How do you take care of a Lupine plant?

Pretty much any climate will be tolerated by lupins. They are very hardy herbaceous perennials, withstanding frost to at least -25C. In very wet conditions, lupins may succumb to crown rot but if well established, will survive most conditions.

Why are lupins so hard to grow?
Lupins do not grow well in clay or chalky soil – they much prefer soil that is neutral to slightly acidic. Moist, well-drained soil is recommended as the optimum, but they will tolerate most garden conditions. Water-logged soil, however, is unsuitable and will most likely lead to rot.
To get the longest flowering period from your lupins, cut off the flower heads when they have died down. The flowers will die from the base of the flower head upwards, the time to dead head them is when two thirds of the flower has died.

What can go wrong with lupins?
Lupin anthracnose is a fungal disease of the leaves and stems. It is spread from plant to plant by rain-splashed spores, and is therefore particularly damaging in wet weather. Affected plants are not usually killed, but can become very unsightly as a result of severe leaf-spotting and dieback.
Overwatering Lupine will not only result in excess foliage production but will also eventually lead to root rot and death of the plant.
Why do lupins droop?
Lupins are drought-tolerant perennials. In most areas, they don’t need any extra water, which is why lupine care is a breeze. If you notice leaves or blooms wilting, they might need a drink. Keep in mind, though, that heat might also be to blame for this response.
