Product Description

Slow Release: Spring/Summer is the complete feed solution for summer in one swift application. This fertiliser once dissolved, disperses throughout your soil in stages, providing it with the nitrogen it needs all summer long. Our Slow Release: Spring/Summer fertiliser strengthens roots of new seedlings to protect them against drought in dry, hot weather. Apply in early spring to see the benefits for the 12 – 16 weeks.

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 12.0.6
2.0% Iron (fe)

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 from March – August. If you are looking for instant results from a fast-acting fertiliser over a shorter period of time, you may wish to consider our QUICK RELEASE: Spring / Summer fertiliser.

Use March to August
Sowing Rate 35 grams per m2
Watering This fertiliser MUST be watered in - granules should not be visible after application if watered in sufficiently.

Aftercare

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

Can you apply in the rain?
Question by: Pete on 7 Mar 2021, 10:45
Hi Pete


Yes you can apply in the rain, the rain helps the fertiliser to dissolve. However you must not rely on it completely and you may need to water to ensure it is fully dissolved.

Hi

I am suffering with red thread on my lawn I have it scarified and aerated annually. I notice you have a winter fertiliser for this but what do i use to control it in spring and summer

Many thanks

Hi Paul

A lack of nitrogen encourages the fungus to take over so you might consider the Quick Release: Spring Summer for faster results. it is a 6-week intensive feed that thickens up the grass and makes it very green and lush.
It can be applied every 6 weeks in spring / summer. Our recommended spreading rate is 70g per m2. It is a granular fertiliser and needs to be watered until fully dissolved - you should mow your lawn before application.

You can then maintain the condition of the lawn throughout the winter with the SLOW RELEASE: Autumn / Winter Fertiliser.

Hi again
Shall I put the fertilizer down first or new grass seed?
Thanks
Question by: Michelle McCabe on 5 May 2021, 08:54
You can do either, apply it prior to sowing or wait until the lawn is established then apply.
If you plan to apply prior to sowing, ensure the product has fully dissolved before you sow the seeds.

Hi,

How long after seeding can I use this fertiliser?

Many thanks
Question by: Peter on 3 Feb 2021, 11:58
Hi Peter

We would recommend that you wait until the lawn is fully established before applying this fertiliser, usually around 6-8 weeks after sowing.

Hi
I'm putting together my lawn maintenance plan for the year and have a problem which how much fertiliser to use and when. The slow release spring / summer fertiliser can be applied in March and lasts 4 months i.e. end June. The Slow release Winter can be applied in August. As there is a gap in July should I re-apply the Spring / Summer in July (assuming it rains) and the Winter in November? OR delay the Spring until April?
Many thanks Ian
Question by: Ian on 5 Feb 2021, 16:49
Hi Ian

I would recommend applying the SLOW RELEASE: Spring Summer in March, taking you through to June, you can then apply again. Hold off on applying the SLOW RELEASE: Autumn Winter until later, in and around October will still be fine. As long as it is down before the frost sets in. I hope this helps.

Is this product pet safe (dog) I have planted child and pet seed what fertiliser is pet safe to go with your seed?
Question by: Lawrence on 25 Apr 2021, 09:14
Hi Lawrence

This is a granular product and will need watered until fully dissolved. Once it has dissolved it is safe to allow pets back on the lawn.
Answer by: Roisin McCann on 27 Apr 2021, 08:36
Hi, I brought your spring/summer fertilizer and shade grass seed a little while ago, with the plan to put the fertilizer down in March and the seed in May. Obviously I've missed that window. When would you now suggest putting both down?
Thanks Michelle
Question by: Michelle McCabe on 3 May 2021, 10:42
Hi Michelle

The grass sowing season is generally from March - September, so there is still time. You can confidently sow grass seed when temperatures are 8-10 degrees and above consistently for at least two weeks with no adverse weather conditions forecast. Always consult a two week forecast prior to sowing.
Answer by: Roisin McCann on 5 May 2021, 08:32
Can the slow release feed be applied more often than every 4 months? Its been a few months since I used the feed and its looking like it could do with another
Question by: Billy on 5 Jun 2022, 10:25
Hi Billy, thank you for your question.

We recommend allowing at least 12 weeks before applying any more of our SLOW RELEASE: Spring/Summer Fertiliser. We would suggest judging whether you feel that your lawn needs more feed, as overfeeding your lawn and giving it too much nutrition can have an impact on your lawn.

Can you offer smaller bags? 20kg is too much for my size lawn. Would save on cost too.
Question by: Scott on 1 Jun 2021, 18:09
Hi Scott

Unfortunately, we only sell fertiliser in 20kg bags however, these can be stored and re-used when required.

Our fertiliser will keep for up to four years if stored in a cool dry place.

This says 12-0-6 NPK - but your fertiliser guide refers to 12-6-6 which seems more suitable for this usage, please can you confirm if this is a typo?
Question by: Parf Daddy on 11 Jul 2022, 20:10
Hi, thank you for your question. 12-0-6 NPK is the most recent up-to-date analysis. One of our fertiliser guides may refer to an old specification. I apologise for any confusion caused!
