White Spots on Tulip Tree: Lichens or Scale—Harmless or Treatable

White spots on branches are likely lichens (harmless) or possibly scale insects. Snip a small twig with spots and take to a local garden center for ID.

Notes

• Lichens don’t harm tree health.
• If scale, appropriate insecticide can be prescribed.
• One leaf shows sooty mold—check for honeydew-producing insects.

Tree appears to be a saucer magnolia, not a tulip tree (common name confusion).
