How To Grow
How To Grow
Sowing: Plant Swiss chard directly in the soil approximately one week after the last spring frost, burying the seeds about 1.27 centimeters deep in compost-enriched soil exposed to full sunlight. Space the plants 10-13 centimeters apart for entire plant harvesting, or 20.3-25.4 centimeters apart for continual outer stalk harvesting, promoting larger growth. To ensure a continuous summer crop, sow additional Rhubarb Red Swiss chard seeds every two weeks. Expect germination within approximately one week. Swiss chard exhibits tolerance to light frosts and can serve as a suitable fall crop.
Growing: Maintain consistently moist and weed-free soil through the application of mulch. Adequate moisture is particularly critical during the seedlings' initial growth stages.
Harvesting
Harvesting
Harvest individual leaves for greens once they attain a height of 15.24-20.32 centimeters. For harvesting the entire plant, cut it at the surface of the soil, leaving approximately 2.54 centimeters of stem intact to facilitate continued growth and subsequent harvests. Alternatively, outer stalks can be harvested individually, leaving the central heart to mature further.
Seed Saving
Seed Saving
Due to Swiss chard's wind-pollination, ensure isolation from other chard and beet varieties by a minimum distance of 3.22 kilometers to maintain genetic purity. To facilitate seed production, chard plants must endure winter conditions; in warmer climates, mulching suffices, while in cooler climates, root storage in sand, with adequate spacing and humidity, is necessary. Replant the roots in early spring. Upon seed head maturation in spring, wait until they are fully dry before removing them. The seeds easily detach from the stems when completely dry. Store Rhubarb Red Swiss chard seeds in a cool, dry environment for up to five years.
