I am excited seeing my 2 yr. old medinilla has a bud but also i am seeing very small almost like pollen particles on many of the leaves and stems of the budding area. Is this an insect or what and how to treat???? Thank you for suggestion. Denise Daugherty
Pests are not generally an issue with these plants.
Without an image, it's difficult to tell.
If you do have an infestation, Neem Oil is a good treatment.
Try brushing away the particles you mention or place them on a white piece of paper to help get a better look.
