Portuguese kale (Tronchuda Beira) is a truly special heirloom green, loved by chefs for its exceptional tenderness, heat tolerance, and versatility in the kitchen. Unlike traditional kale, this unique brassica produces thick, flatter, sage-green leaves with bold white ribs that resemble collards, yet have a soft, almost spinach-like texture when cooked and are tender enough to enjoy fresh in salads. Growing up to 24 inches tall, the plant continuously produces new leaves from the center as outer leaves are harvested, giving you a steady and abundant supply. With a rich history tracing back to the ancient Celts of the Iberian Peninsula, it remains a staple in Portuguese cuisine and is famously used in Caldo Verde, the national dish of Portugal—so cherished it holds protected cultural status. For best results, grow in full sun to partial shade in rich, well-draining soil, and harvest often to encourage new growth; it thrives in warm conditions but is not frost tolerant.
Ideal Growing Conditions
Sun: Does best getting 6 hours of sun a day. Grow in partial shade in hot climates.
Water: Keep the soil consistently moist.
Fertilizer: Crops grown to eat their leaves benefit from extra nitrogen. Work blood meal into the planting hole or soil before direct sowing the seeds. Apply more fertilizer every 4 weeks.
When & How To Sow Seeds: For a spring crop: direct sow seeds after all danger of frost has passed or start indoors, in 4 inch pots, 6-8 weeks before your last spring frost date. For a fall crop: direct sow seeds 3-4 months before your first winter frost date. Or sow seeds indoors, in 4 inch pots, 5 months before your first winter frost date (because they need 6-8 weeks to grow to transplant size). When direct sowing seeds - sprinkle a few seeds over the soil surface, pat down, cover with 1/4 inch of soil, and water in.
Germination: 3-10 days
Days To Maturity: 80 days after direct sowing the seed
How & When To Harvest: Can start harvesting smaller baby greens when the leaves are 6 inches long or allow the leaves to mature and harvest when needed.
Common Diseases: The most common diseases are fungal like powdery mildew and downy mildew. Space 1 kale plant every 1FT, do not overhead water, and prune out old, diseased, or decaying leaves to improve air flow. Spray with 1 cup of hydrogen peroxide per gallon of water every 3 to 5 days until you notice the spread has stopped.
Common Pests: The most common pest when growing kale is aphids. Use a strong spray of water to dislodge aphids from the leaves. For more severe infestations, spray with organic insecticidal soap or spinosad. The same caterpillars/worms that like to chew brassicas will also chew kale leaves. Spray with BT or spinosad to treat chewing insects.
