Here ’s what I ’ll wrap up :
What You’ll Learn
Before we dive into caring for this plant , let ’s take a look at its origin tale .
Cultivation and History
The original Freeman maple was created when Oliver Myles Freeman hybridized ared maple , A. rubrum , and a fluent maple , A. saccharinum , in 1933 .
Freeman was a botanist at the National Arboretum who bred native trees to create exciting new crisscross .
Not only did he create the Freeman maple , but he also breed asouthern magnolia ( Magnolia grandiflora)and asweetbay magnolia ( M. virginiana)cross to create the ‘ Freeman ’ hybrid , which is still popular today .
Freeman ’s maple combines the best of both parent species , with strong branch attachment and beautiful gloam leafage thanks to the red maple , and the degenerate , vigorous maturation of the silverish maple .
Depending on the cultivar , these trees can grow four time faster than the reddened maple .
There are actually innate crosses of the silver and reddened maple out in the wild , sinceAcertrees hybridize easily , but Freeman maples were carefully school to merge all the best calibre of the two species .
The original Freeman maple grows between 40 to 60 feet magniloquent and about one-half as panoptic , though many of the New cultivar stay much minor .
They generally have an upright , pyramidic form , but cultivars can change , with some having rounder or more narrow-minded forms . At the center is a strong , straightforward automobile trunk with grey , fissure bark .
The leaves grow opposite each other and each has a distinctly toothed security deposit and five deep lobes .
I love take in them move in the cinch because the topsides are medium green , while the undersides have a silver hue . It gives a kaleidoscope - like effect when the leaves are locomote . In the fall , the leaves become bright orange or red with paler underside .
In the leaping , red clusters of flowers form at the ends of the branch . These invisible flush after develop into source pods known as key fruit .
Samaras are the two - wing , helicopter - like pods that twirl to the ground in the springiness and summer .
The original Freeman maple was a male person , so it did n’t form samaras , but these Tree can also have female office even if they are described as male person .
Freeman Maple Propagation
As hybrids , you ca n’t set off these trees from seed and anticipate to grow an precise replication of the parent plant . That leaves you with a few other sound options .
you’re able to propagate via root word cuttings , tune layering , graft , or you’re able to purchase a potted specimen to transplantation .
graft involves taking a branch from the tree and seize it to a rootstock to maturate a industrial plant that compound the characteristics of both parents .
Air layering require remove the bark to encourage the tree to develop roots , and conduct stem newspaper clipping is the process of removing a branch and plant it in a growing medium .
Once it forms roots in the medium , you could transplant it out into the garden .
Ourguide to arise maple explain all the details about each different extension method .
Transplanting
The easiest way to get take up is to purchase a sapling from a garden center or greenhouse .
To do this , dig a kettle of fish about two to three multiplication the breadth of the container the flora is presently growing in .
You do n’t ask to dig up any deeper than the container unless you really want to . Gently off the plant by grab it at the base , close to the soil , and wiggling it out of the pot .
If it really resists , you might need to use a knife or scissors to reduce the container rather than risk damage to the radical . Once it ’s gratuitous , loosen up the roots if they are tightly bound together .
Place the industrial plant in the hole at the same depth it was in the pot – not deep – and endeavor to guide the roots out and away from the bole .
Backfill the hole with the removed grime . Water well and tot up more soil if it resolve .
How to Grow Freeman Maples
As is the character with most maples , well - draining soil is of the essence . Your tree will not fly high if it ’s in waterlogged soil . That said , it can tolerate weighed down Lucius DuBignon Clay and very casual implosion therapy .
In plus to being well - debilitate , ideally the grunge should be organically - rich and slightly acidic to neutral , with a pH between 5.5 and 7.5 .
Any billet with full sun or partial tincture will work , though the tree will probably grow so tall that it will eventually outmatch nearby trees .
implant young trees in a location that receive at least four hours of direct sun per day . Six or more is ideal .
Once established , Freeman maples are drought resistant , but they need regular moisture for the first class or two . Add water when the top in or two of dirt dries out . The soil below should feel like a well - wrung - out leech .
After that , you may rely on nature to provide the moisture unless you have a retentive , hot , dry stretch .
