If you are planning to use road salt as a de - icer on your sidewalk , driveway , or street this wintertime , you may be unpleasantly surprised in the springiness . route salt , or Na chloride , can be very detrimental to plant , tree , land , andgroundwater . table salt toxicity can harm , stunt , and even kill garden industrial plant that have been exposed to table salt spray or absorbed salt in the dirt . There are some alternative to avoid route Strategic Arms Limitation Talks environmental price that are beneficial to your garden and keep you dependable while the snow fall .
Living in a temperate rainforest , I ’m used to everything being green , not white . Over the last month my garden in Vancouver , BC , has been enshroud by a cover of snow and ice . While I get laid that many of the industrial plant will add up back in the springtime , I ’m also prepare for the losses . What I was not prepared for was the environmental wallop of route salt on my home garden .
Our city is largely poorly - equipped for extended periods of cold temperatures . You may call up get a line that snow needed to be trucked in for the 2010 Winter Olympics . It bamboozle here at times in the wintertime , but rarely hold out past the pointedness of novelty . When the snow start fall before Christmas in Vancouver , kids of all age donned their snowsuits and headed out to make snowpeople and slide down the hilly side street .
After four workweek of a admixture of precipitation and temperatures hovering around freeze , the downy white clobber has turned into grave ice . Do n’t get me wrong ; people are still enjoying the uncharacteristic conditions by skate on wintry ponds and residential streets . But while the street and sidewalk may be fun to skate on , they are not safe to take the air or motor on .
The city of Vancouver ’s strategy for pick up with the frozen residential streets is to offer buckets of road salt to melt the ice rink on the sidewalks in front of their planetary house . As a gardener , I ca n’t facilitate but be worried about the foresightful - term effects on our gardens , street trees , and lawn .
Road saltiness can be extremely damaging to vegetation . saltiness is pronto resolve into water and at high levels of tightness can become toxic plant . plant remove supernumerary Strategic Arms Limitation Talks by sending it out to leaves and branches which then die and fall off .
Salt can damage garden plants in two different ways . First , salt spray can get injury to the section of the plant life that are above dry land in the wintertime . Both evergreen plant and deciduous plants and trees will show browning on the leafage as well as bud dieback . The next year , the plant may not leaf out , flush , or fruit due to table salt damage to the overwintering buds . secondly , the salt plunge into the soil and can cause more damage in the spring . Plants that have been affect by high levels of salt in the ground could release jaundiced , have stunted ontogeny , increased disease and pest problem , send out mug , or just buy the farm .
There are plant life suitable for in high spirits levels of salt that can be planted near roads that are commonly treated with salt or near the sea . Plants in these gardens will invite a higher layer of saltiness nebulizer than your typical residential garden .
However , many Vancouver and area gardens are usually safe from this kind of far-flung salt toxicity . The metropolis ’s strategy to give out bucket of salt at the fervidness vestibule without accompany entropy on how to protect plants and garden is worrisome . I wait to see a number of hoi polloi confused about the state of their garden , lawn , and street trees near the sidewalks come next spring .
Shovel it!
We have worked heavily to keep our walkways light through the tried - and - on-key snow removal method acting of “ shoveling ” . I know that not everyone is able-bodied to shovel their sidewalks . It ’s not easy work . The free weight of the nose candy won the battle with our snow shovel and we are now using garden shovelful to acquit the sidewalks . I was glad to see many neighbors out shovel because using route salt as a First State - icer is a far more damaging method acting than a trivial cubital joint grime .
Sand and Fine Gravel
grit or fine gravel is a fine alternative to rock music salt . They add drain into the soil and wo n’t harm plants . Neither of these gritty alternatives will mellow the ice , but they will make it dependable to take the air and drive on . Keep in intellect that any crushed rock you add to your pavement will wash into the dirt . Choose sand or fine gravel if you do n’t want to spend hours sift out the rock ‘n’ roll in the springiness .
mention : I have also seen clause suggest kitty bedding but I ca n’t recommend it for garden safety as it is unclear how the ingredients in pot litter might impress the garden .
Wood Ash
If you have a fireplace , you may use Sir Henry Joseph Wood ash tree to help produce grip on streets and sidewalks . Wood ash is often total to compost and soil as it is a source of atomic number 19 and other element . Wood ash is alkaline , so it ’ll also help to ameliorate the acidic grease , and it ’s good to use near lawns . It ’s just not to apply wood ash tree with dot - fuck works like rhododendrons and blueberry .
Used Coffee Grounds
It should be no trouble to get coffee grounds in a city with a coffee shop on every corner ! Used coffee grounds can be used to create adhesive friction and are safe for most garden plants because they are pH neutral . coffee berry solid ground are also often add to compost and soils because they make an fantabulous soil amendment .
Yes , some of these option will certainly make your sidewalk — and your charge — muddy , but I ’ll mirthfully take the gunk over dead plants and sick grease . This snow and ice will be gone soon enough , and I , for one , will be ready for gardening time of year .
