Review: Excellent Seed - First, I don't ever leave reviews, no matter how good or bad the product is. Secondly, I've never had luck planting seed. I didn't feel like buying 1200 square feet of sod, so I gave this product a try. Within the first week, seed started to germinate. Within in two weeks, excellent growth was happening. By week 5, almost all 1200 square feet we filled in. Deep green and lush lawn. the one thing I did, was new top soil and law fertilizer. Combine all three, and you will get excellent results.

I even took some seed and placed it in a seedling tray and it didn't germinate either. I attempted to reach out to the company twice prior to posting the negative review to provide them with an opportunity for a response/explanation and never received a response. **Q: Would this grass be good in Missouri** A: I have no reason to believe why it should not grow there. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent Seed *by J***N on 13 September 2024* First, I don't ever leave reviews, no matter how good or bad the product is.
