You can grow a lawn in sand but it will take lots of regular watering. Start with Hewitt’s Sandy grass seed. This is a blend of tall fescue grass that are fine bladed but have a deep root system. Keep the seed constantly moist while it is germinating…NEVER let it dry out, not for a minute. Once it is up and growing, Feed it with our Starter Lawn Food. Keep it well watered all summer and feed it again in September. Don’t mow it any shorter than 4″-5″ this entire summer while it is getting a root system established.
