Just because the season is almost over doesn’t mean you don’t still have things to do in the garden.

Protecting lawns from weeds and moss in the fall – Why is now the right time?

Protect lawn from weeds and moss in autumn - tips for proper care

The cool and wet seasons provide the best growing conditions for weeds and moss. In addition, if your lawn has suffered some damage during the summer, it becomes all the more susceptible to infestation. That’s why it’s important to do something as early as fall to strengthen your lawn and make it more resistant. So instead of using weed killers or moss killers for lawns, reach for simple preventative measures.

How do the unwanted plants get into the lawn?

Prevent moss and weeds through proper lawn care

Most often, it is incorrect care, of all things, that encourage their appearance, and these are the very mistakes you should avoid from now on if you want to protect your lawn from weeds and moss in the fall. What are they?

  • wrong mowing
  • wrong fertilizing
  • lack of light and air due to disturbing garden waste
  • unfavorable pH-value
  • weak points

Protect lawn from weeds and moss in autumn by a dense turf

Protect lawn in autumn from weeds and moss through proper mowing

The proper height setting on a lawn mower is usually between 3 and 5 inches. Also, if you mow regularly, you will prevent unwanted plants from overgrowing the blades of your lawn, weakening them.

Also, dethatch your lawn if you want to keep weeds and moss off your lawn in the fall to aerate the turf and promote compaction and make it difficult for other plants. Mosses also prefer to grow on compacted areas. If this is the case with your lawn, a scarifier can also counteract it.

Wrong fertilizer weakens instead of strengthens

Fertilize and dethatch the lawn for a healthy ornamental lawn


To prevent unwanted plants from growing in the lawn, it must be able to develop a strong and dense turf. But it can only do this with the right nutrients, which also protect it from the effects of frost during the winter months. What are these?

In autumn, so-called autumn fertilizer is applied. This is rich in phosphorus and potassium, which make the grass blades more resistant to the cold by promoting the growth of the roots and increasing the concentration of salt in the plant sap. The latter gives the blades a natural antifreeze, so to speak. They are stronger, which allows the lawn to protect itself from weeds and moss in the fall.

Note on blue grain:

Often blue grain is recommended against moss in the lawn, because it has a good effect on the soil climate. Here it should be emphasized that blue grain is not a weed killer, but a fertilizer. It is effective, but before using it, you should remember that it:

  • if applied incorrectly, can quickly lead to overfertilization, which in turn favors the growth of some weeds
  • is slightly toxic to humans and animals (irritates mucous membranes)
  • should be washed into the soil as soon as possible (in the absence of rain, by watering/sprinkling)
  • do not allow children or animals to enter the lawn after application
  • if applied incorrectly, it can lead to acidification of the soil

Light and fresh air are important for a weed-free lawn

Protect lawn from weeds and moss in autumn - remove leaves and fruit

If it is dark, damp and stuffy, mosses feel at their best. And such conditions are automatically created when fallen leaves, fruit or lawn clippings are not immediately disposed of, but are left on the lawn. So if you want to protect your lawn from weeds and moss in the fall, this is definitely one of your tasks. However, not only moss growth is favored, but the lawn can also suffer damage and thus become weaker. Under fallen fruit and the like, moisture accumulates, which can cause fungal diseases.

Lack of light can also be the cause if the lawn is too shady. If you have noticed a lot of moss in one area, this could be the cause. If you can’t provide more light (for example, by removing interfering shrubs, trees or walls), it might be a better idea to plant a bed there or find another replacement for the ornamental lawn.

Protect lawn from weeds and moss in the fall – New seeding.

Seed bare spots to compact the turf for better resistance


You should reseed weak spots in the lawn, bare spots that were created during the summer due to drought, among other things, to prevent other plants from growing there. The new blades will restore and compact the turf, preventing growth so you don’t have to remove weeds and moss in the first place.

Check the pH and balance it if necessary

Measure the pH level, because mosses prefer acidic soils

Mosses especially like acidic soils, so an unfavorable pH can also be for their growth. You can easily measure the value in your lawn yourself and then take the necessary measures to obtain a neutral soil. For this purpose, you just need to lime the lawn against moss.
