March: Annuals and Perennials

Cool-weather annuals and most perennials take the stage.

The first 60-degree day in March inspires us to plant any and everything. However, it is important to invest your time and money only in cool-weather annuals that can survive March's fickle temperatures. Pansies, primrose, and ranunculus enjoy the cool spring weather and should go in once nighttime temperatures remain above 30 degrees.

Early spring is a great time to plant perennials. During the cool weather, watering needs are not as great and the plants have time to become more established before heat sets in.

Now is a great time to prepare new flower and vegetable beds by adding soil amendments like Sweet Earth or Soil Builder to the existing soil.

Early spring is a great time to do some garden clean-up in the annual and perennial beds. Dead annual plants must be removed, as must the dead foliage of perennials. Apply slow-release food like Agriform or Osmocote to perennials to get them off to a good start.

Plant tender annual and vegetable seeds indoors now to transplant outside once the threat of frost has past, usually no earlier than the third week of April.
