We’ve had several calls from customers about damage to their landscape plants because of insects. Some insects can cause temporary destruction but will not harm the overall health of a plant, while others can cause irreparable damage. We want to provide you with some resources for assessing what is happening at your home and offer help to prevent or repair the damage, so you and your family can enjoy the full beauty of your outdoor living space.
If you have rose bushes, you may have seen the return of the Japanese beetles feasting away in the last few weeks on your rose petals. While the good news is that their damage is temporary in most cases, they can ruin the beauty of your roses while they are active. Japanese beetles are attracted to many ornamental plants, and we’ve seen their damage on crabapple, cherry and linden trees in our area, among others. Learn more about their habits and prevention techniques from a report issued by The Morton Arboretum at http://www.mortonarb.org/files/Plant_Health_Care_Report_2017_7.pdf One more thing about the Japanese beetles: while traps are readily available to buy and hang in your yard, we don’t recommend them. The traps just attract more beetles to your yard, and may aggravate the problem.
Another common question is in regards to crabapple trees. Many of our crabapples are affected by apple scab this year. If you’ve noticed small black to green spots that seem to grow on the leaves or fruit of your crabapple, they may be apple scab. While unsightly and unappetizing, this fungus can cause serious damage and should not be ignored. A good way to prevent it next year is to do a thorough cleanup this fall, removing all affected leaves and branches from the tree. Don’t add them to your compost pile as the fungus can overwinter. In many cases, the tree will recover. For more information, see a report from The Morton Arboretum at http://www.mortonarb.org/trees-plants/tree-and-plant-advice/help-diseases/apple-scab
In the last few weeks we’ve received reports of damage to viburnum bushes. These popular, fragrant shrubs are a favorite in our area and we want to make sure they stay healthy for years. The Viburnum leaf beetle feeds on the leaves of the plant and will cause major damage, if allowed. They can be treated with a chemical spray in early July when adult insects are present. For more information about treating the shrub and helping to prevent the beetles next year, here’s a link to a report from The Morton Arboretum at http://www.mortonarb.org/files/Plant_Health_Care_Report_2017_8.pdf
