Help! Is this mould in the soil of my miniature roses? It has a fluffy dry texture. I’ve done some looking online but I can only find information on mould on rose stems and leaves but nothing about mould in the actual soil? They are miniature roses (indoor). I water roughly every 5 days but I need to increase as I’ve noticed the soil is drying out very quickly. Any suggestions on how to save or do they need to go? I have a beautiful bloom on one of them so I will be sad if I can’t save her :-(
