Hi plant lovers, I have a large red striped dracaena and the smallest stem looks somewhat infected with these white marks all over the leaves and the stems. The leaves are dying one after the other but it hasn't spread to the rest of the plant. I have a lot of success with my plants usually but admittedly I know little about looking after them ! Please could someone explain in simple terms what I can do about this and what it even is. Thank You!

Looks like a terrible case of mealy bugs. A good, heavy spray of rubbing alcohol will help. Azamax would be even better. Isolate it from any other plants you have. Gene

I would also re-pot it with new soil and perlite, make sure you wash that pot thoroughly with hot soapy water Welcome! to the forum

The key to treating mealybugs is to spray so thoroughly that all leaf and stem surfaces are literally dripping wet. If you fail to make direct contact with all the virtually invisible juveniles, they will survive, reproduce and come back to haunt you.

I would advise against disturbing the roots and soil. It is highly unlikely that any of the mealybugs are living in the soil. Marginata roots are fragile and easily damaged when disturbed.

The presence of plant pests is often an indication that the plant is stressed and weakened by something else - usually, improper light or watering.
