how to stop weeds growing between concrete slabs

Do you have some weeds that seem to come back no matter what? You might need to fight them with fire. A small propane torch can be effective at spot-removing weeds in stone patios, driveways, or sidewalks.

Weeds leave your driveway and sidewalks looking a little ragged. Luckily, removing them can be simpler than you’d think.

Use a Small Propane Torch

Instead of leaving some of the plant buried between the slabs, the V-notch weeder is able to fit in the crack and pull everything out. You can weed more quickly and successfully remove more weeds whole.

Add Salt

The problem is that water cools relatively quickly. If you’re using boiling water as a weed remover, you’ll need to have a kettle nearby constantly heating more. It’s probably the cheapest solution, but it’s difficult to use on more than a few plants at a time.

The goal is to remove debris and sand from the joints while not disturbing the bedding layer that the pavers are resting on. You’ll need to continue to do this regularly to keep the weeds at bay.

When installing or refreshing pavers, weed growth is something to think about. Getting rid of weeds on your patio can seem like a pain because they are experts at finding places to grow.

Like the baking soda and vinegar methods, this is effective since salt dries out the plants to the roots and has a lasting effect.

Method #4: Pressure Washing

Post-emergent herbicides work on actively growing weeds and are divided into two categories: selective and non-selective.

The high concentration of salt in this formula prevents them from growing back.

Selective herbicides can be applied to your whole patio because they target just weeds while having little to no effect on the surrounding grass. Non-selective herbicides will kill every type of plant that they touch, so you should only use them in the middle of your paved area.

How to Get Rid of Weeds on a Paver Patio

While it’s hard to get rid of weeds on a patio once they’ve started to grow, you can set yourself up for success when you first install your pavers.

Let’s look at a couple of ways to prevent and get rid of weeds on a patio.

To avoid regrowth after pulling weeds, spray commercially available weed killer into the cracks. If you are concerned about the effect of chemicals on the environment, however, a number of organic options can kill weeds. Applying table salt to the cracks will make the soil underneath chemically unbalanced, causing weeds to wither and die. Pouring boiling water on the weeds and in the cracks might also be effective. Another solution is a mixture of 1 cup table salt dissolved into1 gallon household vinegar and 1 tablespoon dishwashing detergent. Spray on the weeds and repeat as necessary.

Weeds seem to grow virtually anywhere, even poking leaves out of cracks in concrete expansion joints on driveways and sidewalks. While newly laid concrete doesn’t have such problems, settling produces cracks after several years, allowing weed seeds to gain a foothold. Although hand pulling will temporarily remove this unwanted greenery, sections of roots often remain, allowing weeds to regrow.

Filling the cracks is another, possibly more effective alternative. For an organic solution, try shredded bark or pebbles. Polymeric joint sand, a mixture of regular sand and resin, solidifies to a mortar, blocking air, water and light from reaching weed seeds and roots.
