What Causes White Marks on Plant Leaves
Hi Judy, i have attached 3 pics in the hopes you might be able to tell me the problem. Thanks in advance.
From the picture it looks like your croton is getting burned by being in the direct sun. The plant likes very bright light, but not any direct sun. If you think that this could not be the cause, please let me know and I’ll suggest some other possible reasons. You can read all my care tips for a croton in the Popular Houseplant section of the website.
