It’s time to prune summer blooming plants! The roses, hydrangeas and clematis seem to top the list. I’d like to share a few tips:

  • Prune only in dry weather as many diseases are spread through rose foliage
  • Prune above an outward facing bud for best new growth
  • Thin out weak, contorted, crossing or dead canes
  • Pruning hard is good and actually helps the plant rejuvenate!
  • White flowered hydrangeas bloom on new wood, so prune canes hard to a sturdy framework that will support new growth and lots of flowers
  • White flowered oak leaf hydrangeas bloom on old wood, so preserve as many canes to the tips as possible
  • Blue hydrangeas bloom on either old or new wood, depending on the variety, so see the attached list from Proven Winners, that lists all the newer varieties
  • You’ll always be safe if you cut the old stems to the 36″ height above an outward facing bud
  • Selectively remove old wood, broken stems and excess dried stalks
  • Train clematis to its support early and often, then let it rip!
  • Topdress with compost and scratch in a slow release organic fertilizer as a jump start
