    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.

Summer is hard on the lawn

QUESTION: Our lawn has looked great all summer – until now! The grass is turning brown in patches, even though I water it regularly. What’s wrong?

Grass brown patchFor lawn-lovers, the middle of summer often brings disappointment to those who carefully cultivate that carpet of green. I’ve written about the problem here before, but here at mid-summer, it bears repeating.

In Middle Tennessee (Zone 7A, where The Garden Bench calls home), fescue seems to be the preferred type of lawn. It’s a cool-season grass, and it has a tendency to go dormant and turn brown when the weather is hot and dry. It often perks up again when the weather gets cooler.

But lawns can also suffer from brown patch, a fungal disease that can affect fescue lawns. It starts with small brown patches, or a ring of brown grass that gets larger over time. The plant may be green at soil level, but individual blades of grass will be brown.

Before you resort to a fungicide, it’s a good idea to know exactly what the problem might be. I’m not a lawn expert, so when I wrote about this before, I pointed to the popular garden guru and author Walter Reeves’s web site, which provides quite a bit of information about lawn fungus, blights and molds. Here it is again.

In general, lawns do well with about an inch of water a week. They don’t need to be watered every day, but water deeply about once a week if it doesn’t rain. It’s also a good idea to cut the grass higher; when grass is cut too short, it leaves the lawn vulnerable to more weeds and diseases.
