No flowers on my Cosmos !!

I have sown Cosmos Purity from seed every year for the past 5 years with spectacular results in my white garden, however this year I have healthy looking green fern foliage with not a hint of a flower .......I also had a problem with the seed germination and contacted the seed suppliers who replaced 2 of the 5 packets I had purchased, I was told to look at their website for hints on germinating seeds !!!!! Has anyone else had this problem ??  Dordogne Sue

    Good morning.  I'm only just starting to get buds on mine, but I was really late planting them out so I think thats probably got a lot to do with its been a bit dull and wet in scotland the last few weeks.  this is the first year I've grown them, so I am no expert, sorry.  Hopefully someone that knows what they are talking about will be along soon image  ps.  If in doubt, I usually give things a liquid feed and wait and see image

    Everything in my garden is weeks behind everyone else's (my nasturtiums still have two leaves) and my Cosmos have been in flower for a couple of weeks now.

    Try a feed as PL says and see how they go but that sounds a bit odd to me. Are they well watered and everything? If you've grown them before you know what you're doing so it may simply be down to a wet/dry/cold/hot spell at the wrong moment. image

    agree with Verdun re feeding. Don't.

    Flowering and seeding is a plant's response to challenges, starvation, drought etc

    lots of leaves is the response to an easy life with plenty to eat and drink

    I've no flowers yet either, not worried as everything's been late this year with the funny weather we've had. image

    Hello Dordogne Sue and welcome to the forum.

    I, too, live in Dordogne. I often have trouble growing Cosmos, I thought it was because the summers are too hot and dry. But it gives me hope that you have had success with Cosmos Purity. This year I tried Antiquity, dismal failure. But I have 3 Sonata in the veg garden, they are healthy, but it should have been 20!

  • Thankyou very much for your responses ...have had plenty of sunshine no different from the last five summers, I too purchased some other seeds Gazebo White from a well known chain store in UK and they are absolutely brilliant ...... I think it could be down to over fertilisation in a powder form in 2 particular beds at the start of May ????

    I have also grown Gazebo this year, alongside Sonata and Rubenza.

    As usual I grow them on in 1L or 2L pots then plant out as and when.

    This year I've had 2 Gazebo that I thought were blind.

    In the pic there's one just above the blue salvia, but there does seem to be some sort of bud developing slowly. They were all sown on the same day and these were all planted out on the same day.
