  • 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.

Callas’ beauty can be fleeting

QUESTION: My calla lilies, which are supposed to be white, are blooming, but the blooms are green! Otherwise, the plants look healthy. In fact, I’ve noticed in the past that they form seed pods. Is something wrong with them?

Calla lilyCalla lilies are lovely flowers, and easy to grow in containers or in the ground. The most common varieties produce white, yellow or pink flowers. That flower is technically the spathe, which wraps around the spadix, where the actual flowers grow. When the spathe turns green, it’s going through its natural life cycle on the way to making seeds.

Susan Bryant at Lakeside Callas in Dandridge, Tenn., explained that the spathe turns darker as it matures, and the outside of the spathe begins to turn green and to close up, with seeds forming inside.

“It starts turning green and closing up after a few days,” she said. Heat and lack of moisture might cause it to close up sooner. If you don’t watch them every day, it’s possible to miss the blooms.

You can cut the flower stalk off after it blooms, which will help the bulb grow larger. The foliage stays green and adds texture and interest to perennial beds. If you allow the seed pods to remain, let the seeds ripen and plant them in a pot indoors to grow over the winter, then put the new bulbs in the garden next summer.  It will take two years for the new plants to bloom, Bryant said. The offpspring may be a different color from the parent.

Callas prefer moist, well-drained soil and grow well in full sun, but they tolerate a bit of shade. In colder climates, the bulbs may need to be dug up and stored over the winter and replanted in spring. Gardeners in Middle Tennessee generally find that bulbs survive the winter in the ground.

  1. If i may ask what can i use for the insects not to eat the leaves:( ?

    • Aphids often chew on the leaves of many types of tender young plants. If you find aphids or other insects, try spraying them off with a blast of water from the hose.
