Why are my lupins drooping?
Herein, why are my Lupin leaves drooping?
Well-Drained Spoil Although lupines tolerate poor, dry and sandy soil, they suffer if the soil is wet. Soil that is too heavy, too wet or has too high a pH causes iron chlorosis, signaled by a yellowing of the lupine leaves, and root rot caused by fungi of the Rhizoctonia and Fusarium genera.
Also Know, do lupines die back? Lupine stalks can be cut back in mid August, or any time after the seed pods have opened (or you have gathered them). The leaves will be building root reserves for next year's flowering until they die back in November. They will bloom starting in June of their second year.
Beside this, what's killing my 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. Anthracnose first became a problem on ornamental lupins in the 1980's, and is now the most damaging disease affecting them.
How do you take care of lupins after they bloom?
Lupins prefer well-drained soil which isn't too rich. Lupins do not take too kindly to being chopped back hard after flowering - they take months to recover. If you have a good plant, don't let it produce lots of seeds. Keep the vigour in the parent plant and deadhead as the flowers fade.
