I'm in Zone 7, so this may not fit everyone's March to-do-list. Those of you a little further north will want to wait a month or so...
- Remove all the leaves, twigs and fallen branches that have accumulated in the yard over the winter months. Even though I removed all the leaves in the fall, there will still be some in the spring that have blown in over the winter.
- Trim up the foliage on the summer blooming perennials that are above the ground. I normally trim up my evergreen herbs like rosemary, etc. during this time. I also prune most of my roses in March. Keep in mind that it is too late to prune your spring blooming perennials and shrubs (forsythia, quince, etc.) - prune these later after the blooms have gone.
- Dig out all the weeds that have started to spring up in the flower beds. As hard as it is to believe that those suckers can grow in February...they do. Weeding now will reduce your job in this regard later in the year!
- Cut back vines and ivy that has grown out of its territory.
- Cut back ornamental grasses, including liriope, and the dead stems of perennials (I always leave these during the winter for the birds and other wildlife) to a few inches high.
- Loosen the old mulch with a cultivator (or in my case, a gloved hand) acorns and other dried plant matter that has accumulated around my shrubs and perennials. Air needs to be able to better penetrate those roots!
- Reseed and fertilize the lawn.
- Fertilize my spring bulbs.
