I am planning on moving my horse from Austin, TX to Colorado Springs, CO. The pasture we are moving to isn't fertilized and the current owners don't fertilize the land. They let the grass just grow when it does and don't help it along. I was wondering if it would be smart to plant a different kind of grass, leave it like it is, or fertilize the already existing grass-if there is any...Please let me know your opinion; and if I should plant new grass, what kind it should be. Thank you!
