It is recommended plant the magnolia at early fall to promote rooting before winter and therefore recovery in spring.

For the persistent species, you can easily plant in the spring.

Evergreen magnolias can reach 20 meters in height and should therefore be planted away from homes.

Deciduous magnolias are smaller in size (around 5-6m tall) and can even be planted along a wall for training.

  • Straw the base of the tree to retain moisture and prevent weed growth.

Magnolia maintenance

The deciduous magnolia requires little maintenance and is even very resistant to diseases, although a few tips will help you have better flowering:

  • Mulch the foot with bark to maintain the level ofacidity it needs
  • Mulching also brings some moisture to the soil, which the magnolia tree will benefit from during the warmer months.
  • Yes it does not bloom, remove a little soil up to the roots and top up with heather soil

Let it be lapsed (Magnolia soulangeana) or persistent (Magnolia grandiflora), the magnolia tree requires little care when properly installed and will adorn your garden for years to come.

Pests are few in number to attack magnolias although there are sometimes a few aphids and even more rarely red spiders in summer.

Magnolia growth

Magnolia growth is believed to be normal, neither fast nor slow. It will take several years for it to reach full adult size.

By the time it reaches 5-6 m in height, a little more for some varieties, it will have reached its adult size.

The growth of magnolia can be speeded up by giving it regular fertilizer for flowering shrubs.

Magnolia size

No pruning of the magnolia is really essential but if you wish reduce or balance or reshape the antlers, do it after flowering or in the fall.

Pruning possible in winter to balance the antlers. Note that what most characterizes the magnolia is its natural form and that it is therefore important to preserve it by avoiding unbalancing the branches.

  • Remove dead branches and more fragile branches as you go.
  • Do not prune the magnolia in early spring otherwise you will not have flowers
