Methods For Maintaining A Lupin Plant?

Lupines, also known as bluebonnets, are easy-care, dramatic garden ornamentals that fix nitrogen in the soil. They are planted in spring or fall and require a well-drained soil, with a planting hole at least 2 to 3 feet apart. Seeds should be planted in early spring about a month prior to the last estimated frost. In warmer climates, they may be sown in the fall in an unheated greenhouse.

Planting lupines involves digging a planting hole in well-drained soil, planting and firming in place, watering and providing plant support, and planting in full sun to light shade. Young plants tend to establish better in the garden than larger, more mature ones. Fall planting is preferred for seed and plants, and transplanting is not recommended.

Lupin care is simple once you have the know-how. Support is usually necessary for tall annual lupins and perennial varieties, with canes 4ft (1.2m) long, spaced around the plant. Lupines are diligent food-finders and do not need any special feed. After planting, keep the soil evenly moist to ensure good root development. Encourage air flow around plants to reduce humidity and remove affected growth from the plant.

Lupines grow and bloom best in full sun, with at least six hours of direct sunlight on most days. They can tolerate mild shade, but blooming will be slower. Newly planted lupines should be watered regularly during their first summer, especially during hot, dry spells. They prefer full sun, light shade, and sandy, well-drained soil.
