AUGUST 2020
    To keep plants attractive and in bloom continue to deadhead flowers and pinch back leggy growth.  Fertilize every two weeks with a water-soluble plant food if you didn’t apply a time-release fertilizer when you planted your containers or flowerbeds.
  When early-summer bloomers and plants that can't take summer heat cease to flower, replace them with zinnias, Indian Blanket (Gaillardia pulchella), Black-eyed Susan (Rudbeckia hirta), and other colorful plants available at garden centers this month.
  Deep water rose bushes until the middle of the month.  Then, gradually reduce watering and cease fertilization of rose bushes in order to prepare plants for winter dormancy.
  Plant fall-flowering crocus (Crocus speciosus) this month.  Bulbs should be planted 8 inches deep.  You may also plant colchicum.  This bulb is planted only 2 inches deep and blooms in the fall.
  Garden pests to watch out for this month include geranium (tobacco) budworms, whiteflies and spider mites.  Take action promptly to limit damage to plants.
   Check bearded iris plants to see if they need to be divided.  (Symptoms:  plants are 3-4 years old, clumps appear overgrown, rhizomes (bulb-like parts) in the center of the plant are sticking up out of the ground.)  Iris plants should be divided by the end of August.   
  August will bring more hot weather, resulting in thirsty lawns and plants.  Remember to water early in the morning, before 7 a.m. if possible.  If you water during the heat of the day, much of the water evaporates instead of being absorbed by the plants.  Also, avoid long watering cycles that apply more water than the soil can absorb, resulting in run-off.
  Mid to late August is a good time to seed cool-season lawns such as Kentucky Bluegrass and tall fescue.
  Wait until mid-August to fertilize Kentucky bluegrass and tall fescue lawns. Apply one pound of nitrogen per 1000 square feet of lawn. (You may delay this application until early September if you wish.)
  Buffalograss, Bermuda grass and Blue Grama lawns that weren’t fertilized in July may be fertilized in early August with one half to one pound of nitrogen per 1000 square feet of lawn.
