No flowers on my agapanthus

I bought two agapanthus plants and so far neither has flowered. Is this normal? Any advice for next year?

If you bought them as small plants, say 9cm, they might take a year or even two to really flower well. They just need time to clump up.

Both came in 9cm pots although one is now a good size. Do they need any protection for next year?

They they can be slow to flower so they might not flower in their first year.
From now until the end of September fertilise them every week eg with Tomorite.
If they’re in a pot it needs to be quite a snug fit but not, contrary to what some say, absolutely rammed in.
Use a mix of John Innes #3 and about 25% grit as your potting medium. Normal multi purpose compost will loose its oomph after a couple of months.
Bring the pots under cover in winter such as an open porch or an unheated greenhouse. This is especially beneficial if the agapanthus are the evergreen type with broader leaves. Water sparingly over winter.
If growing them in open ground put them in the sunniest spot. A south facing bed backed by a brick wall is perfect.
Try not to grow them in soil that is too rich. That encourages leaves rather than flowers.
Stake them in good time before 50 mph winds arrive he said, forlornly looking out of the window.

Hi there, I bought my agapanthus 3yrs ago had no flowers so this year I decided to move it to give it full sun & since moving I have had 3 large beautiful blue flowers cant believe it after all these years.

hi and welcome to the Forum. 
It's very important to keep them well watered at this time of year and to feed them as this encourages the new buds to form underground for next year.
