- Rotational grazing moves stock between paddocks so each gets time to regrow.
- As a rough guide for perennial ryegrass swards, start grazing at around 8–10 cm and move on when it is grazed down to about 4–5 cm.
- Grass grows fastest in late spring and slows in summer dry spells and late autumn — plan for the dip.
- Rest periods of a few weeks in spring lengthen to much more in slow-growth periods.
These figures vary with species mix and conditions — treat them as a starting point and adjust to what you see.