Before you feed your plant , test your grime . These Tree do n’t need a lot of fertilization , so your dirt might be absolutely adequate .
Or it might have plenty of nitrogen but not enough potassium or daystar , so an all - aim plant food for thought would n’t be the right convulsion .
Every few years , it ’s a good melodic theme to do a territory test and meliorate according to the results . you could arrive at out to your local extension office or use a home test kit .
I can guarantee for the MySoil Test Kit . You send out in a sample to the lab and they ’ll give you a detailed psychoanalysis that you may access online .

Growing Tips
Pruning and Maintenance
You do n’t need to prune these Sir Herbert Beerbohm Tree as they maintain an attractive shape without pruning .
However , if you see any broken , diseased , hard pest - infested , or deformed branches , take them out .
You should use the three - cut pruning method if you need to take away big limb .
This involves making a cut on the underside of the limb about nine inches from the trunk . Make the straight through about a third of the branch .
This cut prevent damage such as barque tearing or ripping as the limb come away from the tree .
Next , a few inches nigher to the proboscis , saw through the branch from the top downwards , and you ’ll be left with a stump .
discover the offset leash , which is a swollen area attached to the trunk from which the branch emerges .
Trim the stump at the offshoot collar , not reduce through it , but as closely as you may while go out the collar intact .
Smaller branches can be snipped off using pruner .

Managing Pests and Disease
Freeman maple are broadly problem devoid . As long as you plant them in the right placement and provide appropriate urine , most of the clock time your tree will take care of itself without any trouble .
Now , here ’s the thing . I hate it when experts say stuff like that because it make me feel like I did something awry if my supposedly sturdy tree is macabre .
That ’s why I want to add that sometimes issues bechance and even the most cautiously naturalize Sir Herbert Beerbohm Tree can be chatter by cuss or pathogen . That ’s just the fate of the draw .
If you catch an infestation or infection early on , the chances are good the tree diagram can recuperate . Let ’s tattle about the pests you might encounter , first .
Insects
worm trouble are most common on untried trees that are still becoming established in the garden .
An plague can promptly become a serious problem on a midget little flora . The good tidings is that it ’s ordinarily much easier to deal with pests when they ’re in a little area rather than on a 70 - foot - tall Sir Herbert Beerbohm Tree .
Cottony maple scale of measurement ( Pulvinaria innumerabilis ) and cottony maple leaf scale ( P. acericola ) love maples and boxelder trees ( Acer negundo ) , as well as livid ash ( Fraxinus americana),dogwood ( Cornusspp . ) , beech ( Fagusspp.),apple ( Malusspp.),oak ( Quercusspp.),linden ( Tiliaspp.),elm ( Ulmusspp . ) , and black locust ( Robiniaspp . ) .
If you have any of these metal money in your landscape painting in addition to your Freeman ’s maple , your hazard of experiencing an plague are increased .
The first time you encounter these pests , you might mistake them for symptoms of a disease or some kind of funky ontogenesis .
That ’s because the insects cluster in large chemical group and do n’t move much . They ’re covered in a waxy coating that makes them look more like a cluster of waxy lumps .
Their testicle sacs look like fuzzy or cottony clean growth . They are circular balls that can be half an inch long and all-inclusive .
Cottony maple leaf scale sacs appear on the undersurface of leaves while the pocket of cottony maple scale appear on stems and limb .
As the sapsucking insects provender , they can make yellow stippling on the leaf , branch dieback , and even tree dying .
You ’ll also retrieve mucilaginous honeydew , which is their secretions , all over the leaves and on anything below the tree diagram .
The populations tend to intumesce one year and disappear the next , but if you see a large number of egg masses , assume you ’ve get a giving infestation and this job is more than just an plaguey nuisance and should be addressed .
Avoid using chemical pesticides , as these also kill the insects that typically keep these pest in check .
Parasitoid ichneumonid wasps , gentlewoman beetles , and lacewings all fertilize on scale .
Insecticidal soap is in force against the crawlers , which is the nymph phase of the pest . Knock off the egg sacs with a strong stream of water .
Then , spray the tree every few weeks with insecticidal soap .
Monterey Insecticidal Soap
Grab some Monterey Insecticidal Soapat Arbico Organicsin a 32 - ounce ready - to - spray bottle .
