Mealy bugs have a special gift of making your plant look unloved. Often covered in white fluff, mealy bugs are white and excrete a sticky liquid called honeydew which can cause a sooty mold to grow on the leaves. Your plant will look like it's lost its pep, is sticky, or is covered in white fluff.
While scale is a less common pest, if you are a lifelong plant-keeper it’s bound to crop up at some point. But worry not - with a little bit of know-how and effort you can get your plant scale-less and healthy again in no time!
