First time this year from seed. Zinnias are looking ok hardening off but my tithonias look dreadful. Yellowing withered leaves. The pots are no more sodden than the zinnias, both outside but close to the house wall.
are tithonias notoriously difficult to bring on given the poor weather? I’ve put them back in a cold frame to shelter and dry them out a bit. Guess it’s just too wet, cold and windy but would have expected zinnias to be the same.

    In a word yes. Tithonias are also called Mexican sunflowers, which gives you some idea the conditions they like. Better luck next time. Zinnias are from S California, so a bit easier as far dull, cold and wet conditions are concerned, but not much!
    Everyone likes butterflies. Nobody likes caterpillars.

    Lucky you.  None of my Tithonia seeds germinated.  I'll have to try a second batch.

    Yes, too cold, Tithonias do need warmth and cosseting more than most. I started hardening mine off a week or so ago, but only put them out on sunny, warm days. They stayed inside the house when it was cold and wet. Too long inside meant they got a bit leggy, so they aren’t as healthy or sturdy than in previous years, but I think they’ll pull through:

    First time growing them from seed too this year. Monty grows them and they do look great. Mine are now in the garden as they were growing so well. Beginners luck maybe!!  Let’s hope they stay as healthy.

    A quick update. They’ve actually recovered really well once in the ground and in larger pots. Pretty cool leaf shape, Looking forward to some flowers.
