Product Description

Quick Release: Pre-Seed boosts grass seed germination rate while accelerating and enhancing growth over the course of six weeks for fast establishment of newly sown lawns and overseeded areas. This pre-seed fertiliser includes added magnesium and iron to significantly improve your lawn’s ability to absorb nutrients and ensure your new grass is green and healthy.

Apply this fertiliser before sowing your seed, and then water it until the granules have dissolved fully. Its micro granules dissolve quickly, ensuring the nutrients sink deeply and quickly into your soil.

Quick Release: Pre-Seed is rich in nitrogen, phosphate and potassium, giving your seedlings the best foundation for growth:

  • Nitrogen (N) gives your lawn its lush green colouring and enhances its growth for fast establishment
  • Phosphate (P) helps build up the grass’s root system and improves its root-to-soil contact
  • Potassium (K) strengthens your grass to build immunity and tolerance to grass diseases and drought
  • Magnesium (Mg) helps grass process phosphate quicker and more effectively
  • Iron (Fe) strengthens your grass against mosses and weeds and gives it a bright green, healthy colour

Key Benefits

  • Provides the perfect foundations in which to grow a lavish green lawn
  • It is a phosphorous-rich fertiliser that prepares your soil to ensure new seedlings grow better
  • The added magnesium helps your new grass absorb phosphate and other key nutrients while significantly enhancing photosynthesis
  • Additional iron in this fertiliser helps your new grass grow super green and strengthens it against moss
  • The micro granules dissolve fast and spread nutrients quickly across your soil
  • It can be used from March to September

Please note this fertiliser can scorch your grass blades, so remember to water it off or apply just before the rain is due. Avoid application during very hot periods. We recommend applying on cooler evenings or overcast days. For more information on all things fertiliser, read our Fertiliser FAQs.

Usage Guide

Apply our fertiliser at the recommended rate by hand when wearing a glove or by using a spreader
Water the fertiliser in until it dissolves
Keep kids and pets away from the lawn during application and until the granules dissolve
Remove / water off any footwear you were wearing during the application of the fertiliser to avoid any risk of damage to newly laid patios / stone flag flooring

Not watering your fertiliser in can potentially scorch existing grass or delay the benefits of the fertiliser.If after watering the fertiliser does not disappear and dissolve off the surface, water until you cannot see the granules.

You can apply this fertiliser any time you plan to overseed or sow a new lawn, recommended sowing times are March - September. For a general lawn feed that promotes greeness, you may wish to consider our Slow Release: Spring / Summer or Quick Release: Spring / Summer fertiliser.

Use March to September
Spreading Rate 70g per m2
Watering This fertiliser MUST be watered in - granules should not be visible after application if watered sufficiently.


If you are planning to overseed or sow a new lawn from scratch, you can do so once the fertiliser granules have dissolved

Product Questions

Product Questions

I already use the product as recommended. However we still have about 1/3 of the bag. Can i spread it over the lawn? It is over 7weeks from seeding. Can this fertiliser “damage” da lawn ( of course i will watering well)? What proportion i have to use?
Question by: Bobby on 14 May 2023, 06:32
Hi Bobby, thanks very much for your question.

Yes, you can continue to use this on the lawn throughout the summer. Just as long as you allow the 6 week window between applications and follow the recommended spreading rate - 70g per m2 and it is well watered. It will also last up to 4 years if stored somewhere cool and dry, so you can continue to use it next year if you wish.

Hi what number should I put my evergreen drop spreader at when putting your preseed fertiliser down thanks Chris
Question by: Chris Connell on 15 Mar 2023, 12:48
Thank you for your question

We would recommend setting Setting 12.5 x 3 passes for the QUICK RELEASE: Pre - Seed Fertiliser. Please note that the recommended setting is for guidance only and we can not be 100% accurate as we did not manufacture the spreader. Always be cautious not to apply too much product and if you are unsure it is best to work with a lower setting to avoid the risk of damage.

