Janet Laminack: Sow wildflowers, split up perennials


September can be a busy month in the landscape.

We are just past the prime time for using pre-emergents for cool-season weeds. You could still put out pre-emergents, but you won’t get as good of an impact as you would late August to early September. Mark your calendar now to put out pre-emergent for warm-season weeds in late February to early March.

This is still a great time to do some planting or renovations to your landscape. There is still time to sod your lawn with warm-season grass. As we cool off a bit more, trees and shrubs can be planted along with perennials.

Fall is the time we think about dividing perennials, such as iris, so that they maximize their blooming. Plus, it gives you more plants to share or spread around your yard. Wildflowers, such as bluebonnets, should be sown now. You can start thinking about bulbs to put out when we get a little further along into fall. Daffodils do great here, and there are a lot of other native bulbs worth investigating.

It’s not entirely too late to put in a vegetable garden. Believe it or not, fall is a great time to grow vegetables in North Texas. It’s hard to predict when our growing season will end with a frost, but there are edibles that will do all right even after a frost.

This is also a great time to learn more about horticulture, as we have several upcoming free opportunities. At 6:30 p.m. on Tuesdays through Oct. 13, we have our lecture series at the Flower Mound Senior Center, 2701 W. Windsor Drive in Flower Mound.

The schedule begins Tuesday with Rusty Allen from North Haven Gardens talking about soil preparation and native Texas plants. On Sept. 29, Dotty Woodson will talk about veggie gardening. On Oct. 6, Master Gardener Ellen Diers will lead a hands-on class on container gardening, and the series finishes Oct. 13 with Patrick Dickinson talking about shade gardening.

Also, our annual Fall Garden Fest is scheduled from 9 a.m. to 3 p.m. Oct. 3 at Trietsch Memorial United Methodist Church, 6101 Morriss Road in Flower Mound. We will have educational booths, guest speakers, activities for children and shopping opportunities for gardeners.
