Anyone who has a garden has likely get word of mulch . It ’s one of the building cylinder block of a salubrious garden and there ’s an almost infinite phone number of things that can be judge as mulch , in particular constitutive mulch .
Organic mulches are raw ground top made from plant - based or beast - based materials . But their benefit go beyond simple skunk control and moisture holding . Organic mulches also stimulate bug , improve soil structure , and release nutrients into the grease as they moulder ( unlike inorganic mulch such as rubber or pea plant gravel , which are primarily used to cover the ground or grace a landscape ) .
If your headspring is spinning from all the options out there , I ’m break down my 12 preferent organic mulch to apply in vegetable gardens , blossom beds , and landscapes ( some of which might even be freely available in your own yard ) .
revealing : If you shop from my article or make a purchase through one of my link , I may meet charge on some of the production I recommend .
Quick tip
To extract the most benefits for your yard , make certain you ’re using not only the correct sort of mulch , but thatyou’re using mulch right .
Compost
Got a compost pile ? Awesome , you ’ve got mulch !
I bed compost is usually used as a soil amendment , but if you have some left over , think about it : it ’s free , it has lading of nutrient , and it ’s full of good microorganisms , worms , and other raw decomposers . you could practice compost as is ; no need to add another mulch layer over it .
If you have a large orbit to cover , buy compost in bulk is a great elbow room to feed and protect the soil at the same meter .
When Iplanted my fruit orchard in Manuel de Falla few years ago ( witness in the ikon above ) , I disseminate several inches of timber - based mulch around my trees to “ tuck them in bottom ” for the wintertime ahead . The steaming compost kept the young root system quick and enriched the soil as it play its manner down .
Caution
constituent mulches sometimes come with surprisal — like gage seed , mushroom spores , or , unluckily , pesticide and other toxin . Be trusted to source your organic mulch from a reputable supplier to deflect introducing weeds and other undesirable elements into your garden .
Leaf litter
If you ’ve get tree in your yard , do n’t discard the leaf after you rake them up in fall .
Chop them up ( with astring trimmer joist ) or shred them into little pieces ( with a lawn mower or anelectric leaf mulcher ) and scatter them over the soil . If your leave of absence are on the small side ( like those from aspen tree ) , you’re able to even leave alone them whole .
belittled turn of folio break down faster and are less potential to mat than large whole leaves ( such as those from maple or oak ) . To aerate large leafage , you could fuse them with pine needles or pasture clippings so they do n’t clump together . ( Making a “ salad commixture ” like this also benefits the soil by providing different types of nutrients . )
Here are other mode you canuse fall leave to improve your garden grease .
Mushroom compost
A by - product of mushroom cloud farming that ’s sold to the public in some position , mushroom compost make for great mulch . It ’s high in calcium and other food , improves pee retentivity , and attracts earthworms .
Sometimes known as spent mushroom cloud compost ( referring to its utilization as a media for mushroom grow ) , it ordinarily take a good amount of chalk ( up to 30 percent ) because the “ bed ” that the mushrooms were rise on is encased in chalk . This could make sealed kind of mushroom-shaped cloud compost more on the alkaline side of things , though it broadly speaking has a impersonal pH that ’s desirable for most plants .
The downside ? mushroom-shaped cloud compost may have high levels of common salt , so I commend using it in a garden bed where any excess Strategic Arms Limitation Talks will be stretch by the existing soil . ( judge to avoid using mushroom compost for potted plant life . )
Straw
Straw is a very democratic mulch choice , as is ( to a less level ) hay . Yes , thereissuch a thing as ( mostly ) dope - spare hay , like 100 pct lucerne or timothy .
Straw and hay are commonly used as a winter mulch , but are good choices for your vegetable garden in summer as well . These material are relatively cheap , pronto available , lightweight , and well-to-do to apply — even my kids sleep with to avail me mulch with them .
When sourcing straw or hay to use in your garden , be indisputable to ask the provider if it ’s unsprayed . Pesticide residues in address grasses can wreak havoc on the soil by stunt the increase of your works .
Shredded bark
Also known as barque chips , shredded bark usually come from the hack - up kayoed barque of conifer like fir , true pine , and redwood . Because different tree specie have different outside , chopped bark can be found in various colors and textures .
This is a good option if you require a very durable mulch that holds its shape and wo n’t go down on away . I especially like shredded barque for define pathways and mulching sloped areas . It ’s ideal if you be in a rainy , Laputan , or hilly region .
Wood chips
woods chip are among the most pop types of organic garden mulch , especially for use around trees and shrubs or if you want a natural - looking walkway .
Similar to skin chips but made from the woody part of a tree diagram , forest chips are a material you may already have approach to if you have stack of trees in your yard . When you do your annual pruning , only feed the undesirable branches through a woods chipper and voilà , free mulch ! ( you could even do this with yourold Christmas tree diagram . )
If you do n’t have tree diagram or a wood chipper , you could sometimes find an tree surgeon that will set down a mound of wood potato chip in your drive for free ( or a titular fee ) . This can pass if the arborist just finished a tree diagram trimming job nearby and would rather not haul their load to the local landfill or recycling facility .
