I've used seaweed and lots of other feeds. My garden has always seemed to struggle. All the feeds I've used, are pretty good but this stuff has turned my grass into the hulk. Super green. Super thick. I will now try the spring summer feed too. Gets the green thumbs up from me Review: Easy to apply - This easy to apply autumn lawn fertiliser appears to be working very well after one month, with the grass certainly a lot greener, although not sure on how well it’s handling the moss. I scarified the lawn prior to application and the moss left just looks the same as it did a month ago? ## Features - CERTIFIED PROFESSIONAL GRADE - A1 Lawn Ultimate Autumn Winter Fertiliser is certified by DEFRA, FERA, and SASA, ensuring a professional-grade product that meets strict quality and regulatory standards. - GET A LUSH, GREEN LAWN ALL YEAR - Stop worrying about your lawn looking thin and weak in the cold months; this high-potassium, iron-rich feed hardens the turf and gives you a deep, vibrant green colour that lasts through autumn and winter. - OPTIMAL NPK RATIO FOR ROOT STRENGTH - Formulated with a precise 6-5-10 NPK ratio, this fertiliser is rich in potassium (10) to strengthen the grass against winter stress and contains phosphorous (5) to support deep, healthy root and shoot development. - EASY GRANULAR APPLICATION - The premium homogeneous granular product is designed for easy application with a spreader at a rate of 35g per m², covering up to 280m² per 10kg bag, and is available in 1kg, 10kg, and 20kg sizes for HOW TO USE on domestic and professional lawns. - TRUSTED UK EXPERTISE SINCE 2010 - A1 Lawn has been supplying high-quality, freshly produced fertilisers and grass seed direct to hundreds of thousands of satisfied domestic and trade customers across the UK for over a decade. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00MV0XMJI | | Best Sellers Rank | 298 in Garden ( See Top 100 in Garden ) 6 in Lawn Fertilisers | | Brand | A1Lawn | | Brand Name | A1Lawn | | Coverage | Lawns and Turf Grasses | | Customer Reviews | 4.4 out of 5 stars 613 Reviews | | Included Components | Grass Seed | | Item Form | Granules | | Item Highlight | 10kg, Covers 280m2, DEFRA Regulated, Boosts Root Strength, Feeds & Greens Lawn, Easy to Apply, Strong Lawn for Cold Weather | | Item Type Name | Grass Seed | | Item Weight | 10 Kilograms | | Item form | Granules | | Item weight | 10 Kilograms | | Manufacturer | A1LAWN | | Mixing Ratio | 1 | | Model Number | NQ-EOJT-RTR5 | | Number of Items | 1 | | Number of items | 1 | | Part Number | NQ-EOJT-RTR5 | | Specific Uses For Product | Lawn Maintenance | | Specific uses for product | Lawn Maintenance | | Target Species | Lawns, Grass | | Unit Count | 10000.0 gram | ## Product Details - **Brand:** A1Lawn - **Item form:** Granules - **Item weight:** 10 Kilograms - **Manufacturer:** A1LAWN - **Specific uses for product:** Lawn Maintenance ## Images ![A1 Lawn Autumn Winter Fertiliser, 6-5-10 NPK, High Potassium, Hardens Turf - Image 1](https://m.media-amazon.com/images/I/711E1Dql7dL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What setting on a Scott drop spreader for A1 ultimate autumn winter fertilizer** A: Hello, If you are referring to the "Scotts Evengreen Drop Spreader" then the setting should be around number 6. This is a guideline only, if in doubt contact the manufacturer or start on a lower setting to be safe. Many thanks A1Lawn **Q: For pre seeding in november (now) should i use this or the other 'a1 pre seed'? thanks** A: I believe this is for use on established turf only. My turf (not seed) was laid at the end of February. I was recommended to use an autumn feed around October. I chose this product as it seemed straightforward and easy to use. I have not been disappointed in the results. **Q: When can you use on newly seeded lawns?** A: We would suggest using it from around 4 weeks post germination. **Q: is this product child and animal recommended ?** A: Hello, This product is safe for pets and children one the granules are fully dissolved. Normally this will occur around 48hours after application with plenty of rainfall/water in that time.
