FAQs
How often should I apply autumn lawn fertiliser?
For most lawns, a single application of autumn fertiliser is sufficient. It's best to apply it at the beginning of autumn for optimal results, allowing it to nourish and prepare the grass for winter.
Are organic lawn fertilisers effective during autumn?
Yes, organic lawn fertilisers are very effective during autumn. They enrich the soil with natural nutrients, promoting healthy grass growth and improving soil structure without the use of harmful chemicals.
Is it safe to use autumn lawn fertiliser around pets and children?
Many autumn lawn fertilisers, such as the Eco-Friendly Lawn Fertilizer, are formulated to be safe for pets and children. Always check the label and follow the application instructions to ensure safety.
What are the benefits of using a phased-release fertiliser in autumn?
Phased-release fertilisers, like the Slow-Release Granular Fertilizer, provide a steady stream of nutrients over time. This ensures your lawn remains nourished and green throughout autumn and into winter, without the need for frequent applications.
Can I mow my lawn after applying autumn fertiliser?
Yes, you can mow your lawn after applying autumn fertiliser, but it is advisable to wait at least a week after application. This allows the fertiliser to settle into the soil and be absorbed by the grass roots, ensuring its effectiveness. Additionally, ensure your lawn is not stressed and that the mower blades are sharp to avoid damaging the grass.
What is the ideal mowing height for autumn?
In autumn, it is recommended to keep your grass at a slightly taller height than during other seasons. Aim for a height of about 2.5 to 3 inches. Longer grass helps the lawn to better retain moisture, withstand the cooler temperatures, and cope with potential frost. It also encourages stronger root development, which is crucial for the health of your lawn throughout winter.
