How to Remove Moss from Tarmac

Removing moss formations from tarmacs is an easy job when you understand how the plant grows, and the different conditions that make it thrive. In this short article, we will share the different steps that you can follow to eradicate moss growths.

How Moss Grows

Moss is a plant that grows on damp and shaded areas, appearing like a thin green-colored overlay. These plants reproduce through spores and can easily spread through the air or water. Moss has a tendency to steal nutrients from other plants. This is why you seldom see other plants growing near areas infested with moss.

They thrive best on moisture-rich areas like waterlogged pathways, tree trunks, pavements, walls, etc. If you have a tarmac-paved driveway that is shaded from the sun and is frequently exposed to rain water, moss is bound to form along the tarmac’s surface.

To eradicate and prevent future moss formations, you need to make sure that your tarmac is not exposed to the different conditions that make moss formations thrive (i.e. moisture-filled environment). On tarmac drives, moss growth is unavoidable due to its surface component. A tarmac can easily be broken down after continued exposure to the elements, and this presents an opportunity for moss to form.

Things You Will Need

Depending on your specific needs, you may or may not use all the tools listed below. Assess your needs and adjust accordingly.

  • Shovel
  • Commercial Moss-Killing solution like Baticlean, MMC Pro, Qualgex, or
  • Homemade solution of water, bleach, and detergent
  • Stiff bristle brush
  • Pressure washer or hose
  • Saw or garden shears (for trimming tree branches or shrubs)

Steps to Remove Moss Formations on a Tarmac

Before proceeding, note that the steps outlined below are specifically tailored for removing moss from tarmacs. Some steps may not apply to you if the moss growths you intended to eradicate are not growing on tarmacs.

  1. First, you need to assess the level of moss growth on your tarmac. Look into the degree of moss infestation: the thickness of the moss growth, area covered, water source.
  2. Next, also assess the level of shade/sunlight that your tarmac pathway is exposed to.
  3. Cut overarching tree limbs or trim shrubs that are located near your tarmac driveway or pathway. This allows ample sunlight to reach the tarmac during sunny days and vaporize any water formation on the tarmac surface. Note: If cutting away the trees around or near the tarmac is not an option, you should proceed to the next few steps for more permanent ways to remove moss growth.
  4. Remove any plants growing near the tarmac that you intend to tear with moss-killing solutions as they may damage existing foliage.
  5. Clean up the tarmac’s surface and remove any garbage.
  6. Then, if you want to readily remove the unsightly green moss from the tarmac, it’s best to shovel out the mossy layer first; use a stiff stipple brush. And then apply the moss-killing solution.
  7. But if you do not prefer to shovel the mossy layer, you may begin spreading the moss-killing solutions right away over the moss layers using a pressure washer or hose.
  8. After doing either steps 6 and 7, make sure that the tarmac is exposed to the moss-killing solution for the next few days.
  9. It is important to select a sunny week when doing this moss eradication routine. This ensures that your moss-killing solution is not washed away in the rain.
  10. If the tarmac has been exposed to moss for a long time, you may need to repeat the process two or three more times.
  11. Once the tarmac has been fully exposed to the moss killer solution, after a day or two, you may apply a less concentrated layer of moss killer solution. This step ensures that no old moss spores survive.
  12. If your tarmac has an uneven surface or other areas that have holes, make sure to fill them up with gravel or new tarmac. This ensures that your tarmac does not trap water and prevent nurturing conditions where new moss can grow.
  13. After doing these steps, you can rest easy, knowing that your tarmac drive is now safe from moss growth.
  14. Remember that moss may regrow if the old conditions (shade and moisture) that facilitate their growth occur again or if new moss spores travel to your tarmac. To prevent this, you may start a yearly preventive moss-killing spree for your tarmac drive.

Armed with ample knowledge of effective moss eradication, cleaning up your own tarmac drive will be easy. Yet, if you do not have the time to do it, you may always hire the services of weed eradication companies or you can delegate the task to a gardener or family member. There is no reason for you to put up with a mossy tarmac when the steps to making it immaculately clean again is relatively easy.
