How to create wildflower seed bombs

Beneficial insects including bees and butterflies love the nectar that wildflowers provide – and with this in mind you could get your kids to help you make some seed bombs, which will be a magnet for pollinators and provide lashings of colour next year.

Garden expert and podcaster Michael Perry (aka Mr Plant Geek), explains: “Seed bombs – or tsuchi dango (‘earth dumplings’) as they were known in ancient Japan – are the perfect way for gardeners of all levels to include wildflowers in their gardens.

“The hard clay protects the precious seeds from any wind or hungry wildlife, and together with the compost, provides them with all the nutrients they need to grow wild.”

Here, Mr Perry offers a step-by-step guide to seed bomb success.

“Once you’ve made them, all you need to do is just throw them and sow them,” he says.

1. What you need

Ingredients:

  • 5 handfuls of peat-free compost
  • 4 handfuls of air-dry red clay
  • 1 handful of native wildflower seeds
  • a splash of water

You’ll also need:

  • a mixing bowl
  • a baking tray
  • greaseproof paper

2. Place the ingredients in a bowl and mix them together

Place the compost, clay and seeds in a large bowl, ready to mix. Use your hands to combine all of the ingredients together, adding a splash of water if needed. You’re aiming for a thick but mouldable consistency. The seed bombs need to hold their shape, so try to avoid adding too much water at once.

“If you’re making this with your children or grandchildren, this is the mucky part they’ll love the most. It’s a bit like making mud pies,” he enthuses.

3. Roll them into balls

“Once you’ve combined all your ingredients, roll the mixture into little balls. The size is up to you – these ones are slightly larger, but you can make them smaller, similar to the size of a golf ball, if you’d prefer to scatter them over a larger area.”

4. Leave them to dry

Place your seed bombs on greaseproof paper, ready to dry. Use a baking tray if you plan to move them elsewhere. Leave for four to five days, or until they’ve completely hardened (check for soggy bottoms). Placing them out in the sun, or near a source of warmth, will speed up the drying process.

5. Sow, sow, sow!

Now it’s time to sow your seed bombs. Wildflowers will bloom well in containers, window boxes and borders – anywhere with a splash of sunshine. Place them just below the surface of the soil for best results. Then let nature do its thing.

Wildflower seeds are best sown in autumn, while the soil is still soft and warm. This gives them time to develop strong roots before the frost kicks in, resulting in bigger, healthier plants.

“By spring, and throughout the summer, you’ll be treated to a sumptuous display of wildflowers, including cornflowers, chamomile and common poppies to name a few. You’ll also be doing your part to help protect our buzzing friends and their pollinating pals by providing them with the nectar nourishment they need to thrive,” he says.
