The Southern magnolia ( Magnolia grandiflora ) is breathtaking at its full maturity date : The deep green , glossy leave of absence cover graceful limb . Its branches unfold outwards to create a lush , full tree with a formal look . The prominent , fragrant white blossoms that cover the tree in late spring and early summertime are show-stopper . Magnolia trees grow at a relatively firm pace in their preferred climate , which ranges from warm to semitropical , but their rate of ontogenesis is affected by stain character and weather conditions . The rate of maturation will be dull in cool climates .
Types
There are three type of growth involve in measuring the speed of growth of a magnolia Sir Herbert Beerbohm Tree . The first is height , the most obvious indicator of growth , and it plainly indicates the entire measuring of the Sir Herbert Beerbohm Tree from the uppermost offset to the base of the trunk where it meets the ground . The second type of growth is trunk growth , which may be quantify by the increase in either the circumference or diam of the trunk . The third type of growth is in spread , the full area that is direct up by the branches of the tree diagram . Some tree have an erect ontogenesis pattern : their branches will taper off toward the ’s Tree wind , creating a triangular shape . Other Tree , including the magnolia , have a spreading growth pattern : their offset outwards from tree top to bottom without a distinct tapering pattern .
Time Frame
The Southern magnolia grows at a rate know as middling tight in the gardening world ; in normal growing condition , it will average a full foot of outgrowth in top every twelvemonth . The magnolia is a medium - sized tree diagram , meaning that its full tiptop ranges from 35 to 60 feet and its spread can make about 15 foot around . Magnolias usually average about 0.2 inches of diam ontogeny per yr . Growth slow down when the tree has maturate to about 50 years onetime .
Geography
The speed of growth of a magnolia tree diagram will motley calculate on where it is being grown . As the name indicates , the magnolia is a Southern indigene . It grows best ( and thus , fastest ) in the Southeast of the United States : the lower parts of Texas , Louisiana , Mississippi , Alabama and Georgia , and the Florida Panhandle . These regions vagabond from strong temperate to semitropical . In such areas , the growth of a Magnolia tree should carry on along at an average of 1 fundament in height per twelvemonth under normal develop condition . originate a magnolia tree in cool zone is potential , but the growth rate will be much slower .
Considerations
Other broker that affect the speed of ontogenesis of a magnolia include soil precondition and weather conditions . The magnolia prefers a robust soil with a good degree of wet , such as that found along streams and in swamp . Heavy mud grease can slow theme growth , thus belittle top development . similarly , a filth that is too sandy , rough and wanting in nutrients will slow the overall emergence charge per unit as well . Weather is the other factor : Though the magnolia is patient of of heat , it still needs water in monastic order to uprise . Drought will belittle growth ; during periods of drought , water your magnolia weekly until the soil around it is soaked .
Expert Insight
Winter drouth can slow down the leap - time growing of a magnolia Sir Herbert Beerbohm Tree , say Kenneth W. Outcalt ( USDA Forest Service ) . Extreme winter drouth can cause the tree to die back in wintertime . In springtime , the tree diagram has to do a great deal of " catching up " to attain its former height ; it may not produce any extra growth in height or spread for the yr . To keep growth on track , remember that a magnolia tree needs water even during the stale winter month . During winter drouth ( absence seizure of snow or rain ) , water bimonthly , dowse the ground around the tree . Outcalt also posit that a particular variety of the Southern magnolia , M. grandiflora gallissoniensis , is said to be cold - dauntless and may produce good growth in the cooler climate .
