– Use Southern Magnolia D.D. Blanchard as a foundation accent only when you will be able to place it 15 ft from the foundation of a home, not because the roots are problematic but because of the multitude of lateral growing
branches that will within 10-20 years of being planted in the landscape be growing 12+ feet from the trunk. Magnolia D.D. Blanchard can be planted closer to structures where you will be clearing the lower branches up and

Care of Southern Magnolia D.D. Blanchard:
– Although Magnolia trees can be planted from a container into the landscape any time of the year in our North Florida | Jacksonville | St. Augustine area landscapes, Magnolias root systems
are very wide for their size making transplanting sometimes difficult, so if you decide to move one from one location to another in
the yard be sure to do it in winter or spring for the best result possible.
– Water every day during the establishment period, See watering your newly planted trees for more information. Magnolia’s must be
watched for the first one to two seasons after being planted
or transplanted in the landscape and supplemental water supplied in any time of drought. They are slower to establish themselves into
the landscape than many other trees and should be watered
well once a week when local rainfall is scarce.
– Magnolias respond well to pruning, when shaping a younger tree
they should be pruned 6 inches deeper than where you would like to see the re-growth appear. Everywhere you trim the tree will sprout new growth and begin to branch out and fill in. So if you have a scarcely foliated Magnolia tree get out the pruners and remove as many growing tips as possible, prune deeper into the branch in
scarcely foliated areas to get them to branch out and fill in the gaps.
– Magnolias have lots of branches all though they will be smaller in diameter in comparison to other larger growing shade trees like an Oak. Prune out the occasional occurrence of a branch at a sharper angle than 45 degrees or if damaged etc. by removing the branch all the way back to the trunk.
– Provide a 1 ft diameter circle of mulched area where grass is kept from growing for each inch of caliper (or diameter) of trunk
measured 4 inches from the ground level.
– Fertilize each spring with a mixture of Milorganite and a slow release poly coated plant food
such as Osmocote or Stay Green general purpose plant food, sprinkling the fertilizer around the mulch circle underneath the
foliage of the tree.
