Description: A Grand Rapids-type lettuce with slightly savoyed, deep green leaves that form loose heads. Sow in spring.
Pack Size: 1/32 oz.
Latin Name: Lactuca sativa
Main Uses: Vegetable
Days to Maturity: 28 days baby, 49 days to full size
Exposure: Full sun
Germination Instructions: Germination: 7 - 14 days in soil 4° C or warmer.
Sowing: Indoors start lettuce transplants 3- 4 weeks before last frost date. Sow 5 - 8 seeds per cell or plug. Harden-off seedlings by reducing water and temperature. For best results, apply Sea Magic™ kelp from first watering. Apply a seedling-starter fertilizer such as Evolve Seedling once the second set of true leaves has appeared, and then alternate between the kelp and seedling starter until transplant.
Sowing Outdoors: Sow outdoors in late May or early June, or once soil has warmed to 4° C and there is no chance of frost. Sow thinly 1/4 and 1" apart.
Planting depth: Cover with a dusting of soil. Lightly press into the planting medium to ensure good soil contact. Water the seeds gently with a fine spray. Keep the soil evenly watered until the seedlings emerge, which should be about 7 - 14 days.
Planting Out: Plant in well-drained fertile soil (garden or container) once seedlings are established and risk of frost has passed. For continuous harvest, sow lettuce every 3 weeks.
Fertilizing (Containers): Add 25% quality compost, such as Sea Soil, to the potting mix. Fertilize weekly with a higher-nitrogen organic plant food such as fish-based fertilizer.
Watering (Containers): Water containers deeply when top inch feels dry to the touch. Monitor every day or two during very hot weather.
Growing in Mixed Planters: Only larger mixed planters.
Fertilizing (Garden): Amend garden soil with quality compost such as Sea Soil. Application of Sea Magic kelp every two weeks will result in healthier and more prolific crops.
Watering (Garden): Water young plants regularly to establish, then water deeply as conditions require.
Companion Planting: Planting lettuce between rows of corn will provide some shelter from the heat and sun.
Notes: Mulch plants in summer to keep the soil cool.
Suitability for Indoors: Not well-suited for indoors. Looseleaf and Romaine style lettuces are better-suited to indoors.
