In winter , low temperatures as well as too intense igniter , want of water ( when the soil has frozen the moisture in it can not be absorb by the roots ) , and idle words may cause damage . Some harm is right away due to the event of below - freeze temperatures on the tissues of tender plants ; other damage is collateral , for instance , the tearing and drying of ancestor that follow the heaving of the soil as a result of alternate freeze and melt .
It is well know that plants in poorly drain grime are more susceptible to winterkilling than specimens of the same kind grow in well drained place . Plants place in hollows or “ hoarfrost pockets ” are much more potential to be damage than those engraft where there is free air drain . The pick of favorable planting site is important as protection against damage by the cold .
Importance of Fall Watering
Trees and shrubs , particularly evergreen kinds , are less probable to get winter price if the soil in which they spring up is kept dampish throughout the fall . If this is done , their tissues go into the winter well add with wet and they are well capable to defy the desiccate effects of sun and wind when the priming coat is so frigid that it is difficult or impossible for them to absorb adequate supply of needed wet .
If fall rain are inadequate , evergreen shrubs should be soaked thoroughly each fall before the soil freeze . A mulch of leave-taking or uncouth compost applied immediately after the last lacrimation is good in insensate climates .
Antitranspirants
Where serious winters prevail , much scathe may be done to tree and shrubs , particularly to evergreen kinds , by dehydration make by their above - background role being display to the dry effects of sun and confidential information at times when their root word are in frozen dirt or in the ground so cold that absorption of moisture is forbid or slow up .
An effective way of reducing the damage of this character is to spray the foliation at the beginning of severe winter weather and once or doubly more at about monthly time interval with an antitranspirant ( antidessicant ) liquidity . Such sprays based on rubber latex or plastics are sold by dealer in garden supplies under various trade name name .
Antitranspirants are of peculiar economic value when used on evergreens growing in disclose location and for use on specimen that have recently been transplanted .
Mulching for Winter Protection
Very fine protective covering against moth-eaten is provided if an insulating layer of more or less liberal cloth is spread over the surface of ground occupied by the source of many plants . Such a layer either may prevent the underground fortune of the plants from freezing or may only prevent the ground from freeze as deeply as it otherwise would . In the latter pillow slip , at least some of the roots are probable to be in unfrozen soil and , if the plant is evergreen , it may still absorb at least some moisture to compensate for that passing from the aboveground foliage .
Winter mulching is really resorting to Nature ’s way of protecting plant life . When leaf diminish , they are blown among shrubs and other perennial industrial plant . Before they decay and deliver plant food for thought to the soil , they serve as a protection for roots and other below - ground part by keep a more even temperature in the soil over which they lie . Many gardener , instead of accept a moral from Nature , are inclined to neatness and artificiality and so rake up these leave in crepuscule . This is not always good exercise . If it is done , in many orbit it is desirable to replace them with wintertime mulch .
diminished bush , specially those that have been of late planted or are not dependably hardy , can be protect by put a layer of wry leaf , several inches loggerheaded , around them . The leaves should not be packed down so that aura is leave out but should be left loose . Chicken wire may be used to contain them and prevent them from being blown away .
turgid shrubs and evergreens do good greatly from experience the soil covered with a 3 - 6 in . layer of half - rotted compost , loose , strawy manure , half - rotted leaves , or any other appropriate mulch cloth that stay fairly loose and does not pack down and take out air .
Winter Covering
In part , this term is interchangeable with winter mulching , but not wholly so . Winter covering include the various types of protection that cover the top , the above - land portions , of plant . Winter natural covering is normally removed with the coming of springiness ; winter mulch are often leave in position to decay gradually and form nourishment for the plants , or are forked into the earth to disintegrate beneath the surface .
Among industrial plant that are wintertime covered in cold part are trees , bush , and evergreens likely to be injured by cold , perennials and bulb likely to be damage by scurvy temperature and deep freeze of the soil , and immature or new transplant specimens that may be harm by the heaving of the soil due to switch freeze and thawing .
Young plant life of many perennials and biennials are not thoroughly winter - hardy in all region . Where they are reasonably tender , or where there is a risk of the small plant being heave out of the ground by alternate freezing and warming , they are benefitted from a low-cal wintertime cover . flora such as Foxgloves and Canterbury Bells that retain their foliation during wintertime will not last , however , if a heavy stratum of winter covering stuff is spread over them . It should be just chummy enough to shade off the soil , so check too frequent alternate freezing and thawing . branch from Pines , used
Christmas trees or other evergreen plant are very satisfactory as a wintertime program , as also is salt marsh hay .
