Full-Sun Deck Flowers: Annuals for Continuous Bloom and Heat Survival

Afternoon/Evening Sun Deck: Annuals That Take the Heat and Keep Blooming

Deck faces highway, gets hot afternoon sun. Not full-day sun, but the intense half. Annuals are your best bet for non-stop color.

Heat-Tolerant Annual All-Stars

• Marigold (African/French) — bulletproof
• Zinnia (Profusion, Zahara series) — disease resistant
• Alyssum — fragrant, self-sows
• Geranium (zonal) — classic, tough
• Petunia (Wave, Supertunia) — spreads, blooms
• Blanket Flower (Gaillardia) — native tough
• Nasturtium — edible, trailing
• Portulaca (moss rose) — succulent, loves heat
• Snapdragon (cool spring/fall, rests summer)

Heat Wave Protocol

• Water DEEPLY every MORNING
• NEVER wet foliage (sun burns water droplets)
• NO fertilizer >90°F
• Light feed every 2 weeks when cool

Annual Soil Refresh

New potting mix EVERY YEAR. Old mix = compacted, salted, diseased.

Morning shade + afternoon sun = "heat half-day." These annuals handle it if watered right.
