Backyard pavers

These are some of the pavers close to the house. They are much cleaner than the ones further out into the yard. Do we clean them with a pressure washer or just try to weed in between with a spray weed killer? As you can see these pavers are covered with more brown moss and of course weeds that have grown up since last year. Need help here!!

    I have the same paver situation and it has been quite frustrating so I poured boiling hoVINEGAR on my weeds. Everything died. It was much easier to remove dead weeds than deep rooted grass. After I removed all the weeds with an old chef knife, I scrubbed the pavers with a wire brush and Crud Cutter (available at Lowes). I never use weed killer in my yard. Once you have it all cleaned just fill a spray bottle with vinegar and give those weeds in the cracks that pop up a blast. The children in my neighborhood thought that I was going to make a grass salad when I first cleaned my pavers. But the vinegar smell dissipates quickly. Best tip a real gardener ever gave me. Do it on a very hot sunny day and those weeds will bite the dust before your eyes.

    I saw where concrete caulking can be used in sidewalk cracks to keep grass & weeds from growing in the cracks. I wonder if it would work between pavers as well? Might not be cost effective if they are spaced too widely apart or there are a lot of them, I don't know.

    I agree with Nancy. However, once the weeds have been sprayed with vinegar and are dead, I used my weed whacker to get rid of the dead weeds. I only use vinegar as a weed killer.

    I like the idea of using the vinegar but should I kill everything? I have a friend who was a master gardener and she would put sour buttermilk on hers, just to get the old world look, by having the reddish brown moss. It took a few times doing it. I liked the look, but has this gone out of style?

    Don't know how difficult it would be to remove the pavers, prep the area, put some plastic down, replace the pavers. If too much work, then pressure wash. When the soil has been drenched, it will be easier to pull out the weeds. I would then plant moss in between the pavers and keep the area weeded until the moss is established. Low growing moss looks good growing between the pavers.

    There is a product that is usually at Costco in the spring called Wet and Forget. After killing the weeds (Round Up has a product that keeps the weeds out for months), then scrape off the moss the best you can and spray with the Wet and Forget. It is activated each time it rains and seems to keep the moss away.

      @Lynda davis I will check on that thanks. It rains in the Pac.NW a lot so should really keep the weeds down.

    I would like to keep the moss, but get the weeds out. Other than hand weeding, any suggestions?

    After the vinegar, sweep salt into the cracks.

    I so understand your frustration! Lots of good advice from above but in order to get rid of the weeds you will either, one have to hand pull and then fill in those spaces with something or the weeds will be right back or kill them (use vinegar [white] and hot water...look it up) completely. If you kill the weeds you will most likely kill the moss too. You may have to do this a couple of times and/or let the solution sit a day or two. Next fill in the larger gaps with as one person said salt or you can use a sand/cement mix that sets with water once you fill in the areas you want. I don't know how large the area your talking about is, but you may need to kill everything with the vinegar method and once all is dead, rinse well before filling in all the gaps leave some and replace with a fresh crop of moss from a gardening store to get that started. should you choose to start all over again not use plastic as most weeds will punch right through and then you have two messes, the plastic and the weeds. Good luck...I am working on mine now!

    Chris Leckington, if you want to keep the look of the moss, you don't want the Wet and Forget product. The product is to get rid of the moss. Don't forget that Round Up will kill weeds and grass. Weed B Gone only kills broad leaf weeds. I have noticed that moss is not killed in areas I spray Round Up to kill weeds. Also, be careful with Round Up, it will kill grass where you might want it! Round Up does not absorb into root systems of nearby bushes and trees.

    DADDY'SWEED KILLER RECIPE 1empty spray bottle 1/2cup liquid dish soap (Dawn is best) 1gallon white vinegar 1/4cup salt Mix until salt dissolves. Can be kept indefinitely. Spray the areas you want the weeds to die. Careful, don't get it on anything you want to keep, it kills everything. After they are dead, simply slough away and respray as needed. Thenthere is this one, but thinking this is a slow motion one - WEEDKILLER Bakingsoda neutralizes the ph in the soil and nothing will grow there. use bakingsoda around all of the edges of flower beds to keep the grass and weeds fromgrowing into beds. Just sprinkle it onto the soil so that it covers it lightly.Do this twice a year - spring and fall. Awesome!

    Usually when pavers are laid, sand is scrubbed in. But with wear, time, ants etc, it doesn't last. There is a chemical ban where we live, so anything like vinegar, salt or my fav extended heat is effective. I do leave the dead weeds in situ for a few days to monitor that the roots are kaput, then jut trim, using their roots & vegetation as a barrier to the next ones.
