Mulching flowerbeds improves soil texture.
Deadhead phlox, yarrow, and daylilies for rebloom.
Trim brown foliage from bleeding heart and peonies and discard.
Take root cuttings of azelea , holly and hydrangea.
Order bulbs for fall planting.
Peonies can be moved this month but must be watered well.
During the hot and dry weather of August, try to water early to minimize water loss from evaporation.
Avoid deep cultivation in your flower beds when the weather is hot and dry because loosening soil under those conditions reduces water uptake by increasing loss of soil water and damaging surface roots.
Freeze herbs in water- chop fresh herbs, place in an ice cube tray, cover with water and freeze in a plastic bag - to create a tasty flavor cube to add to soups and stews.
As always, keep your tools clean and clean your tools as you move from plant to plant.
