Pomegranate Crunch Pelleted Organic romaine lettuce seeds are CERTIFIED ORGANIC! This petite lettuce is like a cross between a romaine and a butterhead, with small, dense heads with cherry red leaves and light green hearts with a splash of red. The leaf ribs are very clean and uniform. The colour transition from the outer leaves to the heart is very smooth, creating a beautiful contrast. The heads of this variety have very uniform size and shape. Seeds are pelleted and sold by seed count. Be sure to keep the seed bed constantly moist until germination. Pelleted seeds require constant moisture.
Matures in 45 days. (Open-pollinated seeds)
Size: 50 seeds
How To Grow: Lettuce can be harvested from the garden from late spring to the late fall, and sometimes (given a bit of protection) all winter. The high protein chlorophyll in the dark-green leaves is highly nutritious. Salads are not complete without these leafy greens. Read more below on how to grow lettuce from seed.
Season & Zone
Season: Cool season
Exposure: Full sun to partial shade
Lettuce grows best in cool weather in the spring and fall, but it can be grown in the summer, and all winter long in milder regions. Sow short rows every 2-3 weeks following the last average frost date for a continual harvest. Using a cloche, cold frame, or greenhouse over mid-late summer plantings can extend the harvest period right into winter. Optimal soil temperature for germination: 10-22°C (50-72°F). Seeds should sprout in 7-15 days, depending on conditions. Lettuce seeds don’t sprout easily when the soil temperature is over 22°C (72°F) in summer. Get around this by sprouting them indoors in a cool area, or pre-sprout by sprinkling seeds on a damp paper towel and placing it in a plastic bag in the fridge for a few days. In hot weather most lettuce goes to seed rapidly, so have new plantings ready to go, and watch for "good resistance to bolting" in the product description.
Direct sow or start indoors and transplant. Sow seeds 5mm (¼”) deep, or on the surface of the soil where the soil can be kept evenly moist.. Space or thin heading lettuce to 30cm (12″) apart. Space or thin looseleaf varieties to 20-25cm (8-10″) apart. Space rows for all types 45-90cm (18-36″) apart. Babyleaf lettuce can be planted quite densely, as it is harvested at an immature size. Sowing babyleaf lettuce seeds closely together in narrow rows makes harvesting simpler.
Days to Maturity: From direct sowing. Most varieties will be ready for harvesting as baby leaves in half the days shown on the packet.
Ideal pH: 6.0-6.5. Aim for a soil with ample drainage and lots of organic matter. Add compost and lime at least 3 weeks prior to planting. One cup of balanced organic fertilizer per 3m (10′) of row will give adequate nutrition. Seedlings should be hardened off by reducing water and putting the plants outdoors 2 or 3 days before transplanting. This will help to prevent transplant shock and premature bolting. Regular watering is essential to prevent leaves from developing a bitter taste.
Pick individual leaves or wait and harvest full heads. Mature summer lettuce stays in prime eating condition only a short time, so harvest promptly and keep planting. In fall and winter the plants stay in good harvest condition longer.
In optimal growing conditions at least 70% of seeds will germinate. Usual seed life: 3 years. Per 100′ row: 240 seeds head lettuce/1.2M seeds leaf type, per acre: 58M seeds head lettuce/348M leaf type.
Diseases & Pests
Crop rotation is important for disease prevention. Tip burn (tips of leaves turning brown) is caused by a calcium deficiency. If you have limed, tip burn can be caused by nutrient imbalances or lack of moisture. Slugs are a problem in early and late plantings, so clean up their hiding places, and only water in the morning.
Lettuce plants make good companions for beets, Brassicas, carrot, celery, chervil, cucumbers, dill, garlic, onions, radish, spinach, squash, and strawberries.
