Pacific Northwest

Deadhead roses for continuous bloom. As blooms fade, cut spent flowers just above a five-leaflet leaf, preferably outward-facing. This directs energy into new flowering shoots.

— Genevieve Schmidt, landscape designer

California

Star jasmine: the versatile summer perfume. Grow as a vine, ground cover, or container plant for year-round foliage and sweet summer fragrance. Less demanding than gardenias.

— Bill Marken, garden editor

Southwest

Plant sunflowers for beauty and temporary shade. Easy from seed all summer; they shield heat-sensitive edibles like cucumbers and tomatoes.

— Noelle Johnson, Arizona horticulturist

Rocky Mountains

Water wisely: target the root zone. Hot, dry, windy weather demands efficient irrigation. Adjust systems to deliver water directly to roots, not broadcast.

— Jocelyn Chilvers, Colorado landscape designer

Texas

Water lawns deeply, less often. Encourages deep roots for drought resilience. Add a rain sensor to automatic systems to prevent overwatering.

— Jenny Peterson, Texas landscape designer

Central Plains

Wild quinine (Parthenium integrifolium): unique native bloomer. 3×3′ perennial with long-lasting white "cauliflower" flowers. Dry to medium soil, full sun. Zones 4–8.

— Benjamin Vogt, Nebraska garden consultant

Great Lakes

Container vigilance: water daily (or twice) in heat. Small pots and hanging baskets dry fastest. Don't let them crisp.

— Barbara Pintozzi, Illinois garden coach

Northeast

Interplant flowers with veggies for pollinators. Calendula self-sows, offers edible petals, and draws beneficial insects. 'Flashback' variety shown.

— Charlotte Albers, Vermont landscape consultant

Mid-Atlantic

Deadhead and harvest herbs for fall production. Keep snipping coneflowers, lavender, basil. Remove aggressive weeds like bindweed.

— Amy Renea, garden writer

Southeast

Pinch back leggy summer annuals before vacation. Petunias especially benefit — cutting stem tips encourages branching and bushier growth while you're away.

— Helen Yoest, North Carolina garden writer
