I think some geraniums are later than others anyway and it depends on situations too. I think cold soil is biggest factor. Warm soil and plants grow earlier
not meaning to brag but all my geraniums are large now...rozanne already flowering atop of bjg mounds As is Russel Pritchard and others.
are your geraniums outside? Are they in pots? Hardy geraniums will not enjoy being in a greenhouse now and prefer open ground to pots.
some geraniums prefer shade and some sunshine. Research whether your plants are in places they should be.
a tickling in of fertiliser may help but not too much.......less flowers and more foliage will result
maybe a little patience Tingly
