1. Can I sow grass seed now? 2. What is the best soil amendment for clay?

My lawn was dug up due to having a sewer line replaced. I have a huge area of nothing but clay. What can I do?

Yes, you can plant now. You'll have to baby it all summer, watering during dry periods even after you have it established and are mowing. If it gets really hot, some may die back and you may have to overseed in the fall.

Use an organic soil amendment of some composted produce, such as LeafGro.

If the area isn't too large, consider sod.

Here's a good page about starting successful lawns (and we have much more on lawns, too): https://extension.umd.edu/hgic/topics/lawn-renovation-and-overseeding

Get a soil test done before you start, so you can correct pH, which be vital, and work the lime and any fertilizer needed into the soil while you're working in the soil amendments: https://extension.umd.edu/hgic/topics/soil-testing
