About this plant
This is a spreading rather shrubby tree. The great joy of this magnolia is its incredible flowers. They are generally viewed from beneath the branches. So walk beneath their spread and look up. The flowers appear to have alighted with white petals spread like wings about the mound of furled stamens with a pale green stigmatic column at their heart. The flowers may move and nod and emit a delectable lemon fragrance that is most apparent around dusk. The leaves are of medium size, somewhat oblong with down on their underside, and glaucous green on their upper. There should be flowers from May through to August, never born profusely, but a strong individual presence. Red fruits may follow. Plant on a bank for best effect. It should take some lime in the soil if there is plenty of moisture available.

Feed young plants with slow release fertiliser
Spread a slow release fertiliser around the base of the plant to the edge of the foliage spread, so that it can feed the roots. It is helpful for this to be applied for several years.
This is a simple way to provide a nutrient boost until the plant becomes well established.
Spring-Autumn · Outdoors
Water to keep the soil moist
For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.
Without regular watering some plants never fully regain their beauty.

Trim the plant
Trim the plant to give it a general tidy. This includes removing any lengthy or awkward shoots that make the plant look visually less attractive. Remove any spent flower heads at the same time.
Planting & general
Outdoor planting · Planting
Add root growth stimulant to the planting hole
Mycorrhizal fungi helps roots establish quickly, so they absorb water and nutrients more efficiently. It comes as a powder, granule or gel. Add to the planting hole or container, and to the plant's rootball before planting in the hole. For "bareroot" plants use a gel.
