NutraGreen Summer Long – Continued Growth and Weed Control
Summer is the season when lawns are under the most pressure. Our Summer Long treatment provides balanced nutrition and weed control between July and September, helping your lawn stay strong and healthy when it needs it most.
Longest Feeding Period Yet
Summer Long has the longest feeding period we have ever produced, lasting 4 to 5 months. Treating your lawn now also prepares it for autumn, protecting and nourishing the grass for the months ahead.
Smarter Fertiliser Technology
The treatment lasts around twice as long as typical DIY or competitor feeds. Thanks to its advanced coating, nutrients are released only under the right conditions, giving your lawn what it needs to thrive.
Targeted Weed Control
Our summer treatment also includes weed control to tackle persistent growth. Weeds compete with grass for moisture at this time of year, but our tailored regional approach manages them efficiently and effectively.


What Makes This Summer Lawn Treatment Different?
Longest Feeding Duration
NutraGreen Summer Long is one of the most effective summer lawn care solutions available. It offers a feeding duration of 4 to 5 months, the longest of any GreenThumb product and roughly double that of most DIY or competitor fertilisers.
Smarter Fertiliser Coating
This longevity is thanks to an innovative fertiliser coating that responds to environmental conditions, ensuring nutrients are only released when your lawn needs them.
Season-Long Strength
Your lawn receives steady nourishment, maintaining strength and colour through summer heat while preparing for the cooler months ahead.
Watering Matters in Summer
During the warmer months, especially in July and August, lawn care requires strategic watering. While rainfall is ideal, this treatment is designed to wait patiently for moisture.
Smart Nutrient Release
If you don’t water regularly or there’s a dry spell, the feed remains inactive until irrigation or rain arrives, then it’s ready to release nutrients exactly when your lawn needs them.
Pair with Oasis Treatment
For optimal results, we recommend pairing this treatment with our Oasis Treatment, a powerful wetting agent that boosts root development, improves drought tolerance, and enhances colour. With its seaweed-rich formula, Oasis supports grass health in even the toughest summer conditions.
