genus Pinus koraiensis is a medium to large , broadly conical , evergreen conifer . The needle are acquit in fives , up to 4 1/2 in long , dark green above , grayish below , the overall effect is an attractive racy green . It is a hardy pine with a rather open , loose growth habit . The bark is gray brown , exfoliate to expose cherry-red browned barque beneath . It is a adept specimen or grouping Sir Herbert Beerbohm Tree and is rarely troubled by pests . Native to Korea , introduced 1861 . pine tree are one of the most diverse radical of evergreen conifers , over 90 coinage are distributed throughout the Northern Hemisphere . Although most are orotund trees , they can take a low growing bush form . Pines have been very crucial commercially , in timber production , as well as a diversity of other manufactured products such as turpentine and resin . They tend to be more tolerant of varying soil types and urban environments than either Picea or Abies . Pines lean to evolve tap source , so one should not attempt to transpose them from the state of nature . All species are grown from seed , with highly varying seed stratification requirements . They can be subject to many diseases , such as damping off , root rot , dieback , blister rusting , pestilence , blight , musical scale , pine needle miner , pine weevil , barque beetles and pinewood nematode . Well situated plant should be relatively trouble free . They suffer salt damage along highways and can get gratuity burn in areas of gamy sulfur dioxide or ozone . In worldwide they do not involve fertilization , which can cause overgrowth .

Light
You will notice that sunshine and subtlety pattern change during the day . The western side of a house may even be shady due to shadows cast by large trees or a anatomical structure from an contiguous property . If you have just bribe a novel home or just beginning to garden in your older home , take time to map sun and shade throughout the Clarence Shepard Day Jr. . You will get a more accurate feel for your site ’s dependable calorie-free conditions . Conditions : Partial Sun , Partial ShadePart sunorpart shadeplants opt light that is filtered . Sunlight , though not direct , is important to them . Often morning sun , because it is not as strong as good afternoon sun , can be considered part sunshine or part shadowiness . If you live in an area that does not get much intense sun , such as the Pacific Northwest , a full sun exposure may be fine . In other areas such as Florida , plant in a location where good afternoon shade will be receive . Conditions : Full to Partial SunFull sunlightis needed for many plant life to accept their full potential . Many of these plants will do fine with a little less sun , although they may not bloom as heavily or their leafage as vibrant . area on the southern and westerly sides of building usually are the sunniest . The only exception is when houses or buildings are so close together , shadows are contrive from neighboring properties . Full sunshine usually means 6 or more hours of unmediated unobstructed sunlight on a sunny day . fond sun receives less than 6 hours of sun , but more than 3 hours . Plants able to take full sun in some climates may only be able to stand part sun in other climate . make out the finish of the flora before you purchase and plant it!Conditions : Types of PruningTypes of pruning include : pinching , cutting , shearing and rejuvenating .
Pinching is take out the prow tip of a young flora to advertize branching . Doing this avoids the need for more severe pruning by and by on .
cutting involve bump off whole branches back to the trunk . This may be done to afford up the interior of a plant to permit more light in and to increase strain circulation that can cut down on plant disease . The best room to begin cutting is to begin by removing dead or diseased wood .
Shearing is flush the aerofoil of a shrub using helping hand or electrical shear . This is done to maintain the desired anatomy of a hedging or topiary .
restore is remotion of old branches or the overall simplification of the size of it of a bush to restore its original flesh and size . It is urge that you do not remove more than one third of a plant at a prison term . Remember to polish off offshoot from the interior of the plant as well as the outside . When rejuvenating plants with cane , such as nandina , cut back canes at various height so that plant will have a more natural look . Conditions : Light and Plant SelectionFor good plant public presentation , it is worthy to play off the right flora with the available light conditions . Right plant , correct position ! Plants which do not receive sufficient illumination may become pale in color , have fewer leaves and a " leggy " stretched - out appearance . Also require plants to grow slow and have fewer blooms when light is less than desirable . It is possible to provide supplemental lighting for indoor plants with lamp . plant can also find too much Christ Within . If a shade loving plant is display to direct sun , it may wilt and/or cause leaves to be sunburn or otherwise damage .
Watering
Planting
Deciduous trees like maples ( those that loose their leaves in the fall ) can be dug up and sold with their stripped roots expose . Because most of the radical system is misplace in digging , sufficient top ontogenesis should be removed to indemnify for this exit . This may be done at the nursery before you buy the plant or you may have to prune at the time of planting . Select and head back the better scaffold branches , i.e. those branch which will form the principal lateral social structure of the future ripe tree diagram . Remove all other extraneous side branches . If the tree diagram seedling does not have branches , let it to grow to the desired height of ramify then lift it back to stimulate the lower buds to organise branches .
Ball and gunny tree diagram are dug up with their root systems more or less intact . This was mostly done for conifer and broadleaf evergreens , but has become common for deciduous trees as well . Since some root mint is lost in the digging stage , a brightness pruning is generally call for . head up back the plant to repair for this loss and to advertize branching .
Trees that are turn in containers generally do not loose roots in the transplant phase . Therefore you do not in the main have to prune them unless there is some ancestor injury or limb impairment in the planting process .
