Making a meadow in Autumn
The Gourmet Gardener
Tara Kate Linnane
It's October and there is a shift in the air. The gentle remnants of summer have now given way to autumnal crispness. I fully embrace autumn and all it has to offer in the garden - the seasonal colours giving a final show before winter, harvesting apples, pears and autumn berries, and most importantly, the opportunity to plan and sow for an early summer wildflower meadow.
Wildflower meadows or patches can be vibrant or mellow, and feel busy or quiet. The outcome depends on the type of seeds sown and whether or not you have a specific purpose in mind. Annual wildflowers can be used in smaller areas, along fences or in pots for a colourful summer display. Native perennial wildflowers are not suitable for pots but work well for larger areas supporting biodiversity.
Annual wildflowers
When you think of a picturesque wildflower meadow, you typically imagine a field of beautiful red poppies and pockets of bright blue cornflowers with sparks of marigold yellow. Of course, these species of wildflower attract plenty of pollinators and have a great visual impact in the first year. However, these wildflowers are annuals. This means the seeds are sown once and they flower heavily the first year. In order for the colour to return the following year, they must have the opportunity to self-seed. In reality, this leads to far less impact in the second and third years.
Perennial wildflowers
To create a meadow with longevity but with a more subtle visual impact, a native perennial mix is in order. A perennial flower species will live for multiple years, but most do not flower the same year they are sown. Once established, they will provide sustainable summer displays for pollinators to feast on year after year.
Perennial wildflowers require less maintenance than annual wildflowers. They look more natural and are considered a better approach for long-term biodiversity. Some widely recognised species include buttercups, oxeye daisies, wild carrot and selfheal. The colours are more muted but they are excellent for attracting pollinators nonetheless. There is one secret ingredient needed to ensure a wildflower meadow is maintained for years to come - yellow rattle. This species of wildflower suppresses the growth of grass in the same area and allows the wildflowers to become well established over time, providing a pollinator haven.
How and when to sow
There are a few notes for sowing a wildflower area. Firstly, clear the area of grass and weeds as these will compete with the flowers. Then spread the wildflower seed mix evenly and according to the instructions from wherever you have purchased the seed (I would recommend using Irish suppliers). The soil does not need to be fertile, seeds will germinate better in poor soil. Finally, rake over and wait until spring, when the meadow magic will unfold.
A wildflower meadow can be sown in spring. However, autumn is the best time to sow as it supports the plants to establish faster and flower earlier in the late spring/early summer.
This mimics nature's cycle, giving the seeds damp and cold conditions over winter to germinate more effectively. It’s also likely that there will be little to no watering involved if the seeds are sown into the ground in autumn.
Pots will have to be watered in the spring as they dry out.
Whimsical wildflowers can be sown on any unused patch of ground in a town or school for the community and pollinators to enjoy. All you need is a pack of seeds and some patience.
