Established trees are drought tolerant. It looks great in the front or back yard of your home, as well as in parks, and in front of offices and professional buildings. With this guide on “How to Grow Magnolia Trees”, you’re on your way to growing a magnificent landscape plant.

Magnolia trees are propagated from seeds or cuttings.
Growing them from seed is quite involved and takes a lot of effort. Seeds are not viable once they dry out. So, you need to take seeds from an existing tree. This is done in the fall. The spent flowers produce a seed pod. The pods open up and you will find a bright red berry inside. Take the seeds from the berries before they have dried out.
Here’s how to grow magnolia trees from seed:
Cuttings are much easier. Take a cutting from the plant. Place it in a container with rich soil. Keep the soil moist. After several weeks, the cuttings will develop a root system. More on rooting plants from cuttings.
Trees grown from seeds can take as long as 15 to 20 years before you see the first Magnolia flowers. Trees grown from cuttings take much less time, but still, need years to the first bloom. As a result, most people buy young trees from garden stores.
Mature Magnolia trees are maintenance-free. Like most other trees, young saplings benefit from a little attention.
It is best to plant young trees in the spring.
Select a planting site that is in full sun. However, the trees tolerate partial shade. Also, plant it in a location where people can admire the beautiful spring blooms. That’s why so many homeowners grow magnolia trees in their front yard.
Young plants grow best in rich, organic, and well-draining soil. Dig a hole twice the diameter of the root ball. Loosen up the soil in the hole and mix in an ample amount of compost. Place the tree into the hole at the same depth that it originally was. Tamp down the soil, and water thoroughly. Water regularly during the first few months’ of growth to help its root system to develop. More on transplanting trees.
When grown in good soil, the trees do not need any additional fertilizer.
Ideal Soil pH: 5.5 – 6.0.
Like any other young plant growing magnolia trees benefit from occasional pruning. Prune the trees in the spring or early summer after the current year’s growth stops. Cut and remove any dead leaves and branches. You can also prune the tree to improve its shape.
There is no need to remove spent magnolia flowers. Allow them to die and fall off naturally.
If possible, avoid pruning live branches from mature trees. This can actually harm them.
Magnolia trees are fairly insect and disease resistant.
Potential disease problems include bark disease, nectaria canker, wetwood (bacterial), root rot in wet soils, and magnolia scale.
