Maybe you could transplant it into the ground with a good feed of ericacious plant food and a good mulch and lots of rain water if you have it ! This might be just what it needs. I put chicken poo all round mine too !

Soak it in a bucket full of water overnight, then lift out and allow to drain down. Cut back the main stems if they're dead, repot into an appropriate sized pot to accommodate the rootball, using fresh compost, wait and see if any growth occurs. Otherwise, it sounds like an ex Camellia.

Grandmage pelleted chicken poo is very alkaline not what a poorly Camellia needs.

Moon grower is all chicken poo alkaline or just the stuff from the shops? I thought they limed it to get rid of the nasties. It does sound a bit ex unfortunately, but if you have any spare space its always worth a go!

If you look at my photos you will see my Camellia just love chicken poo, This camellia is poorly because they do not like being grown in pots really. They need to spread their roots. Anyway try any of the above, they can be replaced. Marks & Spencer sell beautiful ones.

Alkaline doesn't mean nasty, Sussexsarah - and lime is also alkaline. As substances go, chicken poo is indeed alkaline, meaning not great for acid loving plants, though the amounts used on open ground don't cause too much of a problem usually.
And Grandmage, I suspect this Camellia is poorly because it hasn't been watered...

Yes Bamboo, the plant has been allowed to dry out, they do much better in the garden also chick poo is organic and full of nutrients, nitrogen & phosphorus, just a sprinkling also seaweed is great.

Grandmage yes chicken poo is organic so are various other excrements. But, it is alkaline... Camellias do not like alkaline soil... so to encourage someone who has a poorly Camellia to feed with a fertiliser that is alkaline is not good advice in my opinion.
We once grew a Camellia in a pot for many years - were just very careful to water and feed, though I agree they do better in the ground.
Guest plant your poorly Camellia in the ground if possible in an neutral or acidic soil/compost (digging a big hole and adding the compost if needs be) in a semi shady spot that does not get the early morning sun.
Otherwise follow Bamboo's advice for growing in a pot.
Sussexsarah there are lots of plants/shrubs that appreciate a dose of chicken poo - just not ones that like an acidic soil!

Hello Guest, (I am a little fed up with being shot down on here) do look at my photos and you will see my garden is full of camellias I love them and they are really beautiful, because I give them ericacious plant food and ericacious mulch plus a sprinkling of chicken poo, I am not encouraging you to use the wrong thing merely advising you that is what I do !! I am sure you can make your own mind up with all this advise you are getting! lots of rain water is the secret if you have any and hooray it rained a little today. Good luck.

Well I'm glad you told us exactly what you do, Grandmage - a bit of chicken poo won't do any harm at all if you're also feeding them ericaceous plant food and ericacious mulch, and yes, your Camellias are lovely. But of course, we did not know that you were also doing the ericaceous stuff when you mentioned the chicken poo, so we have to call as we see it.

If you had read all these comments on here and mine was the very FIRST one you will see that I said exactly the right thing, we have been here before & I wouldn't dream of being quite so unkind.
