Wisconsin officials discovered the elongated hemlock scale pest on  live cut branches made into wreaths, garlands, and similar items being sold this holiday season at big box home retailers and nurseries. 
This infestation is reported to have come from producers in North Carolina. The products were shipped to retailers in Wisconsin.
The images above show the known range of the pest and its appearance on evergreen needles. 
It has not been found in Illinois. 
The adults suck fluid from the needles of evergreens. It is potentially destructive. 
People in Wisconsin are being advised to burn any such products or to bag them. Composting or setting out for regular trash collection is not recommended.

Here is what we planted recently in just a few minutes in Chula Vista, California.  This window box outside our dining room window was planted last May. It did not thrive. It looked nice at first. We had hummingbirds (see photo). But after the initial bloom, we had just few more flowers. The location does not receive enough sun, just a few hours mid-afternoon.  We removed the tired geraniums and replanted shade tolerant red New Guinea Impatiens.

The plants can be changed out as often you like to complement the seasons. If you live in an area with cold winters Impatiens are not appropriate now. Shop your local garden center. The will have hardy Chrysanthemums, ornamental kale, and others to keep your containers looki...
