"How to Germinate and Grow Lupine (Lupinus) Seeds
Germination Instructions
Preparation:

Lupine seeds have a hard outer shell, so they benefit from pre-treatment to improve germination rates. Scarify the seeds by lightly sanding them with sandpaper or nicking them with a knife. Soak the seeds in warm water for 12-24 hours before planting.
Sowing Seeds:

Choose a seed tray or small pots with good drainage. Fill them with a seed-starting mix, which is light and well-draining.
Sow the scarified and soaked lupine seeds about 1/4 inch deep in the soil. Lightly cover them with the seed-starting mix.
Watering:

Water gently to moisten the soil without washing the seeds away. Use a spray bottle for even distribution. Keep the soil consistently moist but not waterlogged.
Light and Temperature:

Place the seed trays in a location with bright, indirect light. The ideal temperature for germination is between 55-70°F (13-21°C).
Germination Time:

Lupine seeds typically germinate in 14-28 days. Maintain consistent moisture and light conditions.
Growing Instructions
Transplanting:

Once the seedlings have at least two sets of true leaves and are strong enough to handle, transplant them to their final location. Harden off the seedlings by gradually exposing them to outdoor conditions over a week.
Site Selection:

Choose a location with full sun. Lupines prefer well-draining soil that is slightly acidic to neutral. They thrive in sandy or loamy soil. Prepare the planting area by loosening the soil and adding compost if necessary.
Planting:

Plant the seedlings 12-18 inches apart to allow adequate air circulation and growth. Dig a hole large enough for the root ball and plant at the same depth as they were in the seed tray.
Watering:

Water regularly to establish the plants, keeping the soil consistently moist but not waterlogged. Once established, lupines are fairly drought-tolerant and require minimal watering.
Feeding:

Lupines generally do not require much fertilization. Too much fertilizer can lead to excessive foliage growth with fewer blooms. A light application of a balanced fertilizer in the spring can help.
Mulching:

Apply a layer of mulch around the base of the plants to retain moisture, regulate soil temperature, and suppress weeds.
Care and Maintenance:

Deadhead spent flowers to encourage continuous blooming and prevent self-seeding. Trim back the plants after the first flush of blooms to promote a second bloom. Tall varieties may need staking to support the flower spikes.
Pest and Disease Control:

Lupines can be susceptible to aphids, slugs, and snails. Treat pests as necessary with insecticidal soap or neem oil. To prevent diseases, ensure good air circulation around the plants and avoid overhead watering.
Overwintering:

In colder climates, apply a layer of mulch or straw to protect the plants during the winter months. Lupines are perennials and will regrow in the spring."
