How do I eradicate Scaly Bug from my Lemon Bush which is in the conservatory ??? :'(
If only there was an easy answer to this! I have lost loads and loads of citrus because of scale insect. The only way I know is to painstakingly go over the plant with a matchstick squishing each and ever one. Then do it again in a couple of days, then again in a couple of days and so on and so on! I also tried wiping the plant over with a very weak soft soap solution, but I still lost the plant. Given up on them now. I don't believe there is a chemical or organic spray on the market any more to deal with the problem. :-\
I read somewhere about using meths on a cotton-bud, then wash the plant with warm soapy water
I have this problem with my lime, lemon and orange. But then I also grow Oleanders in the same conservatory and they are renowned for getting scale. In previous years I have washed them down 2-3 times a year which controls it but does not get rid of it. They are getting too big to keep washing so last week I used Provado concentrate which is supposed to be the best systemic control around. Very expensive!! I sprayed the leaves as it said in the instructions but I am sure I heard somewhere that you can water it into the soil which would be less messy. Must Google it! I am waiting and hoping now that it works. They are growing well and are a mass of flowers.
