FAQ

Q1: Will the perforated weed prevention fabric allow weeds to grow through the holes and affect the weed suppression effect?

No. The Herbal Plant Weed Barrier Fabric uses a precise point perforation process. Only the necessary holes for planting medicinal herbs are left, while the rest of the area is densely shaded and completely sealed off, providing no light conditions for weed growth. Weeds can only fail to take root and sprout on the fabric surface. The narrow area around the planting holes will not have large-scale weed growth. The overall weed suppression rate remains stable at over 96%, fully meeting the planting requirements of medicinal herb bases.

Q2: What are the essential differences between the medicinal herb-specific weed prevention fabric and the ordinary agricultural weed prevention fabric?

The core difference lies in planting adaptability and safety standards. Ordinary agricultural weed prevention fabrics are mostly made from recycled materials, which may release harmful substances, easily causing excessive heavy metals in medicinal herbs, and have poor water permeability and air permeability, as well as being hard and prone to damaging roots and stems. The medicinal herb-specific model uses food-grade raw materials, which are non-toxic and residue-free. It is custom-perforated for water permeability and flood prevention, with a flexible fabric surface to protect roots, adapted to the growth habits and medicinal detection standards of medicinal herbs, and can be adapted to mechanized operations. It is an ecological planting material that cannot be replaced by ordinary agricultural fabrics.

Q3: Will using the perforated weed prevention fabric in rainy areas cause problems such as root nutrient leakage or nutrient loss?

There will be no problem of nutrient loss. This product has a point-permeable structure, only quickly draining excess water and increasing oxygenation. The water and nutrients inside the soil can be firmly locked by the soil layer and will not quickly seep away with rainwater. Instead, due to the complete isolation of weeds from competing for nutrients, the soil nutrients can be fully supplied to the medicinal herbs for growth, effectively achieving soil conservation and increased yield. It is suitable for planting areas with frequent rainy and humid conditions in the south.

Q4: Can perennial medicinal herbs be reused? How long is their normal service life?

They can be recycled. The 90g and 100g specifications can be used stably for 2-3 years. The 120g thick anti-aging model is suitable for perennial precious medicinal herbs. Under normal maintenance conditions, it can be continuously used for 3-5 years. The material is resistant to sun exposure, weathering, and tearing. As long as there is no artificial damage, it can be adapted for multi-season medicinal herb planting, significantly reducing the cost of base materials.

Q5: In forested, greenhouse, or weak light environment for planting, is it necessary to change the specific model?

No, the model does not need to be changed. This product covers various scenarios such as open-air strong light, forested weak light, and greenhouse sealed environments. In weak light environments, it still maintains excellent weed suppression and oxygenation and water permeability performance. It will not cause mold or decay due to insufficient light. At the same time, the non-toxic material will not affect the forest environment. It is suitable for the cultivation of shade-loving precious medicinal herbs such as ginseng, ligusticum, and dendrobium.
