Too many gardeners sharpen only on crushed rock ’s function , not on its physique . They ’re preoccupied , clearly , with bloom multiplication , Pisces fertilizer , and how to keep bulb catalogues and credit cards in separate part of the planetary house . If they apply gravel at all , it ’s dutifully , as a pathway along cautiously planted bed , where it dish as a backdrop for the limelight - seeking blooms spilling over its edges . Or on a terrace as a optic pause between , say , the attention - call for corkscrews of Harry Lauder ’s Walking Stick ( Corylus avellana‘Contorta ’ ) and platter - size , come - hither dahlias . Gravel , for too long , has been cast in supporting roles as an worker whose business is just not to slip the show .
Lately , though , crushed rock has been gaining lover who prize its potpourri and versatility and treat it like a sensation . “ I ’m crazy for crushed rock , ” say Los Angeles landscape interior designer Marissa Mandel . “ I lie with to see things floating in it , whether that ’s advance beds or bigger stones . ” Mandel favors a locally quarry crushed rock promise Del Rio , which she uses in design schemes that range from arid to lush Moroccan . “ I love the phone of it underfoot and the strait of water on it when it rains , ” she gushes . “ I ’ll use it as grout on a patio , or as landing place - like steps edged with sword . ”
Gravel ’s growing popularity is relate to its increase availableness and also to an expand sentience of its inherent richness in color , configuration , and size of it . The only substantial limits in choosing gravel are your wallet ( the farther gravel is trucked , the more it cost ) , your willingness to give up plantable turf ( terra firma versus terra even more firma ) , and your level of interest in living sustainably ( think globally , pave locally ) . “ If a guest say to us , ‘ We want lava careen , ’ ” says Philadelphia landscape architect Tavis Dockwiller , “ we say , ‘ Move to Hawaii . ’ ”
Clients of Dockwiller ’s Viridian Landscape Studio are asking for local stuff , and not just so as to reduce the carbon footmark . “ For a farseeing sentence , you could go to any part of the nation and the landscapes would look the same , ” say Dockwiller . “ Now people are saying , ‘ It does n’t look like home anymore . ’ ” Dockwiller herself wo n’t use river - tumbled stones , even local ones , on a dry slope because nature would not have put them there .
Paving topically does n’t have to inflict a design constraint . “ We are consecrate with a geology that runs from aqueous to pyrogenic , ” says Minneapolis landscape architect Thomas Oslund . “ We employ anything from dolomitic limestone from the southern part of the state to crushed granite from the central part . We tailor our choice to the color and force we want . ” Oslund ’s go - to gravel are a snare John Rock , from Dresser , Wisconsin , and a crushed cherry-red limestone from Shakopee , Minnesota , so good at draining water that it lines baseball game diamonds throughout the Midwest and Canada .
Rock seems soggy , but over millennia it does change . Much of it was born as molten magma deep within the Earth , and all of it deduce its paint and form through contact with elemental forces : blast , wind , sun , and weewee . By the time it becomes gravel , it ’s been beat into pebble along rivers and ocean , or excavated from pit and crush .
Crushed crushed rock can be rough on stark feet , but the piece ignition interlock as they settle , providing a more stable airfoil and less scattering over time . Rounded gravel - despite silhouette that project cryptic tranquillity - is more like “ walk on ball charge , ” Oslund says . Both types allow water to percolate down into an aquifer , and in light colors can serve as a heat - reflecting mulch . Warmer - toned than pavement , cool and more indifferent than pasturage , crushed rock is weatherproof and malleable : it can follow curve as easily as it does unbent lines . Properly install , it acts as a weed roadblock , and the colours pick up on the adjacent plant palette .
Gravel is easy to set down , need fiddling maintenance , and , if well - contained , calls for only minimum replenishment every few years . It ’s cost - effective , given that it requires no mowing , watering , or fertilizing . Gravels researched for this report range in Mary Leontyne Price from $ 20 to $ 152 per cubic G ; a 20 - by-20 - foot terrace can be covered with roughly three three-dimensional yards .
hold in that it ’s biodegradable ( give or take an ice age ) , and gravel seems to be the open without a downside . Alas , it has a few . If silt builds up , the gravel clog . It wo n’t get around down , like mulch , into territory - better nutrients . Gravel can also break your heart . “ We originally had Shirakawa in our Sand and Stone Garden , ” tell conservator Sadafumi Uchiyama of Portland , Oregon ’s Nipponese Garden . With a texture that alternates between jagged and smooth , Shirakawa , a smutty - speckled granite from Kyoto , Japan , is prized for its power to sustain raked grooves ; those contemplation - move patterns hold up weeks unless conditions or rambunctious children intervened . Now the source is a protect waterway and it ’s illegal to harvest Shirakawa .
“ Right now we ’re using granite chips from Canada , ” Uchiyama says , “ but we keep looking for something better . ”
