Disease or normal - photo attached

I bought quite a large Radermachera. It looks healthy apart from its got brown lumps on the stem. Is this scale or is it normal? I've read it could be lenticels, or 'barking'. I have no idea. If its scale should I return this plant, or treat the scale? Will I be able to completely eradicate it? Thanks in advance.


  • Hi @karenco.home and welcome to the forum 😊 
    That doesn’t look like scale to me. I’d keep an eye on it to see if it changes, but not be overly worried about it.
