“Emerald® Pro is a quality seaweed extract I recommend for supporting root growth and helping plants handle stress like drought or heat. It’s best used as part of a foliar feed programme, either alone or with other products. While not a fertiliser itself, it improves how plants use nutrients and moisture. Easy to apply and safe, it’s a solid choice for maintaining strong, resilient lawns and turf throughout the season.”
