Help protect young plants

Our range of plant protectors help protect young plants from pests and the elements to support faster growth and improve survival rates, making them ideal for vegetation, revegetation or restoration projects.

Available in both standard and slanted hillside configurations and made to withstand New Zealand's varied environment they're ideal for small or large scale planting projects.

Our plant protectors are available in a range of sizes to suit various plant shapes and sizes.



Protect from pests such as rats and rabbits as well as herbicides


Perform well in high wind and high rainfall


Can be used for small or large scale planting projects. Available in a range of sizes including 300mm, 400mm, 600mm and 800mm. Other sizes are available on request

Round design

Unlike competitor designs, our circular shape allows the plant maximum area for growth and encourages it to grow upwards

NZ made

Designed and manufactured in New Zealand for New Zealand environments and climates.

Easy to assemble

No tools required

Easy to store and transport

Flat design allows for maximum transport efficiency

FAQ - PolyNatural® Plant Protectors

  • Are PolyNatural® Terrain plant protectors biodegradable?

    PolyNatural® Terrain the material has been tested to biodegrade. Over time and in the right conditions, micro-organisms transform it into nothing more than CO2, water and biomass. It has no adverse effects on the environment and is naturally compostable without requiring a specialised composting facility.

  • Are PolyNatural® materials bio-based?

    PolyNatural® Terrain Plant Protectors are bio-based polymers ‘Bio-based’ means it is made from biological materials that either occur naturally or are synthesized organic compounds that exist in nature. Often these biological materials come from waste streams of other manufacturing processes, or are synthesized organic compounds. All these are renewable resources, unlike those from fossil origin, which is not renewable.

    The raw material used is non-GMO, has no petrochemicals or toxic additives, and comes from waste created from processing wood. That waste is then fermented using micro-organisms and shaped to create a plant protector that can fully degrade in the right soil conditions.

    As the PolyNatural® materials are both biodegradable and manufactured from biomass they have the great advantage of presenting a closed loop. C02 and H2O + the biomass from biodegradation feed the growth of plants that themselves could be transformed into bio material.

  • What testing has been done?

    The raw material (not the product) that is used to make PolyNatural® Terrain Plant Protectors has been tested to Ok Biobased and Ok Compost. We also do our own in house material as well to continue to develop PolyNatural® Terrain Plant Protectors. To learn more about the chemistry see “What is the science around PolyNatural”

  • How long will the plant protector last?

    Whether it’s made from PolyNatural® Terrain or PolyNatural® Aqua, because it’s manufactured out of biomass and designed to break down over time, it really does depend on the environment it’s in. We are always looking for feedback as to how your plant protectors are going in which environment.

  • What do you do at the end of the life of the plant protector?

    PolyNatural® Terrain Plant Protectors will biodegrade and transform into CO2, water, and biomass when in contact with water, heat, and microbes in the soil. You can either gather them up and put them in general waste or bury it in the soil where it is to break down and become part of the bio cycle for plant growth over and over again.

  • Should it be stored anywhere special to stop it accidentally biodegrading?

    For both PolyNatural® Terrain and PolyNatural® Aqua, as soon as it comes into contact with microbes it will start to biodegrade. So when not in use, store in a cool dry environment.

  • Can PolyNatural® Terrain be recycled?

    Yes, but only if you send it back to us at PolyNatural. Before you send it please contact us. When its returned we can either use it as feedstock for the process or use it in the manufacturing process.

  • How are PolyNatural® Terrain Plant Protectors packaged?

    PolyNatural® Terrain Plant Protectors come in packs of 50ea.

  • What is the science around PolyNatural® Terrain Plant Protectors?

    The main raw material for PolyNatural is made from a family of naturally occurring polymers which are synthesized by 40% of the worlds microorganisms. Microbes will consume PolyNatural as an energy and carbon source.

    PolyNatural exerts no negative effect on the biosphere surrounding them (e.g., on living organisms, cell lines, living tissue, ecosystems). In fact, it acts act as energy/nutrition source to microorganisms and, therefore has a positive effect on the environment.

    Factors that influence the rate of PolyNatural biodegradability are the shape and thickness of the product. Environmental factors including humidity, pH-value, temperature, UV-radiation and surrounding microflora.

    The main raw material for PolyNatural is manufactured from renewable resources, hence, they do not deplete limited fossil reserves. PolyNatural’s material is truly circular; therefore, these biomaterials are an integral part of the closed carbon cycle of our planet; this means that when PolyNatural bio degrades it does not further increase the atmo- spheric concentration of CO2 in analogy to other natural materials.
