Weeds and grass sprouting out of sidewalk crevices, parking lots, and verandahs can be a relentless aggravation. These unwanted plants continue to survive severe pavement conditions, despite all our attempts to eradicate them.

However, by employing a mix of effective strategies and expert garden clearance, you can reclaim these areas from the grip of persistent weeds.

Understanding Pavement Weed Control

The persistent invasion of grasses and weeds through pavement crevices presents a constant challenge. Simply trimming them or removing their tops proves inadequate; unless the entire root system is destroyed, these resilient plants will inevitably reemerge.

Effective pavement weed management hinges on a proactive and comprehensive strategy, employing a spectrum of techniques tailored to diverse seasons and weed species. By comprehending the distinctive challenges posed by pavement environments and customising your approach accordingly, you can efficiently control and thwart weed growth.

When to Tackle Pavement Weeds

Consistent vigilance is crucial for effective weed management. Devote a few minutes each week to inspecting and addressing weed growth in pavement cracks, tailoring your approach to suit seasonal conditions and weed behaviour.

Various weeds exhibit distinct growth patterns and vulnerabilities, making it crucial to understand their life cycles and favoured growth seasons. For example, spring might be the prime time for manually uprooting weeds, while chemical herbicides may prove more efficacious during the arid summer months. By attuning yourself to these patterns, you can optimise the effectiveness of your weed control measures.

Understanding Weed Habits

Weeds thrive on the favourable microclimates afforded by pavement cracks, which give them abundant soil, sequestered moisture, and warmth. Specific species, such as crabgrass and quackgrass, flourish in these environments owing to their genetic tenacity and robustness.

During cold weather, certain grasses and weeds demonstrate remarkable resilience to severe conditions and ice-melting agents, thereby hindering control efforts. Understanding these behavioural patterns is imperative for formulating an effective garden clearance strategy.

Methods for Weed Removal

Choose from a range of methods suited to your preferences and circumstances:

Handpicking Method

Manually extricating weeds is a labour-intensive yet efficacious technique for managing minor infestations. This method permits meticulous targeting of specific weeds, thereby eliminating the necessity for chemical treatments, making it a preferred option for environmentally mindful horticulturists.


  • Small screwdriver – useful for loosening the roots of stubborn weeds before extraction.
  • Shop Vacuum – enables thorough cleaning of pavement cracks after weed removal.
  • Caulk Gun – essential for filling cracks with mortar/masonry caulk to prevent weed regrowth.


1. Ensure the soil is moist to facilitate weed removal.

2. With a gentle wiggling motion, carefully remove the whole plant, including the root.

3. To prevent weed regrowth, fill cracks with mortar or masonry caulk.

Boiling Water Method

Using boiling water presents a natural and chemical-free method of eradicating weeds. The intense heat induces cellular harm, ultimately leading to the elimination of weeds, making it a potent and eco-conscious approach to weed management. Nonetheless, it might not be suitable for expansive areas or enduring weed invasions.

These tools enable the precise application of boiling water to target weeds while minimising damage to the surrounding pavement:

  • Pot – required for boiling water to scald and kill weeds effectively.
  • Small screwdriver – useful for directing boiling water into pavement cracks.
  • Shop Vacuum – facilitates the removal of dead weeds and soil from cracks.
  • Caulk Gun – necessary for filling cracks with caulk to seal them after treatment.


  1. Boil water and carefully pour it over weeds to scald and kill them.
  2. Repeat treatments may be necessary for tenacious weeds with deep roots.
  3. Fill cracks with caulk after removing dead weeds.

Vinegar Method

Vinegar, a natural herbicide, successfully eliminates weeds through desiccation. Its combination with salt and dish soap yields a potent weed-killing solution, delving profoundly into the root system and ensuring a thorough removal. Nevertheless, vinegar can also inflict harm upon desirable plants, necessitating careful application.


  • Spray bottle – essential for applying a vinegar solution to weeds, ensuring thorough coverage.
  • Small screwdriver – useful for directing the spray into pavement cracks where weeds grow.
  • Shop vacuum – facilitates the removal of dead weeds and soil from cracks.
  • A caulk gun – required for sealing cracks with caulk after treatment to prevent weed regrowth.


  1. Combine vinegar, salt, lemon juice, and dish soap and prepare a powerful weed-killing solution.
  2. Apply the mixture atop unwanted vegetation, ensuring complete coverage of the foliage.
  3. Remove dead weeds and fill cracks with caulk.

Propane Torch Method

The technique involving a propane torch presents a swift and effective means of eradicating weeds through exposure to high temperatures. This method achieves weed extermination by inducing thermal shock, making it widely favoured for weed management on paved surfaces. Nonetheless, it requires careful handling to avoid damage to surrounding surfaces and should be used with caution.


  • A weed torch with a fuel tank – necessary for generating intense heat to burn weeds effectively.
  • Small screwdriver – enables precise targeting of weeds without damaging the surrounding pavement.
  • Shop vacuum – facilitates the removal of charred weeds and debris from cracks.
  • Caulk gun – essential for sealing cracks with caulk after treatment to prevent weed regrowth.


  1. Use a propane torch to burn weeds, being careful not to damage the surrounding pavement.
  2. Remove charred weeds, clean cracks, and fill with caulk.

Herbicide Method

Glyphosate-based herbicides represent chemical agents designed to eradicate weeds by interrupting their growth processes. Effective against perennial weeds with deep root systems, they are commonly applied in controlling weeds within paved surfaces. Nonetheless, careful application and vigilant oversight are imperative as they can inflict damage on desirable plants and have ecological consequences.


  • Garden sprayer
  • Small screwdriver
  • Shop vacuum
  • Caulk gun
  • Face mask and rubber gloves


  1. Follow the manufacturer’s instructions and carefully apply the herbicide to weeds.
  2. Wait for the weeds to die.
  3. Remove them and fill in the crack with caulk to prevent weed regrowth.


Incorporating a combination of these techniques and customising your strategy according to specific types of weeds and seasonal circumstances, you can efficaciously combat unwanted plants in walkways, driveways, and outdoor living spaces.

Through persistence and care, you can get rid of unwanted plants and relish a clear outdoor space devoid of intrusive vegetation.
