Green Roofs and Crimson Clover - Two Weeks and Growing

Green Roof Crimson Clover at 2 Weeks
Green Roof Crimson Clover at 5 Days
Update of the green roof crimson clover trials.

Two weeks since seed was sown.

The young plants are thick and developing quickly, spreading tiny branches and leaves out across the roof.

Eli and I discussed the importance today of using green manure crops - or nitrogen fixing crops - as a best management practice to supplement or hopefully replace chemical fertilizers on green roofs.

Clover makes a great pollinator plant when blooming, provides habitat, prevents erosion, fixes nitrogen and carbon, produces oxygen and adds streaks of green across the roof.

As always, email with with questions and happy green roofing.
