Geranium is not flowering

[dina]

Hi,
I have bought 6 pots with Geraniums 3 months ago but only 2 have flowers now. The others grew tall, no flowers ever and have some leaves which are drying out on the edges. All plants are alive and growing new leaves as well.
What is wrong with my Geraniums? Any advice greatly appriciated!
Thank you.

Did you add too much nitrogen when you planted them? Dig in some bonemeal around the base, maybe the roots aren't spreading and you need a good root system to help the plant grow.

I didnt put anything and Gerraniums are acctually tall although with only 5, 6 leaves but no flowers.
