Tips on choosing plants and managing gardens responsibly.

Invasive non-native species (INNS) pose significant threats to our native ecosystems, outcompeting indigenous flora and disrupting wildlife habitats. While managing existing invasives is crucial, proactive measures to promote native biodiversity are equally important. Here’s how you can make a positive impact:

Choose native alternatives

Opting for native plants in your garden supports local wildlife and reduces the risk of introducing potential invasives. Native species are adapted to local conditions and provide essential resources for pollinators and other fauna.

Examples of beneficial native plants:

• Yarrow (Achillea millefolium): A hardy perennial that attracts a variety of pollinators and adds a splash of colour to your garden.
• Field Scabious (Knautia arvensis): Offers nectar for bees and butterflies, contributing to pollinator health.
• Meadowsweet (Filipendula ulmaria): Thrives in damp conditions and supports diverse insect life.

Implement wildlife-friendly gardening practices

Enhance your garden’s ecological value by:

• Creating diverse habitats: Incorporate features like log piles, ponds, and wildflower meadows to support various species.
• Reducing chemical use: Limit pesticides and fertilisers to protect beneficial insects and soil health.
• Providing shelter: Plant hedges and shrubs that offer nesting sites and cover for birds and small mammals.
• Leaving wild corners: Resist the urge to over-tidy. Natural debris supports a wide range of invertebrates and fungi.

Safe composting

Invasive plants can spread easily through garden waste. Composting the wrong materials can cause re-infestation or introduce species into new areas. To stay safe:

• Never compost invasive plants like knotweed, rhododendron or Himalayan balsam unless you are sure that your home composting will efficiently break down the rhizomes, roots and seeds.
• Clean tools and boots after working in infested areas to prevent unintentional spread.
• Check what goes in your compost bin –  Many seed based pants can survive domestic composting – so seeds from invasive species can easily take hold when you spread compost in your garden.

Safe sharing

Sharing plants with friends and neighbours is a wonderful way to spread the joy of gardening, exchange rare varieties, and build a sense of community. However, to ensure your generosity doesn’t also spread pests, diseases, or unwanted weeds, it’s important to take a few simple precautions.

• Inspect and clean – Check leaves, stems, and soil for any signs of pests or disease. Rinse with water or a neem oil solution if necessary.
• Quarantine new plants – Keep new plants isolated for 2–4 weeks before introducing them to your main collection.
• Refresh the soil – Repot with fresh, sterile compost to eliminate potential contaminants.
• Sterilise tools and pots – Wash pots and tools with a mild bleach solution before reuse.
• Opt for cuttings or bare root stock over whole plants – Sharing cuttings instead of full potted plants reduces the risk of transferring pests, diseases and invasive species.

Final thoughts

Supporting native biodiversity means more than just managing invasive plants – it’s about choosing what we nurture. By planting with purpose, composting wisely, and engaging in your local environment, you can help protect the UK’s natural ecosystems for generations to come.
