large-flowered magnolia

Large-flowered magnolia should be watered deeply twice a week in summer, so that the soil stays moist but not wet. To do this, water thoroughly until the water begins to run from the drainage holes at the bottom of the pot. When temperatures drop in winter, reduce the watering schedule to once per week. Always check the moisture level of the soil before watering, and never let the soil dry out completely. Give the plant an extra drink of water during hot, dry stretches.

Large-flowered magnolia should receive a minimum of 3-4 hours of direct sunlight per day. During peak months, between April and August, the plant can tolerate up to 8 hours of direct light. While the plant can tolerate full sun in the summer months, during periods of intense sunlight the magnolia should be given partial shade. On hot summer days, the plant should be protected from strong midday sun. During winter months, when sunlight is typically less intense, the large-flowered magnolia should receive at least 2 to 4 hours of direct sunlight every day.

The best time to prune large-flowered magnolia (Magnolia grandiflora 'Edith Bogue') is in late winter to early spring before new growth emerges. Prune lightly no more than 1-third of the total canopy. Cut off dead, diseased or damaged branches as well as excess volunteers. If you determine that the plant needs structural pruning, plan to do more aggressive pruning over a 2-to-3-year period. Doing too much drastic pruning at 1 time can cause the plant to re-sprout in a disorganized manner.
