Centipede grass is probably the most common type you'll see in east Hawaii, I have it, and all my neighbors, grows well in cinder. Broadcast the seed, cover with a sprinkling of peat moss. There is a grass called seashore paspalum that is smooth and velvety, seldom ever needs mowing, but is slow to establish and I believe only available as plugs, not seed.

Thanks Leilaniguy! I would like to check out seashore paspalum? Where can I find this in Hilo?

I have another question. My front yard has the same cinder but I noticed that it has this black plastic underneath. Can I plant grass on top of it or should i remove the plastic covering underneath first? Mahalo for your help.

I recall there is a lot of it at Richardson Beach Park on Kalanianiole St. and I know it grows along the Red Rd. out at Opihikao. You might check at Garden exchange or Farmers exchange for starts. I don't know about growing over the plastic, sounds like it might be a hassle to remove.

Mahalo for the information. I will go and check out those places. Removing the plastic under the gravel in a big front yard is a big problem. I was hoping I could just leave it.