Once you have your trees plant , be patient . Do not remove shoot from the trunk early on as these allow the tree to grow more rapidly and also shade the raw young trunk from sun - scald . Wait a few old age to begin training the tree to its ultimate word form . How - to : Staking TreesStakingis done otherwise depend on the size and flexibility of the tree , and the windiness of the planting situation . Generally only tree that are planted in windy , exposed locations need to be staked . For most tree , a low interest is preferred , to let the tree move of course . For windy areas or flexible tree , use a high bet . For trees more than 12 feet tall , use two low stake on opposite sides of the Sir Herbert Beerbohm Tree or several guy ropes . The ties used involve to conciliate growth and not make bark impairment with friction . Buckle - and - spacer affiliation can be establish at garden centers , they are expandable and have a protective spacer . Ties without spacers should be formed into a figure eight to create cushioning . late work have show that when adventure a tree diagram , render enough leeway so that the tree can move back and away in the fart . Stronger ascendant will develop this path . If the tree can not move back and forth , these important roots will not grow and the tree diagram might hang over during a storm , once stakes are removed . When found a Sir Herbert Beerbohm Tree , stake at the metre of planting if punt is a requisite . How - to : Planting a TreeDig out an sphere for the Sir Herbert Beerbohm Tree that is about 3 or 4 times the diameter of the container or rootball and the same depth as the container or rootball . Use a pitchfork or shovel to scarify the sides of the hole .
If container - grown , put down the tree on its side and remove the container . Loosen the roots around the edges without breaking up the root ball too much . Position tree diagram in centre of trap so that the salutary side faces onwards . You are quick to begin occupy in with soil .
If planting a balled and burlaped tree , position it in hole so that the best side faces onward . Untie or remove nail from burlap at top of ball and pull gunny back , so it does not stick out of hole when soil is put back . celluloid burlap should be removed as it will not decompose like rude gunny . orotund trees often come in wire basket . Plant as you would a b&b plant , but cut as much of the wire off as possible without actually removing the basket . Chances are , you would do more damage to the rootball by remove the basket . Simply cut away wires to entrust several big opening for root .
fill up both holes with soil the same way . Never repair with less than half original soil . Recent studies show that if your ground is loose enough , you are better off adding little or no dirt amendment .
Create a water mob around the proscribed sharpness of the hole . Not only will this conseve water , but will take moisture to perimeter stem , encourage out increment . Once Sir Herbert Beerbohm Tree is prove , water doughnut may be level off . Studies show that mulched trees turn faster than those unmulched , so add a 3 " " bed of pinestraw , compost , or pulverized bark over backfilled area . murder any damaged limb .
Problems
Prevention and Control : No bar uncommitted . Control by handpicking or spraying with a advocate insecticide . Birds , mallet and computer virus usually keep the sawfly under ascendancy .
Pest : MealybugsSmall , wingless , tiresome - livid , easy - bodied insects that create a waxy powdery covering . They have pierce / take up backtalk parts that sop up the sap out of plant tissue paper . Mealybugsoften look like small piece of cotton and they tend to congregate where leaves and stems branch . They attack a wide range of industrial plant . The young tend to move around until they incur a desirable alimentation stain , then they flow out in colonies and provender . mealy bug can weaken a industrial plant leading to yellow leaf and foliage drop . They also produce a sweet message called honeydew ( coveted by emmet ) which can lead to an untempting ignominious open fungal growth yell pitchy mold .
Prevention and Control : Isolate overrun plants from those that are not . confabulate your local garden center professional or the Cooperative Extension role in your county for a legal insecticide / chemical recommendation . Encourage instinctive enemies such as noblewoman beetles in the garden to help reduce universe levels of mealy hemipteran . Fungi : RustsMostrustsare host specific and overwinter on leafage , stems and spend flower rubble . Rust often appears as diminished , bright orangish , sensationalistic , or brown pustules on the underside of leaves . If relate , it will leave a colored spot of spore on the finger . induce by fungi and spread by splashing water or rain , rust is high-risk when weather condition is moist .
Prevention and Control : Plant immune varieties and leave maximum air circulation . Clean up all debris , especially around plants that have had a job . Do not irrigate from overhead and pee only during the sidereal day so that plants will have enough sentence to dry before night . put on a antimycotic labeled for rust on your plant . Pest : Scale InsectsScales are dirt ball , have-to doe with to mealy hemipteron , that can be a problem on a wide variety of industrial plant - indoor and outdoor . Young scales Australian crawl until they find a good feeding site . The adult females then lose their legs and persist on a spot protected by its hard shell stratum . They appear as bumps , often on the lower English of leaf . They have pierce back talk percentage that suck in the sap out of industrial plant tissue paper . weighing machine can weaken a plant result to chicken foliage and leafage drop . They also produce a angelic substance cry honeydew ( covet by ants ) which can direct to an unattractive black-market open fungous growth call sooty cast .
Prevention and Control : Once install they are toilsome to control . Isolate overrun plant away from those that are not infested . confer your local garden heart and soul professional or Cooperative Extension place in your county for a legal passport regarding their control . Encourage raw enemies such as parasitic wasps in the garden . Diseases : BlightBlights are cause by fungi or bacteria that kill plant tissue . symptom often show up as the rapid spotting or wilt of foliation . There are many different blight , specific to various plant , each need a varied method of ascendancy .
Miscellaneous
You will often get word loam referred to as a sandy loam ( have more gumption , yet still plenty of organic matter ) or a clay loam ( dense on the clay , yet workable with good drainage . ) The addition of organic matter to either guts or clay will result in a loamy soil . Still not certain if your land is a sand , clay , or loam ? judge this unsubdivided test . Squeeze a handfull of somewhat moist , not soaked , grunge in your hand . If it form a tight ball and does not fall aside when softly exploit with a finger , your soil is more than probable clay . If stain does not form a ball or crumbles before it is knock , it is sand to very sandy loam . If stain forms a ball , then crumbles readily when lightly exploit , it ’s a loam . Several quick , wanton hydrant could mean a mud loam . Glossary : TolerantTolerant have-to doe with to a plant ’s ability to put up exposure to an international condition(s ) . It does not mean that the plant thrives or prefer this situation , but is able-bodied to adjust and continue its lifetime oscillation . Glossary : PruningNow is the preferred time to dress this industrial plant .
