Plant Trees and Shrubs
Now is a good time to add new trees and shrubs to your landscape, and bargain prices are popping up at your local nurseries and garden retailers. Plant early in the autumn while the soil is still warm to ensure plant survival. Dig the hole two to three times wider than the root ball.
Spray for Mildew
That white powdery substance on the leaves of lilacs and other shrubs is a disease known as powdery mildew. It can be safely and easily controlled with a common kitchen item: baking soda. Mix up 2 to 3 teaspoons per gallon of water and spray on the foliage. This will keep the disease spores at bay and reduce the incidence of this unsightly disease.
Don't give up the battle against weeds in your yard and garden. Keep pulling and digging weeds before they have a chance to go to seed. What you get rid of now will reduce the spread of seeds that can overwinter and grow back next season.
Plant Perennial Flowers
Perennials are on sale at local garden centers and nurseries. They can be planted to fill in those open areas of your perennial bed. Soak the plants well before planting to help them make the transition to their new homes. After planting, mulch with a 2-inch layer of compost or shredded cedar mulch to encourage strong root growth.
Be on the Alert for Wasps and Yellow Jackets
Now is the time that young wasps and hornets are out and about. They can be aggressive and sting when provoked. Set out wasp and yellow jacket traps to avoid a confrontation. Use a wasp spray if necessary to eliminate nesting sites under the eaves of your home.
