Regrassing for a Productive Farm

by Euan Seymour

Regrassing is a vital part of pasture management on New Zealand farms. Whether you’re looking to improve pasture quality, recover from drought or pugging, or introduce new grass species, a well-planned regrassing strategy can boost productivity and animal performance. Here’s what you need to know about regrassing to get the best results.

When to Regrass?

The best time to regrass depends on your region and farm system, but typically:

  • Autumn (March–May) is ideal in most areas as cooler temperatures and consistent moisture help seedlings establish before winter.

  • Spring (August–October) is suitable in areas with mild winters, allowing rapid growth before summer.

Choosing the Right Grass Seed

Selecting the right pasture mix depends on soil type, climate, and intended stock class. Common options include:

  • Perennial ryegrass – A versatile choice with high productivity and persistence.

  • Hybrid or Italian ryegrass – Ideal for short-term pastures with fast establishment.

  • Cocksfoot or tall fescue – Suited for drier regions with deep root systems.

  • Legumes (clover, lucerne) – Improve nitrogen fixation and feed quality.

Preparing the Paddock

Proper paddock preparation is crucial for successful establishment:

  1. Weed and pest control – Eliminate weeds and manage pests like grass grubs before sowing.

  2. Soil testing and fertiliser application – Check pH and nutrient levels, and apply lime or fertiliser as needed.

  3. Cultivation vs. direct drilling – Cultivation provides a clean seedbed, while direct drilling maintains soil structure and moisture.

  4. Rolling and firming – Ensuring good seed-to-soil contact improves germination.

Sowing and Establishment

  • Seed depth and rate – Follow recommended sowing rates and depth (typically 10–15mm for ryegrass).

  • Post-sowing management – Light grazing at the right stage encourages tillering and helps control weeds.

  • Moisture management – Timely rain or irrigation ensures strong establishment.

Maintaining New Pastures

Once established, good management is key:

  • Grazing management – Avoid overgrazing too soon; allow plants to develop strong root systems.

  • Fertiliser application – Support growth with appropriate nutrients.

  • Weed control – Monitor and address weed competition early.

Final Thoughts

Regrassing is an investment in your farm’s future productivity. By choosing the right seed, preparing properly, and managing establishment well, you’ll set your pastures up for long-term success. If you’re considering regrassing, plan ahead and take advantage of the best sowing windows for your region.
