  • 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.

Gardenia is worth pampering

I received a gardenia plant in a 3-gallon plastic pot and a large, beautiful ceramic pot to plant it in for Mother’s Day. It’s outdoors in an area that receives part sun. Only one bloom has opened, but it’s full of buds and will be covered in white flowers soon, I hope. When should I repot it into the new pot? Are gardenias hardy in Middle Tennessee?

GardeniaIf buds have formed since you received this lovely gift, I’d wait to repot it until after it has finished blooming. Gardenias don’t always settle into a new environment easily, and a typical response to such a move is to stop flowering.

After the flowers fade, get ready to pamper this temperamental beauty. I spent some time gathering information about growing gardenias in our area (Middle Tennessee is in USDA Hardiness Zone 7a), and must report that “finicky” is a word often used to describe this beautiful, fragrant shrub.

Gardenias grow best in the ground in Zones 8 – 10, the lower south. For those of us living up north – that is, north of Birmingham or Atlanta – gardenias are not hardy, so they should be treated as house plants, which means that when the temperature drops below 55 degrees, you will have to bring it indoors or into a greenhouse and baby it through the winter. Take it back outdoors when the temperature is consistently warm next spring.

In the house, gardenia requires a sunny spot that gets about eight hours of indirect sunlight. It also becomes a magnet for mealybugs, mites and whiteflies, so you should remain vigilant, and be prepared to treat for pests before they get out of hand.

In spite of the challenges, it’s still worth growing this lovely shrub. Here’s what it needs to thrive: acid soil (one information source suggests good potting soil with a handful of coffee grounds mixed in), good drainage, full sun or partial shade, regular watering, high humidity, and nighttime temperatures of 50 – 55 degrees in winter and spring if you want flowers. Good luck.
