Grand Rapids TBR Seed Tape (2.5m) - 2/pk

Product Details

A seed tape version of this flavourful tipburn resistant (TBR) variety. Grand Rapids TBR Looseleaf lettuce seeds produce a large, upright rosette of thick, juicy, light-green, frilly leaves and a blanched centre. 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.

1 pack includes 2 x 2.5m (6.5') of tape and contains approximately 350 seeds in total.

Start by making shallow rows in prepared soil. Unfold tape and separate the two strips. Place tape in the rows and water. Cover with 5mm (0.25 inch) of soil. Water well. Keep consistent moisture until seeds sprout in 7-15 days.

Matures in 65 days. (Open-pollinated seeds)

How to Grow Looseleaf Lettuce Seed Tape

Step 1


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. 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.

Step 2


Seed tape is designed for the ease of direct sowing. Unfold seed tape and separate into two strips. Place the strips onto the surface of the soil, spacing the seed tape rows 45-90cm (18-36″) apart. Lightly cover with soil, about 5mm (¼”) deep. Thin looseleaf seed tape to 20-25cm (8-10″) apart.

Step 3


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. Regular watering is essential to prevent leaves from developing a bitter taste. 

Step 4


Days to maturity: From direct sowing. Most varieties will be ready for harvesting as baby leaves in half the days shown on the packet.

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.

Step 5


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.


Disease & 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.

Companion Planting

Lettuce plants make good companions for beets, Brassicas, carrot, celery, chervil, cucumbers, dill, garlic, onions, radish, spinach, squash, and strawberries.
