Surrey, United Kingdom
Hope someone can shed some light on this for me - I had a beautiful anthurium (don't know what type, it was pink and dutch) given to me as a housewarming present 3 years ago. It was flourishing on a south facing windowsill...until about a month ago.
I first noticed that the lower leaves had discoloured and become yellow and blotchy, then other leaves, even new ones,went the same way. I think I have identified the problem as being scale because of the waxy deposits and spots on the leaves (seriously disgusting and made my skin crawl when I saw one move!) and sprayed the whole plant with provado. Having checked again this weekend, there was still quite a lot of scale, so I chopped off all the older lower leaves, leaving just the uninfected ones. There is the odd waxy spot on the leaves, but on the whole, the plant is a lot clearer.
My query therefore is have I done the right thing, should I be doing anything else and should I be worried about the scale spreading to my other houseplants - which thankfully appear to be clear at the moment.
