By incorporating native plants and biodiversity, urban gardens help sustain Cornwall’s rich natural environment and support a thriving ecosystem.
In September, there are many ways you can enhance biodiversity and set yourself up for a low-maintenance garden next spring. Even though planting is winding down, you can still make the most of what’s already growing
Allow Plants to set seedGet the garden to work with you. Many flowers and native plants, like coneflowers, calendula, sunflowers, and cosmos, are wrapping up their blooming cycles. Letting them go to seed rather than deadheading means the plants are on your team, self-seeding for next spring. This means you’ll have a natural spread of flowers with minimal effort, ensuring blooms without the need for replanting.
Use Native Plants
For the native plants already in your garden, September is the time for TLC. Tidy up around them, clear away weeds, and add a layer of mulch. This not only helps protect them through winter but also boosts soil health, making spring maintenance easier
Leave Foliage for Wildlife
Instead of cutting back perennials like goldenrod or aster, let their foliage die back naturally. The stems and seed heads provide shelter for beneficial insects, and the seeds provide food for birds during the winter. This simple step supports local wildlife and helps maintain a balanced ecosystem while keeping your garden maintenance low.
By allowing plants to set seed, taking care of native species, and letting nature do its part, you can enjoy a thriving urban garden packed with happy flowers and insects with minimal effort come spring.
