It is necessary to soak lupine seeds in water for 24 hours before planting the seeds to soften the seed's exterior. The seed can also be refrigerated for seven days to prepare for planting. Lupines should be sown directly into the garden after the last frost, or indoors in a moderately warm growing medium 15 days before the last frost is expected. Spring is the best time to propagate lupines from cuttings. To grow lupines from cuttings, place the cutting in sterile soil in a well-heated, humid environment, such as a terrarium or greenhouse, until the plant is rooted.

Planet Natural recommends loosening soil up to 20 inches deep to allow for the lupine's long root systems and using fertilizer monthly until the flowers on the plant begin to bloom. After the first flowers appear, water lupines regularly and maintain moisture in dry regions by applying a natural mulch, such as cedar mulch, around the base of the plant. After lupines have bloomed, BBC recommends removing the flowering spikes in order to stimulate growth. To deadhead lupines, cut the flowering spikes off with a sharp knife or scissors near the closest bud or directly under the flower spike.
