“It’s September”… what needs to be done?
- Plant these fall vegetables now: beets, carrots, “greens” (mustard, collard, turnip), kale, lettuce, radishes and spinach.
- Lawn establishment using warm-season grasses such as Bermudagrass, St. Augustine, zoysia and buffalo grass should be completed early in the month.
- Overseed established Bermudagrass lawns with perennial ryegrass this month, if desired.
- Plant these fall-blooming annuals from bedding plants before buds have opened: marigolds, petunias, asters, pinks, snapdragons and mums. Wait until cooler weather to plant pansies, violas and ornamental cabbages and kale.
- Complete sowing bluebonnets to ensure spring flowers. For season-long color, purchase a wildflower mix that contains annuals and perennials, as well as cool-season and warm-season plants such as bluebonnets, black-eyed Susan, Indian blanket, Indian paintbrush, Mexican hat, plains coreopsis, purple coneflower and evening primrose. Sow seeds in areas that are free of grasses and lightly tilled. Lightly rake area to get good seed-soil contact before watering.
FERTILIZING AND PRUNING
- Apply high-nitrogen fertilizer (4-1-2 ratio) on lawns and shrubs to prepare plants for fall and winter. Container plants will benefit from using high-nitrogen, water-soluble fertilizers.
- Tidy up summer perennials by removing dead and faded flower stems and seed stalks. Continue through fall.
- Root-prune trees and shrubs to be transplanted this winter. Cutting the roots around the plant with a spade will stimulate new root growth in what will become the soil ball when the plant is moved.
- Apply a pre-emergent herbicide to lawns early in the month to control winter weeds. Depending on the type of weed targeted, it may be necessary to apply two products — one for grassy weeds (annual bluegrass, ryegrass, etc.) and another for broad-leafed weeds (chickweed, clover, dandelions, henbit, etc.).
- Make final application of Image® or SedgeHammer® before mid-month to control nutsedge in warm-season lawns.
- Remove webworms from pecan trees. Cut off the ends of branches as soon as the webs appear. Tear open large webs to expose worms for birds. Spraying is not practical.
- Spray roses suffering from black spot and powdery mildew with labeled fungicide.
- Prepare beds for spring-flowering bulbs. Add organic matter to improve water drainage.
EXTREME GARDENING TOPICS:
- Extreme Invasion – Cricket outbreaks are one of the most predictable pest events of the year in most areas of Texas. Known as black field crickets, or just field crickets, outbreaks occur when large numbers of nymphs complete their development and embark on nighttime mating flights. Reducing outdoor lights is the first and most important step in a cricket control problem. Also, tightly seal all potential points of entry into buildings.
