The Magnolia grandiflora, also known as the evergreen magnolia, is a popular ornamental tree. Whether hardy or sensitive varieties, they all need a bit of care.

How should you water this magnolia species?

The Magnolia grandiflora is a flat-rooted plant and has large leaves that evaporate a lot of water. For this reason, it is dependent on a regular water supply from above. To avoid having to water them all the time, they should be mulched and/or underplanted with winter and spring flowering plants such as snow cups and hyacinths.

This magnolia should be watered with rainwater so that the soil does not dry out. Especially in summer, the soil must be kept evenly moist. But even in winter there is no need to water because it is an evergreen plant.

Does she have high nutritional needs?

Yes she has. A deficiency is noticeable, for example, when a lot of leaves are dropped. In the bucket, this plant should be supplied with complete fertilizer every week from March to September. Outdoors, three doses (March, May, June) with compost are sufficient.

Do you have to cut them?

She looks best without a cut. But if it has lost its shape or branches have broken off due to a storm, a cut makes sense. It should be done after flowering.

Should they be protected from frost in winter?

Young specimens in particular should receive winter protection. First, apply a layer of bark mulch to the root area. Leaves, straw and twigs come on top. Trees should be covered with fleece in the trunk area.

How can it be multiplied?

The Magnolia grandiflora can be propagated by mosses, cuttings, layering and seeds. Sowing works as follows:

  • Harvest seeds from the mature pods in fall
  • Remove seed coat
  • Stratify in the fridge for 2 to 3 months
  • Soak in water for 2 days
  • sow in a pot (cover with soil)
  • pour on
  • put in a warm place
  • plant out in May

tips and tricks

Always cut the branches to the base. Leftover stubs quickly lead to broom growth.
