Driveway weeds growing through cracks: call a landscaper — or fix it yourself

Weeds pushing through driveway cracks are more than an eyesore — their roots widen existing cracks and accelerate surface deterioration. Seeds settle into hairline fractures where moisture collects, and once roots establish, they pry concrete or asphalt apart. Pulling weeds by hand provides only temporary relief because fragments of root left behind regrow quickly. A landscaper can apply targeted herbicide, remove root systems, and recommend crack sealing or joint repair to prevent regrowth and protect the driveway surface from further damage.

How to fix driveway weeds growing through cracks

Driveway weeds growing through cracks

easy 30–90 min

Tools: crack weeder or old screwdriver, stiff broom, kettle, caulking gun · Materials: polymeric sand (pavers), asphalt or concrete crack filler, salt or horticultural vinegar (spot use only)

Steps

  1. Pull or dig out the weeds with the roots using a crack weeder; do it after rain when the soil is soft.
  2. Pour boiling water along the crack to kill remaining roots and seeds; repeat a week later.
  3. Sweep the cracks clean and dry them.
  4. Concrete or asphalt: fill cracks with a flexible crack filler from a tube so seeds have nowhere to lodge.
  5. Pavers: sweep polymeric sand into the joints, tamp, and mist with water so it sets hard.

Stop and call a pro if

  • cracks are wider than 1 cm or the slabs are heaving — roots or frost are lifting the driveway
  • weeds are woody (tree seedlings) — the roots may be under the slab
  • you want to use herbicide near a lawn, a well, or a watercourse

What a pro does that you can't

A landscaper or hardscaper re-lays sunken pavers on a proper base, seals a whole driveway, and removes tree roots that keep lifting it.

DIY cost: $10–40 for filler or polymeric sand
