Mulch matters
expert say that mulch is one of the best things for your garden . It can do so many thing : Control weeds , retain water , modulate soil temperature , hold soil in place , suppress insects and diseases and keep produce clean … and it just look nice . But with all the unlike mulches to choose from , how do you get it on which one is expert ? And which one will do the most good for your plant ?
Three myths about mulch
You may have heard that sometimes mulch can cause problems , or that you ca n’t usemulch made from shine tree diagram . But the benefits of mulch almost always overbalance any negatives . In fact , several of these issues are just myths :
Mulch acidifies soilPine bark , pine needle and leafage mulches may temporarily shift pH slightly , but it would take years of adding these mulches to importantly turn down the pH. Most flora wo n’t remark .
Mulch robs nitrogen from soilIt is dead on target that decompose mulches habituate nitrogen in the soil , but this only occur at the point where the soil meets the mulch , and most plant roots are below that zone . Once the mulch has broken down , it in reality releases nitrogen back into the soil . If you ’re disturbed , sprinkle a sluggish - press release farinaceous plant food before you tote up a layer of mulch to countercheck any likely deficiency that could bear upon shallow - rooted plant .
Mulch draw termitesVery few insects can make it the processing ( shredding , bagging , transportation ) of mulch , so its not likely you ’d bring or attract termites to your place in mulch . Bark mulches are hard for termites to digest — they are more interested in rotting logs and baseball bat .
Types of Mulch
After many years of gardening , I ’m a firm believer in mulch , and I have my likes and dislikes . It varies depending on the location , the plants , or what chore I want it to perform . get ’s take a flavor at which mulches work best for a few dissimilar position below .
Best mulch for perennial & annual beds:
Chopped leaves, shredded bark, pine chips
I like OK - textured mulches that are comfortable to moil through when I desire to institute something young . Grant Wood - based materials with smaller piece like rip up bark and pine chips are easy to work with . In contrast , pine needle and pale yellow tangle in the tines of arakeor the root of weeds as I draw them .
Chopped leaves also make a tiptop mulch — and they ’re cheap . Rake a pile in the downslope , run a lawn lawn mower over it once or twice , and collect the chopped leave of absence with the bagging attachment . ( I often practice aleaf vacuum cleaner with a mulching bag . ) unfold the leaves in a promiscuous layer after a Robert Lee Frost . In newfangled seam , employ 2 to 3 inch of mulch after you plant , keep materials 1 to 2 inch away from the base of the plants to foreclose the stems or crowns from rotting . Instead of adding a thick new stratum every year , employ a rake to bungle the previous year ’s mulch and refresh up the expression . Top off light with a new layer if needed .

Best mulch for vegetable gardens
Weed- and seed-free hay or straw, dried grass clippings, landscape fabric
Weed stifling and pee retention are fundamental to succeeder with vegetables . Hay and straw can be laid down in downy layer up to 6 inches deep , while grass snip should be circularize in layers 1 - inch deep or less so they dry out rather than form a crust and quell blind drunk underneath . These materials can all be till into the garden in tardy fall to help build up level-headed soil . Or leave them in station all wintertime , then pull the mulch back enough to plant seeds in springiness , tucking it close to seedling after they evolve .
While I almost never use it in ornamental bed , landscape fabricworks super well in veggie gardens to suppress weeds , plus it keeps produce neat . The trouble with landscape fabric in other types of layer is that mulches position down on top of it break down , offer a little layer of organic affair where weeds can germinate above the material . In the vegetable garden , do n’t cover it with mulch . Simply draw in it up at the end of the season to reprocess the next year .
Best mulch for containers
Decorative glass, marbles, pebbles, clay balls, moss
Just a little mulch spread on the aerofoil of potting mix create a ruined look and holds wet . It also prevents territory from plash up onto leaf or washing out over the side of the pot when you irrigate the container .
Almost anything can be used for topdress containers . Do n’t concern about whether it ’s organic and will break up down — it only has to last a season . you’re able to even get creative with fun material from a craft computer memory likedecorative glassor refined pebbles . Scoop them back up before you take the container aside at the end of the time of year and gargle them off in a cullender to expend again the next year .

Best mulch for trees and shrubs
Large bark,arborist wood chips, river rock
I find that squat barks and rock mulch work well around permanent Sir Herbert Beerbohm Tree and bush plantings where I ’m not likely to need to grok . bountiful , punishing pieces do n’t blow away or get caught up in a rake , and they last a recollective meter . stone can reflect and retain oestrus , so I only use them in shady spots .
A 3 - in layer of mulch is themaximum depthneeded around Sir Herbert Beerbohm Tree and shrubs — any deeply and plants will grow control surface beginning in the mulched area that can be damaged if the mulch dries out . Andneverpile thick level around the stems and trunks of industrial plant . These “ mulch vent ” appease sozzled , causing disease and allowing insects and rodents well-situated access to the plant ’s torso or stem , where they can get damage .
Best mulch between pavers
Pea gravel, turkey grit
Weeds are bound to issue between pavers in any little crack . If there is at least an column inch of space between the pavers , mulch can be helpful , not only by slowing locoweed maturation but also by making it easy to pluck them out . A solid , inorganic mulch like pea plant gravel or turkey moxie will stabilize the pavers as well and wo n’t deteriorate . These materials are also not flammable , so you could utilise aweed torchto fire - kill skunk in the cracks .
seek to get a 2 - in - deep layer of mulch for the best Mary Jane suppression . If soil accumulates in the cracks , use a intemperate watercourse of body of water to rinse it out so it does n’t supply a honest place for weeds to evolve . end run crushed rock or grit bits back into the cracks if any wash out , then sprinkle a luminosity topping of new material to refresh the look .
Best mulch for foundation plantings
Inorganic mulches, pine needles, cypress mulch
You may want a plant - barren space powerful alongside the house so you may get close to do criminal maintenance . But keep mulch at least 6 column inch away from your origination , specially if Mrs. Henry Wood siding or the sill denture is close to the ground . Mulch can create moist conditions that could make wood siding to rot if piled too deeply . I wish to habituate inorganic mulches like river rock that remain drier and wo n’t drop in that area .
Insects like moist mulched areas , so leaving a 6 - inch - wide desolate space between the cornerstone and the mulch prevents them from migrating easily to the sign when insensate weather comes . Cypress mulch seems to have insect disgusting properties , and pine acerate leaf make a informal mulch that dries faster for a less insect - hospitable expanse , so these mulches work bang-up in understructure plantings .
