Spring Reseeding Checklist 2026

Reseeding can seem like a big investment, but if the job is done well you will reap the benefits many years after the initial outlay.

9 Steps To Reseeding

Reseeding with modern grass varieties can increase grass production by up to 3t/ha. In addition to increased grass growth, new grass increases grass quality and utilization and is more efficient in terms of nitrogen fertilizer use. This extra, high quality forage ultimately increases farm productivity through higher animal output per hectare compared to old pasture. Following our spring reseeding checklist will help ensure you get the best value from your reseed by producing more tons of quality grass, improving grass utilisation on your farm and making your business more profitable.

1. Identify paddocks that need reseeding based on

Lower than average yield
High weed burden
Poor response to fertiliser
Poor grazeout

2. Consider your system

Do you need a grazing mix, a silage mix or a dual purpose mix? There are loads of grass mixtures and varieties to choose from and each has different qualities that make them more suited to particular kinds of management. Look for mixtures that use varieties with the traits that your system requires - Grazing or Cutting?

3. Ensure adequate soil fertility

Low pH means poor nutrient availability for grass and can reduce clover establishment while low P and K will lead to poor root development and reduce grass yield.

4. Spray off the old sward

Allow at least 10 days for the old grass to die off. Not giving chemicals time to work or not applying the correct rates is a major issue on farm.

5. Prepare a fine, firm, seedbed

If tilling ground ensure there are no clods of old sward or air pockets. Don’t sow seed deeper than 1cm.

6. Roll, Roll, Roll

Always roll the seedbed after sowing. If possible even roll the seedbed before sowing seed. This extra roll will greatly increase germination rate and improve the chances of success.

7. Weed Control

Be vigilant in the 6 weeks post-sowing. Check reseeds regularly and take action with appropriate herbicide as soon as possible if there is any sign of a weed problem.

8. Graze

New reseeds should be ready to graze after at least 6 weeks or when plants pass the ‘pull test’. The first grazing is critical to establishing a thick healthy sward of grass. Use sheep or young stock where possible to avoid damage. Continue to graze low covers for the first 2 to 3 rotations.

9. Feed to yield

Modern grass varieties are high quality, high performance machines and therefore need fuel to perform to the best of their ability. Regular applications of N, P & K fertiliser is essential for optimal grass growth and quality that will persist for many years.
