Container Wisteria struggling :(

9 years ago

This is a now 6-year old air-layered Wisteria which I got last year in the current pot, with a view to creating a bonsai from it. The owner had suggested it not get repotted for 2 years so in the meantime I've been feeding it monthly with a standard liquid feed this year but unlike last year it hasn't performed quite as well this time. Last year it grew like crazy most of the summer and to my knowledge all the leaves were green at the outset. This year the lower growth started in April then stopped for the best part of May and only restarting after its June feed but now the leaves are purple. Oddly a younger one (2-3 year old cutting) in a much smaller pot seems to be heading the same way so I'm presuming it's a feeding issue but unsure what it's lacking? As Wisteria need a LOT of water I'm wondering if the soil has maybe become depeleted, but gather if you're replacing minerals you need to do it slowly & precisely so I just want to see what everyone thinks.


Anyone able to venture a guess?

    Looks fine to me too. That colouring is normal for new growth as G.G says. 2nd question this week about the phenomenon.

    Hmm - just different for the year but good to know as I'm desperately keen to ensure it makes it through to next Spring when it'll get the chop LOL! Many thanks.

    i would feed it once a year.. and you are wondering if monthly full bore feedings are making it hungry ... personally i think it is severely overfed ...


    what is the media???

    LOL - someday I'll get this feeding lark right. When I started with bonsai my expert who I took my shrubs to for chopping had pointed out at that time how underfed my plants all were so when most went to bonsai size & required monthly feeds I just did the lot - because of my situation they don't get repotted now as I'm downsizing them all where possible, I haven't had any concerns with the few others left but because this one is continually daily being heavily watered I'm more concerned about washing out whatever nutrients might still be in last year's soil. I've no idea what soil it's in as it came already potted & I've not changed it or done any top dressing.

    But now I know it's ok I'll cut back on the feed for a while & see how it goes. Thanks

    there is a bonsai forum.. you might get further in that forum ... with your bonsai dreams i mean ...


    in my mind.. very simply put ..... you can achieve a dwarfing growth rate ... bonsia... by repeated removal of a vast majority of its roots ... and if you keep removing the roots.. you darn well better be in charge of proper feeding.. eh???


    but whats the point of that.. with this plant.. since you are not bonsai'ing it right now ... but you are sort of complaining.. that its growing wildly ... well.. yeah ... your feeding the beegeebees out of it ...


    why havent you begun the bonsai???

    My bonsai expert along with the guy who sold it to me both suggested giving it an extra year in the pot presumably to bulk out the trunk a bit more & I've enjoyed having it grow well (wouldn't say excessively) I'm not complaining in the least about it growing wildly - I only wanted to ensure it wasn't lacking nutrients as I'd not encountered purple leaves on it prior. I would love to have the means to let it grow a lot more but as I can;t manage repotting easily downsizing them to bonsai seemed at least a better option - so far we've done 10 with anothe 8 or so in various stages and as Ian's commended me on the feeding regimen for them, I'm not overly sure I've overdone this one :). All the feed supplements I've bought both for bonsai & container have all said to feed either fortnightly or monthly so that's what I've done. :)

    Whatever you do, NO MORE LIQUID FERTILIZER! Apply no more until you repot, and then use SLOW RELEASE FERTILIZER PELLETS mixed into the soil.

    Just a quick update on this baby - it's been BONSAIIIIDDDD :) Will have a whole new set of issues most likely to deal with, but for now very happy with how it's progressed this year since the repot. I'd feared it was going to grow as it did when in the large pot, but thankfully having (presumably) had its roots chopped, it's just grown a nice manageable amount. We've an aphid epidemic here in the UK at present I gather & certainly I'm having to spray more than usual. My younger (& now wilder) container Wisteria hasn't been hit as hard as this one maybe because the growth is less dense. But otherwise it's doing well despite the heatwave currently. I'm waiting on a box being made to protect the pot as I've few places in my yard it could sit safely as it is currently - the plants already been knocked twice & I don't want to risk any accidents. Will provide a further update later in the year or next year for anyone interested :)
