Sickly cosmos?

Hi

Anyone know what these cosmos might be suffering from? Just brought them. The compost was very wet .

thanks

 

I think it's down to overwatering . If you let them dry out before watering again, they should improve.

 

They look nothing like Cosmos to me, are there multiple types or are ours not Cosmos (as on the packet)?

 

It's chocolate cosmos, a perennial species.

 

Thank you.
Unfortunately I could not find a nice clear web picture of it (the leaf), but this was near enough....


very nice too!

 

Mmmm perhaps pot bound as well?

 

thank god. they were expensive. yes, that was my first thought. was worried it was a virus. thanks mate

 

they are cosmos--see posts below. There are many different types. you might be thinking of the feathery leaved pink/white etc ones

 

no. i checked.

 

It might be better to get it planted out though if you have a suitable site prepped for it. Even if it isn't pot bound, the soil mix may not be ideal for it, so it could be holding water more than is ideal for it.
Yellowing leaves on any plant isn't necessarily a problem, because once any nutrients are used up, foliage can be discarded by the plant in order to maintain the top growth - and there's quite a bit of that.

Hope it comes away well for you though - they're very nice plants, although not 100% hardy, so it'll depend on your location and conditions etc as to how you grow it.

 

Thankyou. Yes, I need to get them in the ground. I think giving them frost protection might help in winter, but it’s harsh in Yorkshire!

 

I hope it does well for you. I wouldn't be able to overwinter them outside here as it's the wet cold that's even worse for them, so they'd need dug up and lifted, or permanently potted to bring inside, and I doubt they'd be happy long term in a pot. A shame, as they're lovely plants. I had one many, many years ago, but didn't realise they weren't true hardy perennials, and lost it after the first winter.

Maybe a case of trying different methods to see what's best. I don't know if they take from cuttings easily, but that's worth looking into.

 

Thanks. Yes, they do not seem particularly resilient t to our mostly awful climate.esp up here!

 

B&Q have got chocolate Cosmos for sale at the moment - not expensive at all! Mind you some of their plants are pretty long and straggly.
I considered it but they didn't really call to me.
