Product Description carrat-down

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 carrat-down

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.

Aftercare carrat-down

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

Can i apply this now and then in a couple of weeks scarify and overseed? or would you recommend to scarify first before using this and overseeding?
Question by: simon on 9 Mar 2021, 15:31
Hi Simon

I would suggest you scarify before applying the fertiliser.
When you apply the fertiliser make sure that it is well watered and fully dissolved before sowing seeds.

How long should o wait between applying the pre-seed fertiliser and sowing new seeds? Thanks
Question by: Dan on 23 Apr 2021, 22:29
Hi Dan

Once the fertiliser has been fully dissolved then it is safe to seed.
Answer by: Roisin McCann on 27 Apr 2021, 07:30

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, 16:24
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

Hello, I’m about to kill the weeds and moss in my lawn and overseed and topdress, is this the correct fertiliser to use during? Thank you
Question by: Daniel on 28 Feb 2021, 02:54
Hi Daniel. No we would not recommend using this product to treat your weeds.

However we do have Feed, Weed and Moss Killer product. It works over the course of two weeks to eradicate weeds and moss - where it is particularly prevalent patches will appear and these will need seeded. It will also feed your lawn and make any existing grass very green and lush. It is a granular fertiliser and needs to be watered in after application.
Answer by: Roisin McCann on 1 Mar 2021, 09:07
Hi, can I use this straight after overseeding? Thank you
Question by: Daniel Cameron on 9 Mar 2021, 01:26
Hi Daniel

We recommend that this product is applied prior to sowing. If applied after I would leave it a few days and make sure that the granules are well watered and fully dissolved.
Answer by: Roisin McCann on 9 Mar 2021, 08:15
I have a Scotts evergreen drop spreader - do you know what the settings would be to get the correct dosing for fertiliser prior to over seeding

Question by: Steven on 13 Apr 2024, 17:29
Unfortunately, I don't have the information for that spreader as we do not sell any. If you try to contact the manufacturer of that spreder they should be able to advise on a setting that would be suitable.

When can I use this quick release pre seed
Question by: Tony on 29 May 2022, 12:30
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.

I'm looking to sow my seeds in late sept early oct, once I've appiled the QUICK RELEASE: Pre - Seed Fertiliser and givin it a good watering can i add the seeds straight away?
Question by: Chris on 16 Sept 2020, 10:08
Hi Chris

Thank you for your enquiry.
Once applied and watered until the granules have fully dissolved you can seed straight away.
Answer by: Roisin McCann on 24 Sept 2020, 14:07
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, 09:23
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.
