Grand Rapids TBR Looseleaf lettuce seeds produce a large, upright rosette of thick, juicy, light-green, frilly leaves and a blanched centre. This tipburn resistant (TBR) variety has good flavour. The variety features very rapid growth in spring and fall, and grows better than any other variety under cool, damp, low-light conditions. Try Grand Rapids TBR in cold frames or beneath a cloche greenhouse for salad production all winter. In the spring and summer, sow short rows often so the crop can be harvested over a long period, and so that you are not overwhelmed by a garden full of mature lettuce all at once.

| Starting |
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. |
| Growing |
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. |
