iceberg seeds

Iceberg lettuce ‘Saladin’ is not susceptible to bolting, but is less suitable for autumn cultivation. It can be grown as baby leaves. This iceberg lettuce forms medium sized heads with thick, crispy leaves.

Iceberg lettuce Saladin forms semi-big to big crops. Its leafs are thick and crispy. Saladin does not bolter early. It is not ideal for autumn cultivation. Growing Iceberg lettuce is slightly harder than growing the other lettuce varieties, but you could also see it as a challenge! Iceberg lettuce is slightly sweeter on average. It has a longer growing period (two weeks) than other types. If you would like to eat lettuce each week, you have to sow/plant regularly. When you put a part of the lettuce close to each other and if you harvest a little earlier than normal, you could suffice with one sowing per three to four weeks.

Days to Maturity: Lettuce can be picked whenever real leaves form. Pick when the leaves are younger rather than waiting so the taste doesn’t become bitter. (See each variety for days to maturity)

Fertilizer: Lettuce is typically a care-free plant, but you can fertilize the soil with an organic fertilizer one week prior to planting the seeds. Lettuce grows best in soil that is high in humus. Fertilize three weeks after transplanting seedlings with an alfalfa meal or a slow-release fertilizer.

Lettuce is a cool-season crop, and seedlings can tolerate a light frost. Lettuce grows quickly, so stagger the plantings. It is recommended to sow the lettuce seeds directly into the garden as soon as the soil can be worked.

Our Seed Promise

Planting: For direct seeding, seeds germinate at low soil temperatures (40°F), but poorly above 75°F. Sow seeds 2-3″ apart, rows 12–18″ apart. Cover seed lightly, about 1/8″, and firm soil gently. Thin iceberg and romaine lettuce to one plant every 10–12″, other types 8–10″ for full size heads or 6″ for mini heads. Dry soil must be watered to ensure coolness and moisture, and for uniform germination. For transplanting, sow 2-3 seeds per cell, 1/4″ deep, 3-4 weeks before transplanting outdoors. Do not let soil above 70F while germinating so keep out of sun and a cool, dark location. Harden seedlings by reducing water and temperature for 2–3 days before planting outdoors. Properly hardened transplants can survive temperatures as low as 20°F. Transplant iceberg and romaine lettuce 10–12″ apart, in rows 18″ apart. Other types 8–10″ apart in rows 12–18″ apart for full size heads or 6″ apart for mini heads.

Before Planting: Lettuce is hardy and can be planted as early as the soil can be worked. It is a cool weather crop and grows best at temperatures of 60-65°F. Careful variety selection is important for hot weather plantings. Sow every 3 weeks for a continuous supply of fresh lettuce. Lettuce seed can enter thermal dormancy when exposed to high temperatures. Do not use a heat mat when germinating lettuce seed. Optimum germination results at soil temperatures of 60–65°F.

Iceberg seeds

Start by sowing the non-GMO seeds 1/2 inch in soil, twelve inches apart, in rows eighteen inches apart. Make sure to allow enough space between seeds for the lettuce to grow, as overcrowding can cause the lettuce to have a bitter taste. Firm the soil lightly. While growing, keep the soil well watered. Harvest 70 to 79 days after planting.

70-79 days. These non-GMO Iceberg seeds grow into green heads of lettuce that are ready to harvest in 70 to 79 days. The Iceberg lettuce is one of the most popular varieties of crisphead lettuce, and can be grown in zones 4-9. The leaves of the Iceberg have a mildly sweet flavor. Approx 16,000 seeds per oz.

Crisphead Iceberg Lettuce (Lactuca sativa), is also known as Crisphead lettuce. Iceberg Lettuce is the one of the most popular types of crisphead lettuce, and has been a favorite for many years. Its popularity is due to its crisp, juicy texture. While not known for its impactful flavor, iceberg lettuce has a subtle, sweet taste. It is used in salads, on sandwiches, and as a garnish. Iceberg lettuce is an annual grown in zones 4-9. They prefer cooler weather, but need sunlight to grow properly. If they heat up too fast, or too early, iceberg lettuce could prematurely bolt, or go to seed. They are best when harvested just before this point, when the inner leaves are firm. Heat can also cause splitting or rotting, so start lettuce in the early spring so it can be harvested before the high heat of summer. Iceberg lettuce has been a staple vegetable for many years, and is a great addition to any garden.
