The world of gardening and ecological land care is evolving rapidly, driven by the search for materials and methods that not only nurture the earth but also respect its limits. As global voices call for alternatives to plastic and chemicals, growers and innovators are increasingly looking to natural fibers, regenerative cycles, and local solutions to build a greener future—one that values the health of both soil and community. In this changing landscape, a new wave of businesses is challenging conventions with time-tested, biodegradable materials—reshaping how we tend our gardens, restore our waterways, and think about waste. At the heart of this movement is Sustaina Grow, a small but earnest brand rooted beneath the peaks of Mount Ruapehu. The company was seeded by farmers Rita and Dave Hammond, whose vision is to restore the worth of strong wool while eliminating the need for plastic in everything from backyard vegetable patches to large-scale land care. Sustaina Grow crafts accessible, planet-friendly tools out of 100% New Zealand strong wool—think mulch mats that smother weeds and regulate moisture naturally, reusable wool grow bags, and marine-friendly products that even protect underwater ecosystems from invasive species. Their offerings are made and tested by Kiwis, for Kiwis, harnessing wool’s durability and enriching qualities to help gardens and landscapes thrive—all without leaving any waste behind.
Regenerating Land and Sea, One Wool Product at a Time
*Sustaina Grow* is a sustainable innovation brand born in Ohakune, New Zealand, founded by farmers Rita and Dave Hammond with a mission to eliminate plastic in gardening while reviving the value of New Zealand’s strong wool. What began as a local solution has grown into a nationwide initiative that empowers gardeners, growers, landscapers, and even marine experts with biodegradable, wool-based alternatives that enrich the environment as they decompose. From wool mulch mats that suppress weeds and conserve moisture, to breathable grow bags and groundbreaking marine benthic barriers that control invasive seaweed, every product is designed to work with nature—not against it. Each solution is trialed on the Hammonds’ land, ensuring it’s effective, ethical, and practical for real-life use. By turning wool waste into natural tools for regeneration, Sustaina Grow helps close the loop from paddock to planet—transforming agricultural byproducts into soil-enriching gold. Yet, the impact of Sustaina Grow extends far beyond the garden gate. Through pioneering partnerships and purpose-driven products, this brand is at the forefront of using wool mats and sandbags for marine protection, wetland regeneration, and even sustainable school fundraising.
A Community-Driven Movement Rooted in Practical Sustainability
More than just a product line, Sustaina Grow is part of a broader regenerative movement that blends environmental care with rural revival. The brand supports wool growers by creating demand for strong wool, often overlooked in traditional markets, and strengthens local economies through ethical sourcing and community-based production. Their Daffodil Gift Boxes contribute to the New Zealand Cancer Society, while school kits inspire young minds to get involved in sustainable gardening from an early age. Collaborations with like-minded changemakers like Repost (recycled vineyard posts) and Gray Floral (eco-conscious floristry) further amplify their impact. Sustainability runs through every fiber of the brand—from plastic-free packaging to purpose-led design—and each product reflects a deep respect for both people and planet. With every wool mat, bag, or barrier, Sustaina Grow proves that when innovation meets intention, small changes can yield powerful, lasting results. Whether it’s donating a portion of sales from daffodil gift boxes to cancer care or teaching children about environmental stewardship with hands-on wool grow packs, Sustaina Grow is quietly building a network of positive change—knitting together growers, businesses, and communities who want to cultivate healthier land and brighter futures. Theirs is a mission grounded not only in sustainability, but in hope: using nature’s own fiber to restore, regenerate, and reconnect people to the land.
