Quick Guide to Buying Lawn Fertiliser
Which is the right lawn fertiliser for me?
Lawnsmith lawn fertilisers are blended to give the lawn the correct amount of nutrients over a period of time;
- One Feed per Annum: If you're a reluctant gardener you can get a years feeding done in one go with Extra-LONG very slow release lawn feed. It will provide an essential level of nutrients to keep your lawn in good shape from Spring into Autumn
- Two to Three Feeds per Annum: For hobby gardeners where a little more involvement and control may be desired to maintain excellent colour and health. Use seasonal slow release fertilisers in Spring & Summer plus an Autumn Feed for an optimal nutrient level
- Advanced Feed Program: For the enthusiast, you can add to the above by feeding with liquid fertiliser every 4 to 6 weeks during the best growing conditions to meet your and your lawns requirements
Whichever way you go, any lawn feed is far better than no lawn feed!
What's so important about clay or sandy soil?
Your lawn will benefit whichever fertiliser you use; it's just that lawns on sandy soil need a little bit more of everything than those on clay or dark organic soils. If you're unsure which to choose go for the one suited to sandy soil or try our simple soil tests if you want to determine which soil you have.
Child & Pet Safe Fertiliser....
Unlike grass ‘weed and feed’ products, Lawnsmith® Granular Fertilisers do not contain pesticides or weed killers. Though the bag of bulk material should be stored safely away from children and pets, the lawn is safe for use by children, wildlife and all dometic pets including rabbits, guinea pigs, ducks and hens immediately after application. If our soluble fertiliser is used then it would be a sensible precaution to keep grazing pets and fowl off until after the third mowing.
‘No Scorch’ Fertiliser with no ‘Watering In’...
Lawnsmith® Extra-LONG, Spring & Summer and Autumn fertilisers have a high safety margin and will not burn or scorch if applied when some moisture is present in the surface soil. This means not having to worry about rain, weather forecasts or watering in!
Easy to Apply without causing stripes...
Because Lawnsmith® Fertiliser does not contain weed killer you can use a rotary or broadcast spreader. This means faster, easier application with absolutely NO stripes!
What is Turf Hardening?
Some fertiliser elements, normally iron and potassium, actually harden the grass (sometimes called winterizing) and help protect the delicate grass membranes from the cold and occasional winter diseases. Therefore, all autumn and winter fertilisers should contain extra amounts of one or both for a reliable green winter lawn.
Great Value...
Ever wondered why one bag of fertiliser costs £20 and the next one costs £40? It’s all in those ‘NPK’ numbers on the bag. For a rough guide try this:
- a 10 kilo bag of NPK 10-2-4 has 10+2+4 = 16 x 10 kilos = 160 units of fertiliser. If it costs £20 that’s 12.5 pence per unit.
- a 10 kilo bag of Lawnsmith Extra-LONG 29-6-12 has NPK 29+6+12 = 47 x 10 kilos = 470 units. If it costs £37 that’s 8 pence a unit – a fair bit cheaper with 3 times as much content for 3 times longer feeding!
..and if you want to KILL LAWN WEEDS easily...
Then do what ALL turf professionals do – use a liquid weed killer. See our Quick guide to buying Weed Killer.
