I have a tree lupin and have pruned it to shape regularly in spring. It has always recovered well and I live in a cold but sheltered part of mid wales where we get hard frost and lots of snow. hope this helps

Hello Kathy,
It sounds like you know something about these. After reading Dave Goulson's book about bumblebees I decided that my rooftop garden had to have one of these. How do you think it will do in a container? I've put it (came in a small 9cm sq. pot) in a 20cm round plastic pot and set it for now in a sunny south-facing location that gets rather a bit of breeze (thinking "coastline" here).
What do you think?

Hi, Charles,
It sounds like your last tree lupin behaved as expected - they are very fast growers but are short-lived. Generally, they require little or no pruning and can be expected to reach 1.5m tall and wide. However, if you want to keep it a bit more compact, you can cut it back by half in early spring. That pruning recommendation is typically given to those who grow it in its native California where winters might be milder than where you live. if you live in a colder area, it might not respond as well to pruning.

I had a tree lupin which grew rapidly and took over the whole flowerbed
I have pulled it up and planted a new one which is very small at the moment
With regard to looking after it I appreciate it should be deadheaded as required but how do i PRUNE IT TO KEEP IT REASONABLY SMALL AND NOT HAVE A REPEAT OF LAST TIME
mANY THANKS
