Mansfield garden calendar for SEPTEMBER

Sep 14, 2015 02:07PM ● By Mary Phillips

Despite recent high temperatures, fall has finally arrived in North Texas!  Tried-and-True Texas gardeners know that September is one of the busiest – and most beautiful – months to enjoy our outdoor spaces…


-Vegetables: September rivals April for Texas vegetable planting. As evening temperatures continue to fall, this is the time to sow beets, carrots, cilantro, chard, collards, snap peas, lettuce, kale, mustard, parsley, radish, spinach, and turnips.  Seedlings of broccoli, cabbage and cauliflower can also be set out now.

-Revitalize your flower pots and annual color beds – plant mums, asters, petunias and marigolds for bright splashes of interest that will last until our first freeze. 

-Lawn and Landscape:  Plant heat and drought friendly perennials for garden-bed-boosts this year and beyond: Texas tarragon, ruellia, sedum/stonecrop, ornamental grasses, sages, and echinacea. Looking for interesting, native or more unusual plants for your landscape? Try your local farmers market! 

-Sow wildflower seeds at the boarders of your lawn for a lovely spring show that will delay your first mowing date next spring.  Wildflowers can also be sown in perennial beds – but as they are often quite tall, place them toward the rear for enjoyment into the summer months.


-Prune any dead wood or dying growth from trees, shrubs and perennials.

-Dead-head (cut back spent blooms) from perennials that are finished blooming to encourage healthy leaf and root growth.

General Garden Care:

-Enjoy the fruits of your summer gardening labor – search for new recipes to enjoy squash, tomatoes, beans, peppers and melons.  As summer vegetable plants begin to lose their vigor, clean them from your beds and compost them.

-Do a quick walk through to inspect for insects. Treat any growing or noticeable infestations appropriately.

-Consider the placement of any sculptures or other visual garden features.

-September ushers in the season of sharing – divide and re-plant your spring/summer blooming perennials that are done flowering for the year.  Cut the stems back to about 6-8 inches above the soil line for daylilies, daisies, iris, yarrow and other early bloomers.

-Plan any tree or shrub plantings that you intend to do this fall, and begin researching the best varieties and availability of your choices.

 Happy Gardening – let's make Mansfield even more beautiful!
