Heirloom Swiss Chard Seed
(Beta vulgaris var. cicla)
Heirloom / Open Pollinated Swiss Chard is hardy and prolific, tolerating poor soil and inattention, it can withstand frost and mild freezes. Direct sow Swiss Chard seeds in spring 1-2 weeks after soil can be worked. They can be planted from April to mid-July. Soaking seeds for 15 min in warm water prior to planting will speed germination. Plant seeds in full sun (can tolerate part shade) ½” deep, 1-2″ apart, in rows 18-24″ apart. Should germinate in 5-17 days in soil 50-75°F. When plants reach 3″, thin to 4-10″ apart. Water regularly for best growth and to prevent bolting (going to seed prematurely) and bitterness. Can be harvested continuously. When Swiss Chard plants reach about 6″ can begin harvesting the outer leaves, leaving the inner leaves to continue growth. You can also cut off the whole plant 2″ above the ground and it will grow new leaves.
