September Lawn & Garden To-Do List

Apples in back of truck

The fall apple harvest swings into high gear in the month of September

By all these lovely tokens
September days are here,
With summer’s best of weather
And autumn’s best of cheer.

-Helen Hunt Jackson, “September”

September heralds the fall gardening season with cooler temperatures and a first taste of autumn in the air. Zones 1-4 will likely experience a first frost, while warmer zones look forward to relief from the late summer heat and drought. September also marks the autumn equinox, when day and night are the same length, and the waning daylight hints at the winter to come.

Now’s the time to be outside to enjoy the beautiful weather while taking care of some of the following lawn and garden tasks for September.

Annuals and Perennials

  • Divide and/or transplant perennials, making sure to feed the roots with a good source of phosphorus.
  • Don’t disturb asters, chrysanthemums, Russian sage, ornamental grasses, or other plants that are of interest in the fall and winter.
  • September is the month to plant or transplant peonies.
  • Plant annuals such as ornamental cabbage, pansies, violas, and snapdragons.
  • After first frost in zones 7 and below, dig up and store tender bulbs such as caladium, canna, taro, elephant ear, dahlia, and tuberous begonia.

    Check for slug eggs under rocks and around the garden edge? Really? Not my idea of a fun time!

    I just bought a 25 acre farm where about 6 acres are mowable, but the other acres are bushhog material and trees. One of my questions is about shrubs, should I wait to take them out and put in new ones? Also, can I spray some kind of week control or killer after bush hoging to try to help control the weeds, etc. for next year?

    I like your idea of bringing plants inside before the night ends. It is a good way to make them last! Any other suggestions for good plants for getting ready for the Christmas season?

    I have been having trouble with my lawn. All summer the length of the grass I cut each week is down from about 4″ to now about 1″to2″s. Could it be the thatch? Please respond. Thank you, Jerry Bravin
