I think I have made a big BOO BOO

Nanny41.....do you know what the lowest temperature would be in the conservatory during the winter?
Obviously they cant be frosted, but as they loose their leaves could you bubble wrap (with lots of layers) and put in the conservatory?

Hi everyone
I read with interest your comments and suggestions.
I've decided to re-pot in JI ericaceous compost which I already have in the hut.
From what as been said I think the problem was placing the pot in full sun.I have a position with late afternoon sun which is more sheltered which may suit better.
Fingers crossed.

Just to add to the mix jeanie, I had no idea that Ericaceous compost should be used. Mine was potted up about 7 years ago in bog-standard 3-for-a-tenner compost. It sits in full sun and seems to be enjoying life.

Do you see what I mean about being confused!!!

I have taken it out of the sun though, but not re-potted.

I am very wary of high nitrogen plant food and tend to stick to bonemeal.
My plants have grown really well this year.

I am going to have to fight my way into that flower bed to sort them out.

We experienced very windy weather recently which was easily enough to scorch and damage tender leaves. I imagine the miracle grow encouraged soft growth and then the wind did the damage .

Give it a feed of Sequestrene. That should sort it out.

Water it , it needs lots of moisture , I throw my tea leaves round it whenever I remember . I have two red ones and one green

Springy chicken....I agree with you over the new soft growth being susceptible to damage.
I didn’t realise how much moister at the roots keeps the leaves from browning though.
I would think that if both strong sunlight and drying out too much would contribute to crispy brown leaves more than the type of soil the tree is in.

Alina....what a lovely acer. You’ve done well!!
