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
– 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 pruner
and remove as many growing tips as
possible, prune deeper into the branch in
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.
