Seed Bombs

Seed bombs offer a unique way to distribute beneficial wildflowers to an area. 

The idea driving Radical Roots is to place in the hands every individual the power to contribute to restoring native plants throughout Canada. 

One small action has huge benefits. 

Helping bee and butterfly populations, adding biodiversity, promoting soil conditions, making our neighbourhoods and world a better place. 

Unlike annual or pre established plants, native wildflower seeds take time. Most species will not flower/bloom the first year. We make the seeds bombs with a ratio (generally 50/50) of wildflowers that have the ability to flower in the first year verse ones that do not. Which is why we only use perennial wildflowers.

Growing a native garden may not be what you’re used to when gardening. In most cases the first year will look like green plants. 

But don't fret, the seeds are working their magic. Buying Radical Roots seed bombs is a pledge to conservation, not just the aesthetic of having flowers.  

The pledge to put forth native wildflowers to help preserve pollinator species, which in turn helps to conserve native ecosystems. 

This isn't instant gratification. 

This is patience

This is growth year after year. 

This is sustainability for the future.   

Planting can be done early Spring or in Autumn.

Planting during Summer months pose a risk of the seed bombs not germinating until the following year. While the seeds will remain viable you may not see any growth again until the following year.

Seed bombs protect the seeds inside by encasing them with clay and worm compost. This mixture protects the seeds from drying out, washing away or being eaten by birds or squirrels. Rain or water releases the seed allowing the seed to take root. Often times the seed will grow when the conditions are best, this may seem like the seed isn't growing within a certain time frame but rest assured the seed will only grow when experiences the best time (warm, moist soil). 

Seed bombs are meant to work in areas with preexisting vegetation but will grow better is a spot is cleared of grass prior to planting. 

With native species some types need to experience stratification before germinating and growing.  

Seed bombs require little maintenance. 

For Spring planting: After last frost place on top of soil, preferable bare soil, just before rain or watering. Water thoroughly or keep soaked. Seeds can take 4-8 weeks before sprouting  

Fall planting: Before snow falls place onto the soil or at level with the ground. Cover with leaves for extra protection. 

While a ball full of seeds may seem appetizing for squirrels or other rodents, we add a natural spice to make it less so. We believe this is the best way to keep squirrels from eating our seed bombs. Although we cannot control squirrels with a spicy palate ;-) we can help keep your seed bombs safe and ready to bloom.

Having a ragweed allergy, you may know that flower in the daisy family can cause some reactions. Which is why our No Brainer Container blend has no daisy family flowers and is be safe to be grown while living with this allergy.
