Essentially, wildflowers are native plants that grow and thrive in the wild, without human intervention.

Planting wildflowers in your garden can bring a lot of beauty and vibrancy to your space whilst also playing a crucial role in supporting local ecosystems and pollinators.


Natural Beauty

Transform your outdoor space into a vibrant canvas of colours and shapes.

Low Maintenance

Once established, wildflowers generally require less upkeep compared to traditional gardens.

Pollinator Paradise

Invite bees, butterflies, and other pollinators into your garden, contributing to a healthier environment.

Ecological Balance

Support native wildlife by providing them with food and habitat.


Contribute to biodiversity conservation by growing plants naturally adapted to your region.


It’s important to choose the right wildflower seeds for your climate and soil conditions. Wildflower seeds are an investment in the beauty and health of your garden. Our seed selection offers you a range of seeds to suit your local environment.

Once you've measured the area you intend to plant, a general rule of thumb is that sowing 100% wildflowers would require 3 grams/m2 and for a 80% grass/20% wildflower mix it would be 5 grams/m2.


Timing is important when it comes to successful wildflower planting. Wildflowers should ideally be sown in April/May or late August/early September, avoiding peak summer weather or the colder frosty winter months.

Ideally look for a weather window without heavy rain or extreme heat, as these conditions could hinder seed establishment.


The groundwork you lay determines the success of your wildflower patch. Just as with any DIY project, proper preparation is key.

The timing of planting matters; ideally, you want to avoid frost or extreme dryness. Spring and autumn are usually optimal, with rain aiding seed establishment before the challenges of summer heat or winter frost. Nevertheless, wildflowers can be sown year-round with consideration for weather conditions.

Step 1: Select the site

Choose a location that receives a good amount of sunlight, with well-drained soil. Wildflowers generally prefer soil that is not excessively wet or prone to waterlogging.

Step 2: Remove existing vegetation

Clear the area of existing grass, weeds, and other vegetation. You can do this by mowing, digging, or using an herbicide. If you choose to use an herbicide, follow the manufacturer's instructions carefully and consider using an environmentally friendly option.

Step 3 : Soil Testing

Test the soil to assess its pH and nutrient levels. Many wildflowers prefer slightly acidic to neutral soil. Amend the soil as needed to achieve the desired pH level and fertility. Lime can be added to raise pH, while sulphur can lower it. Incorporate organic matter, such as compost, to improve soil structure and fertility.

Step 4: Till the Soil

Use a garden tiller or a spade to loosen the top few inches of soil. This helps create a suitable seedbed for the wildflowers. Remove any rocks or debris from the soil during this process.

Step 5:Rake the Soil

After tilling, rake the soil to create a smooth and level surface. This will make it easier to sow the wildflower seeds evenly.

Step 6: Seed Sowing

Sow the wildflower seeds according to the recommended seeding rate for the specific mix or species you've chosen. You can mix the seeds with fine sand or vermiculite to help distribute them more evenly.

For smaller seeds, lightly rake them into the soil to ensure good seed-to-soil contact. Larger seeds can be pressed into the soil with a board or roller.

Step 7: Watering

Water the seeded area gently but thoroughly immediately after planting to settle the seeds into the soil. Use a fine mist or a soaker hose to avoid washing the seeds away.

Step 8: Maintenance

Monitor the area regularly for weeds and remove them promptly, as they can compete with the wildflowers for nutrients and space. Keep the soil consistently moist but not waterlogged until the wildflowers are established. After that, many native wildflowers are drought-tolerant and may not require frequent watering.



We recommend cutting your established wildflower area down to approximately 15 cm, three key times per year:

  • May/June (early Summer)
  • August (late Summer)
  • Late September/October

On the final cut of the season, you could choose to mow the meadow fully back, so it looks neat through the winter, just be sure to remove any cuttings to reduce soil fertility.


While wildflowers are low maintenance, they do require a bit of support in the initial stages to ensure weeds don’t over power them. Just routinely remove any nettles, docks and thistles before they set seed to ensure your seedlings thrive in peace instead.


The easiest way to trim your meadows down to size is with a strimmer if it’s not too large an area. Be sure to check the area for wildlife such as hedgehogs that could be hiding away.

At the end of the season, you could use a lawn mower once you’ve cut it down to a manageable size
