How to Grow

Planting Swiss chard should occur in early spring for harvests starting in late spring through early fall in cooler zones (3-7). For overwintering harvests in warmer regions (8-10), sow seeds in the summer. Ensure soil is moist, light, fertile, organically-rich, and well-drained; Beta vulgaris (Leaf Beet Group) ‘Bright Lights’ appreciates cool summer temperatures but tolerates heat well. Seeds are sown in clusters, and once seedlings emerge, thin them carefully by hand, aiming for rows about 18–24 inches apart in vegetable plots.

Watering should be regular and consistent; never allow the soil supporting your Swiss chard to dry out completely. These plants benefit greatly from the addition of nitrogen fertilizers as needed throughout the growing season to support lush leaf development. To maximize tender leaf production, regularly harvest the largest leaves from the outer edges of the clump, even if they are left uneaten; this practice encourages new, tender growth from the center, maintaining the aesthetic appeal of Beta vulgaris (Leaf Beet Group) ‘Bright Lights’.

Landscape Uses

The exceptional coloration featured in Beta vulgaris (Leaf Beet Group) ‘Bright Lights’ makes it highly versatile, moving it beyond standard vegetable patches. Cultivars with multi-colored petioles are excellent choices for ornamental front borders where their upright clumps add height and contrasting texture against lower-growing annuals. They also serve well in cottage gardens or as striking additions to mixed containers, providing edible foliage that doesn’t sacrifice visual interest. When grown in vegetable gardens, the spacing should account for their 1.5-foot spread to allow air circulation while ensuring the vibrant colors are visible.

In the garden, plant them in mass as a vibrant, colorful low hedge bordering a walkway or patio area where the stalks catch the light.

Since harvest encourages better growth, integrate these edible ornamentals directly into formal flower beds rather than isolating them in a dedicated vegetable patch. This allows you to enjoy the structure provided by the chard leaves while harvesting small amounts of young, tender leaves for salads as needed.
