Understanding Igloo Lettuce
Igloo lettuce, also known as “Butterhead” or “Boston” lettuce, is a loose-leaf lettuce variety, meaning its leaves grow in a rosette shape rather than forming a head. It is prized for its delicate, buttery texture and slightly sweet flavor. The compact, upright growth habit of Igloo lettuce makes it ideal for container gardening or small spaces, as it takes up less room than other lettuce varieties.
Choosing the Right Location
Igloo lettuce thrives in cool temperatures and prefers partial shade. A sunny spot in the morning and shade in the afternoon is ideal. If you live in a hot climate, consider planting your Igloo lettuce in a shaded area or use shade cloth to protect it from intense sunlight.
Preparing Your Soil
Igloo lettuce needs well-drained, fertile soil with a pH between 6.0 and 7.0. Before planting, amend your soil with compost or aged manure to improve its fertility and drainage. You can also add a layer of mulch to help retain moisture and suppress weeds.
Starting from Seeds
Starting Igloo lettuce from seed is a rewarding experience and gives you greater control over the entire growing process.
- Timing: Sow seeds indoors 6-8 weeks before the last frost. Direct sow seeds outdoors after the last frost when soil temperatures are consistently above 40°F.
- Seed Depth: Sow seeds ¼ inch deep in seed starting trays filled with seed starting mix.
- Spacing: Space seeds 1 inch apart.
- Watering: Keep the soil consistently moist but not soggy.
- Thinning: Once seedlings have 2-3 true leaves, thin them to 6 inches apart.
Transplating Your Seedlings
When your Igloo lettuce seedlings have developed 4-6 true leaves, they are ready to be transplanted outdoors.
- Hardening Off: Gradually acclimate your seedlings to outdoor conditions by placing them in a protected spot for a few hours each day for a week before transplanting.
- Planting Depth: Plant your seedlings at the same depth they were growing in the seed tray.
- Spacing: Space your seedlings 12-18 inches apart.
- Watering: Water your seedlings thoroughly after transplanting.
Caring for Your Igloo Lettuce
With proper care, your Igloo lettuce will thrive and produce abundant, flavorful leaves.
- Watering: Keep the soil consistently moist, especially during dry periods. Avoid overwatering, as this can lead to root rot.
- Fertilizing: Fertilize your Igloo lettuce every 2-4 weeks with a balanced organic fertilizer.
- Weeding: Regularly remove weeds, as they compete with your lettuce for water and nutrients.
- Pest Control: Monitor your plants for pests like aphids, slugs, and snails. Use organic methods like insecticidal soap or diatomaceous earth to control pests.
Harvesting Your Igloo Lettuce
Igloo lettuce is ready to harvest when the leaves are fully grown and have reached a desirable size. You can harvest individual leaves or the entire plant.
- Harvesting Leaves: Pick outer leaves, leaving the inner leaves to continue growing.
- Harvesting the Whole Plant: Cut the entire plant at the base, leaving the root system in the ground. This will encourage new growth from the base.
Storing Your Igloo Lettuce
To preserve the freshness of your Igloo lettuce, store it properly.
- Refrigerator: Wrap harvested leaves in a damp paper towel and store them in a plastic bag in the refrigerator. They should last for up to a week.
- Freezing: Blanch leaves in boiling water for 30 seconds, then plunge them into ice water to stop the cooking process. Dry the leaves thoroughly and store them in freezer-safe bags. Frozen lettuce can be used in soups, stews, or smoothies.
