The southern magnolia can reach heights of 90 feet and grows dark green leaves and large, white, and fragrant flowers. Ideal for subtropical environments, the southern magnolia is a slow growing and majestic addition to any garden. Despite being an evergreen, the southern magnolia drops its leaves year-round, but this tree is truly worth the price.

Sweetbay Magnolia (Magnolia virginiana)

Planting Magnolia Trees

It is essential to plan where to plant your magnolia tree ahead of time. The location where its planted will help keep your magnolia alive. If in an area that expects colder winters than your magnolia can handle, try to choose a spot shielded from winds. Most magnolias need between 12 and 24 feet of space to thrive. Follow the instructions below to properly plant your magnolia tree.

  1. Remove the first two inches of soil and store in a separate container. This will be used later in the planting process.
  2. Dig a hole at least 1.5 times wider than the root container or ball and slightly shorter than the root.
  3. Place the root ball or container in the middle of the hole. The upper root should be slightly above the ground.
  4. Fill in the hole with the topmost soil you have on the side. Keep the top of the root ball uncovered. Other methods include partially filling the soil in, irrigating, then allowing the water to fully drain before filling in the hole completely.
  5. After planting, water two to three times a week for the first 6 months, and then weekly once established. Use 2 gallons of water per inch of the magnolia’s trunk diameter.
  6. Fertilizer can help magnolia tree growth, but it is not necessary.

Growing Magnolias

One of the best features of Magnolias is their ease of growth. These trees are easy to care for and can live for centuries. Below is all you will need to know for your magnolia tree needs.

  • Soil and Watering – The majority of magnolias prefer slightly acidic soils for growth. Try to keep your soil well drained and moist. Once a magnolia reaches adulthood, it becomes hardier and can resist more changes in its soil.
  • Light – Most Magnolias thrive in full sunlight or partial shade. However, if the magnolia is growing in a warmer and dry climate, then extended shade from the sun might be necessary. In addition, attempt to keep your magnolia away from strong winds – exposure to heavy wind can tear flowers or even remove branches.
  • Fertilizer – Young magnolias need some fertilizer at the time of planting. However, once a magnolia is established and blooming, then no additional fertilizer should be needed.
  • Pruning – Whether or not to prune your magnolia depends on your needs. To keep your magnolia compact, prune after the tree has finished blooming in the beginning of summer. Otherwise, no pruning is necessary other than the odd shape up or damaged limb.
  • Garden Pests – Luckily, magnolias are resistant to almost all pests from a garden.
