Product Description

Quick Release: Spring/Summer is a fast-acting lawn fertiliser which gives your lawn a nutrient boost to bring it back to life after harsh winter weather. Its mini granules dissolve quickly, delivering a feed rich in nitrogen with an even balance of phosphate and potassium to promote healthy growth and provide you with greener grass.

You can apply two fertiliser applications of Quick Release: Spring/Summer each summer. We recommend using it once in spring in April / May and once in early July. This will give your lawn a quick boost to enhance its growth and will continue to feed it over the course of 6-weeks. Water the fertiliser after applying it to immediately dissolve its Mini granules and see the benefits of growth within a few days.

  • 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

Key Benefits:

  • A fast-acting spring/summer fertiliser to feed your lawn quickly
  • Nitrogen-rich lawn food that promotes immediate healthy growth
  • Mini granules dissolve quickly into the soil
  • 6-week intensive nitrogen-rich grass food
  • Apply in spring/summer to bring your garden back to life

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.

Mixture Breakdown

NPK 11.5.5 Mini Granule

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 use this fertiliser any time you plan to do overseed or sow a new lawn. For a general lawn feed that promotes greeness for a longer period of time or will protect your lawn going into winter, you may wish to consider our Slow Release: Spring / Summer or Slow Release: Autumn / Winter fertilisers.

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


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

Hi - do I need to wait any days after mowing before spreading this fertiliser? Also, how long do I need to wait after before my next mow? Thanks.
Question by: Peter Ward on 10 Oct 2023, 15:15

Question by: Shelley on 7 Aug 2023, 09:29
Thank you for your question.

This is a granular fertiliser and will need some watering until fully dissolved. We recommend keeping any pets of the lawn until the granules have dissolved but once they are dissolved it is safe to let them back out.

Question by: Bob on 7 Jun 2023, 12:44
Thank you for your question.

The length of time can depend on a number of factors - how often or how long it is watered/weather etc but generally speaking it can take few days of watering until all the granules are dissolved. To help speed it up, we suggest applying the fertiliser when rain is forecast.

Using quick release spring fertiliser , or slow release spring fertiliser ,
Do I need to keep my dogs off the treated area while granules have not dissolved ? Is it safe for them ? Or should they be totally excluded of the area ?
Question by: Monique on 2 Apr 2023, 12:38
Hi, Thank you for your question. Once you apply our fertiliser, you should keep your pets away from the area and water the granules until they fully dissolve. When the granules have disappeared into the soil, your pets can return to playing on your lawn!

I have just used the spring summer fertiliser on my new soil, how long until it dissolves? Then I can seed?
Question by: Alex Bungey on 30 Jul 2022, 05:26
Hi Alex, thanks for the question! Once applied, you should water your fertiliser until it fully dissolves and you can no longer see the granules. I would also recommend waiting for the fertiliser to run its 6-week course before seeding your lawn.
Answer by: Ben Agnew on 1 Aug 2022, 11:05
I over seeded my lawn last august and it was nice and green. Used the pre seed fertiliser and followed up with your simply seed.

However this spring it started to turn yellow in lots of patches. I applied some of the quick release pre seed and it turned nice, thick green lawn but couple months later gone back to the dry yellow straw like lawn in most places. Not sure if I need to scarify and oversees or apply another type of fertiliser?

I only used the pre seed fertiliser as I purchased couple bags from you previously and had some left over. Guessing I need some summer feed but not sure if it should be quick or slow release?
Question by: D on 7 Jul 2022, 21:05
Hi, thank you for your question.

Yes, it would be fine to use up your QUICK RELEASE: Pre Seed fertiliser.

All of our QUICK RELEASE fertilisers provided 6 weeks of feed, whilst our SLOW RELEASE fertilisers provide 14-16 weeks of feed. Once the feed duration is up, you can feed your lawn again.

There are many reasons for yellow patches on your lawn, and it may be due to a lack of nitrogen, pet urine or common garden diseases. We have a blog post on our website which might be of interest to you: https://thegrasspeople.com/whats-going-lawn/

I have also included our step-by-step guide on how to overseed an existing lawn below:

● Remove any dead grass, weeds or moss by scarifying/raking the area
● Rake the area enough so that the soil is loose and not compact
● Sow the seed at our recommended rate of 35g per m2, by using a seed spreader or your hand
● Rake the seed in after sowing so that the seed is in amongst the soil
● Firm down by foot or by using a roller to improve seed-to-soil contact
● Water the just-sown seed well

I have some new seed to sew on fresh soil but only need less than 1kg of pre-seed. Could i use this as a pre-seed fertiliser and then through out the year as i wouldn't need a full bag of pre-seed or do i need pre-seed first and then this? Thank you
Question by: rosie china on 20 Apr 2022, 14:37
Hi, thank you for your question. It would be fine to use our Quick Release: Spring/Summer Fertiliser on your soil, which will help feed your soil!

Hi my lawn is roughly 9mts x 9mts would a 20kg be big enough
Question by: David Wilkins on 29 Mar 2022, 08:31
Hi, I have used our Grass Seed Calculator, and for a lawn of this size, you would need approx. 5.67kg of fertiliser per each use.

Our fertiliser will keep for up to four years if stored in a cool, dry place!
Answer by: Helen McGale on 29 Mar 2022, 11:39
I have a pretty compacted clay lawn and we're obviously just coming out of a wet and cold winter. Do I need to scarify the lawn before fertilising - or is that only before seeding?
Question by: Will on 28 Feb 2022, 12:06
Hi Will,
There's a few things you can do to ensure a successful overseeding, especially with clay soils. Our blog on this will help point you in the right direction; https://thegrasspeople.com/get-best-clay-soils/.
