Lawn fertiliser options?

bbari

Guys - sorry for posting in an old thread, I couldn't find answer anywhere, google didn't help either. may be I'm not searching the correct term.

I am advised to use 10-10-20 as a fertiliser in my lawn. Where can I buy it around Dublin-15 ? Garden size is 100 Sq M - what quantity should I buy ?

Do you really want to use 10-10-20?
Would 0-10-20 not be better?
(The 10 units N will make your grass grow a lot, meaning it will need cutting cutting more often, not something I would have thought you'd want in a lawn?)

As for where in Dublin, sorry, no idea...

Whites agri in lusk i.d say, garden centre would have small amounts!

i'm a newbie in this area and don't much hence looking for advice on what is best. Garden is relatively new, only seeded in last May (newly built house). The grass isn't so thick and I can see the ground between the grass. I don't mind mowing once/twice a week. Does 10-10-20 make you to mow every 2nd day ?

10-10-20 on the spring, 0-10-20 or Any of the 0's in the autumn.

Little and often with the fertiliser is key. Spread at 50kg/acre every 6 weeks starting in late spring and across the summer till last cut, then apply the 0 feet to strengthen roots over the winter. The first figure is the nitrogen content, you don't want nitrogen applied over the autumn/winter as it just grows a mop of grass to be dealt with come cutting season.

You'll find an online area converter to work out the area for you.

I'd be a little worried if a lawn laid last may wasn't good by the end of the growing season if the seedbed was good and the topsoil was good quality.
I wonder was there enough seed used in the first place? Did it come up thick and fairly even?

I assume you stopped mowing at the back end of the year and let a bit of grass cover build up for the winter?

Are you on good ground do you know?

Thank you. Garden size is 103 M2 so I need 1KG. Probably bag of 50KG be too much!

Grass isn't thick at all, you can see the ground thru the grass.
Sorry - didn't know I should have stopped mowing. I mowed on new year eve and mowed last weekend again! another mistake - mowed to the shortest level as I thought its better
Not sure if the ground is good or not. Should I also buy some grass seed when I'm buying 10-10-20 ?

Here's picture of the garden. Kids put some bread for birds, thats why you see few birds there.

It not so bad looking at that pic. Yeah, you should have finished mowing last back end. There was exceptional growth though in many areas since then. Don't mow it any more till spring.
I think it's thick enough that it'll tiller out without need for more seed. A dressing of fert as outlined above I think will go a long way to helping it.

We use the proper lawn fertiliser a couple time a year and find it very good...there's stuff in it to control moss and weeds.
If you do decide on lawn fertiliser, make sure moss killer and weed killer is stated on the bag, otherwise your fertiliser will be encouraging the weeds to cmpete with the grass
If you're collecting the grass you're taking nutrients off with every bit of grass and it has to be replaced,
The recommended rate per sq mtr is written on the bag of lawn fertiliser and if it was mine I'd give it one application in April and another in june/july.
If it doesn't respond, it's probably because there wasn't any clay put in by the builder, some only used rubble in the gardens.

Is 10.10.20 not considered as a Proper Lawn Fertiliser? Sorry if I'm asking a stupid question!

It's a fertiliser compound used in agriculture.. there are specialised garden ferta like rangler said that inhibit moss/weed development as well as supplying nutrients to the soil

Op, a shake of lime wouldn't go amiss on that lawn either. You can buy a 50kg bag of granulated lime for around a tenner. It would help to release nutrients that would be locked up in the soil.

_Brian

What the lads are referring to is known as a "weed and feed" product as it will kill weeds and feed the lawn. They're expensive if there is much lawn to do and a newly laid lawn should have very little weeds.

Lime would indeed be a good job.

As rangler said, every cut strips feed from the ground that should be replaced.

As for cutting height. Start high in spring, move down over the summer and then finish the season high again.

Last few years I've used 18-6-12 on the lawn three times during the season and it worked well, cutting no more than every 4/5 days. I don't bother with an autumn feed though it is advised.

Thank you larthehar for suggesting Whites in Lusk, Just off the phone,

10-10-20 is €20 for the bag of 50KG.

The guy on the phone was very helpful and he suggested OSMO Pro 1 (15-3-8 + 2Mg + 1FE) and he said its better product for lawn. That comes in 25KG and cost €23.

They do sell Garnulated Lime too.

_Brian - you are right, there is none/very little weeds. I bought a small bottle of "All in One" in Woodies for €25, used in late October (realise now it was too late). It didn't make any difference.

Do you think OSMO Pro1 is better than 10.10.20? I know It is double the price but surely I don't need 50KG...

Mooooo

The 10.10.20 is probably better. The numbers stand for the n (nitrogen) p (phosphorus) and k (potassium) in that order. It would be no harm to put out more p and k to give the roots a better chance and a greener lawn. N will push growth. If you keep the bag in a very dry place and cover it after taking a bit it may last a bit. +1 on the lime as well.

Nothing wrong with 10-10-20, as you see there's other things in the OSMO, -the 1FE is probably to control moss which thrives in some lawns. 10-10-20 is a good general purpose feriliser, but if your lawn is prone to moss it will encourage it. As you see by the numbers, there's more nutrients in 10 -10 20 so it probably is the fertiliser to use on a poverty stricken lawn and worry about the weeds and moss when you solve the problem in the grass

Thank you guys.
I will go for 10.10.20. The lime you mentioned is €5 per 100M2. Should i get it just for one use ?

Yes get the lime. If you were to only get either lime or fertilizer, get the lime.

May be handier, a bigger bag of lime may be harder to keep spreadable and dry. At the end of the year you could mulch the grass instead of collecting it for the last few cuts and spread some lime then again before winter

I will get both. I was asking if I should get just enough for one use only.

Only get enough for 1 application and see how it goes. Also mulch the grass back onto the lawn. The soil could be low in organic matter and mulching the grass back onto the lawn will help boost soil fertility

bbari

Great. I'll get 50KG bag of 10.10.20, small amount of Lime for once of use and will leave the grass back on the lawn. I got manual push lawnmower so i'll just remove the basket. I'll share Before/After pics once the fertilisers have actioned - can't wait! Thanks a million folks.

I have a feeling that grassbox will be going back on.

Don't go too hectic with the fertiliser as the grass will be up over the walls

bbari

Looking at the grass I feel it ll never be green, never mind going over the walls! I will go easy with the fertiliser - promise!

And if it applied too heavy it cam burn the grass, so little and often.

On the subject of collecting the grass cuttings,
I never collect them. I cut it in peak growing season about every 5 days, if it got ahead of me ( holidays or the like) I'd take a cut and maybe take it off to get back to grips with the growth.

I have a mulcher mower which doesn't even have the option of a grass box, works grand here but if there's children here, which isn't very often (TG ) they're very efficient at transporting the grass around the house on their feet.

bbari

I picked the 10.10.20 and Granulated Lime on Saturday. Can I use either of these on my mint plants ?

_Brian

10:10:20 is a good general fertiliser to use all round the garden, grass, hedges, Veg, everything.

bbari

is it ok to use the fertiliser now or do I need to wait for another while and do i need to cut the grass before ?

_Brian

Out it out now if your confident you'll get mowing it.
Putting out fertiliser, growing a mop of grass that can't be mown is a bad thing.

No need to mow before, but as above he carefuk you don't get caught.

Little and often, just like mowing.
