Grass growing upside down?

Question

Is it possible for grass to grow upside down? Thinking of laying mats of grass, with grass facing downwards, on top of a perforated metal sheet. Will the grass continue to grow? Or will it stop growing, because the gravity is opposite of what it´s used with? Hope somebody can help!

Answer 1

I would think it is more of orientation to light than the impact of gravity. If the light comes from below you may have some success. Watering would be tricky as the water would go down towards the blades instead of staying in the root ball. You might try using an expandable agricultural polymer in the soil to hold the water. I’d start some grass in a groundcover tray with sone netting to hold the grass in place, allowing it to grow through the turf netting. Then attach the the metal sheeting. The metal may get too hot for the root zone. Sounds like a fun thing to try. Post back if you have success.
