I have 3 Datura /Brugmanisa a white, pink and yellow all in pots in the garden which are now in there third year.
They are put into a shed to overwinter and then watered and top dressed and cut back for summer in the spring.
The white and pink flower well but the yellow has never had a flower,
anyone any ideas. Thanks in advance
No expert but maybe you are feeding they too well so they just put on greenery ? I'd trying stressing them a bit, but I'm sure an educated opinion will be along soon.
