40 bottle stand being assembled |
Our sand and seed bottles are a mix of sand and an 80/20 blend of rye grass and chewing fescue seed. You can read about the chewing fescue here. Some places mix in a mulch, some places dye the sand green and some don't even put in seed. Every different way can be effective, but one thing is common; if not used regularly, grass will grow inside the bottles and clog them up.
