Magnolias are living fossils — their ancestors bloomed before bees evolved. Saucer magnolia's pink spring goblets, star magnolia's white stars, and southern magnolia's evergreen grandeur cover nearly every zone.
Sun: Full sun to part shade. Water: Moderate. Zones: 4–10 (varies by species). Height: 15–80 ft. Bloom time: Spring or summer.
Plant in rich, well-drained soil protected from hot afternoon sun. Mulch heavily to keep roots cool. Prune minimally — magnolias heal slowly. Plant in spring after last frost to protect fragile new growth.
คำถามที่พบบ่อย
01 Why do my magnolia flowers turn brown?
Late frost damage — a classic problem with early-blooming saucer magnolias. Plant on the north or east side of the house to delay blooming past typical frost dates, or choose later-flowering varieties.
02 How big will my magnolia get?
Highly species-dependent. Star magnolia stays 15–20 feet. Saucer magnolia reaches 25–30 feet. Southern magnolia can hit 60–80 feet over decades. Check the cultivar before planting — 'Little Gem' is a compact Southern magnolia for small yards at 20 feet.
03 When should I plant a magnolia?
Early spring after the ground thaws — magnolia roots are fleshy and brittle, so they benefit from a full growing season to establish. Avoid fall planting in zones 5–6 where winter damage to young roots is a risk.
