Perennial hit list for March

It’s time for Spring Maintenance to begin.  We have already gone over cutting your perennials back for spring but there are a few other important tasks to consider.  Here is a quick list of what you need to be thinking about concerning your perennials for this month:

  1. Be patient.  It is still a little too early to think about getting many perennials in the ground that have been grown in containers.  Most of these plants will not have had the time to properly take root well yet.  If you are planning on installing any bareroot perennials and it’s not to wet to work you beds you can go ahead and install these.
  2. Remove any leaf mulch of evergreen boughs from your perennials.  It is wise to keep these close at hand though in case it looks like we are going to get a typical late frost.  I would recommend this is done on a cloudy day so that any shoots starting to emerge are not too shocked by the change in light exposure.
  3. Press any perennials that are showing signs of heaving from the frost back into the ground.  Make sure you do this very carefully.
  4. Fertilize your perennial gardens towards the end of the month or into the beginning of April.  Top dressing your beds with compost can also be done at this time.  Make sure that you don’t apply this to thickly; you don’t want to smother any new growth.
  5. Touch-up the mulch in your beds at the end of the month.
  6. Cut back perennials that were left for winter interest (refer to prior post on cutting back perennials).
  7. Cut back your liriope.  If you have a lot of it you can mow it just like turf grass.

I hope this helps answer some questions for all of you.  If you need further advise I would recommed The Well-Tended Perennial Garden by Tracy DiSabato-Aust.  I refer to it constantly when I need to check what all needs to be done when.  This is a must have for your horticulture library.  As always let me know if you have any questions and good luck.
