Secrets To Success When Dividing Perennials

Healthy Strong Plants
  • Select healthy plants
  • Large plants are easiest to divide
  • Allows for plenty of root area for growth
Work When The Soil Is Not Saturated
  • Overly wet soils can clump around roots
  • makes it hard for them to breathe or send out new shoots
  • Can’t take in nutrients

Dig Out The Entire Root Ball

  • dig outside of the root zone by a few inches
  • be careful not to damage roots
  • don’t leaves portions behind

This weeks question comes from Dale from Kansas. Dale asks “I never know how much to divide off of my perennials when I am splitting them. What is the best way to know how much is enough?”

Split Plants From The Bottom

  • the key to success is getting good root portions
  • by turning the plants over, you can see the root structure and not just the foliage
  • Use a sharp knife or shovel
  • Hori – Hori works great for this!

Transplant Immediately

  • Don’t wait for days to transplant, instead, plant right away!
  • the faster you divide and plant, the more time the roots have to develop before winter

Planting Holes

  • Dig holes to twice the circumference of the transplant and 1.5 times the depth
  • Amend the planting holes with compost
  • water the plants in well at the time of transplant

Don’t Fertilize

  • fertilizing can not only cause late season growth, but make plants vulnerable to winter
  • don’t fertilize any perennials after mid summer

Mulch Plants

  • mulch as soon as you plant to conserve moisture
  • helps to lessen transplant shock, in addition, helps against cool fall nights

Protect Plants For Winter

  • Add more mulch to cover plants once they frost back
  • helps protect from excessive freezing and thaws
  • Not just brutally cold winters, but constant thawing and freezing
