Spring plants: What can survive Chicago's chilly spell?

March 28, 2013 10:10:05 AM PDT
Which types of plants and flowers should you plant in your yard now? Landscape Architect Susan Jacobson with the Morton Arboretum tells us which plants can make it through this chilly spring.

TIPS

1) Plants to plant right now

  • The start of spring planting in Chicago is weather dependent (early last year and late this year)
  • Once the ground is unfrozen we can start planting trees and shrubs hardy to our area
  • Best to wait until mid-May to plant new perennials and annuals (Mother's Day rule)
  • Show sample shrubs & trees that will be for sale at our Arbor Day plant sale April 26-28

2) How to protect plants and buds from cold this year

  • Plants hardy to our area should be fine,
  • Some marginally hardy plants may not flower if we get really cold temperatures after the buds have started opening
  • Even early bulbs such a crocus and daffodils are fine with the cold temperatures
  • The foliage on the early blooming bulbs can take the cold temperatures
  • Keep any extra protection that you may have placed around marginally hardy plant material a bit longer this year
  • Show daffodils in pots

3) What we should be doing to prep our home gardens
  • Make sure your tools are clean and sharp and ready for use
  • Cut back perennials and grasses that you left up for winter interest
  • Prune shrubs that flower on new growth, Late Panicle Hydrangeas
  • Clean debris out of beds and place any needed soil amendments and new mulch
  • Show a pot of grasses that we can cut back
