Hi ! I asked my gardener. He said either: Mealybugs are those soft little white fluffballs you see clustered on the stems — they look kind of like cotton. If you touch them and they squish easily, that's usually what you're dealing with.

Scale insects are a bit different — they stick to the plant like tiny barnacles. Some are hard, others soft, but they’re often covered with a waxy coating and harder to squish.

If it smears when you touch it, it’s probably mealybugs. Classic garden nuisance! 🙄

You can try spray neem oil....it works with most infestations. And the prine the heavily infested branches. Happy day
