    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.

Boxwood pruning, and May fairs, sales & tours

If boxwoods need trimming, try to get the job done in late winter or early spring, before new growth begins.

QUESTION: Our boxwoods have a few limbs at the bottom that have lost their leaves and appear dead. Is it safe to trim boxwoods at this time of year?

If the limbs are dead, cut them off. No matter what time of year it is, dead limbs serve no useful purpose. If the rest of the shrub seems healthy, those lower limbs may have died because they haven’t received enough sun, or from mower damage. “But boxwoods are pretty good about repairing themselves,” says Randall Lantz, a horticulturist who has a lot of experience with these popular landscape shrubs.

The ideal time to trim boxwood is late winter or early spring, before new growth begins. It’s not a good idea to trim late in the summer. New growth that may follow the trim will not have a chance to harden before winter, and tender new leaves could be killed. Pruning out dead limbs now shouldn’t be a problem, thought. “They’re very forgiving shrubs,” Lantz says.
