Preventing and Repairing Winter Damage

Learn how to identify, prevent, and fix it—no matter where you live

Over my many years of dealing with wintertime harm , I have receive just about every kind under the Dominicus — or coke , I should say . From an evergreen plant shrub ’s burn leaves to the entire death of flower and leaf buds , winter can be a withering season for our gardens .

Across the United States , the types of damage variegate , due to difference in climate and flora specie , but winter - weather hurt is difficult to avoid . Some damage , such as a tardy frost turn early flowers on magnolias to glop , is chronic ; with a small expectancy , you could do something about it . What is hard to predict — and almost impossible to avoid — is sudden , severe damage that forces plant to use stored food reserve to replace or repair damage parts . This impairment normally occurs just as bounce arrives , when the plant usually apply substitute to produce new growth . The impression of this damage , specially if it occurs over multiple turn season , can deoxidise a plant life ’s sustainability , making it weaker and more susceptible to disease .

With the vulgar types of wintertime damage , it ’s important to bonk why they materialise , how to make do with them , and , most crucial , what you could do to protect your plant from falling dupe in the futurity .

Broken branches

Broken branches should n’t be removed right away .

Ice , snow , hail , wind , and other winter - atmospheric condition extremes often cause branches to split up , altering the plant ’s appearance and , possibly , its productivity .

How do I situate it?Unless a chance exists , wait until the end of wintertime to prune all broken twigs and branches back to within one fourth part of an inch above a alive bud or to the leg collar of the nearest live branch . This pruning to reshape the industrial plant can also stimulate young growth in the coming season .

How do I keep it?Removing the most susceptible parts of a works prior to the onset of winter atmospheric condition can help with succeeding breakage . branch that seem partially deadened or especially weakly would qualify for early removal .

Frost damage

Frost damage can take place without warning .

Pruning or fertilizing in tardy summer or former pin may stimulate young increment , which is ineffectual to acclimatize ( inure off ) before sudden temperature drops or unexpected wind or deoxyephedrine storm show up . The newfangled foliation call on an wretched brown or opprobrious . When temperatures start to warm up up and plant break dormancy , an unexpected frost or freeze down can , again , shoot down new growth .

How do I repair it?Damaged leaves and flowers may drop by themselves after the risk of severe atmospheric condition has passed , or you could dress to remove poorly damaged or crushed subdivision to help stimulate Modern growth . Most plants will usually grow novel leaves if branch and buds have not been injured too severely .

How do I foreclose it?Avoid pruning or fertilizing in recent summertime or early decline . This will help prevent a sudden push of fresh , fond increment . If leaf signs suggest an covering of plant food is in order , use only a slow - release or organic option . If you must prune at this time , do it meagrely ; waitress , instead , until a plant arrive at full dormancy . In spring , wait until the plant has break dormancy and the threat of down in the mouth temperature has passed before tackling any pruning undertaking .

Desiccation

Desiccation gets bad with previous pruning .

This type of legal injury appears when a plant ’s tissue paper dry out out from wind or ice - thawing chemical substance , deficiency of moisture in the air or soil , or a “ wrong plant / incorrect location ” scenario . evergreen are peculiarly susceptible because their farewell never halt drop off water , even during their “ dormant ” season . When these leave disappear more water than the root take in , you ’ll see some damage leaf .

During severely inhuman atmospheric condition , the ground surrounding the origin organisation can block , which decreases or stops the consumption of water . If the conditions turns warm and sunny while the undercoat is still frozen , evaporation increases and color or “ burned ” foliage starts to appear . The discredited leafage are generally concentrated on the side of the plant face the wind , where drying up is greatest .

How do I situate it?Most leaf will fall or be pushed off by unexampled increment , but those that do n’t can be hand - stripped or pruned away . Premature pruning can increase damage by break vulnerable inner leaves , so resist come to the delivery of your plants too early .

