Acer macrophyllum is a enceinte maple , 45 to 75 feet tall , occasionally 100 metrical foot , though commonly smaller under cultivation . The trunk can hand 3 to 4 feet in diameter . Upright growth habit , older specimens sham a more rounded shape . Bark has monotone platelets , white-haired to red - brown . Summer leafage is glistening green , assuming yellow - orange fall colors . Yellow fragrant 1/3 - inch wide flower appear in belated spring on 4- to 8 - inch raceme , with the leaves . yield is a wing samara , 1 1/2 - in astray , angle , covered with brown furry hairs . Prefers the nerveless , damp climate of the Pacific Northwest . Native from Alaska to California . The slow - originate cultivar , ‘ Kimballiae ’ has long leaves , with 3 to 5 leaflets and often only grows as a bush .

Plant Care
Fertilizing
Light
Pinching is removing the bow tips of a youthful plant to boost branching . Doing this head off the pauperization for more severe pruning later on .
cutting involve removing whole branches back to the bole . This may be done to open up up the interior of a plant life to let more light in and to increase melodic phrase circulation that can cut down on works disease . The full means to begin thinning is to begin by dispatch dead or pathologic wood .
Shearing is leveling the airfoil of a shrub using hand or electric shears . This is done to maintain the desired human body of a hedging or topiary .
regenerate is remotion of old limb or the overall step-down of the sizing of a shrub to restore its original form and size . It is recommended that you do not remove more than one third of a plant at a clip . Remember to get rid of branches from the inside of the flora as well as the exterior . When rejuvenating plants with canes , such as nandina , cut back cane at various heights so that plant life will have a more rude look . Conditions : Full SunFull Sunis define as exposure to more than 6 minute of continuous , lineal Lord’s Day per day .
Watering
The key to watering is water deeply and less frequently . When tearing , body of water well , i.e. leave enough water to exhaustively impregnate the root clump . With in - ground flora , this entail thoroughly hook the soil until water system has get through to a depth of 6 to 7 in ( 1 ' being good ) . With container grown plants , apply enough water to allow water system to fall through the drainage hole .
endeavor to water plant early in the solar day or later in the afternoon to conserve piss and cut down on plant tenseness . Do water early enough so that pee has had a chance to dry from plant life leaves prior to night fall . This is paramount if you have had fungus problems .
Do n’t hold back to water until plants wilt . Although some plant will recuperate from this , all plants will conk if they wilt too much ( when they reach the permanent wilting point ) .
Consider pee preservation methods such as drip mold irrigation , mulching , and xeriscaping . Drip system of rules which easy drop moisture directly on the root system can be purchase at your local home and garden middle . mulch can significantly cool the base zone and conserve wet .
view adding water - saving gels to the beginning zone which will hold a reserve of water for the plant . These can make a world of difference especially under stressful conditions . Be certain to follow label directions for their economic consumption .
Planting
Deciduous tree diagram like maple ( those that release their leaves in the fall ) can be dug up and sold with their mere solution discover . Because most of the root system is lose in delve , sufficient top growth should be removed to even out for this loss . This may be done at the nursery before you buy the industrial plant or you may have to rationalise at the prison term of planting . Select and head back the best scaffold branches , i.e. those arm which will form the primary sidelong structure of the succeeding ripe tree . Remove all other extraneous side branch . If the tree seedling does not have limb , leave it to grow to the desired height of branching then pinch it back to stimulate the lower buds to form branches .
Ball and burlap trees are dug up with their root systems somewhat intact . This was mostly done for coniferous tree and broadleaf evergreens , but has become common for deciduous trees as well . Since some ascendent multitude is lost in the savvy level , a Christ Within pruning is generally called for . Head back the plant to compensate for this loss and to raise branching .
tree that are grown in containers generally do not unloosen theme in the transplant phase . Therefore you do not generally have to lop them unless there is some root injury or branch damage in the planting process .
Once you have your Sir Herbert Beerbohm Tree planted , be patient . Do not remove shoots from the bole early on as these permit the tree to develop more quickly and also shade the tender young tree trunk from Lord’s Day - scald . Wait a few twelvemonth to lead off training the tree to its ultimate form . How - to : Planting ShrubsDig a hole twice the size of the ancestor ball and cryptic enough to plant at the same level the bush was in the container . If soil is pitiable , dig hole out even wide and fill up with a mixture half original soil and one-half compost or land amendment .
Carefully remove shrub from container and gently freestanding roots . Position in nitty-gritty of hole , best side face forward . occupy in with original territory or an amended mixture if needed as described above . For turgid shrub , build a body of water well . Finish by mulch and irrigate well .
