Garden tips

  • Do not mulch your peonies, but cut and remove all old leaves and stems
  • Cut back butterfly bush to about 18”
  • Cut back roses now to waist, the later in winter to knee
  • Do not cut back lilac, wait until it blooms next spring
  • Fertilize in-ground bulbs
  • Fall Bloomers
  • Toad Lily (trycyrtis hirta)
  • Japanese anemone
  • Dahlias-tuberose

NOTES:
Wait until either after the first frost OR the middle of November to cut back dahlias.
The greenery needs to feed the tubers, which must harden off after the stems die back.
DO mulch heavily over dahlias after that: Gena mulches, places black plastic over that, more mulch over the top AND a 5 gallon bucket on top!

DO NOT MULCH over peonies after you cut back the frosted stems! They need to sit high and dry and need to freeze to produce!
