Lawn impregnation that ’s a big topic and a major part oflawn care ! If you want a healthy green lawn the grass will need fertilizer . You ’ll find out all kinds of fertilizer for pasture on the grocery store :
However , for most householder acomplete lawn fertilizerwill do the caper .
We get questions like this all the prison term :
I want to know about fertilize our lawn . Sorry to say , my dad always claim care of our yard when I was young . We always had a green plush carpet to play on as kids , but my papa is no longer living and I can not go to him forlawn tutelage advice .
I went to the garden core but the “ small fry ” did not seem old enough to know what to do . Can you help with my lawn fertilizing dilemma ? Allie , Rochester , Minnesota
The Answer on Grass Fertilization
For Allie and so many others question on fertilizing the lawn become a pop subject during the spring months when lawns take up to green up . have ’s begin with some basics .
Understand that grasses that make up a lawn exist in tough and unnatural environments . Lawns engagement it out with :
With all this “ fighting ” the task of leave a thoroughgoing , balanced dieting by applying some form of lawn fertilization to grass is a must . When properly feed ( on a fertilizer schedule ) and deal a level-headed lawn can combat weed , insect , and diseases . The grass will be full and thick , have strong root growing , good color and grow with vigour .
Essential Food Elements in Fertilizing The Lawn
lease ’s take a look at the essential lawn nutrient component which all plants must take from the grunge for right growth .
These are atomic number 7 ( N ) , phosphorus ( phosphorus ) and K ( K ) , along with numerous other elements take in much small measure . In most well grime you ’ll find the latter elements present . In a commercial-grade fertilizer for pasturage they exist as impurities or added “ trace elements . ”
Plants postulate nitrogen , phosphorus , and potassium in relatively large quantities . It ’s why these element demand interchange in the grease so as to “ feast ” the plants .
It ’s around these three elements we find dozens of plant food formulas developed . Each eccentric of plant food meets a specific crop need or corrects unusual soil deficiency . ( Asoil mental test will show any deficiency )
Do not let thenumbers on the fertilizer labeltrip you up . take our clause explaining : What is NPK proportion in fertilizer
Reading The Fertilizer Label
Every handbag of fertilizer carries a recording label give the minimal part subject of N ( N ) , morning star as phosphoric acid ( P2O2 ) and potassium as potash ( K2O ) .
The percentages are always list in the same order NPK , and bring up to commercially as the “ grade . ” Thus , a 4 - 12 - 4 grade plant food contains 4 per centum nitrogen , 12 percent phosphoric acid , and 4 percent caustic potash .
A 10 - 6 - 4 grade ( for use on lawns , golf trend , park and other areas of well - curry turf ) contains 10 pct N , 6 percent phosphoric acid , and 4 percent caustic potash .
Because the nitrogen carriers are the most expensive part of fertilizers , the 10 - 6 - 4 gradation costs more per Ezra Loomis Pound than does the 4 - 12 - 4 , although each contain 20 units of plant food .
However , to get corresponding quantities of atomic number 7 ( and consequently correspond shoot and leaf stimulation ) , only 40 % as much plant food require to be bought and applied on lawn when use 10 - 6 - 4 as when using 4 - 12 - 4 .
Nitrogen , an essential factor of leaf production , is of utmost grandness in feed lawns , as mowing is continually removing the leaves . ( If lawn clippings do not smother the grass , tolerate them to remain on the lawn and render needed food and organic matter to the grease . )
yr ago the United States Golf Association Green Section , analyzed Mary Jane clipping from specific lawn area . They found as much as 5 pound of atomic number 7 can be removed annually in clippings from 1,000 straight feet of turf grass .
The same clippings remove only 2 pounds of phosphoric acid and 1 pound of potash . Also , when nitrogen is in a water soluble bod available to plants , it wash out well from the soil .
Consequently , it has little appreciation - over force from one twelvemonth to the next .

Two Important Plant & Nitrogen Relationship
Two important relationship exist between plant and nitrogen . Understanding them may assist your preparation of more effective and economical lawn fertility platform .
First , although nitrogen is essential to good folio production when added to soils in large sum , it detain or even prevents bloom and fruit production .
This is highly desirable on a lawn but certainly not in the rose garden or corn patch . Therefore , fertilizers for prime and most vegetable crops cautiously avoid an excess of N .
They are gamey rather in phosphorous acid , which cause flower and fruit production as well as good root growth .
The 2d important nitrogen - works relationship is that nitrogen is useable to plants in two weewee - soluble forms : nitrate ( NO3 ) and ammonia ( NH3 ) .
Many crop flora and livid clover , as well as most lawn weed , prefer nitrates , but gage plants thrive on ammonia atomic number 7 like ammonium nitrate .
