Planting
Timing: The best time to plant a saucer magnolia is in the fall or early spring. This allows the tree to establish its roots before the stress of summer heat or winter cold.
Planting Steps:
- Dig a hole that is twice as wide and just as deep as the root ball.
- Remove the tree from its container and gently loosen the roots.
- Place the tree in the hole, ensuring that the root ball is level with or slightly above the surrounding soil.
- Backfill the hole with the original soil, mixing in compost if necessary.
- Water thoroughly to settle the soil and eliminate air pockets.
Watering
Proper watering is crucial, especially during the first few years after planting. Saucer magnolias prefer consistently moist soil but do not tolerate waterlogged conditions.
Watering Tips:
- Water deeply once a week, providing about 1-2 inches of water.
- Mulch around the base of the tree with a 2-3 inch layer of organic mulch (like bark or wood chips) to retain moisture and regulate soil temperature. Keep mulch a few inches away from the trunk to prevent rot.
- During dry spells, increase watering frequency to ensure the soil remains moist.
Feeding
Saucer magnolias benefit from regular feeding to support their growth and flowering.
Fertilizing Tips:
- Apply a balanced, slow-release fertilizer (10-10-10) in early spring before new growth begins.
- Follow the manufacturer’s instructions for the appropriate amount based on the tree’s size and age.
- Avoid over-fertilizing, as this can lead to excessive leaf growth at the expense of flowers.
Pruning
Pruning helps maintain the shape of the tree and removes dead or diseased wood.
Pruning Tips:
- The best time to prune is right after the tree has finished flowering, usually in late spring or early summer.
- Remove any dead, damaged, or diseased branches first.
- Thin out crowded branches to improve air circulation and light penetration.
- Avoid heavy pruning, as this can reduce flowering and stress the tree.

Pests: Saucer magnolias can be affected by scale insects and aphids. Regular inspection and early intervention are key.
- Scale Insects: These appear as small, raised bumps on the branches. Treat with horticultural oil or insecticidal soap.
- Aphids: These tiny insects suck sap from new growth, causing leaves to curl and distort. Spray with insecticidal soap or introduce natural predators like ladybugs.
Diseases: Common diseases include powdery mildew and leaf spot.
Leaf Spot: This appears as dark spots on leaves and can be managed by removing affected leaves and applying a fungicide.
Powdery Mildew: This fungal disease appears as a white powdery coating on leaves. Improve air circulation and treat with a fungicide if necessary.
