      Saltire Mixtures        

The proportion of varieties and species used in every Saltire Mixture has been determined after the most careful consideration of farming conditions in Scotland. The duration of a grass mixture is mainly dependent on two factors:

  • The component varieties
  • The management regime.


Saltire 5        


Saltire 5Recommended for silage and grazing

Saltire 5 is a highly versatile dual purpose mixture, which will produce two large cuts of silage and quality grazing.


Saltire 6

Saltire 6 is Watson’s most popular Saltire Mixture.

Contains persistent varieties ensuring good yields for cutting and grazing over many years. – See more at:

      Grass Rejuvenation         

A full reseed is not always possible due to factors such as stocking pressures or thin top soil not permitting deep cultivation. For thin or badly poached pastures, pasture rejuvenation should be considered a viable alternative to a complete reseed.

Successful pasture rejuvenation occurs when competition from the existing sward is minimal, these conditions occur during early spring before the grass is growing too quickly or after second cut silage/early autumn when the soil temperature is still high.

First you need to assess the condition of the sward before deciding how to improve it. We at Barrett Agri are Watson Seeds seed specialist and will be happy to visit you and advise a course of action.


  • Subject to adequate temperature, moisture is the single most important element required for germination.
  • Check soil fertility status. pH should be 6-6.5, this will certainly support better clover growth.
  • Discuss with your seed specialist an appropriate mixture for sowing.
  • Depending on strategy adopted, mow, graze or spray existing sward to minimise trash in the seedbed and competition for new seed.
  • Pay close attention to pest control – slugs can often attack new grasses so slug pellets may need to be considered. Frit fly and leatherjacks often build up on old pastures.
  • Post drilling husbandry – rolling is usually advisable to ensure the seed is covered and to lock in moisture, other than when using a drill with an inverted-T slot system. Stock should be kept out of the field whilst the seedlings establish – especially sheep which are selective grazers.
  • Do not apply fertiliser 3-4 weeks pre-rejuvenation and only apply fertiliser post seeding once the new seedlings are visible and will compete with the existing sward when fertiliser is applied.
  • Do not try to rejuvenate silage swards at the beginning of the season. The young seedlings will be shaded out under a tall crop. Rejuvenation of any conservation grass is best carried out later in the season and grazed post sowing, when interplant competition is less severe from the existing mature plants.
  • Check for soil structure problems and compaction as this may have been a reason for the need for rejuvenation in the first place. If compaction is an issue subsoiling must be carried out.