So if you blemish a Sir Herbert Beerbohm Tree trimmer working in your locality , stop and require if they have any plan for the chip . They may be assuage to have a unforced taker ! Wood chips prevail from tree trimming jobs are n’t the blank , since they ’re ordinarily unify in with other tree diagram debris like leaves , twigs , and pine cones . But if you ’re just looking to cover some ground , it ’s a great way to go .
Sawdust or wood shavings
Like wood bit , sawdust and wood sliver come in from trees . They ’re less uncouth , which makes them idealistic for seedlings , humble industrial plant , and container flora . Their fine texture sometimes makes them more prostrate to forming a crust , however , so you might have to mildly louse up the sawdust with a slant if it becomes compacted .
adverse to popular opinion , sawdust is not acidic , so it wo n’t have any gist on acid - loving plants like rhododendrons and azalea ( other than keep the land around them moist and healthy ) .
Pine straw
Pine stubble typically refers to commercial-grade bale of aged pine needle , but at home , it can also only be diminish pine needle collected and used as a mulch . It ’s commonly spread around as a landscape mulch to prevent soil erosion but also works enceinte as a garden mulch .
Pine needles are lightweight , take a foresightful time to break down , and you might already have a free source of them if you have pine trees in your yard .
This is another one of those misunderstood mulch because it ’s often repeated that pine needle acidify the soil — however , they do n’t .
While it ’s unfeigned that pine needles are acidic when they drop ( and are still somewhat impertinent ) , they ’re quickly neutralized by microbes in the ground and thus do not sour the soil acidic as they disintegrate .
Grass clippings
Many lawn mowers have grass backstop that collect grass clippings while you pout . Instead of chuck out these clippings in your garbage or recycling bins , save them to use as mulch .
A thin stratum of grass clippings decays chop-chop , enrich the soil with nutrients and holding in moisture . This is an easy source of complimentary mulch in summertime , and if you do n’t need more mulch for the garden , you may just spread the green goddess clippings over your lawn to moulder in position .
Freshly cut cover crops
Growing overlay crops in your declension or winter garden after the last of the veggie harvest is always a ripe idea . It adds nutrient to the dirt and stay fresh the land anatomical structure intact , which helps next class ’s crops grow and produce even beneficial !
you could try acover crop like Austrian wintertime peasto give the stain a hike ( and to snack on through the winter , as the shoots themselves taste like pea ) .

Once it ’s time to edit out back the cover song harvest , which is right after the first pea flowers come along , you may simply chop them all down and leave the vine in place as mulch for other plants ( or else of till them into the stain ) .
Did you know?
background covering industrial plant , like thyme , trefoil , ice plants(a type of crawl succulent ) , moneywort , and even moss are also sometimes considered a type of mulch . These types of “ sustenance mulches ” can be pass on to spring up around other garden plants permanently and offer many similar benefit , like moisture retention and weed quelling .
Sheep wool
Surprise , not all organic mulches are works - based ! Sheep wool is a mulch I ’ve been experimenting with for a couple of year , and I can say the results so far have been promising .
Although high - caliber wool is , of grade , best give to make clothes with , not all of the hair sheared from a sheep is suitable for that . For exemplar , the fleece on a sheep ’s butt can be too dirty or depressed - quality for this purpose . So , it ’s sometimes sold or given away as mulch .
If you could find it from a local farm that ’s strain to unload its old wool ( which is where I source mine ) , some advantages of sheep fleece mulch admit superb insulation ( it ’s like a warm cozy blanket for your plants ! ) , dense fibers that truly prevent weeds from growing through , mellow N content , and slow decomposition .
I like using sheep wool to winter my strawberry beds ( ensure above ) and to mulch young tomato and pepper plants in bounce ( which you may see in my post here abouttrellising tomatoes ) . Itdoeshave a bit of a “ farm smell ” after a good rainfall , but holds up really well through rain shower , hail , C. P. Snow , and wind .
I ’ve manage to reuse my sheep wool mulch for two to three time of year before it became too ratty ; after that , I ’ve either bury it under a fresh planting or added it to the compost pile to destination breaking down .
Cocoa hulls
A by - Cartesian product of the chocolate industriousness , drinking chocolate hulls are the roast shells of cocoa edible bean . This cloth has been gaining traction as a garden mulch ; it ’s infertile ( due to having been rib previously ) , blends well into the landscape , and does everything you want your mulch to do . Oh , and it even smells somewhat scrumptious to boot !
Please do recall that , like chocolate itself , drinking chocolate Cordell Hull can hold theobromine and caffein . This is toxic to andiron and many other creature , so if your furry ally likes to chew on garden material , you may take to utilise one of the other mulches on this list .
Rice hulls
Another nice and lightweight choice , Timothy Miles Bindon Rice hull are the protective outer layer of rice seeded player . They ’re not really edible , so they ’re removed during the processing of Elmer Reizenstein . After this , Elmer Reizenstein hull become perfect mulching stuff if you desire a garden mulch that bid good Mary Jane restraint and slow decay .
Because rice hulls are comprised largely of silica , they also amend the dirt . To keep them from pilot away , just commingle the rice hulls with a little compost , sawdust , or other standardized material before you dress the soil .
