Hi. I’m new here so please forgive me if I’ve selected the wrong categories. I have planted about 6 crotons 6 months ago. Now they are looking faded in colour and have brown papery leaves On the lower part of the plant which drop off. I’ve never grown them before- can anyone help with suggestions as to whAt the problem is please. Many thanks in advance Ps I’m trying to upload a photo from my phone but seems it won’t work?
