Fig 'Magnolia'
Bay Fig Magnolia Tree (Magnolia grandiflora) Overview
The Bay Fig Magnolia (Magnolia grandiflora) is a stunning, evergreen tree native to the southeastern United States, particularly along the Gulf Coast and in parts of the southeastern U.S. Its glossy, dark green leaves and large, fragrant white flowers make it a popular ornamental tree in warmer climates. Known for its resilience and beauty, the Bay Fig Magnolia is also commonly referred to as the Southern Magnolia or simply Magnolia. The tree’s leaves are thick and leathery, with a slightly fuzzy underside, and its large, waxy blooms appear in late spring or early summer, giving off a sweet, citrus-like fragrance. The flowers are followed by distinctive cone-like seed pods, which mature into reddish-brown fruits.
Taste Profile (Fruit)
While the Bay Fig Magnolia is primarily grown for its ornamental qualities, the seeds within the tree’s cones are technically edible, although they are not commonly consumed in culinary applications. The seeds are small and somewhat sweet, though they are not usually eaten raw. In traditional uses, the fruit and seeds have been used by indigenous peoples, but the tree is more renowned for its beauty and fragrance than for its fruit.
Best Growing Environment
The Bay Fig Magnolia thrives in warm, humid environments and is best suited for tropical and subtropical regions. It prefers moist, well-drained soils that are rich in organic matter, and it does well in slightly acidic to neutral soil (pH 6.0-7.0). The tree is native to regions that experience frequent rainfall and mild winters, making it ideal for planting in areas with warm temperatures and sufficient moisture. It is also somewhat tolerant of coastal conditions, as it can withstand salt air and occasional drought once established. Bay Fig Magnolias are relatively adaptable and can be grown in a variety of soil types, including clay, loam, and sandy soils, as long as drainage is good.

- Bull Bay (in some regions)
Average Height and Growth Rate
The Bay Fig Magnolia is a large tree, typically growing to 60-80 feet (18-24 meters) tall in ideal conditions, though it can reach up to 100 feet (30 meters) in its native habitat. It has a broad, pyramidal shape and can spread as wide as 40-50 feet (12-15 meters) in mature specimens. The growth rate of the tree is moderate to fast, typically growing around 1 to 2 feet (30 to 60 cm) per year when young. However, its growth rate can slow as it matures, particularly if the tree is grown in more challenging conditions, such as poorer soils or insufficient sunlight.
Sun Requirements
Bay Fig Magnolias require full sun to partial shade for optimal growth, though they will generally perform best when they receive at least 6 hours of direct sunlight per day. While they can tolerate some shade, particularly in hot climates, they will not flower as prolifically or grow as vigorously in shaded conditions. Full sun encourages the best flowering and the thick, lush green foliage for which the tree is known.
Cold Hardiness
While the Bay Fig Magnolia is relatively hardy compared to other magnolia species, it is still sensitive to freezing temperatures. It is best suited to USDA hardiness zones 7-10, which include regions of the southeastern U.S. and parts of the Gulf Coast, where the climate is mild and frost is rare. The tree can tolerate occasional cold snaps but can suffer damage if exposed to extended periods of freezing temperatures. In regions where temperatures regularly fall below freezing, the tree may struggle to thrive, and frost can damage its leaves, flowers, and young growth.
Water Requirements
Bay Fig Magnolias prefer moderate to regular watering, especially during the warmer months when they are actively growing. They do not tolerate dry, drought-like conditions, particularly when young. However, the tree is relatively drought-tolerant once it is fully established. It is essential to water the tree deeply, especially during periods of prolonged heat or low rainfall, to encourage deep root growth. The tree also appreciates regular moisture in the soil, but the roots should not sit in standing water, as this can cause root rot. Providing good drainage is key, as magnolias do not perform well in waterlogged soils.
Planting Guide
Planting a Bay Fig Magnolia involves choosing the right location and ensuring that it has the necessary space to grow. Here are the key steps for successful planting:
- Location: Choose a spot that receives full sun for at least 6 hours a day. The tree requires a spacious area to accommodate its large size, so avoid planting too close to structures, fences, or other trees.
- Soil Preparation: Bay Fig Magnolias prefer well-drained, moist, fertile soils rich in organic matter. Amend the soil with compost or well-rotted manure if necessary to ensure good drainage and fertility.
- Planting Depth: Dig a hole that is twice the width of the root ball and only slightly deeper than the root ball. This ensures that the roots can spread out easily while the top of the root ball is level with the surrounding soil surface.
- Spacing: Space the trees at least 30-40 feet (9-12 meters) apart to allow for the tree’s wide canopy and avoid crowding.
- Mulching: Apply a 2-3 inch layer of mulch around the base of the tree, being careful not to pile it directly against the trunk. This helps retain moisture, suppress weeds, and regulate soil temperature.
Fertilization Schedule and Recommendations
Bay Fig Magnolias benefit from regular fertilization, especially during their early years of growth. The ideal time to fertilize depends on the specific needs of the tree and the climate, but generally, you can follow this schedule:
- Early Spring (March - April): Apply a balanced slow-release fertilizer, such as 10-10-10 NPK, to encourage vigorous growth. This helps the tree to develop healthy foliage and roots as it begins its active growing season.
- Late Spring to Early Summer (May - June): A second round of fertilizing can be done with a liquid fertilizer or an additional dose of slow-release fertilizer. During this time, focus on fertilizers with higher phosphorus (P) to promote blooming and root development.
- Late Summer (August - September): If necessary, apply a balanced fertilizer again, but avoid high-nitrogen fertilizers at this stage, as too much nitrogen can promote excessive leaf growth at the expense of flowers and fruit.
- Fall (October - November): No fertilization is needed in the fall, as the tree is entering its dormancy period. Fertilizing at this time can encourage new growth that may be damaged by the cold.
- Winter (December - February): Avoid fertilizing during the winter months as the tree is not actively growing.
USDA Hardiness Zones
The Bay Fig Magnolia is most suited for USDA hardiness zones 7-10. In these zones, the tree will thrive year-round, with minimal risk of frost damage. In colder climates, the tree may struggle, especially if temperatures drop below 20°F (-6°C) for extended periods.
