Hey, does anyone know what pest/condition is causing these spots?
I've noticed this brown spots on my raphidophoras a while ago and I checked for pests, but couldn't find any.
So I treated it and all the surrounding plants with neem oil every three days for a couple of weeks, still new brown spots appeared.
So then I used a chemical pesticide to get rid of whatever could be harming my plants, it didn't improve either.
Two weeks ago I bought Lacewing larvae because I heard they help with a lot of pests. I don't know yet if it worked, but I am afraid it won't help.
Does any of you have an idea which pest or disease causes these spots? I've noticed them on some other plants, but not this extremely.
To any of you who have an idea I'd be extremely happy!
Thank you a lot in advance
