Sowing your wildflower seeds

Wildflower seeds are designed to be sewn onto the surface of your green roof substrate. Do not cover them or mix the seeds in with the growing medium. You should scatter them by hand, aiming for equal distribution across the whole area of your green roof but not until it's levelled and raked to a fine tilth.   

When to plant/sow your wildflower seeds on your green roof?

It is best to sow your wildflower seed in spring or autumn, although they can be sewn all year round as long as there is sufficient moisture (not too much) and it’s not too cold. Our green roof drainage membrane helps avoid water logging that can be problematic.

Our green roof maintenance guide features helpful tips on when a green roof might need watering.

How long do the wildflowers take to grow?

Depending when the seeds are planted you should expect to see growth in the first year however some seeds (especially perennial species) will require frost/thaw action in order to germinate, therefore flowering may be more successful in the second year.
