They can be grown in pots, but form much larger and healthier plants if planted directly in the soil.Lupin flowers die from the base upwards on the spires so when the bottom half starts to wilt or even start to turn brown, that’s the time to remove the spire to stop the plant putting its energy into making seed. Cut the stem of that particular bloom all the way down and cut off as far down as you can.
