Cultivate fresh, crisp salads with West Coast Seeds - Grand Rapids TBR Lettuce. This looseleaf variety produces a large, upright rosette of thick, juicy, light-green frilly leaves with a blanched center. Grand Rapids TBR is known for its tipburn resistance (TBR) and rapid growth, especially in cool, damp, low-light conditions. Perfect for spring and fall, this variety thrives in cold frames or beneath cloche greenhouses, extending your salad production into winter. Sow short rows often in spring and summer for a continuous harvest and avoid being overwhelmed by mature lettuce all at once.
Key Features:
- Tipburn Resistant: Excellent for cool, damp conditions.
- Fast Growth: Rapid growth in spring and fall.
- Looseleaf Variety: Thick, frilly leaves with a blanched center.
- Extended Harvest: Ideal for cold frames or cloche greenhouses.
- Matures in 65 Days: Quick maturity for continuous harvesting.
Growing Information:
- Season & Zone: Cool season, full sun to partial shade.
- Timing: Best grown in cool weather in spring and fall, but can be grown in summer and all winter in milder regions. Sow short rows every 2-3 weeks after the last frost date for a continual harvest. Use cloches, cold frames, or greenhouses over mid-late summer plantings to extend the harvest into winter. Optimal soil temperature for germination is 10-22°C (50-72°F). Seeds sprout in 7-15 days.
Planting Instructions:
- Starting: Direct sow or start indoors and transplant. Sow seeds 5mm (¼”) deep, or on the soil surface where it can be kept evenly moist. Space heading lettuce 30cm (12") apart, and looseleaf varieties 20-25cm (8-10") apart. Space rows 45-90cm (18-36") apart. For babyleaf lettuce, plant densely for easier harvesting.
Growing Tips:
- Ideal pH: 6.0-6.5. Ensure soil has ample drainage and lots of organic matter. Add compost and lime at least 3 weeks before planting. Use one cup of balanced organic fertilizer per 3m (10') of row for adequate nutrition. Harden off seedlings by reducing water and putting them outdoors 2-3 days before transplanting to prevent transplant shock and premature bolting. Regular watering is essential to prevent bitterness.
Harvesting Tips:
- Leaves or Heads: Pick individual leaves or harvest full heads. Mature summer lettuce stays in prime condition for a short time, so harvest promptly and keep planting. In fall and winter, plants stay in good condition longer.
Companion Planting:
- Good Companions: Beets, Brassicas, carrots, celery, chervil, cucumbers, dill, garlic, onions, radish, spinach, squash, and strawberries.
Diseases & Pests:
- Prevention: Crop rotation is essential. Tipburn, caused by calcium deficiency, can be managed by ensuring proper nutrient balance and consistent moisture. Slugs can be problematic in early and late plantings; clean up hiding places and water in the morning to control them.
