Two years ago I planted some giant delphinium in a boarder together with
gladiolas and lillies with the view that I should get a good mix of
colour from May through to September. This worked well the first year
and everything grew well albeit a bit thin.
Last year the delphinium grew very well with plenty of stalks however
there was no sign of the gladiolas or lillies which only managed to to
grow a few sparce leaves each.
My initial reaction was that the delphinium were starving the over
plants of light / food. Given how well the delphinium grew last year I
am a bit apprehesive to move them, has anybody any ideas as to how I can
encourage the lillies and gladiolas or alternatively suggest something
that will grow well with the delphinium?
Any suggestions are greatly appreciated.
