Campsis - no flowers

RoddersUKRoddersUK Posts: 506

Bought a couple of campsis for some large pots last year, didn't expect to flower as late in the year, but put on some good growth.
This year, it's grown a lot, but no flowers.
Did notice the label said feed through spring, not summer and then again later in the year.
I've been feeding it every week, but stopped now.
It's in a very sunny hot spot.
Can you over \ under water them?
What else can cause them to not flower?

    We inherited one, badly positioned over an old well and with an indication to triffid its way down the drive.   I have thus given it severe haircuts each year and conclude that it flowers on previous year's growth.  others I see on arches and gateways and walls flower madly but don't get the same pruning.

    I expect yours will flower with gay abandon - next year.

    I hope so! But I didn't trim last year, so should have had a few?
    Oh well, foliage still looks nice along the fence.

    When I grew it I noticed that it flowered much better if we’d had a lovely sunny summer the year before to ripen the wood ... so fingers crossed for great blooms next year 🤞

    Ok, I'll give it another year!

    It's worth threatening it a bit.. Bunny on GQT does that with good success.  If it knows you plan to have it out if it doesn’t make a display next year, it still has opportunity to redeem itself by putting the work in now.

    You'd better stand back when it starts to grow properly. I saw one last year that had shinned up a high fence and was eating a bus shelter😯

    @B3. Yes they can certainly make some growth, very vigorous. In Bruges old town there's a court yard full of them and they're almost to the top of the building. Hard to see any soil or Containers there. I bet they don't get pampered and fed. Flowering beautifully though.

    Bought myself one this year for the pergola. I've got it in a large container so we will see how that works out. I do have some flowers but there were already vestigial buds when I bought it. 

    Wondering how old your plant is @RoddersUK, maybe they only start flowering at a certain maturity? Mine was quite big and had some ripe wood on it already. Like Dove said, there's a good chance of flowers  next year  :)

    Mine were only approx 1ft tall when I bought them, so very young I expect. No flowers in them when purchased.

    You may have to wait at least one year if not two.

    Ours was established and grew 40' down the drive while our back was turned selling our old house and moving into this one.  We hacked it all back to the well and it tried again the following year.   We now loop some stems over the well and leave them in place all winter.  It's those which are flowering now, not the shortened ones.

    What are you feeding it with ?  I use tomato or rose food for all my flowering plants as it contains a higher ratio of potash which encourages flowers.  General plant food contain less potash and more nitrogen which stimulates roots and leaves.

    its worth a try.
