QuestionHow do Lupine's do when started in late winter and transplated to outdoor flower beds in spring?
AnswerLupines are in a class by themselves, vividly colored Nitrogen-building perennials.
Lupine roots have a gift for fixing Nitrogen in soil. That gift makes these roots very complex. It means that Lupines do not transplant well... except as seedlings.
When you do put them in the ground, then, remember that. You don't want to have to move these again.
And if you must, then don't do it when they're in flower. It compounds the aggravation for the plant tenfold.
Let me know if you need any more Lupine advice. Thanks for writing!
