This is a good month to prune your azaleas, forsythia, dogwood, redbuds and rhododendrons.
Keep a good eye on your plants water needs now. August is one of the hottest months of our year. Container gardens will dry out faster now. Small containers might have to be watered twice a day. Keep in mind that it's better to wake your plants up wet and put them to bed dry!
Pick fresh flowers for your home from your perennials. It will help in promoting new blooms and add a touch of your outside garden indoors.
Order your spring blooming bulbs now for planting this fall. Keep pruning your cannas to prolong the bloom-time.
When either annuals or perennials get scraggly, cut them back about 1/2 way and fertilize. Continue to water them and as the days start to get cooler they can bounce back and give you some more color.
