LeaStrain Grass Seed

Why Leastrain Grass Seed??

  • Quality mixtures
  • Designed with the end user in mind
  • Established and trusted brand. (you know exactly what’s in every bag of seed)
  • Access to the very latest in grass seed technology
  • High levels of customer support
  • Long term supplier relationship

Species Summary

  • Early Perennial only for early bite or early first cut silage but not in late areas
  • Intermediate and Late Perennials best suited to most farm situations
  • Late Perennials very dense and good for grazing
  • Hybrid ryegrass is one of the grasses of the future and much better than Italian
  • Festuloliums (Ryegrass Plus) for difficult, stressful situations and longer seasons
  • Timothy great grass for cool wet conditions particularly for bulk on beef and sheep farms and where hay is the main fodder
  • Cocksfoot only in drought conditions
  • White clover for nitrogen and feed value but leaf size to suit purpose
  • Red clover for high yielding short term cutting mixtures and rapid N fixation


SPECIES in more detail:


  • Present in all species of Ryegrass
  • Perennial
  • Italian
  • Hybrid
  • Different genetic makeup to Diploids (twice as many chromosomes)
  • Large seed and aggressive establishment
  • Bigger plants (They always look better)
  • Broader leaves which have a higher moisture content
  • Slightly higher yielding
  • Less dense than diploids with more upright growth with fewer tillers
  • Deep rooting and better suited to dry conditions
  • High sugar content and so are very palatable and good for silage

Italian Ryegrass

  • Short lived but high yielding
  • 2 production years
  • Good early spring, late summer and autumn growth
  • Relatively late heading (same as Intermediate Perennials)
  • Combines early bite and leafy first cut
  • Relatively poor forage quality

Hybrid Ryegrass

  • Maximum 3 production years
  • Cross between Italian and Perennial Ryegrass
  • Combines the advantages of Italian with the benefits of Perennial
  • Italian benefits
  • high yield
  • good early spring and autumn growth
  • Perennial benefits
  • winter hardiness and persistency
  • forage quality


  • Greater stress tolerances than a Hybrid, Italian or Perennial Ryegrass
  • Improved disease resistance
  • Better persistency
  • Varieties include:
  • Becva Short Term Italian Type
  • Perun Italian Type
  • Perseus Italian Type
  • Lofa Hybrid Type
  • Hi-Past Perennial Type
  • Fojtan Perennial Type –Brand new grazing type!!!
  • Hykor Fescue Type

Early Perennial Ryegrass

  • Heading dates – 6 May to 16 May
  • Start spring growth early in the year (about 2 weeks earlier than Intermediate and Late Perennials)
  • Good for early bite for sheep
  • Good for early silage cuts
  • Heads quickly after an early graze
  • Bad for late silage cuts (heads too early)
  • Bad in late areas / high altitude (head early with no bulk)

Intermediate Perennial Ryegrass

  • Heading dates -18 May to 31 May
  • Slower to start growing in early spring than Early Perennials
  • Similar annual yields
  • Similar first cut yields but 2 weeks later
  • Suits most farms except where early bite is required
  • Makes up the biggest proportion of cutting mixtures
  • One of the most important groups of grass seed 

Late Perennial Ryegrass

  • Heading dates in -30 May to 15 June
  • Slower to start growing in early spring than Intermediate Perennials and much slower than Early Perennials
  • Similar annual yields
  • Dense prostrate growth giving good sward density
  • Particularly good for long term grazing
  • One of the most important groups of grass seed


  • Very winter hardy
  • Thrives under cold and wet conditions
  • Good early spring growth
  • Relatively late heading 13 to 26 June (same as Late Perennials)
  • High yielding
  • Very palatable but poorer forage quality than Ryegrass
  • Very good for producing bulk for beef and sheep particularly in later areas and for hay making

White Clover

  • Very palatable and animals eat more of a higher quality feed and do better as a result
  • Deep rooting with creeping growth habit (stolon’s)
  • Nitrogen fixing root nodules can fix up to 160 units N per acre per year
  • Poor competitor with grass as it is sensitive to shading
  • Performs well in drought situations and in mid summer through to autumn
  • Classified into 3 categories according to leaf size
  • Small leaved = grazing
  • Medium leaved = dual purpose
  • Large leaved = cutting
  • Optimum pH 5.8 –6.5 and relatively high demand for P & K
  • Does not like permanently wet conditions

Red Clover

  • Relatively large seeds and aggressive establishment
  • Very high yielding with erect growth habit
  • Deep rooting from tap root
  • Nitrogen fixing root nodules contribute more quickly than in white clover
  • Very palatable, high protein and mineral content
  • Primarily for cutting and lacks persistence under hard grazing
  • Short lived 2 –3 years
  • Relatively low in water soluble carbohydrate (grass sugars), so is best grown with high sugar varieties and species to help silage fermentation
  • Oestrogen problem for breeding animals. It is best to avoid grazing with breeding sheep for 6 weeks prior to and 6 weeks after tupping

Like Germination there is a minimum purity standard set for grass seed certification.

The standard still allows for large amounts of grassland weeds to be planted when a reseed takes place.

DLF ensure that Leastrain mixture purity far in exceeds the minimum standards required for seed certification.