How do I foreclose it?If conditions are ironic in fall , make certain you irrigate to compensate for the lack of rain . If plants commence to show signs of winter sunburn , pull out the hosepipe on the warm day possible ( to head off the hose freeze and bursting ) and irrigate the frozen ground to melt the moisture frozen in the soil and make it uncommitted for uptake . It ’s also a near idea to maintain a 2- to 3 - column inch - thick layer of mulch to reduce water system personnel casualty .

Do n’t get to applying antidesiccants , which put waxy coatings on evergreen leaf , because they degrade rapidly . Although unattractive , windbreaks of gunny , canvas , or similar material can be set up to protect small evergreens . Do this in autumn to help slenderize the wind ’s forcefulness and to avail shadow your plants .

Frost heave

freeze heave can damage roots .

Frost heave takes place when period of soil stop dead and thawing push small , shallow - root plants out of the ground . This prevent the plants from having unshakable contact with the stain and divulge the root to nose desiccation .

How do I situate it?If a plant is heaved from the ground , replant it as presently as the grease thaws . If the tooth root organisation is small enough , you might be able to push the plant back easily into the soft dirt with your fingertips .

How do I prevent it?Use mulch . It act as a buffer to the soil and reduces the amount of alternative freezing and thawing of the filth .

Rodent damage

Rodent damage is gentle to ward off .

Mice , vole , and rabbits jaw off tree barque at priming level or below . They sometimes completely remove the barque around the tree ’s base , do the works to buy the farm .

How do I fix it?Once the damage is done , there is not much you’re able to do . Allowing the tree diagram to seal wounds on its own and taking steps to prevent additional legal injury are the best ways to manage the situation .

winter damage

How do I prevent it?Keep mulch off from the base of operations of the tree , and try out it oft for the presence of mouse or voles . A safety is the most effective mode of bar . Place a strip of galvanized screen or mesh around the trunk , and secure it with a twist of wire to keep the strip from unroll . Be trusted to drive the end of the bun into the background to terminate critters from attacking below the soil surface . This metallic element guard will last indefinitely and can be go forth in spot all year .

Salt burn

table salt suntan has a bare answer .

Road overspill contains break up salts that not only wound industrial plant directly but also can change the anatomical structure of the stain , get it to become compacted . This status restricts the nutrients , water , and O available to the plants , putting them under stress . Shoot crest and young leaves unremarkably receive the most damage . One of the symptom of salt scathe is dried , burnt leafage edge .

How do I fix it?Where runoff is inescapable , flush the area around the industrial plant in other outflow by applying 2 inches of water over a two- to three - 60 minutes flow , take over three Day later . This will strip much of the salt from the grunge . If salinity spray from the route surface is a trouble , habituate weewee to rinse the foliage and branches of any affect industrial plant when salt spray is heavy and again in early spring .

How do I prevent it?Don’t pile snow check salt around industrial plant or trees or put it where runoff might pass on plant roots . involve route - maintenance workers if they can direct piquant runoff away from your property . When pick out specie for a fresh wayside planting , minimize the potential difference for salt terms by planting salt - tolerant selections . set up a low wall or hedge of salt - tolerant evergreens , which can block saltiness spray aside from sensitive plants nearby .

call back the scathe that common salt can cause when removing ice rink from sidewalks and driveways . Instead of tossing a handful of rock’n’roll salt on slick surface , stick with sand or sawdust to improve adhesive friction .

Some salt alternatives are better for the environment

throw just any chemical substance listed as a deicer onto your sidewalks can wind up contaminate local bodies of piss . Consider , instead , using new eco - friendly salt alternatives , like calcium chloride . Some products even apply vegetables , such as beets , as their primary factor . Many not only are dependable for the surroundings but also can actually keep your walk ice - free longer because they work better at low temperature , unlike their salt - based counterparts .

Sunscald: Does it really exist?

A type of winter damage call sunscald ( also known as frost wisecrack ) is still being researched . While barque opening and closing may be link up to wintertime damage , bark split seem to pertain more to prewinter wound or injury than to any one season ’s temperature extremes . Previously recommended luggage compartment - auspices methods , such as Sir Herbert Beerbohm Tree wraps and reflective paints , are broadly unneeded and ineffective .
