Palmetto grass is a cultivar of St. Augustine grass. It's known for its deep, vivid green color. It is a nice addition to a yard because of its appearance and soft texture. Another positive characteristic of palmetto grass is that it performs well in sun and shade. Palmetto can withstand temperatures as low as 5 degrees F. Centipede grass is a favorite in areas with less fertile soil. This variety is low maintenance and can withstand similar temperatures as palmetto. Centipede grass does best in full sunlight. Combining the two will ensure that your lawn benefits from the best characteristics of each variety.
Plant the grasses in the full sun. Even though palmetto grass can grow in the shade, centipede grass thrives in direct sun, so choose an appropriate area.
Run a rototiller over the land to loosen the soil. The grass varieties need aeration for root growth and spread. Dig the machine 4 to 6 inches deep.
Remove weeds and debris. Grass seed needs to adhere directly to the soil to germinate. Rocks or sticks will impede this. Rake the plot relatively smooth.
Pour an equal amount of centipede grass seed and palmetto grass seed in a spreader. Use a hand spreader for small lawns and a mechanical spreader for large areas. There is no need for fertilizer before the seed is dispersed.
Broadcast an even amount of seed over the lawn. Walk the spreader back and forth in rows, then switch directions and work perpendicularly. This will ensure that there are no gaps of seeds. Both grass types can share the growing area because they complement each other.
Rake the seeds gently to cover them with the top 1/4 inch of soil. This will keep them in place and encourage germination.
Water the grass seed immediately. Use a hose set on a medium spray. Centipede and palmetto grasses can resist drought but will grow the best if they are watered weekly.
