Where to Use

Existing lawns – to over-seed
Bare soil  – to establish new lawns

How to Use

Best Conditions:
Lawn seed grows best when the soil temperature is consistently around 10—18°C. If conditions stray out of this range, time and rate of germination can be negatively impacted

How to Sow a New Lawn

1. Prepare the soil by clearing away any debris and weeds

2. Dig over the soil, breaking down any lumps and tread the soil to firm it again. Level with a rake

3. Shake the box to mix up the seeds. Sprinkle in 2 passes at right angles to each other at rate of 30g/sq. m

4. Lightly rake into the surface

How to Thicken an Existing Lawn

1. Remove any weeds. Mow the lawn closely. If the ground is compacted aerate using a garden fork

2. Spread Westland Lawn and Turf Dressing to fill any shallow holes and to level-out the surface

3. Shake the box to mix up the seeds. Sprinkle in 2 passes at right angles to each other at rate of 25g/sq. m

4. Lightly rake into the surface

After Sowing

  • Lightly firm the ground by walking over it or use a roller. This will press the seed into the soil.
  • Water thoroughly using a fine-rose watering can or sprinkler. Take care not to wash the seeds away
  • Water daily until established and in very hot conditions water late in the day once the sun has gone down. It is better to water thoroughly once rather than several times lightly
  • Mow for the first time when grass is 5-8cm high. Gradually lower the cutting height to about 2.5cm. After 8 weeks we recommend feeding with Aftercut Ultra Green Plus.

 

Recommended Lawn Feeds

The overseeding of your existing lawn is an essential part of your annual lawn maintenance. All lawns are affected by the specific growing environment. This includes their level of use and general weather conditions. As a result of these conditions, its key to understand the basic principles of overseeding. Its also important to choose the right  seed mix to achieve a greener and healthier lawn.

Overseeding achieves:

  • To  infill damaged, bare or thin patches, as well as worn areas to achieve a greater thickness
  • All of our lawn seed is pantone matched. So it does not matter if you have used a previous seed product. The colour will be the same – overseeding will improve the colour of the lawn overall
  • Reduce weeds and moss

When should I overseed my lawn:

The best time to do this is either in spring or autumn or both. Germination can take between 7 and 21 days so you will require the ideal conditions these seasons will bring.

Choosing the right seed:

How to overseed your lawn

  • Mow your lawn to approx 25mm.
  • Use a spring tine rake to break up and remove the layer of dead matted grass (thatch). If the depth opf the thatch is quite dense use a scaryfing rake, as this will ensure the seed make contact with the soil allowing it to germinate
  • Using a garden fork or aerator to spike the lawn at 300mm intervals
  • If your lawn has not been fed in the last 4 months we recommend feeding the lawn before overseeding. Your lawn can then be overseeded 3 to 4 days after applying  lawn fertiliser. However, please note you will usually need to wait about 4 weeks after applying a feed, weed & moss killer. (Check the instructions on the product for this.)
  • Sow the seed evenly across the lawn
  • Our range of seed can be mixed with  lawn seeding soil and applied to the lawn jointly. This will save a bit of time and effort working the topdressing and seed into the surface
  • The seeded area must now be kept moist. Therefore, water your lawn after 2 or 3 days if no rain has fallen.
  • Specific bare patches can be reseeded without treating the whole lawn. Apply the same procedure as above
  • To protect specific areas from birds consider covering with netting or garden fleece. This should be removed when new shoots start to come through the soil
  • Try to keep traffic on your freshly overseeded lawn to a minimum for 7 to 21 days
  • Raise mowing heights to approximately 50mm for the initial 2 or 3 cuts, then reduce down to 25mm over the next 2 or 3 cuts

Tips

  • 4-5 days before sowing a new lawn, lightly rake Westland Growmore into the soil
  • When preparing to sow, if the soil is dry water it thoroughly the day before and leave to soak in overnight
  • The top of the soil should be dry with moist soil just below the surface on the day of sowing
  • For the best results apply Gro-sure® Lawn Seeding Soil with any Gro-sure® lawn seed

General Advice

  • Children and pets need not be excluded from the treated areas
  • Store in a cool, frost-free place away from children, pets and foodstuffs
  • Use contents within season of purchase
  • Contents may settle in transit
