Can you grow grass on fabric?

Yes, you can grow grass on fabric. However, you need optimal conditions to do so. Some commercial growers grow seedlings on several types of textiles including burlap and a specially developed non-woven textile called Sure to Grow which is similar to quilt batting. Growers who use textiles as a substrate use hydroponic irrigation systems to deliver complete nutrient solutions to the plants.

In France, plants are grown in geotextiles and installed vertically opn the facades of buildings creating a "green wall". Once again, nutrients are supplied via the irrigation system.
