Question From: Beaubassin East, New Brunswick, Canada
Q: Our weigela bush has tiny white spots on branches and stems. It doesn't appear to be an insect but whatever it is the plant does not look healthy.
A: If the spots are fuzzy, your shrub probably has mealy bug. Take a cutting to your independent garden center for an accurate ID and control. Photos will also be helpful. You might also contact the Canadian OSU Extension Agency for control advice http://oces.okstate.edu/canadian/horticulture. Best And Happy Yardening, Nancy
