☀️ Where to Plant It

Magnolia grandiflora loves:

• Full sun to partial shade (6+ hours of direct sun preferred)
• Well-drained, slightly acidic soil
• Sheltered locations, especially in colder zones

It’s not picky, but it does best where it has room to spread—don’t crowd it too close to other trees or buildings.

🌬️ Tip: In windy areas, plant near a fence or building to protect the branches from snapping.

4. Water deeply and mulch with bark or pine straw
5. Keep the mulch 2–3 inches away from the trunk to prevent rot

💧 Maintenance & Care Tips

Magnolia grandiflora is relatively low maintenance once it’s established, but here are some pointers:

💦 Watering

• Keep soil moist during the first 1–2 years
• Once mature, it’s drought-tolerant
• Deep watering is better than frequent light watering

✂️ Pruning

• Minimal pruning needed
• Remove dead/damaged branches in late winter or early spring
• For shaping, prune right after flowering

🍂 Fertilizing

• Feed with a slow-release, acid-loving plant fertilizer in early spring
• Avoid over-fertilizing—too much nitrogen = fewer flowers

🐛 Pests & Problems

Generally pest-resistant, but keep an eye out for:

• Scale insects – check leaves for sticky residue
• Leaf spot or black sooty mold – often related to pest activity
• Wind damage – younger trees can be fragile

🌱 Good news: Deer usually leave them alone!