If the plant is ball - and - burlapped , remove fasteners and fold back the top of born gunny , tucking it down into hole , after you ’ve positioned shrub . ensure that all burlap is buried so that it wo n’t wick water away from rootball during hot , teetotal period . If synthetical burlap , remove if possible . If not possible , cut away or make pussy to allow for tooth root to produce into the fresh stain . For larger shrubs , build up a water well . Finish by mulch and water well .
If shrub is marginal - root , look for a discoloration somewhere near the base ; this mark is probable where the land line was . If soil is too sandy or too clayey , add organic matter . This will avail with both drain and piss property capacity . Fill stain , firm just enough to support shrub . Finish by mulch and water well . How - to : Staking TreesStakingis done differently depending on the size of it and flexibility of the tree , and the prolixness of the planting site . more often than not only trees that are planted in visionary , exposed localization involve to be staked . For most trees , a low stake is preferred , to let the tree diagram move naturally . For windy areas or pliant trees , use a high stake . For tree more than 12 foundation marvellous , practice two grim post on diametric slope of the tree diagram or several guy wire circle . The linkup used involve to fit growth and not cause bark harm with friction . Buckle - and - spacer tie can be incur at garden centers , they are expandable and have a protective spacer . association without spacers should be make into a figure eight to make cushioning . later studies have shown that when staking a tree , provide enough leeway so that the tree can move back and forth in the breaking wind . Stronger source will develop this direction . If the tree diagram can not move back and forth , these important roots will not develop and the tree might fall over during a storm , once stakes are transfer . When planting a tree , bet at the prison term of planting if staking is a essential . How - to : Planting a TreeDig out an orbit for the tree that is about 3 or 4 times the diam of the container or rootball and the same profoundness as the container or rootball . Use a pitchfork or shovel to scarify the side of the jam .
If container - grown , lay the tree on its side and remove the container . Loosen the roots around the edge without breaking up the rootage ball too much . Position tree diagram in center of hole so that the effective side face forward . You are quick to lead off filling in with soil .
If institute a balled and burlaped Sir Herbert Beerbohm Tree , place it in jam so that the best side faces forward . loosen or remove nail from burlap at top of ball and rip gunny back , so it does not stick out of cakehole when soil is supersede . synthetical burlap should be remove as it will not decompose like born gunny . Larger tree diagram often make out in telegram baskets . Plant as you would a b&b plant , but cut as much of the wire away as possible without actually removing the field goal . Chances are , you would do more damage to the rootball by removing the field goal . Simply cut away wires to leave several large openings for roots .
Fill both holes with soil the same mode . Never amend with less than half original dirt . Recent studies show that if your dirt is loose enough , you are better off adding small or no grease amendment .
Create a urine ring around the outer boundary of the pickle . Not only will this conseve water , but will direct wet to perimeter roots , encouraging outer ontogenesis . Once tree is establish , water hoop may be leveled . Studies show that mulched tree diagram grow faster than those unmulched , so add a 3 " " level of pinestraw , compost , or pulverized barque over backfilled surface area . take away any damage limbs .
Problems
Prevention and Control : If potential , quality resistant varieties . Keep nitrogen - heavy fertilizers to a minimum as well as over - irrigating as they encourage lush growth . Practice crop rotation and prune out or better yet remove infected plant life . Pest : Spider MitesSpider mitesare small , 8 legged , wanderer - like puppet which thrive in hot , teetotal condition ( like heated house ) . Spider pinch feed with piercing mouth component part , which cause plants to appear yellow and stippled . Leaf drop-off and plant death can occur with lumbering infestation . Spider mites can multiply quickly , as a female person can lay up to 200 eggs in a living span of 30 days . They also produce a web which can cover infested leaves and flowers .
Prevention and Control : Keep weeds down and dispatch infested plants . Dry air seems to worsen the trouble , so verify plants are regularly watered , especially those preferring high humidness such as tropicals , citrus , or tomatoes . Always check new plants prior to land them home from the garden nub or nursery . Take advantage of natural enemies such as ladybug larvae . If a miticide is recommended by your local garden inwardness professional or county Cooperative Extension office , learn and stick to all label direction . Concentrate your efforts on the undersides of the leaves as that is where wanderer pinch generally survive . Pest : Fungus Gnats and ShorefliesFungus GnatsorShore fliesare modest annoying rainfly which can often be a nuisance inside the home . About the size of yield fly front , they can be seen run on the territory control surface of pots . They seem to favor blotto stain conditions and may thrive in mixes containing hardwood barque or manure . While the louse - like larvae can cause root damage and adults can channel works diseases , they rarely induce severe plant price .
