    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.

Winterize your roses

I’ve heard gardeners talk about “winterizing” roses. What does that mean? And how do you do that?

Winterize rose shrubs to prevent damage from cold and wind.

If you live in an area that experiences intense cold or cycles of freezing and thawing, you may have heard about the importance of winterizing your roses. While rose shrubs are generally hardy, some varieties may be vulnerable to extended cold weather and strong winter winds. “Winterizing” helps protect roses from winter damage.

The process begins in late summer. You should discontinue fertilizer applications about mid-August, to slow down new growth. Stop cutting off the dead blooms in early October, which signals the plant to stop producing new growth.

Now comes the important “winterizing” part: Between now (late November) and mid-December, cut the canes back to 2 to 3 feet tall to keep them from blowing around in the winter winds, loosening the soil around the roots. Rose experts at the Nashville Rose Society suggests placing a 12-inch high mound of soil or mulch around each bush. To minimize winter damage at the end of each cane, you can also erect a small cage of chicken wire around each bush and pile about two feet of hay or other loose organic material inside.

Miniature roses and others grown in containers can be moved to an unheated garage or other space where the temperature remains above 20 degrees. Plants should be watered just enough to keep them moist.

For advice on roses in Middle Tennessee (where The Garden Bench calls home), I usually turn to the rosarians at the Nashville Rose Society, who provide excellent information on growing roses at their website. We are in USDA Hardiness Zone 7a, and the schedule reflects normal conditions in our climate. Gardeners in colder areas may adjust accordingly.

Rose enthusiasts can also get information (and see photos of beautiful blooms) from Birmingham, Alabama-based rose expert Chris VanCleave aka “The Redneck Rosarian.” He writes about roses, hosts podcasts, and keeps the conversation going with #RoseChat on Twitter.
