Croton leaves going dark
Hi my croton's leaves have all slowly turned really dark purple. It sits right next to a bright window indoors and I always make sure i water it when it needs. I also have a young plant in the bathroom that's also looking like it might be doing it too. Could you pleas advise me on how to get its nice yellow, red and green colour s back? Thanks Ella

This can happen with plants that remain in an area with too much humidity. At this point it may die from the infection. It has progressed further than what will be able to be saved. It is best to make sure the area gets plenty of air circulation, and using peroxide at 1 part peroxide to 3 parts water will help if you use this once per month.
Unfortunately, there may be no saving this, and only prevention in the future.
