Question: are lupins good for pots?
Answer: When rooted, plant your lupin firmly where it is to flower, be it in a pot (yes, you can grow lupins in pots) or in a garden and water it in. ... 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.
