Yellowing leaves on young sapling.

    Pawlonia tormentosa is deciduous so might just be getting ready for autumn.


    Ah, thank you, this is one of the things I queried in post 1. (obviously forgetting the species) I was really curious if it's normal for a tree this young to do that, as it hasn't even started turning woody yet?
    Yes … saplings of deciduous trees drop their leaves just across the more mature trees do. Yiu will he left with just a green stem until next spring. Be careful not to overwater as there will be little transpiration with no leaves on the plant.

    Yes - but providing a link where information is already there saves us repeating ourselves endlessly, week in week out. It also means we can add links to very useful stockists of certain plants.
    I lose count of the number of times I have to say the same things about watering Hydrangeas, Acers or Rhododendrons, tomatoes or Clematis, or how to look after a newly sown lawn, or how to take cuttings, or umpteen other responses. If we didn't post useful links now and again, we'd never do anything else but repeat stuff ad nauseum and drive ourslevges nuts.  :)

    PS - the leaves covered in insects [in one of the photos] and in the surrounding air- they're probably compost flies. 
    Ah, right. Not insects, dirt from the recent repotting, haha, though it certainly does look like insects, I'll admit.

    The leaves are hairy so it's hard to get the little bits off without brushing too hard.

    I’m still wondering what the flea spray was for,  did you spray the cat and missed or something?

    That's why I suggested compost flies @Lyn, as there was a statement about pests being sprayed, and since plants don't get fleas....
    I think I'm missing something here  :)

    - Flea spray.... For fleas. I specifically mentioned carpet and furniture, and it was mentioned for disclosure as a potential cause of my tree's discolouration to give some people (you guys) with more plant knowledge than me all the potential information they needed to make an informed response.

    There was a very good reason I specified flea spray. But didn't think the backstory was pertinent, and also specified carpet and furniture, but here goes.

    When I went to visit my mother earlier in the week I must've picked up a hitch-hiker and brought it home, and while I only saw one, fleas are b****rds and where there's one there's often more. So I bought flea spay (And a flea collar for my mum's cat) to stop a potential outbreak.

    @Fairygirl … I see that Sunflower’s post has been edited, removing the context for my post and yours.  I’m not offended … I accept some folk are less experienced in using the internet and it makes them wary. 

    I would add that saying that posters could ‘just Google’ isn’t really helpful … you have to know what you’re googling for … in this case the OP appeared not to know what his tree was or that it was deciduous … googling without  that information  would’ve come up with all sorts of misleading guff.
     
    Hey ho … think you and I have been here long enough to know roughly what we’re doing …. but as you say, when sitting here typing out long detailed paragraphs of description and advice on my mobile phone, the possibility of linking to reputable sites with appropriate and already published information makes sense to me. It’s one of the huge advantages of the internet. 😊

    Ah - I've just seen your post @Dovefromabove. I'll just repeat the great Peter Green and say 'Oh well'.... :D

    @Automaton539 - I missed your comments re the fleas. Unless it reached the foliage of your plants, it's unlikely to have caused any problem. I think the conditions are just a bit unsuitable, and I'd also agree - it could be time of year. If it's getting a fair bit of sun, that can certainly be a bit too much for a young plant - especially with fleshy foliage  :)

    Oh well indeed @Fairygirl 😊 

    @Automaton539 … I’m wondering if the compost might be a little too water retentive … it looks very fibrous … perhaps it’s readier for something with some gritty loam in it now?

    @Automaton539 It’s normal for the lower leaves to go yellow and die off like that. No need to snip them off, just leave them to die off naturally. Once they’re all shrivelled up they’ll drop off, or you can gently pull them away. If the upper leaves start to yellow or show discolouration, then you have a problem. 

    Maybe you know this already but be careful not to site your plants near the radiators when it’s time to turn them on. 

    I agree that a grittier soil would be good to pot them into. 

    As you’re a bonsai lover, I might suggest also starting some seeds of the more traditional bonsai species, to enjoy alongside your paulownia in case the leaf size becomes an issue.

    I do make sure they aren't always in the sun, it's window ledge when the sun isn't too bright, table when it's sunny outside, as they just straight cook in the window when it's blazing.

    I suppose it's possible, it's a general purpose compost from Wilko. I do only water them every few days though and check not just the top layer when I water, but further down too. Over-watering by only checking the top layer is what killed one of my first attempts I made in the post you mentioned that I made previously.

    While I didn't "know" about the radiators I did assume they'd be problematic for the little guys as was intending to keep them away when they come on.

    And while I do have seeds for some of the more common species, I picked this one to start with due to how easy it was to grow and figured once I'm a bit better with plants I'll try something that needs a bit more actual looking after. :D
