Magnolia Magnolia 'J.c. Williams'

Water

For the Magnolia 'J.C. Williams', commonly known as Saucer Magnolia, it is essential to water the plant thoroughly, making sure the soil is evenly moist without being waterlogged. During the growing season in spring and summer, water it once a week with about 1.5 gallons per watering session, depending on the weather and soil drainage. If rainfall is adequate, reduce the frequency of watering. In hot, dry spells, you may need to water twice a week. Cut back on watering in the fall and water sparingly in winter, just enough to prevent the soil from drying out completely.

Light

Saucer Magnolia thrives in full sun to partial shade, with a preference for a spot that receives direct sunlight for at least four hours a day. Ideally, plant it where it will be sheltered from harsh afternoon sun, which can lead to scorching of the leaves, especially in Southern climates. East or west-facing locations with morning light or filtered afternoon light are excellent for promoting healthy growth and flower production.

Temperature

The Saucer Magnolia is hardy in a range of temperatures but performs best in conditions that do not exceed 95°F in the summer and do not drop below -20°F in the winter. The ideal temperature range for active growth is between 70°F and 85°F. Ensure proper mulching to protect the roots from extreme cold and avoid planting in locations where cold drafts and sudden temperature drops are common.

Pruning

Prune Saucer Magnolia to maintain its shape and remove any dead or damaged branches. The best time to prune is soon after the tree finishes blooming in late spring or early summer. Light pruning can be done every year, but significant pruning should be carried out less frequently to avoid stress to the tree. Always use clean, sharp tools to make precise cuts and minimize the risk of disease.

Cleaning

As needed

Soil

The best soil mix for a Magnolia 'J.C. Williams' should be rich, well-draining, and slightly acidic to neutral in pH (5.5 to 7.0). A combination of peat, compost, and coarse sand or perlite can improve soil structure and fertility.

Repotting

Magnolia 'J.C. Williams' should be repotted every 2 to 3 years, in spring before the growing season begins, or when it outgrows its pot.

Humidity & Misting

Magnolias, including 'J.C. Williams', prefer moderate humidity levels, but they are adaptable and do not require specific humidity conditions to thrive.

Suitable locations

• Indoor

  Place in bright indirect light, away from drafts, and water sparingly.

• Outdoor

  Choose a sunny spot, shelter from strong winds, and mulch annually.

• Hardiness zone

  7-9 USDA

Life cycle

The Magnolia 'J.C. Williams', commonly known as saucer magnolia, begins its life cycle with seed germination after stratification, which occurs when seeds experience cold temperatures that break dormancy. Upon germination, the seedling grows through its juvenile phase developing a root system and foliage. As it matures, the saucer magnolia enters the vegetative stage, where it increases in height and width, growing sturdy branches that will support its large flowers. The reproductive phase follows, with the magnolia producing large, fragrant, showy flowers typically in early spring before the leaves fully expand. After pollination, usually by beetles attracted to the flowers, the tree sets seeds encased in cone-like fruit that mature and release seeds to begin the next generation. As a woody perennial, the saucer magnolia then enters a period of senescence in old age, where growth slows and the plant may begin to decline in vigor before eventually dying.

  Spring-Early Summer

• Magnolia 'J.C. Williams', commonly referred to as Magnolia, can be propagated by several methods, but the most popular and successful way is through semi-hardwood cuttings. This is typically done in late summer after the current year's growth has begun to mature and the wood is semi-ripe. You begin by selecting healthy, semi-hardwood branches that are about pencil-thick and 6 to 8 inches (15 to 20 centimeters) long. Cuttings should have at least two to three sets of leaves and should be taken early in the morning to ensure they are full of water. The leaves on the lower half of the cutting should be removed, and the cut end can be dipped in rooting hormone to encourage root development. The treated cutting is then planted in a well-draining medium, kept moist, and ideally placed in a propagator or under a plastic tent to maintain high humidity until roots have developed. It's important to avoid direct sunlight, which can overheat and dehydrate the cuttings.
