I have a Dwarf Jade (Portulacaria afra) and would like some help with the signs of root mealybugs. I see white stuff on some bits of soil and fertilizer pellets and every time I water, many bugs that are grayish-white come crawling out. I am nearly positive this is a root mealybug infestation. Also, I have noticed many leaves falling off for no apparent reason. Are there any other signs of root mealies? Also, can you please include some Dwarf Jade-safe options to treat this. Thank you.
