Limelight Hydrangeas – How Much Fertilizer To Use

Q: I am wondering how much fertilizer to use on my Limelight hydrangeas.

A: Don’t apply much fertilizer to a ‘Limelight’ hydrangea. My preference would be to apply a slow-release organic fertilizer, like Holly-Tone or Milorganite, instead of 10-10-10. The later product will likely cause a growth spurt that will lead to floppy branches in summer.
