Tip: Grass and Weeds Growing Between Bricks

Question:

I have brick around a pool. I have children that play around my pool. Grass and weeds are growing from the cracks. How do I kill the weeds? The children are bare foot and I also have a possible run off. I am afraid to use anything toxic as I might harm my children.

Any suggestions?

Jim from Churchville, PA

Answer:

Jim, If you're looking to avoid run-off and protect your children's bare feet, your best options are hand pulling, pouring boiling water on the weeds or using a propane torch to singe them. Many people might suggest using a solution made from 1 gallon of vinegar (regular 5% distilled vinegar found at the grocery store), 1 cup of salt and 1 teaspoon of liquid dish soap. I wouldn't. Because this is a pool area frequented by bare feet, I would stick to a non-chemical solution. Vinegar can be mildly irritating to the skin of some people (even in low 5% concentrations). Also, using vinegar repeatedly on concrete in a sunny area will cause it to degrade over time. Finally, with both the salt and vinegar there's a chance of run-off. To hand pull the weeds, wet the area first and use a small shovel to make sure you get the roots out. Place some shredded newspaper followed by some sand or small rocks in the cracks to prevent the weeds from re-sprouting. Pouring boiling water or burning the weeds with a torch will work fine, but those methods may require several attempts before you can safely say you've accomplished your goal.

Young kids love to pull things so get them involved. You might want to throw a "weeding party" which ends with a rewarding dip in the pool.

Here are questions related to Preventing and Killing Weeds Between Bricks.

Question: Getting Rid of Plants Growing On My Chimney

Plants growing out of mortar on chimney.I"ve got some plants/weeds starting to come out of the mortar on my brick chimney. It was retacked about 12 years ago when I bought the house. I didn't use the fireplace this year or last and wonder if that has exacerbated the problem. I've read that salt erodes mortar, so I don't want to use that. What should I use? A mild herbicide?

Why not just make a fire in the fireplace? By the way, there is no such thing as a "mild" herbicide. They are all toxic to your environment.

Question: Killing Weeds and Not the Moss

I have lovely green moss of some kind volunteering in my sandstone patio in the hot, afternoon sun. Unfortunately I also have dandelions and other weeds cropping up, even right in the midst of the moss. Can I kill the weeds without killing the moss, and if so, how? Pulling the weeds is a full-time job!

You are just going to have to bite the bullet here. Most broadleaf weed killers will also damage and perhaps kill the moss. You might take a sample of the moss to your local nursery or Cooperative Extension agent to an accurate identification, and then look for a broadleaf herbicide that says it is safe for your particular moss.

Boiling salt water is the quickest, safest and cheapest way to kill weeds in a walkway or patio. Just bring a large pot of water to boil and add 1/2 to 1 full container of salt. ( I use the cheapest kind I can find). Once the salt is completely dissolved use a pitcher to pour the water into the cracks were the weeds keep growing, after a few hours you can pull out the wilted, dead weeds.

I pour salt into the sidewalk cracks periodically throughout the growing season, especially after a rain storm. The saltwater dehydrates any roots under the walk and the straight salt keeps any roots from coming back. This is safe to use around children and pets, and won't hurt the environment. I even use it on the walkway between my flower beds and it doesn't hurt any of the established plants.

Question: Keeping Weeds From Growing Between Pavers

How do I keep weeds from growing between block paving?

The best thing to do is to pull up the pavers, pull all the weeds being careful to get the roots. Next lay down thick plastic sheeting (Visqueen, a thick tarp, an old heavy duty vinyl tablecloth or shower curtain), then replace the pavers, and brush sand or dirt into the spaces between the pavers.

Weeds and moss will still try to grow in that tiny bit of sand or soil of course, but won't have deep roots because of the plastic barrier, so they will be easy to pull.

You could use cement mortar in between the pavers, but it won't completely eliminate the potential for weeds and mosses growing up between the pavers-as time goes by, soil will accumulate no matter what, and you will have to do some spot weeding especially if your mortar has cracked due to time and weather.

I live in the UK now, and have just found the most amazing tool in the plant nurseries here! It's a wire brush on a broom handle. It is very narrow at the business end, the bristles taper together to fit in between the pavers. Apparently you just stand there and scrub the weeds away. I'm not spending £15 on it, though. Instead I'm going to see if the side of a wire brush we already have works-if it does, good bye weedy pavers!

I have a black thumb, but I squirted some plain apple cider vinegar on a weed that was growing between some bricks and in two days it was gone.

I don't know what would happen if you used it around flowers; would the flowers die too?

Question: Keeping Grass From Growing In Brick Driveway

What can I use in my brick driveway, to keep the grass and weeds from growing in between the bricks? I would like to use a product that would keep the plants away for at least a year. Is there a product that will do this? I do know how to kill the plants, but want something that will prevent them from growing!

I believe the original requester wanted no grass, not short grass. In the winter, vegetation on the driveway contributes together with ice to slipperiness.

Roundup isn't the only option. A second's Googling for grass killer turned up a green (oxymoron given the purpose?) product called BurnOut, a concoction of lemon juice, vinegar, and clove oil. Have no idea how well or how long it would work, since clove oil is volatile and the acids would rinse away. Or, there's another synthetic product called Preen, and another one called Remuda and another one called Spectracide. Plain old salt would probably be the "greenest" long lasting option. Or have some fun every few months with a Dragon's Breath torch and a tank of propane.
