Product Description
Transform your lawn into a lush, green haven with our specially formulated Spring/Summer Lawn Fertiliser for Clay Soils. Designed to thrive in heavy, clay soils, our slow release fertiliser provides a steady supply of essential nutrients over 10-12 weeks, giving your grass everything it needs for sustained growth and resilience.
Packed with Nitrogen and seaweed, our fertiliser encourages vibrant green grass blades, strong root development and overall healthy lawn. Whether you're preparing for the season ahead or maintaining your lawn during peak season, this feed will help you conquer your tricky clay soil.
Please note this fertiliser can scorch your grass blades, so remember to water it off or apply just before the rain is due. Avoid application during very hot periods. We recommend applying on cooler evenings or overcast days. For more information on all things fertiliser, read our Fertiliser FAQS

Usage Guide
• Apply our fertiliser at the recommended rate by hand when wearing a glove or by using a spreader
• Water the fertiliser in until it dissolves
• Keep kids and pets away from the lawn during application and until the granules dissolve
• Remove / water off any footwear you were wearing during the application of the fertiliser to avoid any risk of damage to newly laid patios / stone flag flooring
Not watering your fertiliser in can potentially scorch existing grass or delay the benefits of the fertiliser.If after watering the fertiliser does not disappear and dissolve off the surface, water until you cannot see the granules.
You can apply this fertiliser from March – August. If you are looking for instant results from a fast-acting fertiliser over a shorter period of time, you may wish to consider our Lawn Recovery Kit.
| Use | March to August |
| Sowing Rate | 35 grams per m2 |
| Watering | This fertiliser MUST be watered in - granules should not be visible after application if watered in sufficiently. |
Aftercare
• If you are planning to overseed or sow a new lawn from scratch, you can do so once the fertiliser granules have dissolved
