    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.

When daffodils don’t bloom

I covered my daffodils in the fall with a heavy layer of pine straw. The leaves have come up but they are not budding or blooming. Is the pine straw too acidic for these plants?

Daffodil copyAfter a long winter, we look forward to the daffodils blooming in spring, and it’s a disappointment when they don’t produce the flowers we expect.

The failure to bloom is not due to pine straw causing acid soil; daffodils – or jonquils, as we sometimes call them — tolerate a range of soil types, as long as it is well-drained and moderately fertile, and some varieties actually prefer slightly acid soil. A lot of garden experts suggest mulching daffodil beds with a light layer of pine straw. Small, early blooming daffodils may not be able to penetrate a thick layer of mulch.

So consider some of the other possible reasons daffodils don’t bloom:

Were they cut down too quickly last spring? After daffodils finish blooming, allow the foliage to remain until it turns yellow. This allows the bulb to gather and store energy for growing and blooming the following spring.

Were they given a high-nitrogen fertilizer? Nitrogen tends to grow a lot of foliage at the expense of flowers. Fertilizer that contains a higher level of phosphorous promotes blooming.

Is the bed too crowded? Bulbs continue to grow and divide underground, and after several years, the bulbs may grow big, lush clumps with few or no blooms. If it’s an old, established bed, it may need to be thinned. Dig the bulbs, separate and replant them.

Too little sun? Daffodils need six to eight hours of sunlight to bloom well. They tolerate dappled shade in early spring, but if they are in dense shade, they likely will not bloom.

These are among the most common causes. The American Daffodil Society has a whole page of reasons that daffodils fail to bloom, which you can read here.

For gardeners in Middle Tennessee (where The Garden Bench calls home), this is a good time to mention that the Middle Tennessee Daffodil Society is holding its annual Daffodil Show March 19 and 20 at Cheekwood Botanical Garden. This is the time to see some of the most perfect daffodils grown and arranged by serious daffodil aficionados. To learn more, visit the MTDS site here.
