Growing Little Gem Magnolia in NZ: Care and Planting Tips

Little Gem Magnolia

The Little Gem Magnolia, a cultivar of Magnolia grandiflora, is a popular choice for gardens due to its smaller size and stunning, fragrant white flowers. Unlike its larger relatives, Little Gem is well-suited for smaller garden spaces, making it a favourite for urban gardeners. But what about the common concern: "Are Little Gem Magnolia roots invasive?" Fortunately, their root system is generally non-invasive, making them a safe choice for planting near structures.

Caring for Little Gem Magnolia

Regular watering is essential, especially during the first few years as the tree establishes itself. However, avoid overwatering. Fertilize the tree with a balanced slow-release fertilizer in spring to encourage healthy growth. Pruning is minimal, primarily to remove dead or damaged branches and to maintain the desired shape. Prune after the flowering season to avoid cutting off buds.

Common Little Gem Magnolia Problems

While generally robust, Little Gem Magnolias can face a few challenges:

• Pests: Keep an eye out for pests like scale insects. These can be managed with an appropriate agrichemical.
• Fungal Diseases: Ensure good air circulation and avoid overhead watering to prevent fungal issues.

Planting Little Gem Magnolia

Choosing the right location is crucial for the healthy growth of Little Gem Magnolia. These trees thrive in full sun to partial shade, so select a spot in your garden that receives plenty of sunlight. Ensure the soil is well-draining, as waterlogged conditions can lead to root rot.

Planting Process

• Dig a Hole: Start by digging a hole that is twice as wide and just as deep as the root ball.
• Position the Tree: Place the tree in the hole, ensuring that the top of the root ball is level with the ground.
• Backfill and Water: Fill the hole with soil, water thoroughly to eliminate air pockets, and apply mulch to retain moisture.
• The Plant Company also recommends the trees are staked to protect them from wind and this helps create a better formed tree overall.

Using Little Gem Magnolia as a Hedge

Little Gem Magnolia can also be used to create an attractive hedge. Plant them about 1.5 to 2 metres apart to allow for growth while forming a dense screen. Regular pruning will help maintain the desired height and shape, as well as keeping them bushy.
