Starting Cannes Light Bronze II-III: indoors or direct sow?
🌾 Sow directly in the garden — Cannes Light Bronze II-III is not usually started indoors.
Direct sow seeds outdoors in the garden once all danger of frost has passed and soil temperatures have warmed up for this warm-season annual.
Soil, care & harvest
Prepare loose, well-draining soil with a slightly acidic to neutral pH around 6.0 to 7.5. Since this is a warm-season crop, start seeds indoors 2 to 3 weeks after your last frost date. Sow seeds at a depth of about 1/4 inch in seed trays or pots. Germination typically occurs within 7 to 14 days under consistent warmth and moisture.
Space plants 8 to 12 inches apart to ensure good air circulation and healthy growth. These flowers do not require trellising as they grow upright on their own. Water regularly at the base to keep soil evenly moist but not soggy. Apply a balanced liquid fertilizer every few weeks during active bloom, and add mulch around the base to retain moisture.
Watch for aphids and fungal issues like powdery mildew; prevent these by ensuring good airflow and watering at the soil level rather than overhead. Snip spent flowers regularly to encourage continuous blooming. While not harvested for food, enjoy the showy blooms from late spring through early fall, roughly 105 to 115 days after sowing.
