    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.

Slugs feel at home in the hostas

QUESTION: I have hostas in my yard that were beautiful all summer, but they are now riddled with holes. What could have happened to them?

The broad leaves of hostas lure slugs to the shade, where they also find a tasty meal.

When you find holes in your hostas, the problem most likely is snails and slugs say the experts at U.T. Extension. Hostas are shade plants, and slugs and snails are right at home in a shady, moist environment. The large, wide leaves create a shady spot, so they stay in that cozy spot all day and come out at night, climbing up on the leaves to dine.

If you want to see how active they are, try this: place a small board, about six inches wide, beside the hostas where you’ve noticed damage. In the morning, turn the board over and see how many have collected on the underside (and dispose of them as you wish). A gardening friend told me recently that she had set out an old tuna can filled with beer beside the hostas in her garden. The next morning, the can was full of slugs, and she dumped the whole thing into the trash.

The American Hosta Society suggests several solutions for protecting plants from slug dining damage, one of which is to provide something else to eat that might be just as tasty, such as lettuce. A different strategy focuses on placing a barrier around vulnerable plants. Strips of copper on the ground can be effective because slugs don’t like to cross it. Maybe that’s a way to use all those pennies that collect around the house. Table salt sprinkled around the plants also may keep them away, but you probably don’t want to add all that salt to the soil. My friend who lured slugs into a tuna can also said she has tried sprinkling diatomaceous earth around the hostas as a barrier they won’t cross.

The American Hosta Society mentions a couple of poison baits, but also suggests that a 10% solution of vinegar, sprayed on the slugs, stops them in their tracks – but you have to be out there with the spray when they are out, which is usually at night. And finally, a trap: place two boards together with a small stick between them, where the slugs can crawl in and hide in the cool shade. Then, when the slugs are between the boards, remove the stick and stomp. Ewww.
