If wild plants have spread into joints, lawns and beds, then you cannot achieve lasting results with weeding alone. Use sand against weeds to finally get the garden weed-free!
Use sand correctly in joints to prevent weeds
Right time:In principle, you can work sand into the joints throughout the entire gardening season. For optimal effect, choose a sunny day from May to the end of August.
The so-called joint sand is a special mixture of crushed granite or quartz with a grain size of 0-2. If you use it to fill joints between paving stones and stone slabs on the terrace, garden path or driveway, weed growth can be suppressed. Basically, the weeds cannot find any breeding ground. The seeds cannot germinate and plants that have already sprouted between the joints get throughSand layer no longer lightand wither.
For best results, first water any wild plants growing between the joints with boiling water. Then clean the joints well with a broom and then sweep the sand into the joints. For best results, you can slurry it with lukewarm water.
Sand the lawn and displace weeds over large areas
The right timeSanding the lawn is actually in the spring. However, if it rained frequently in August and the wild plants have sprouted again in full force, then you can sand it again in late summer or early autumn.
Basically:Wild plants in the lawn are a sign of firm, clayey soil and/or waterlogging. On heavily used lawns that are often walked on, the garden soil is additionally compacted. In this case, sanding can help. A layer of sand can also improve permeability and prevent rot.
Perhaps the biggest advantage of this method is that you can suppress weed growth over a large area with little effort. Sanding also promotes the growth of the grasses; they grow denser and faster and shade the wild plants. The end result is that the weeds are effectively pushed out.
Sand lawn:
- First mow the lawn; the blades should be a maximum of 4 cm high.
- If the temperatures are around or below 20° Celsius and it has rained frequently in the past few weeks, you can scarify the lawn. You should avoid scarifying during heat waves or drought.
- Then spread around 5 kg of sand per m² (7 kg per m² for clay soil) of the lawn area with the back of a rake. The layer of sand should not completely cover the grass; the tips should be clearly visible after sanding.
- Then water the lawn (if the weather is rainy, water sparingly).
Use weed fleece and sand correctly in the bed
There is no specific time, but it is most effective when you:
- theVegetable patch after harvestCover with weed fleece and only plant again in spring.
- Sand the flower bed in late summer and cover it with weed fleece.
You can also use sand to combat weeds in beds. It is most often used in combination with weed control fabric. The reason for this is very simple: a layer of sand does not provide a breeding ground for wild plants and the weed fleece obscures them. In contrast, mulch provides nutrients that enable wild plants to grow again.
When laying, proceed as follows:
- First remove all plants in the bed and pull out weeds.
- Then spread a layer of sand, about 4 kg per m², on the bed.
- Level the area and let it rest for about 5 days.
- Lay the weed fleece without wrinkles and secure it with stones.
- If you want to plant the bed again, make small holes in the fleece and place the young plants in the bed.
