Fighting scales on citrus plants, who has good experience in
« on: September 12, 2021, 08:07:09 AM »
I found two citrus plants in my collection with a lot of scales. I sprayed them with oil and hope to get rid of, in former times, with only one lemon I had good results. But now I found still at two other plants in my collection a single scale, which I removed by hand.
Now I ask me if I should spry before overwintering all my citrus (ca. 70 pots)? I will overwinter them by 1 ° C in a greenhouse).
Who have good experiences how to protect, prevent scales.
Thank you Frank

I use horticultural spray (40 grams oil/gallon H20)  Works very well.  Scale in a highly invasive insect, and you need to constantly watch out for them.

Thank you Millet, you are 100% right.
Do you spray preventive, when, before overwintering in autumn? Or do you spray only if you see some scales ?

Mostly only when I  see scale  Mealy bug is another insect that seems to show up every now and then.
