Petunias not flowering

Hi
I'm sorry I'm completely new to gardening so I'm trying! I planted some petunias in a hanging brasket and they've been growing really quick and well but not flowering-is this something I'm doing wrong? I'm watering them everyday.  Thanks

    Are you able to post a picture? ( 5th icon from the right in the row of symbols  above the message box where you type, looks like a stylised mountain landscape). 

    Generally - they need sun , reasonably rich soil , and a potassium rich feed to flower. If they were already in flower when you planted them , have you been deadheading?

    More specific advice probably needs a photo.

    You can water and feed petunias too much.  

    Kindness  is not always the right choice.  Many annuals like to be treated hard - poorish soil and just enough water.  Spare the rod and spoil the child.

    It may be that they have come to the end of their season...

    Wow!  It looks like 100 seedlings.  I would plant 2-3 of the hanging type (Surfinia?) in a basket this size (my wife, 6-8).
    You may have masses of small flowers before first frost.  Good luck.  And happy learning.

    Best to sprinkle a few seeds in a seed tray or small pots. As they grow, pot them on to individual larger pots. Four or five plants would be quite enough for a basket that size. This pot has just six plants in it. Seed them March- April and they will start flowering from May-June.


    You've done the first stage - the hard bit - really well, but too late in the year. You could pot them on and try to over-winter them (like cuttings), if you have somewhere handy over winter.

    They do look very crowded, and the individual plants look quite young. Were the seeds sown directly into the basket, and when? As @bede says, you might get some flowers late in the season, fingers crossed.
    For next time, with such tiny seeds it's better to sow them in a tray or pot and separate them into individual small-ish pots when they're big enough to handle but not so big that they're all tangled up, then plant up your baskets when they're filling the pots. They also need a fairly long growing season so they're usually sown around March under cover - on a windowsill indoors or in a warm greenhouse.

    You’ve sown them far too late in the year for them to flower now .They look lovely and healthy though so why not try to take 4or5 out of the basket and put them in a pot somewhere sunny and you might just get lucky and those few might bloom for you .The ones in the basket are far too crowded .

    Thank you for the photo. I hadn't realised you had a multitude of seedlings in that basket , from your opening post I had assumed you bought 2 or 3 ( more mature ) plants for your basket. Can't add to other advice ( you might get lucky if you give a few more space they might flower eventually this year , esp if winter is late-onset) . Only thing I would say is for next year ( when you sow at the correct time) , while it is absolutely true that many annuals do not need a lot of feeding , a sunny hanging basket with profusely flowering plants will likely need meaningfully more watering and feeding than the same plants in the ground.
