We recently built a house and are starting from ground zero with establishing a lawn. We would like Zenith Zoysia In our front yard. We purchased seed back in May from super sod But none of it came up. We suspect since we watered, it rained, we added appropriate nutrients to the soil, that the seed was bad. Could you please tell me the best place you would recommend to purchase Zenith Zia seed? What place or places do you trust the most to sell the best quality? Thank you!
