How do I calculate how much grass seed I need?

  • Measure the area of your lawn or field in square metres (measuring the width by the length will give the area)
  • Multiply the area by the sowing rate given for each mix (in grams per square metre), always using the highest sowing rate if you are creating a lawn on bare earth
  • Divide the results by 1000 to give the number of kilograms required

For Example: For a lawn area 20 metres by 25 metres.Calculation is: 20m (length) x 25m (width) x 50g (sowing rate) ÷ 1000 = 25.00 kg

How long does grass seed take to germinate?

In a well prepared seedbed with adequate soil moisture during long, warm and overcast days (and with near equally warm nights) germination may be as quick as 4 or 5 days however, the more limited these conditions are the longer germination will take, even with regular irrigation.

In extended spells of hot, sunny weather, times of low rainfall or prolonged cold conditions with short days, germination can take many weeks and very little may happen until more favourable day length, temperatures and/or rainfall persist.

What is certified grass seed?

Only certified seeds have been tested and comply with the European Standards for seed purity and germination.

From the fera (part of DEFRA) website: “Seed Certification is a quality assurance process which ensures that seeds are sufficiently pure, healthy, viable and correctly labelled. Seeds marketing is regulated and, for most species, only seeds which have been certified may be sold.”

How long does grass seed store for and where’s the best place to store it?

If stored in a dry ambient area, grass seed should keep well for 2- 3 years without a significant drop in viability. Therefore, the best place to store grass seed is in a cool, dry shed or outbuilding

Are there any tips for a great lawn?

  • Prepare the seed bed well
  • Sow your lawn using high quality lawn seed best suited to your lifestyle and requirements. Re-seed annually and repair bare patches
  • Mow your lawn regularly and avoid cutting too low
  • Water your lawn frequently in dry conditions
  • Feed lawn with nitrogen rich fertiliser in Spring/Summer and a balanced fertiliser in autumn
  • Rake out old grass in the Spring and Autumn
  • On heavy soils, aerate your lawn in Spring and Autumn
  • Control weeds and moss ASAP
  • Trim lawn edges for a good finished effect.

What’s the best way of cutting the lawn?

  • The ideal cutting height for the average lawn should be about 3/4 “
  • Cut the lawn once a week from Spring to early Autumn, but if you can cut it more often you will be rewarded with thicker, denser grass
  • Invest in a good mower with a grass collecting box
  • Look to produce Zebra stripes (the dark and light stripes), this will hide any imperfections and will give the lawn a quality look!

What is the guide to Paddock Reseeding?

  • Check soil nutrient status: Target soil pH is 6-7. Phosphate and potash indices should be 2
  • Drainage: Correct any drainage problems before reseeding
  • Seedbed and sowing: Ground should be worked to a fine tilth, Soil temperatures should be a minimum of 5°C before sowing, Sow during the growing season (March – September), Seed depth should not exceed 15mm (1/2 inch), Roll before and after sowing for optimum consolidation
  • Weed control: Spray out weeds prior to seedbed preparation. Control any emerging weeds at an early stage of development
  • Pest control: Assess the risk of pests such as wireworm, frit fly larvae and leatherjackets. Seek professional advice on pesticide use to protect new seedlings
  • First grazing: Allow sward height to reach 5-6 inches (125-150mm) before grazing to ensure a good root system is established.
