Magnolia grandiflora care

Magnolia grandiflora asks for little maintenance, resists diseases splendidly, though a few tips can trigger a better bloom:

Magnolia grandiflora demands little care when well established, gracing your garden for many years. Few pests target magnolia grandifloras, though sometimes you might spot a few aphids and more rarely red spider mites in summer.

Pruning magnolia grandiflora

Pruning isn’t essential but if you wish to reduce, balance or reshape branches, do it at winter’s end, around March-April.

Pruning to balance branches should be done in the last days of winter, before buds start forming. Remember, magnolia’s natural shape is its trademark, so aim to preserve it as you prune to retain symmetry among branches.

• Get rid of dead branches and weakest ones as they come.

Good to know about evergreen magnolia

Magnolia isn’t just a pretty tree, it’s got a rich history and even inspired a few artists! It’s named after Pierre Magnol, a French botanist who was quite renowned in his time. This tree is native to the United States.

People love it for its stunning summer bloom and its distinct fragrance. Magnolias come in tree and dwarf varieties, which are great for small gardens.

Now, there is one fact we must get straight: there are two major types of magnolias.  One is evergreen, the other deciduous:

• Evergreen magnolia, also known as large-flowered Magnolia or Magnolia grandiflora. Flowers appear in summer, forming large tulip-shaped inflorescences around 8 to 10 inches in diameter (20 to 25 cm).
• Deciduous magnolias, also known as Soulanges’ Magnolia or Magnolia soulangeana. These bloom in early spring, before leaves unfurl, which covers the entire tree with flowers.

Smart advice

Maritime pine bark will provide acidity this tree needs to thrive and help it retain moisture. For added effectiveness, mulch in summer with a layer about 2 inches deep.
