Deadhead lupins once flowers have faded and you should be rewarded with a second flush of flowers. In autumn, cut lupins right back to the ground after collecting seed. Lupins are not long-lived plants – expect to replace plants after about six years.
How do you care for lupines after they bloom?
Cut the entire Lupine plant by half its size after the first flush of flowers is finished in early summer. This will allow the plant to regrow completely and produce a new round of blooms later in the summer. Cut back all the foliage as it turns brown in the fall.
Do lupins need to be cut back?
No real pruning is necessary, although deadheading will prolong the display, and you may wish to trim back faded foliage: With tree lupins, you can cut off seedheads to stop self-seeding.
How do you keep lupins healthy?
Lupins grow best in a spot with full sun or partial shade. Position them in a space with moist but well-drained soil – they also prefer a slightly acidic or neutral soil. Due to their height, growing to around 90cm tall, they do best in a sheltered position where they won’t be damaged by strong winds.

How do you keep lupins blooming all summer?
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. New, smaller flowers will soon appear extending the flowering season.
Do lupines spread?
Lupines are deep rooted and do not spread except through re-seeding. Seeds will not come true to the original variety planted, but will eventually revert to blue-violet and white.
What is the best feed for lupins?
A high potash feed of tomato feed or Vitax will give good flower colour if in pots. Do not use farmyard manure, even well rotted, as it will rot the crowns. Lupins do not need feeding once in the ground as they have nitrogen fixing nodules on their roots which capture all the nitrogen they require from the air.

MICRLUPIN flakes can be fed on their own or mixed with other grains such as MICRBARLEY, MICRMAIZE and or oats to meet dietary requirements or used as a top up to premixed, pelleted or extruded feeds and should be fed with a minimum of 1.5% of body weight as fibre such as quality pasture/ hay and or chaff.
Why are my lupins not doing well?
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.
Why do my lupines keep dying?
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. Root rot inhibits seed germination and causes a general decline of the plant.
How do you prepare lupines for winter?
Potted Lupines should survive winter as long as they continue to have good drainage. The roots are closer to the cold weather in a pot and appreciate being insulated with burlap or garden fleeces wrapped around the outside. If possible, move Lupine pots to a sheltered location, out of the path of storms and wind.
Do lupins multiply?
Lupines reproduce in the wild from seed germination and from rhizomes, or shoots emerging from underground stems. Wild lupine seeds may germinate the same season they appear, or they can remain dormant for at least three years.
Should you deadhead lupines?
Pruning Lupine
Typically a care-free plant, Lupine will benefit from occasional pruning during bloom time. Deadheading spent flowers will encourage another round of blooming towards fall. Deadheading the plant before seed sets in will keep the seeds from dropping into the garden.

Can you dig up and replant lupins?
completely the wrong time of year to do it, but if you must move them give them a good soak and after a while move them with a good rootball, if you can. Water them in well in their new home, and erect some shade for them if it is sunny.
Do lupines only bloom once a year?
Lupine flowers may be annual and last only for a season, or perennial, returning for a few years in the same spot in which they were planted. The lupine plant grows from a long taproot and does not like to be moved.
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.
Where is the best place to plant lupine?
Lupines prefer moist, sandy, well-drained soil and cool temperatures. They can succeed on heavier soils, but you really need to loosen the soil for their long taproots. Select a spot in full sun or light shade. Loosen the soil to a depth of about 1 to 1-1/2 foot.
