Growth on potted acer plant
Hello, please see attached photographs. I've only just noticed these little suckers on the bark of an acer. Should I be worried? Is there anything I can do to remove them without harming the plant?
Those are scale insects. You can gently scrub them off using a small stiff brush such as a nail brush etc. Some warm, slightly soapy water will help as they have waxy coatings which protect them from water and bug sprays.
A trowel in the hand is worth a thousand lost under a bush.
If that doesn't work, you can use alcohol. They're not particular.
In London. Keen but lazy.
Thanks Bob and B3. When it comes to alcohol neither am I, lol
