Swiss chard is a leafy green vegetable prized for its tender, mild-flavored leaves and colorful edible stems. 'Bright Lights' is an ornamental cultivar with stems and veins in vibrant shades of red, yellow, orange, and pink, making it as visually striking in the garden as it is nutritious on the plate. Gardeners grow it for reliable production, cold tolerance, and the ability to harvest continuously over many weeks.

Chard seeds germinate best at soil temperatures between 50–85 °F, with 7–10 days typical for sprouting. Seeds are tolerant of cool soil and can be direct-sown as soon as the ground is workable in spring. No pre-treatment is required, but soaking seeds in water for 24 hours may slightly speed germination. Seeds do not require light to germinate.

Direct sow seeds ¼ to ½ inch deep in well-draining soil enriched with compost. Space seeds 2–3 inches apart and thin seedlings to 6–12 inches apart once they have 2–3 true leaves. Chard is best direct-sown in spring after the last frost (mid-May in zone 7 Maryland) and can also be seeded in mid-summer for a fall crop. In-ground or container planting both work well; ensure soil does not compact. For succession harvests, sow new seeds every 2–3 weeks through mid-August.

Keep soil consistently moist but not waterlogged; mulch to retain moisture and regulate temperature. Fertilize every 3–4 weeks with balanced fertilizer or side-dress with compost. Chard is relatively pest- and disease-free, but watch for leaf miners (remove affected leaves promptly) and slugs (hand-pick or use barriers). Bolting is rarely an issue; chard is very heat-tolerant and will produce all season if regularly harvested.

Begin harvesting outer leaves when plants are 6–8 inches tall (typically 6–8 weeks from sowing), pinching or cutting leaves ½ inch above the soil line. Harvest regularly to encourage new leaf production and prevent bolting. Both leaves and stems are edible and improve in flavor after the first light frost. Store unwashed leaves in plastic bags in the refrigerator for up to 10 days. Chard will continue producing until killed by hard frost in late fall.