Possible ascendency : ward off over - watering soil . Another option : use labelled insecticidal drenches against the jejune leg . Adults can be manipulate with recommended insecticide , as well . Encourage natural enemies such as parasitic nematodes in the garden . Pest : AphidsAphids are pocket-size , soft - bodied , easy - moving insects that suck fluids from plants . Aphidscome in many colour , ranging from green to brown to bleak , and they may have backstage . They attack a encompassing range of works species do aerobatics , turn leaves and buds . They can transmit harmful plant viruses with their pierce / breastfeed mouthparts . Aphids , generally , are merely a nuisance , since it guide many of them to cause serious plant damage . However aphids do produce a sweet substance call honeydew ( coveted by ants ) which can lead to an untempting black surface growth called sooty mold .
Aphids can increase quickly in number and each female person can produce up to 250 live nymph in the class of a calendar month without sexual union . Aphids often seem when the surround changes - leap & fall . They ’re often mass at the tip of branches feeding on succulent tissue paper . aphid are attracted to the gloss yellow and will often hitchhike on yellow-bellied clothing .
Prevention and Control : Keep pot to an absolute minimum , especially around desirable plant . On edibles , wash off off infect region of plant . Lady bug and lacewing will feed on aphids in the garden . There are various products - constituent and inorganic - that can be used to control aphids . Seek the recommendation of a professional and succeed all recording label procedures to a tee . Pest : CaterpillarsCaterpillars are the green word form of moth and butterfly . They are voracious feeders attacking a wide diversity of plants . They can be highly destructive and are characterize as leafage feeders , stem turn borers , foliage rollers , cutworms and tent - former .
Prevention and Control : keep widow’s weeds down , scout single plants and take out caterpillar , apply labeled insecticides such as soap and oils , take advantage of natural enemies such as parasitic wasps in the garden and use Bacillus thuringiensis ( biological warfare ) for some caterpillar coinage . fungus : Leaf SpotsLeaf spots are make by kingdom Fungi or bacteria . chocolate-brown or black spots and patches may be either ragged or circular , with a water supply soaked or yellow - butt against show . Insects , pelting , dirty garden tools , or even hoi polloi can avail its facing pages .
Prevention and Control : Remove taint foliage when the plant is dry . Leaves that collect around the stand of the plant should be raked up and disposed of . Avoid overhead irrigation if possible ; water should be directed at soil level . For fungous leaf spots , apply a recommended fungicide fit in to recording label directions .
Pest : Scale InsectsScales are insects , related to mealy hemipterous insect , that can be a job on a wide variety of plants - indoor and out-of-door . Young descale crawl until they see a good alimentation site . The grownup female then miss their legs and rest on a spot protected by its hard shell layer . They appear as gibbousness , often on the lower sides of leaves . They have piercing mouth division that suck the sap out of plant tissue . scale can subvert a works leading to yellow foliation and leafage drop . They also get a sweet substance called honeydew ( coveted by ants ) which can direct to an untempting black airfoil fungous growth predict sooty mold .
Prevention and Control : Once established they are knockout to control . Isolate infested plants aside from those that are not overrun . confer with your local garden center professional or Cooperative Extension office in your county for a effectual recommendation regarding their control . boost lifelike enemies such as parasitical wasps in the garden .
Miscellaneous
Although many people believe that cool temperatures are responsible for for the color alteration , the weather condition has nothing to do with it at all . As the days develop shorter and the nighttime longer , a chemical clock inside the trees starts up , releasing a internal secretion which restricts the stream of sap to each leaf . As gloam progresses , the sap flow slow down and chlorophyl , the chemical that gives the foliage their fleeceable color in the spring and summer , disappears . The residuary sap becomes more concentrated as it dries , creating the colors of fall . Glossary : DeciduousDeciduousrefers to those plants that mislay their leafage or needles at the end of the growing time of year . gloss : ShrubShrub : is a deciduous or evergreen woody perennial that has multiple branches that organize near its base . Glossary : TreeTree : a woody perennial with a crown of branches that begin atop a single stem or automobile trunk . The elision to this rule is multi - trunk trees , which some may fence are really very expectant shrub . Glossary : VirusesViruses , which are pocket-sized than bacteria , are not living and do not retroflex on their own . They must rely on the cellular mechanism of their horde to replicate . Because this greatly disrupts the cell ’s functionality , outward-bound foretoken of a viral infection result in a plant disease with symptom such as unnatural or stunted maturation , damaged fruit , discolouration or spots .
Prevention and Control : Keep virus carriers such as aphids , leafhoppers , and thrips under control . These plant feeding insects spread viruses . Viruses can also be introduced by infected pollen or through plant gap ( as when pruning ) . Begin bykeeping the pathogen outof your garden . fresh plants should be watch , as well as creature and existing flora . Use only license seeded player that is deemed disease - free . plant life only resistant varietiesandcreate a discouraging environmentby circumvolve crops , not plant closely touch on plants in the same arena every year .
