    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.

Prune clematis for a better show of blooms

Question: Our spring-blooming clematis vine has grown tall and seems very healthy, but it blooms mainly at the top. The bottom six feet has very few blooms and not much foliage this spring. Can you tell me why?

clematis 2Clematis flowers clambering over a sturdy trellis or other support are a lovely sight each spring. When this woody flowering vine gets too top-heavy, with all the flowers at the top and bare stems at the bottom, the problem has to do with pruning – or lack of it. Early-flowering clematis blooms in spring from buds formed last season. Plant experts recommend pruning it each year to help the plant produce the maximum number of flowers. The time to do that is as soon as you can after it finishes blooming to allow time for new growth to produce flower buds for next year.

Horticulturists writing for a fact sheet from Ohio StateUniversity say that sometimes you can cut back into older wood of old, neglected plants to encourage new buds to break. The vines are most likely tangled, so when you prune, make cuts carefully, and train the stems to cover the maximum are on their support.

Note also that there are other varieties of clematis that bloom a bit later, on new growth, and those varieties should be pruned in the winter.

In general, here is what clematis needs to thrive: Loose, fast-draining soil that is high in organic matter, and regular water. Gardeners like to say that clematis prefers to have its head in the sun and its feet in the shade, so provide a thick layer of mulch to keep the roots cool. You can also plant a ground cover such as mondo grass around the base of the clematis vine.