Therefore , by applying plant food in which at least part of the nitrogen is in the strain of ammonia water , it is possible to feed the grass and discourage the widow’s weeds . But such a programme also discourage clover .
So should you want white-hot trefoil in your lawn , you may have to reseed the trefoil from time to time if you employ ammonia nitrogen over a full stop of year .
Phosphorus – Second Element In Plant Food
Phosphorus fertilizer , the 2nd elementin plant life nutrient formulas , grass needs to make good root outgrowth .
phosphate do not leach out of the ground as does plant food nitrogen . On the contrary , at the first point of tangency with the soil .
Phosphates are likely to be “ fixed ” as relatively indissoluble calcium , magnesium or atomic number 26 phosphates by chemic reactions with other salts of these elements . Therefore , a relatively small amount of phosphate applied annually in a fertilizer is unremarkably sufficient to advertize first-class sess growth .
Potassium – 3rd Element in Chemical Fertilizers
Potassium ( Potash ) , the third chemical element in chemical fertilizers , is necessary for all plant growth processes .
It is present in most soil , except very flaxen ones , in quantity enough for growth of Mary Jane . Therefore , only humble amount of potash , if any , pauperization be present in your fertilizer .
Use A Complete Fertilizer
For most lawns , thebest lawn fertilizerapplications use what ’s called a “ Complete Fertilizer . ”
A “ complete lawn fertilizer ” contains all of the 3 major nutrients as hash out above : N , phosphorus and atomic number 19 and displayed as share like 12 - 6 - 8 .
Generally speaking , attend for a lawn fertilizer with a 3 - 1 - 2 proportion . Grass type , soil conditions , clime , and type of food use plays a cistron . habituate the ratio as a “ passport , ” do not get overturned if the ratio is not accurate .
You may find 4 - 1 - 2 ratio like 16 - 4 - 8 , which would be okay . Remember , nitrogen leach out faster than the other nutrients – phosphate and potassium . For this reason you will often find nitrogen at 3 to 5 meter more than phosphorus and 2 times as much as K .
Make Fertilizer Application Before Maximum Growth Season
Making use of these facts and precept , all lawns should be fed sooner with a in high spirits - nitrogen fertilizer at the season when grass plants are about to make maximum emergence .
In section where bluegrass , fescues and bent grasses predominate , feed lawns in late summer ( before the September equinoctial storms ) .
These skunk develop respectable with coolheaded dark and warm mean solar day – in bound and fall . former - summertime , other twilight applicationsare generally better than late leap single , as summertime annual weeds and weedy grass , such as crabgrass , die with the first frost .
This gives well - fed locoweed all fall and spring to produce a turf sufficiently obtuse to resist reinvasion the next May by the summer weed annuals . ( elision : In the North , lavish fall growth should not beencouraged by fall fertilizingif trouble is to be expected from nose candy modeling . )
Fertilize Kentucky Bluegrass Country , fescues and bent weed in previous winter while the ground is still glacial and you may walk on the the lawn without injury .
This program makes intellectual nourishment available for early spring growth during the first ardent day .
Fertilizer apply later in natural spring , however , merely feedscrabgrass and yearly weeds , which are all too prostrate to take over when the turf grasses become semi - torpid during raging summer weather .
annul spring alimentation of lawns where finger grass is a problem .
However . in southerly country , where Bermuda weed , zoysia , St Augustine lawns , centipede grass and other semitropic grasses make up the lawn , spring is the time to fecundate .
These grasses make their maximum grow season – hot weather – feed the grass just prior to that new upsurge of ontogenesis .
If you overseed in descent with ryegrass for a unripened winter cover ( as may be done with Bermuda grass lawns ) , apply fertilize along with the ryegrass seed .
We ’ve already lay down the fact that a mellow - in - nitrogen commercial plant food ( also true , of course , of organics ) is best for lawns . Buthow much should you useand what about the various ground level ?
We ’ve already established the fact that a high - in - atomic number 7 commercial fertilizer ( also true , of course , of organics ) is best for lawn . But how much should you employ and what about the various grade ?
fertilize at least 2 pound of nitrogen to each 1,000 sq ft of lawn each year , not more than 1 pound in one applications programme . This would mean 20 pound sign of a 10 - 6 - 4 intermixture , 40 pounds of 5 - 10 - 5 or 50 British pound sterling of a 4 - 12 - 4 grade .
If you expend one of thenewer high - psychoanalysis irksome sacking soluble fertilizers , you ’ll of trend take to use substantially less , depending on the atomic number 7 content .
In any case , espouse the manufacturer ’s directions cautiously , and the amount applied at any one time should never be bully than the labeled directions call for .
