Snapdragons in Zone 9 Heat: They Want Sun, Not Shade

You're in Northern CA (Zone 9, 100°F+ summers). Two snapdragons: one in full sun, one in late afternoon sun. Both struggling. You think they need less sun. Wrong.

Snapdragons Love Sun — Even in Heat

• Native to Mediterranean — bred for full sun.
• Heat isn't the problem; inconsistent water is.
• Full sun plant should outperform part-shade one.

Fix the Culture

1. Water deeply, consistently — never let dry out, never soggy.
2. Mulch 2" to cool roots.
3. Feed lightly: Balanced 12-12-12 or 10-10-10 monthly.
4. Deadhead spent spikes to encourage rebloom.
5. Afternoon shade plant: Move to more sun if possible.

Zone 9 Snapdragon Calendar

• Fall/winter/spring annual — plant Oct–Feb.
• Summer = decline/dormancy. Replace with heat-lovers (zinnias, vinca, salvia).
• They'll rebound in fall if roots survive.

Don't baby them with shade. Give sun, steady water, and they'll perform.
