August Garden Tips

First Week  

  • Getting late to root cuttings of shrubs and houseplants for propagating. You’re on the margin.
  • Divide daylilies.
  • Getting a little late also to plant summer grasses.
  • This is the last month to fertilize Centipede and St. Augustine.
  • Give ferns a light feeding now if you plan to bring them in for the autumn.

Second Week 

  • Remove faded Crape Myrtle blooms.
  • Pick bagworms from Juniper and Leylands and dispose of them off the property.
  • Set out plants of lettuce, cabbage, collards and broccoli.
  • Keep an eye out for poison ivy/oak. Spray with Round Up or Brush-B-Gone.  One application won’t get it. Give it three, every ten days.

Third Week 

  • Time to start thinking about fall composting with “weed/disease free” grass clippings and faded flowers.
  • Continue watering, one inch, once a week if drought is still with us.
  • Keep an eye out for Lace Bugs on Azaleas and Pyracanthas. Use insecticidal soap or diazinon if you still have some.

Fourth Week

  • Raise lawn mower one notch to keep grass shaded and conserve water.
  • Keep Azaleas and Camellias well watered.
  • Dig and store Gladiolus corms as soon as the tops turn yellow if you plan to store them.
  • Hold off until September to start fall grass planting.
  • Whatever you do read the label and follow the manufacturer’s instructions!
