A seed bomb is a large egg sized blob of soil, flower seeds and a little clay powder if your soil isn’t sticky enough – I also add a bit of chili powder to the mix, as this deters birds from pecking at them to get the seeds. It’s also possible to add in used coffee grounds too to bulk out the mixture.
The theory is you throw these pellets into your garden and they sprout over the summer – it can be hit and miss, and invariably and ironically, works best on poor or gritty soils.
A set of these also make a nice gardening gift, I dry mine in egg boxes, which make a great way to recycle some packaging too.
Using boxes of annual ‘sow & grow’ seed mixes from most discount shops is the cheapest way to create seed bombs – for a finer mix, choose Annual flowering plants, as these need much less care when growing – perennial plant seeds often need a little more nurturing in the early life stages:
Flowers suited to seed bomb mixes are
Ox Eye Daisies
Small 5ltr bag of multipurpose compost, or garden soil, or a mix of the two.
Clay & Chili powder
2 – 3 Boxes of Sow & Grow flower mixes
A little water
Egg Boxes for drying
Taking a handful of damp soil and clay, roll and form an egg-sized ball.
Press this lightly flat, and then cover with a handful of seeds, and chili powder.
Re- form the ball, adding a little moisture if needed, until it holds together.
Place in an old egg box or on kitchen roll to dry.
Once the seed bombs are dry, you can take to your garden, or the streets and perform some direct floral interventions on derelict areas and sites in the city. The garden created by the Limerick City of Culture project on Thomas St in Limerick City is an example of the wildflower mix of planting.
