Sudden wilting and death of individual branches of maples, redbuds and other susceptible trees may mean verticillium wilt has infected the plant.
The dead branches may occur on one side of the tree or be scattered throughout the crown. Have a professional diagnose the problem since the symptoms can be confused with other disorders.
Though verticillium wilt is fatal you can prolong the plant’s life with proper care.
Remove grass growing under the tree and replace it with a three inch layer of woodchips or other organic mulch. You’ll remove the competition for water and nutrients, while keeping the roots cool and moist. Water trees thoroughly as needed during dry periods.
Prune out dead branches as they occur. Disinfect your tools with a one part bleach and nine parts water solution between cuts to reduce the risk of spreading the disease.
Do not replace dead trees with wilt-susceptible plants
A bit more information: Do not use woodchip or leaf mulch collected from susceptible plants. These are a source of future infection. Do replace infected trees and shrubs with resistant species. Here are a few of the verticillium wilt resistant trees and shrubs to consider: Apples, crabapples, pears, hawthorns, ginkgo, hackberry, honeylocust, katsura tree, birch, beech, oak, azaleas, dogwoods, holly, and flowering quince.
Eco-friendly Control of Thrips
Poorly developed flowers, stunted plants and silvery streaks on leaves are indications thrips may be feeding on your plants.
These tiny insects have file-like mouthparts they use to puncture the outer surface of leaves, stems and flowers and suck out plant sap. They are very small and difficult to detect. Hold a white piece of paper under the plant and shake. Or remove the petals of damaged flowers, place in a sealed jar with 70% alcohol and shake the jar to dislodge and detect the pests.
Control is difficult and often not needed as the damage is discovered after the thrips have finished feeding.
Provide the proper growing conditions and care for your plants. Avoid excess nitrogen that promotes lush succulent growth these pests prefer. And remove spent flowers that tend to harbor the insects. Manage weeds in the garden and keep thrip-susceptible plants away from weedy areas where the pest populations tend to be high.
A bit more information: Beneficial insects like predatory thrips, green lacewings, minute pirate bugs and some parasitic wasps feed upon plant damaging thrips. Invite these good bugs into the garden by planting a diversity of plants and avoiding persistent pesticides. Visit the University of California IPM online for more details on this pest.

If you ever get a chance to see Milwaukee from the water...do it! I don't know what it is about the water but everything looks beautiful when you're on the water. I took these over the weekend and just looking at them calms me. We have a beautiful city enjoy it and enjoy what's left of summer:)