Hello - I've completely re-seeded a large part of my lawn with your superstar back-lawn seed and your pre-seed fertiliser (fully dissolved before seeding). How soon after can I add your slow release fertiliser to this area, to further strengthen the grass? While most is long and lush, there are patches where it is thin and has started yellowing at the ends, and would like to give it the best chance to withstand the winter. Thanks!
Question by: Alex C on 5 Dec 2022, 15:36
Hi, we would recommend waiting until the garden is fully established and at least six weeks after applying the Pre Seed before applying another fertiliser. We would also suggest holding off on applying anything to the garden during December and January as the ground is usually frozen.

I’m about to use your fertiliser based on 70g per m2. Can you advise me on what setting to use on my Scott’s spreader.
Thank you
Question by: James on 29 Sept 2022, 12:25
Hi James, what model is the spreader?
Answer by: Roisin McCann on 29 Sept 2022, 13:33
It's September and I'm about to renovate my lawn, scarifying and overseeding. Is this OK to use prior to overseeding at this time of year, or would I be better with the Autumn/Winter quick release? I also have fruit trees in my lawn, is it OK to use?
Question by: Greg on 8 Sept 2022, 10:23
Hi Greg, thank you for your question.

You can apply all of our fertilisers before or after seeding, except for our QUICK RELEASE: Pre-Seed fertiliser, along with our Feed, Weed and Moss Killer. Both of these products should both be used before seeding.

If applying fertiliser before seeding, you can sow the grass seed once the fertiliser granules have fully dissolved, unlike our Weed killer, where you should wait two weeks for the treatment to take effect.

If applying fertiliser after seeding, it would be fine to use it 6 weeks after seeding when your new grass is hitting blade heights of 5-7cm and has had its first mow. Our Feed, Weed and Moss killer should not be applied to lawns under six months old.

Our fertilisers, if used around trees, should not cause any adverse effects to the trees and the fruit in the trees.

When can I use this quick release pre seed
Question by: Tony on 29 May 2022, 13:30
Hi, thank you for your question!

We would advise applying our QUICK RELEASE: Pre-Seed Fertiliser prior to seeding.

We would also suggest mowing your lawn before using this product. It is a granular fertiliser, so it will need to be watered in after application.
Answer by: Helen McGale on 30 May 2022, 09:31
Hi, I have been watering this for 4 days, it’s had a LOT of water and is still not dissolved. I have raked it in a bit so it’s hidden under the soil now more or less. Is this ok to now put grass seed down? It just won’t dissolve.

Question by: Nicola sjekel on 20 Apr 2022, 13:44
Hi, thank you for your question.

Our fertilisers can take up to 10 days to fully dissolve, and we would suggest continuing to water your lawn.

We would also advise holding off sowing grass seed until the fertiliser is fully dissolved.

How often can I reapply this pre-seed fertiliser?
Question by: Terrance on 2 Apr 2022, 10:38
Thank you for your question! Our Quick Release: Pre-Seed fertilisers provide six weeks of feed, and once the feed duration is up, you can feed your lawn again.

is your pre seed fertiliser still usable after a years storage
Question by: gary warwick on 20 Mar 2022, 21:32
Hi, thanks for your question.

Yes, our fertiliser will keep for up to four years if they have been stored in a cool dry place!
Answer by: Helen McGale on 21 Mar 2022, 09:43

I used the quick release: pre seed fertiliser on 24th September, a week before sowing new seed (Impress: clay master) on 1st October and watered the fertiliser in as advised.

Two weeks since sowing and the grass is growing well.

Since the bag of fertiliser is 20kg and my lawn is only 8m x 8m, I have a good deal of fertiliser left over from the initial application. Can I use this fertiliser once the lawn is established? If so, how soon after seeding should I use it?

If not, which fertiliser would you recommend and when would be the best time to apply it?

Thank you!

Question by: Tom on 14 Oct 2021, 17:24
Hi Tom, whilst the fertiliser can be reused, ideally in the colder months we would recommend our SLOW RELEASE: Autumn/Winter Fertiliser. It will harden the lawn and provide the ultimate protection during the colder months. It gives four months of continuous feed, and although it is less intensive than a quick release it is a more balanced feed. This will take you through to the Spring when you would then consider our Spring/Summer range or you could apply The Re Seed for a quick boost.

All our fertilisers will keep for up to four years if stored in a cool dry place
