Product Description

Our Feed, Weed & Mosskiller is the complete fertiliser solution for a tired and weathered lawn that is being held hostage by weeds and moss! This fertiliser acts in three noticeable steps – moss shrinks and dies off and can be easily raked away and weeds quickly disappear by being killed at the root. Existing grass becomes vibrantly and instantly green, revealing areas ready for reseeding.

After application, we recommend waiting 2 weeks before planning to seed. This ensures your fertiliser has adequate time to take effect and complete its full process – killing off moss and weeds, and sufficiently feeding your lawn. Patches will appear where moss and weeds have been killed off, these areas will require reseeding. This product should only be used on an established lawn (6 months + old)

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.

How effective would this be at treating clover?
Question by: Alan on 8 Mar 2021, 08:47
Hi Alan

The Feed, Weed & Mosskiller will treat White Clover (Trifolium Repens)
Answer by: Roisin McCann on 8 Mar 2021, 11:58

How often can this product be used, is there any minimum period between applications.

Question by: Nigel Evans on 1 Jul 2021, 14:21
Hi Nig

The feed and moss killing aspect takes up to two weeks to take effect and the fertiliser will continue to feed the garden for up to six weeks. Once this time is up you can reapply if required.

Keeping pets and children off the lawn is easy.My concern is other wildlife.My garden is visited by hedgehogs and wood mice,not to mention the blackbirds probing for worms.What would be your advice using this product under these circumstances ?
Question by: Michael on 5 Mar 2021, 20:06
Hi Michael

We would always advise that you air on the side of caution, if you are not confident that the wildlife won't be around for the 2 weeks then I would not apply.

Hi I bought the bag of this in March, used it to great effect but have loads left. I have since used pre seed fertiliser having over seeded. I don’t intend to put a separate spring summer fertiliser down now but am thinking about what to use in autumn- can this be used now and then throughout autumn / winter for the feed content even though there is little weeds/ moss left? If so What quantity and how often?

Thanks very much
Question by: Steven Stewart on 6 Jul 2021, 07:39
Hi Steven

Whilst it does have a fertiliser, this wouldn't be a product we would recommend applying if you are not planning on treating weeds or moss. All our fertilisers will last up to 4 years, if stored in a sealed bag somewhere cool and dry, so you can use it again. The composition of the winter fertilisers is designed to strengthen and harden the grass whilst protecting against winter borne diseases.

Hello, I recently scarified and then over-seeded 2 months and 3 weeks ago with your seed. Would it be possible to apply this material now to support new growth, greenery and reduce weeds (there’s a lot) please?
Question by: Chris Dowland on 8 Jun 2021, 23:56
Hi Chris,

We do not recommend applying this product to new lawns. Anything younger than 4 months then do not apply it, some of the chemicals in the mix can damage younger grass. If it is around 4 the month mark.

I do hope this gives you some clarification. Any other questions just let me know.

i have a few weeds in my lawn, am i to late to apply weed killer or should i wait to next year?
Question by: Mark Waters on 1 Oct 2020, 18:21
Hi Mark

Our Feed, Weed and Mosskiller can be applied at anytime of year and is not a seasonal product.

Answer by: Roisin McCann on 2 Oct 2020, 09:06
I have used about half of this before over seeding an existing lawn this October. Can I use this again and if so, when should I use it?
Question by: anthony on 7 Oct 2020, 16:31
Hi Anthony

We do not recommend using this product on any lawns younger than 6 months. If stored in a cool dry place it will keep and can be used next year if needed when the lawn is well established.

Hi I have fruit trees growing in my lawn (apples and pears), I'm concerned about the product ending up in the fruit, is it safe to use?
Question by: Greg on 8 Sept 2022, 10:27
Hi Greg, thank you for your question. Our Feed, Weed and Mosskiller, if applied around trees, will not cause adverse effects to trees and specifically the fruit in the trees.

Will the weed killer part of this product kill Parsley piert .
Question by: Oliver seyfried on 8 Nov 2022, 09:43
Hi Ollie, thanks for the question. The Feed, Weed & Mosskiller can help eradicate parsely piert. However, this can be a tricky one to remove and may need a few applications. It is worth noting that this particular product is a 6 week fertiliser, so can only be reapplied after this time has passed.
