Why have my Hydrangea cuttings turned yellow?

CraighBCraighB Posts: 704
Hi guys,

I took some hydrangea cuttings last Autumn and I potted them on into fresh compost about a month ago. Since doing this they have gone from a lovely dark green to a pale yellow! I have checked the compost and it doesn't seem overly wet and neither is it dry. It isn't compacted as there is some perlite in there and it feels just right.

Could anybody tell me what might have happened?

Thanks
Craigh

    I know nothing about Hydrangeas but starvation is a cause of yellow leaves

    Normally l would agree with starvation, but the fact they've only recently been repotted doesn't seem to indicate that. Overwatering can also cause yellowing, or may be an iron deficiency? .

    Yea I doubt it would be starvation as it was only a month ago they were potted on and it was good quality jack's magic compost mixed with John innes no 2 and perlite. Other plants are doing brilliant with that same mix.

    As cutting go they look fine to me.  I do find they like a bit of peaty compost. Keep them in the shade, but outside for a while. 
    Once they grow on a bit and go in the ground they’ll look perfect.
    I’ve got 60 here all grown from cuttings over the years.

    Yes, didn’t the vine weevil eat them or have you still got some? 
    I can do them to order, enough to choose from here 😱😀

    they suffered with the dreaded vine weevil, but they limped back to life.

    Wow! That was very lucky.  Have they shown you what colours they are yet?

    I thought they looked quite sickly so it's good to hear you think they look ok Lyn!

    Im going to move them today into some shade. It will be interesting to see if they still continue to grow because they seem to have slowed down quite a lot.

    Fingers crossed I will be buying a house this year so im taking cuttings of certain plants that will be difficult to move such as my Hydrangea King George. So I do hope these cuttings do well :)