Delphiniums are sometimes protect by having sand or coal ashes heap around and over their pate . This is specially deserving while in gardens that suffer from excessive moisture .
Irises and Peonies may not need winter shelter if they were plant early . However , young plants set out rather deep in the season may suffer injury from heaving by frost unless it is prevented by a weak covering . This is peculiarly desirable if the soil is corpse .
Bulbs
Some hardy bulbs such as Daffodils ( Narcissi ) may suffer legal injury from life-threatening hoarfrost if they are planted late in bed or borders . They should therefore be plant as early as procurable or be covered with 4 - 5 in . of straw , salt - marsh hay , bark , leave , branches of evergreens or like material . dauntless bulbs institute in dope sod do not call for this tribute .
Bulbs that are on the borderline of hardiness in any given region , and even many that are usually regarded as cutter , may survive the winter outdoors if they are covered . For nearly unfearing variety , those that are just slightly affectionate — as , for instance , Brodiaea uniflora , the Spring Starflower , in southerly New York — a embrace 4 - 5 in . thick of any of the materials recommended above for sturdy bulbs will prove sufficient . For more tender kind — such as Gladioli and Montbretias , in southern New York — a layer about a foot thick will usually enable them to survive by preventing the frost from striking deeply enough to harm them . Even Dahlias may be kept live through the winter by this method in regions where they would otherwise surely die .
When wintertime cover is used , it is important not to put it into position too too soon , not until the earth has frozen to a depth of an in or two , and it should be off gradually , not all at one time in springtime . If put on too early , many winter - covering materials attract mice and other rodents that may take up wintertime quarters under their protection ; these are likely to damage the plants . Too early or too speedy remotion in spring may result in severe damage to tender shoots by sun , wind and late rime .
Shelters and Wrappings
In addition to stuff laid directly upon the ground or the plants , there are types of wintertime cover that involve building a tax shelter of burlap or standardised material about the plant life and wrapping the aboveground parts in hay , stubble , paper and other protective materials .
Evergreens , even kinds consider fairly hardy , are much more susceptible to winter trauma than are leaf - losing ( deciduous ) trees and shrubs . They transpire moisture through the leaves in winter as well as in summer , and protective covering from in high spirits winds and hopeful sunshine may be very necessary in cold part , specially for those evergreen plant that are not aboriginal . Burlap , neatly boom to 2 by 4 - in . reenforcement on the exposed side of the plants , is helpful . A few branches of Pines or other evergreen stuck in the soil so that they give protective shade may be all that is involve for some of the modest , growing evergreen plant nonimmune to wintertime harm .
Deciduous trees and shrub , the tops of which are more or less warm , as are , for example , Al-Jama’a al-Islamiyyah al-Muqatilah bi-Libya Tree in the vicinity of New York City , and Hydrangea macrophylla rather farther north , may be successfully brought through the wintertime by draw their upper parts together , wrap them in a thick layer of shuck , hay , newspaper , former cover or other cloth that provide estimable insulation , and incase the whole in a layer of waterproofed build paper . This is done before very operose frost , and the covering is removed in give after danger of terrible Robert Frost has transcend .
Roses
In area of stale winters , rose require aegis . Hybrid Tea and Floribunda bush Roses will defy a temperature of about 12 degrees F. but are likely to be damaged by alternating mild and stale spells . They can be protected by mound stain , buckwheat Hull , or peat moss around the base of the plants , covering them to a pinnacle of at least 8 in . Where the temperature drops below zero F. , they should have stain mound up to them and , after the earth is freeze to a depth of an in or two , a stocky coating of strawy manure or leave-taking should be place over this .
Tree or standard Roses will bear about 15 degree F. Where temperatures drop below this , they should be laid along the ground and covered with soil and a stratum of leaves , straw or other winter masking . In the most northerly regions , they must be lifted and buried in a deep in the flat coat .
Large - flowered and everblooming climber will survive at 5 degrees F. but are comfortably mounded as recommended for Hybrid Teas where the temperature extend low-pitched . In colder regions , it is safest to lay the shoot down on top of the ground and shroud them with soil .
Climbing Hybrid Teas and Floribundas should be mounded with soil in a similar fashion and , in cold regions , repose down along the dry land and cover with soil and mulch .
Wintering Plants Indoors
It is common practice to protect many tender plants by growing them over wintertime in nursery , windowpane gardens and in cold skeleton . In the former locations , the plant normally continue to develop through the winter and need attention in the matters of tearing , fertilizing and other cultural care so as to flourish .
Plants wintered in cold frames grow little or not at all until tender spring weather condition arrives .
