Although Japanese beetles have a wide range of favorite foods, some plants are more appealing to them than others.

The larvae seem to be especially fond of grass roots and other garden plant roots. The adults like fruit, shade trees, roses, shrubs, asparagus, corn, soybeans, and a number of other vegetables, especially plant parts exposed to the sun. They generally do not like cabbage, carrots, cauliflower, eggplant, onions, lettuce, parsley, peas, potatoes, radishes, spinach, squash, sweet potatoes, tomatoes, and turnips. They also tend to avoid geraniums.

The U.S. Department of Agriculture (USDA) has identified the following best and worst landscape plants to have in your yard when hungry Japanese beetles come calling. Use these suggestions as guidelines if you're adding new plants.

By Almanac Staff on July 28

Wisteria seldom succumbs to disease or insect pests . . . but here are a few ideas:

• it might be scales: http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn7408.html

• it might be aphids: http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn7404.html

• it might be a canker disease: http://www.ipm.ucdavis.edu/PMG/GARDEN/PLANTS/DISEASES/cankerdiseases.html

 

These are all from here (http://www.ipm.ucdavis.edu/PMG/GARDEN/PLANTS/wisteria.html).

You could call in a professional to examine your wisteria or, perhaps, take a few leaves to a local nursery and see if they can provide further information.

We hope this helps!

There is one plant they love

By John Prokos

There is one plant they love more than anything else. Marigolds. They will eat those until they are full and leave. So, encircle you garden with marigolds and they will mostly leave the vegetables alone.
