I got 15 of these and 15 of the sunny sheets of flowers and after removing all of the grass from a part of my backyard i installed these and staggered them. Just remember to weight down the sheets with like 1/8th of dirt so it doesn't blow away!
Very easy to prepare! Plants are growing.
Laid it down in a sunny spot and added some soil and water and growing so quickly. Not sure what surprises I'll see yet, but can't wait to see.
