The question can lead to one of two different answers. If you are wanting to build a fence to enclose an area, that is one answer; if you are interested in developing grass in the pasture and have a viable stand before you start to use it, that is another answer. You should contact your local Cooperative Extension office to get advice on the species of grasses and legumes that are most suited to your area. The Extension office can also help you submit a soil sample for analysis so that you can fertilize appropriately to establish grass. If you have broodmares, you will want to avoid tall fescue that is infected with endophyte. There are tall fescue varieties that have a novel endophyte that helps with plant hardiness but does not cause problems with broodmares. Your county Extension agent should be able to help with this. What is currently there? Do you need to control weeds, remove an old infected fescue stand, or are you starting from old crop land? Again you can get help from your agent on the establishment of a pasture mix that will be suited for your area. This fact sheet on Establishing and Managing Horse Pastures will provide additional information.