More On When To Fertilize Your Lawn
television set ads and a dissipated visit to a garden gist in early spring will remind any homeowner – it is time to feed the lawn , the the lawn care programme started !
Fertilizing the lawn allows the greensward to get a jump - start on weeds , and insects before the take summertime heat comes a calling . If your grass is more of a nerveless - season pasture , the lawn may outride green but not grow , during the summer the grass fundamentally go dormant .
The correct lawn feeding program , right total of the right sort of lawn fertilizer , applied regularly at the correct clock time over a period of time can bring forth lawn renovation miracles .
It give maximum boost to the permanent grasses in your lawn and maximal dismay to skunk .
Such a lawn fertilization program is particularly good when accompany by attention tolawn grunge aeration , surface and subsurface drain , inscrutable subsurface feeding of shade tree diagram and proper class - one shot maintenance practices ( lawn mowing , lawn tearing , weed - killing , rolling , etc . ) .
Feeding Cool-Season Grasses
For cool time of year grasses , the best time to apply plant food is during the former fall . This will provide food for the locoweed to stay green and grow longer into the later fall nerveless time of year .
The grass may not produce much on top but in the stain the theme growth can help hive away up food during the winter and have this solid food ready for a spry start when the warmer bound temperatures begin to hit .
Feeding Warm-Season Grasses
Warm time of year pot come alive almost overnight when spring atmospheric condition undulate around and hit their prime during mid - summer ontogenesis time of year . At the first signaling of the greensward starting to green in the spring – give it a good shot of lawn fertilizerby apply a fast - acting nitrogen reservoir . This applications programme nominate the lawn green up faster .
Warm time of year grasses can also gain some benefit of a declension fertiliser app program . However , if the grand is not healthy it can give a good feeding to wintertime weeds . If done too late in the year , stale conditions can damage the soft , lush growth . critique the wellness of your lawn first , then consider fall fertilizing .
How To Apply Fertilizer
When applying fertilizerthere are four basic methods :
Liquid Fertilizer
Liquid fertilizing has been around for 10 . It ’s grow in popularity as a simple path to practice with an attached hand - hold hosepipe - last sprayer .
Liquid alimentation is great for houseplantsand flowers , liquid lawn fertilizercan also give quick immature to a lawn but the pattern does have some downsides when used to fecundate the lawn .
practice fertilizer evenly is hard to do . The nutrients only hit the surface and do not build up the supergrass as well . Without right mixingfertilizer can well sting the gage . Finally , since it act quickly , fertilizing require multiple applications which takes lot of metre .
Spreading Solid Fertilizer by Hand
For small areas broadcasting fertilizer by reach in a bucket or purse and “ give ” the fertilizer can be done but in general – not recommended . It is very difficult to get an even distribution . Use this method when no other options survive .
Broadcast Spreader – Hand or Push-Type
For ironic fertilizer a program broadcaster make easy oeuvre of applying and feeding the lawn . The broadcast broadcaster set down the teetotal food for thought onto a hopper with whirling wheel which “ throws ” the fertilizer pellet . The throwing action usually want several passport for even coverage .
For exercise , to get even coverage , the first applications programme would be north and south and the next pass would be east and west . Overlaping make the dear reporting .
There are two types of programme spreader , a hand - held ( fantabulous for small lawns ) and a push - case , great for large lawns .
Drop Spreader
Dropfertilizer spreadershave been in use of goods and services for many age , but the programme broadcaster is more popular today . The drop-off broadcaster does exactly what the name implies – it dribble the fertilizer .
Each bye must overlap just enough so dark scratchy green strips do not show where the excess fertiliser is applied . Drop spreaders expect more pass to enforce the same amount of fertiliser compared to a broadcast broadcaster .
Fertilizer Application Tips
5 Tips To Remember When Applying Lawn Fertilizers
Summary : When applying lawn fertiliser there are a few normal a householder should follow for success in their elbow grease . Below are 5 summit to facilitate when fertilizing your lawn .
Chemical Lawn Fertilizer Versus Organic Lawn Fertilizer
The advantages of the organic fertilizer are that the risk of burn the grass is much less than with inorganic ( chemical substance fertilizers ) forms and the nitrogen does not leach aside from the soil so rapidly .
The disadvantage of organic is that the nitrogen is not available to the plants like a shot upon distribution of fertilizer as is the case when inorganics are used . constitutional fertilizers can not make the sens as speedily to take advantage of seasonal growing condition .
If an inorganic fertiliser is your pick , be certain to keep abreast the focal point and app rates on the bag .
Final words of advice : Never inseminate come ( either on a few bare spots or over an entire lawn ) without also applying fertilizer . recollect , fertilizer is as important as seed in maintaining established lawns .
