Methinks this should've operated on seed-planting rather than sun-starving, but a cute idea non-the-less. Here's designer Romain Duclos:
You have no time to garden...
"Jardin à la Francaise" is an innovative concept allowing people to personalize a corner of greenery according to their mood. This kit gives an elegant and refined style to your garden in a few days, whether it is for an event, a reception or simply to imagine a short-lived decoration.
Place synthetic field elements on the grass by following a figure on the guide, or invent one of your own!
Leave from 10 to 12 days, removeâ€¦and here is your printed motif field! Your garden is personalized and will stay with this creation for approximately fifteen days.
