    Tips & tasks – September

    Cut the dead tops of coneflowers, but leave enough for goldfinches to enjoy the seeds.

    Plant cool-weather vegetables for a fall crop: spinach, mustard and turnip greens, radishes, leaf lettuce.

    Start a new lawn of cool-season grass, such as fescue, or refurbish or repair establish lawns.

    Don’t let the soil of newly planted grass dry out. New grass needs about an inch of water per week.

    It’s still warm, so continue to water and weed garden beds as needed.

    Remove dead foliage, spent flowers and other garden debris; replenish mulch as needed.

    Continue to harvest produce, which may be getting a boost now from slightly cooler weather. Keep watering sage, rosemary and other perennial herbs so they’ll be in good shape to get through winter.

    Prepare to bring houseplants back indoors: remove dead leaves, scrub soil from the sides of the pots, treat for insects. Bring tropical plants in before nighttime temperatures dip to 55 degrees.

Keep Rosemary happy

I have a small  rosemary bush that is thriving, and hope it lives through the winter. What is the best way to care for it so it survives?

Rosemary cuttings can root in water.

More and more, I was hearing gardeners say their rosemary, which does not always make it through winter outdoors in this area, was getting through the cold just fine. Then last year, many gardeners I talked to said their rosemary – which may have been growing for years in the same spot – died. Mine did, too.

Herb experts say that the survival of rosemary can be hit-or-miss. It depends on the kind of winter we have, the kind of rosemary that’s growing in your garden, and even where it’s planted.

If we experience a series of very cold days with very low wind-chill temperatures, rosemary may not stand a chance. If the plant is in the ground on the south side of the house, where it’s protected from a cold north wind, it has a better chance of survival. If it’s near a concrete driveway, brick walkway or a stone wall – anything that reflects a little of the sun’s warmth – there’s an even better chance it’ll make it through unscathed.

It’s best chance is if it happens to be one of the hardier varieties that’s planted on the south side of the house and protected from the wind. The Herb Society of Nashville lists the varieties ‘Arp,’ ‘Hill Hardy’ and ‘Salem’ among the best choices for this area. The National Arboretum adds a few more to the list; check out their choices here.

You may be tempted to dig up the rosemary and bring it indoors for winter, but that’s a bad idea. Rosemary is a shrub and won’t take kindly to the dry air and heat inside the house (which is why so many of those cute rosemary topiaries that people give as gifts die so quickly). If you want to try to bring some of your rosemary inside, you may try to snip a few cuttings and keep them inside in a vase of water, where they may grow roots. Change the water every day or two.
