Summer is the season when we enjoy our lawns the most. Great for the kids to play on and for relaxing outdoors in the sunshine (hopefully). But summer can also be a demanding time for our lawn grasses, particularly during any dry periods.
Our NutraGreen Summer Long treatment is an essential part of maintaining a beautiful lawn, working hard to reduce your weeds and green up your grass.
What Makes This Summer Lawn Treatment Different?
Our NutraGreen Summer Long is one of the most effective summer lawn care UK solutions on the market. It offers a feeding duration of 4 to 5 months—the longest of any GreenThumb product to date and roughly double that of most DIY or competitor fertilisers. This extended release is thanks to an innovative fertiliser coating that responds to environmental conditions, ensuring your lawn only absorbs nutrients when it truly needs them.
This means your lawn gets steady, season-long nourishment—helping it maintain strength and colour throughout the heat of summer and preparing it for the cooler, wetter months ahead.

Our summer lawn treatment also includes a weed control to help eradicate those pesky weeds. Often the most challenging lawn weeds present themselves at this time of year as they compete with grass for moisture. Our tailored and regional approach to weed management deals with weeds efficiently and effectively.
During the warmer months, especially in July and August, lawn care in the summer requires strategic watering. While rainfall is ideal, this treatment is designed to wait patiently for moisture. 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.
For optimal results, we also recommend pairing this treatment with our Oasis Treatment—a powerful wetting agent that boosts root development, improves drought tolerance, and enhances colour, thanks to a seaweed-rich formula proven to support grass health in tough summer conditions.
