  • March garden tips & tasks

    If your fescue lawn looks a little skimpy, overseed early this month. Fescue grows best when the weather is still cool.

    Clip dead stems from perennial herbs – thyme, sage, lavender, rosemary. Pruning encourages vigorous new growth.

    Prune nandinas, flowering quince and other airy shrubs by reaching in and removing about a third of the branches at ground level.

    Remove mulch or leaves that may be covering perennials in garden beds.

    Prepare a new garden bed: Have the soil tested (check with your county’s Extension service). Remove grass and dig or till soil 8 to 10 inches deep and mix with soil amendments and organic matter to improve drainage.

    Add fertilizer lightly to perennials as soon as you see new growth. Too much fertilizer may result in lanky growth.

    Herb transplants that don’t mind cool weather -- parsley, cilantro, sage, oregano – can go in the ground now.

    When you cut daffodils to bring inside, cut the stems at an angle and place them in water right away. Change the water in the vase daily to keep them fresh longer.

Plant perennials now, enjoy them later

I’m still seeing perennials for sale at garden centers. Some of them are being sold at reduced prices. Can they really be planted this time of year?

Daylilies are among the perennials that can be planted now.

Spring is the typical planting time, but for gardeners who are willing to be patient or take a chance on a plant that may look like it’s past its prime, early fall is a good time to plant. Many of the plants on sale still have plenty of life, even though they don’t look their best right now.

But if you make careful choices and plant now, they will begin to establish good root systems and should spring back beautifully in the garden next year.

While perennials you find now may not be at the peak of perfection, you should still look for healthy plants with no sign of disease. Here are guidelines from the website of Clemson University’s Cooperative Extension and other sources:

  • Look for plants with good color and vigorous appearance. Avoid plants that show any sign of disease.
  • Ease the plant out of the pot and look at the roots look healthy, and not mushy or limp. Avoid anything with roots that have a bad odor.
  • Buy labeled plants (unless you want to be surprised!) and label it in the garden so that you can remember where and what you planted next spring.
  • In the garden, prepare the soil and amend it as needed with compost. Dig a hole a few inches wider that the plant’s pot, remove the plant from the pot and gently loosen the roots, then set the plant in the ground with the base of the plant level with the surrounding soil. Fill the hole with soil, water thoroughly, and add mulch.
  • Don’t set them out and forget them. October can be a dry month, so remember to provide water on a regular basis.