The Japanese leafhopper ( Japananus hyalinus ) get in in North America in the late 1800s and has made a repast of plant in theAcergenus from Canada to Mexico ever since .
While it was in the beginning found onJapanese maple , it will also feed on otherAcerspecies and hybrids , include Freeman .
The leafhopper has a yellowish - green head , a brown consistency , and translucent wings with rusting - chocolate-brown bands .
The females are about three - sixteenth of an inch long and the Male are just slightly brusk .
The eggs , which are place in the barque , crosshatch in the spring . The nymphs , which go through five ecdysis , start feeding on the leave of absence as presently as they hatch .
After the five moltings , they come forth as adult and the hertz repeats . look on the distance of your growing time of year , there might be two generation each class .
When there is a large infestation , you could find out the eating activity , it can be that vivid .
fortuitously , these cuss are n’t repellent to pesticides , so any Cartesian product that contains pyrethrins will down them off .
Spray the tree once every two weeks while the pest are present using a product like Monterey Bug Buster - O.
Monterey Bug Buster - O
It’savailable at Arbico Organicsin eight- or 16 - ounce sprayer bottles .
There are two type of eriophyid gall mites that feed on maple . The first is the bladdergall jot ( Vasates quadripedes ) and the spindlegall mite ( V. aceriscrumana ) .
You ca n’t see the blank or clear microscopical mites themselves .
Their feeding initially causes depressed dots on the surface of the leaf followed by pouch - like green rancor formations in the same domain .
The mite live in these insolence , which step by step move around red , and when the pests suppurate , they lay eggs , leave the gall , and find a new foliage to infest . Then they overwinter in the bark . In plus to the unsightly galls , they also cause leaf distortion .
Populations fluctuate twelvemonth to class , with a tree being heavily infested one twelvemonth and nary a hint in quite a little the next .
The symptoms are wretched and severe to control , but the mites really just cause a cosmetic job .
Predatory jot will help keep the pests under control , and if you ’re desperate to stop the symptoms , you’re able to spray the body and branch with a product that contains pyrethrin in the springtime as soon as the atmospheric condition starts warming above freezing .
Repeat every two week for six weeks .
The goal is to kill the grownup as they move from the barque to the leaves as this is when they ’re most vulnerable .
rationalize off leaves as before long as they begin showing symptom can also help foreshorten populations . Put the leave of absence in a certain bag and dispose of them in the trash .
Disease
tree in theAcergenus are susceptible to verticillium wilt , so it would n’t be bonny to say that Freeman maples are immune , but they are rarely impress by this disease .
Its because of coinage of fungi in theVerticilliumgenus .
Still , be on the observation tower for sudden wilt , even if you bang that the tree has received enough piss . Usually , it wo n’t be the intact Sir Herbert Beerbohm Tree that will droop but a few branches or perchance a section .
Sometimes the tree will neglect leaves or have a general ailing coming into court .
If you scratch off the barque on the trunk or a symptomatic branch or branchlet , you will see immature streaks . If you see both the green streaks and wilting , chances are highly gamey that it ’s vert , as this disease is commonly known .
If that ’s the case , remove diagnostic branches and support the tree with appropriate H2O and fertilizer .
You do n’t need to remove it because the pathogen that causes this disease is already in the stain where it can live without a host flora , so it wo n’t help to take it out at this stop .
However , if the tree diagram is in speculative shape , it wo n’t go back and removal is probably upright .
If you determine to establish another tree , it will necessitate to be a resistant specie like birch ( Betulaspp . ) , dogwood ( Cornusspp.),ginkgo ( G. biloba),crabapple ( Malusspp.),red oak ( Quercus rubrus ) , orwillow ( Salixspp . ) .
Best Uses for Freeman Maples
As a tincture tree for a lawn , or in Japanese , cottage , or rainwater garden , it ’s concentrated to work over the Freeman maple thanks to its tough nature and beautiful growth .
The more erect cultivar are complete as street or parking lot trees .
They will also wreak forbonsai , and I make love to use the branch in prune flower arrangements in the fall .
Since these Sir Herbert Beerbohm Tree can tolerate both drouth and occasionally pixilated soil , they are an excellent choice for challenging areas where other metal money will fail to thrive .
