Winter Density Seeds

I am pleased with my purchase of winter density seeds. I am looking forward to planting them and using them in salads. Winter Density lettuce sounds delicious.

Great Addition to Romaine Lettuce Family

I was really pleased with the way it grows and tastes. I have been picking leaves for a few weeks now and this lettuce fills in the gap for texture that Leaf Lettuce does not have. Good flavor.

One of the best.

Very thick rustic and tasty. Grows well in all conditions. Cold weather to the heat of the summer.
I have grown this lettuce for many years. Very consistent and reliable.

Fantastic lettuce

This Fall/Winter 2020/2021 was the first time I tried this particular lettuce. It is a medium size romaine with deep green leaves. I live in the deep South where we generally have fairly mild winters; however, we had some extreme cold this year as well as periods of heavy rain and wind. This lettuce stood up to it all, including the extreme cold (14 degrees). Had given some to my brother-in-law and he said this was undoubtedly one of the sturdiest, yet best tasting lettuces we have grown. Needless to say, this has gone on our "favorites" list and I am buying more seeds.

Days to maturity are calculated from date of direct seeding.

• Lettuce performs best in cool weather, 60-70°F, and grows in a wide range of soil types
• Plant as early as soil can be worked
• For extended harvest, plant every 2-3 weeks and choose heat-tolerant varieties for summer
• Lettuce seed can be sown every month from February—October
• A cold frame and cold-hardy varieties can stretch the spring and fall growing season into the winter months
• Apply 1 cup of TSC's Complete fertilizer per 10 row feet, and 1 inch of compost
• 1 gram of seed will sow 30 row feet
• Consistent, even watering is critical for best results

Direct Sowing
• Use row cover to improve germination and prevent soil crusting
• As soon as 2-3 true leaves have formed, thin loose-leaf types to 10-14 inches apart; icebergs, butterheads, and romaines to 12-16 inches apart

• Start indoors 4-6 weeks before anticipated transplant date

Insects & Diseases
• Common pests: Aphids and slugs
• Pest control: Strong spray of water for aphids or applications of Pyrethrin or Neem oil, baits, traps, or Cabbage Collars for slugs

Harvest & Storage
• While picking individual leaves helps extend the season somewhat, all eventually become bitter as they begin to bolt

What is pelleted seed?
Seed that has been coated with a clay-based material to form a larger, round shape. This makes planting by hand or mechanical seeder easier and allows for more controlled sowing of small seeds such as carrots or lettuce. All pelleted seed has a National Organic Program (NOP) approved coating.
For best results, store pelleted seed in an air-tight container and use within one season.

What is seed tape?
Seed tapes are perfectly straight rows of precisely spaced crops. No more having to thin seedlings! This biodegradable tape will plant a row 5 meters (16 feet, 5 inches) long. Simply lay it in a furrow and cover with a light layer of sifted compost or soil, water and wait. Save yourself a heap of planting time with these popular vegetable and herb staples.
