Keys to Successful Grass Seeding

Proper planning and attention to detail is crucial when establishing a stand of grass. Establishment requirements differ for perennial grasses compared to annual grain crops. See these five key points below to promote successful grass seeding success.

1. Seeding dates

   1. Soil moisture and temperature are key points to pay attention to when planting grass. Cool season grasses can be planted when temperatures are cooler and day lengths are shorter. Warm season grasses need warmer temperatures and longer day in order to grow.

      1. Cool season grasses are best planted in Spring (April-May), Late Summer (July-August) or Late fall as a dormant planting (end of October or later).

      2. Warm season grasses are best planted in Late spring (mid May-late June). Late summer or late fall/dormant planting is not recommended for optimal establishment.

2. Seedbed preparation

   1. A firm and competition free seedbed

   2. Seedbed should be firm but not too firm

      1. an adult footprint should only be slightly visible on the prepared bed prior to seeding

   3. Seed planting depth is important

      1. most species should be planted at a shallow depth of 1/4 to 1/2 inch deep

      2. larger seeds can be planted up to 1 inch deep

   4.  Tilled or no-tilled seedbeds are acceptable as long as weeds are controlled

      1. weeds can be controlled with tillage and/or herbicide before or just after seeding

   5. Companion crops are typically not recommended for grass seedings due to the competition for water and light

   6. Residue can greatly affect seeding depths and soil contact

      1. residue should be harrowed to spread extra chaff and straw

      2. late summer and dormant seedings, however, are best planted into stubble

3. Seed placement

   1. Equipment should provide proper seed depth, uniform seeding rate and good seed to soil contact

   2. Drills should be calibrated to monitor seeding rate

4. Seed Quality

   1. Seeds should be tested for purity and germination

5. Weed Control

   1. Competitive weeds can be controlled mechanically by clipping or chemically controlled

      1. Dense clippings should be removed from the seeded area

   2. Weeds should be controlled with herbicides before they reach 4" tall
