Ten Tips to Ensure Healthy Forage for Horses

DSC_1130_horses_grazing_webEarly spring is the ideal time to over-seed pastures. After a long, wet winter your pastures are going to need some TLC, including over-seeding, to get them back in shape. Here are ten tips for sound land management that will help ensure your horse has grazing come summer.


Here are some tips for pasture over-seeding:

  • Walk fields as early in spring as possible.  This is the best way to see where there has been winterkill, mold, bare spots and dirt tunnels made by field mice while underneath the snow.
  • Pick the right seed for your soil. Orchard grass does well on most soils. Timothy does better in damper, heavier soils. Brome does OK on sandy soils and it’s very drought tolerant.  Alfalfa is also drought tolerant, but is difficult to over-seed because it will not grow within a certain radius of another alfalfa plant.
  • Buying seed by the pound from an actual forage dealer is the best source for seed.  When you buy it individually by the pound you get just that seed without filler grasses.
  • If you buy bagged pasture/hay seed, understand the language of a seed tag. The percentage of a certain seed by the weight is important. Because some seeds are very small and light, 20% of the seed in a mix could actually result in more like 40% of your stand. Be wary of hay mix blends that say *VNS*. This stands for “variety not stated” and could mean any type of seed is included.
  • While you can use a seeder, including a hand seeder or even a fertilizer spreader, hand broadcasting tends to work best. That way you can control how much goes where: more in bare spots and less or none where there is a thick turf.
  • Make sure if seed is treated to wear plastic gloves and to wash clothes after seeding.
  • Pay attention to the wind.  It can be difficult to over-seed if it’s extremely windy.  A little bit of wind, however, can actually help you broadcast the seed.
  • Do not over-seed on the snow if you have problems with wildlife like birds and deer. They will eat the seed.  Watch for flocks of birds in your fields after you over-seed.  If they become a problem, scare them off using deterrents like a scarecrow or by making a loud noise.
  • Keep a pasture journal where you can make notes about when you over-seeded, which pastures were seeded and what seed you used.
  • Keep horses off over-seeded fields for 6-8 weeks.  If they are really small pastures you may want to keep the field out of rotation for one season.
