  • 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.

Longer life for poinsettias

Question: How long do poinsettias last? The plant I brought home early in December still looks nice, and I hate to throw it out. Will it keep growing?

poinsettiaThe length of a poinsettia’s life generally depends on how much care you’re willing to give it. Some people bring it home to display for a few days, and without any attention at all it dries out and begins to drop its leaves within a couple of weeks.

If yours is still doing well, you’ve given it at least the minimum amount of TLC: indirect light in a room that’s not too warm, enough water to keep the soil moist but not soggy. If you continue to care for it, the plant should last well beyond the holidays. To keep it looking its best, make sure the poinsettia is in a place that’s away from cold drafts or heating vents.

Poinsettia is a tropical plant, native to Mexico. If you manage to keep it until spring, you can let it grow outdoors, though it won’t have its Christmas-hued leaves. (What we poinsettia-flowersthink of as the flowers are technically bracts, or modified leaves. The tiny yellow flowers are clustered in the centers of the bracts.) As spring approaches, cut the plant back to about eight inches tall and fertilize with an all-purpose plant food, and after the danger of frost is past, re-pot the poinsettia outdoors, or plant it in the ground where it will grow into an interesting green plant that will last in the garden until frost kills it.

Some ambitious gardeners are able to “re-bloom” a poinsettia plant, but it takes patience and impeccable timing to provide the right conditions of light and dark needed to produce the colorful bracts.

If you’re looking for more information, the University of Illinois provides its Poinsettia Pages, an info-filled site with all you need to know about this holiday tradition.
