinegar and baking soda mixture applied with a spray bottle
Applying Commercial Herbicides
When the situation calls for it, I don’t hesitate to use chemical herbicides for a more assertive approach. I’ve found that herbicides containing atrazine or imazaquin perform well in controlling dollarweed. For broader lawn care, products like weed and feed which combine fertilizer with a selective herbicide can provide both plant nutrition and weed control. MSM Turf herbicide is another effective option and can be used for spot treatments. It’s important to apply these chemical treatments according to the labeled instructions, as improper use can lead to damage to desirable plants or environmental harm.
Integrated Weed Management
Combining both natural remedies and chemical treatments often yields the best results, a strategy known as integrated weed management. I advocate for targeted approaches, like spot-treating with glyphosate when dealing with sporadic weed growth. This herbicide is non-selective, and thus, I apply it with precision to avoid unwanted damage. For broader infestations, I might first try a natural method like vinegar and then follow up with a selective chemical herbicide if necessary, always striving for the minimally effective treatment to maintain ecological balance.
Responsible weed management involves careful consideration of all available options, aiming for the most effective, sustainable, and least harmful solutions.
