Illinois-Indiana Sea Grant Newsroom: During large rainstorms, many Illinois residents brace themselves for flooding in their basements, streets and neighborhoods. A new online tool, Illinois Groundwork, provides communities and stormwater professionals with resources on green stormwater infrastructure, which provides a way for rain to be absorbed into soil where it lands.

Green stormwater infrastructure offers a way to enhance traditional or “grey” infrastructure using a rain garden or permeable pavement but this approach doesn’t always work as well as it might. Improving access to, and use of, data, research and other resources can help increase the effectiveness of green infrastructure in addressing stormwater management challenges.

“The University of Illinois not only has relevant research and data across many departments, but also real-world examples of successful green infrastructure, along with other extension and education tools, such as the Red Oak Rain Garden,” said C. Eliana Brown, University of Illinois Extension stormwater specialist. “This new tool brings these resources together, providing a robust platform to access green infrastructure knowledge.”

Illinois-Indiana Sea Grant Newsroom: May 2022, Illinois-Indiana Sea Grant (IISG) launched its third buoy in southern Lake Michigan—this one based in the busy waters off Navy Pier. This new buoy with its flow of in-the-moment data is helping the National Weather Service (NWS) Chicago develop more accurate forecasts and warnings, especially related to nearshore wave heights and wind speeds.

This third buoy, known affectionately as Chuoy, joins IISG buoys in the nearshore waters of Michigan City, Indiana and Wilmette, Illinois. Together, these three, along with two University of Illinois buoys closer to the Wisconsin border, paint a comprehensive picture of coastal lake conditions in the two states. In addition to meteorologists, the data is used by scientists, boaters, anglers and beach goers.

“Information from these buoys allows recreational water users to make better informed decisions when it comes to safety,” said Ben Szczygiel, IISG buoy specialist. “The data allows people to plan for current conditions and avoid the water when there are increased safety concerns.”

MyDNR, Indiana’s Outdoor Newsletter: The Indiana Natural Resources Foundation, in partnership with the Division of Forestry, is planning another busy year for the Indiana Tree Project. In 2022, more than 11,000 trees were added to Indiana’s public lands through Indiana Tree Project plantings, and this year is expected to be another successful year.

Through a partnership with the Division of Forestry, we are helping Indiana’s forests grow, one tree at a time, with the Indiana Tree Project. Healthy forests in Indiana promote wildlife habitats, clean air and an abundance of outdoor recreation opportunities. It is estimated that 85 percent of Indiana was once forested. Today, only 19 percent of the state is forested. The Indiana Tree Project is much more than just planting trees. Through this project we are adding new acreage to Indiana’s State Forests and we’re trying to add 1,000 acres of new forested land.

When you support the Indiana Tree Project, we provide you with an official tree certificate to demonstrate your support for the smart management of Hoosier forests. It includes the coordinates for the acre on which your tree is, or will be, planted.

Newsletter can be found online: MyDNR Email Newsletter

Purdue Landscape Report: It’s that wonderful time of year again where temps are rising, life is coming back into the landscape, and people are thinking about how to improve the urban canopy around them.  Well, maybe not that specifically, but we have the urge to plant trees.  Whether it’s for Earth Day or Arbor Day or you just enjoy the act of planting, one of the hot topics is getting trees into the ground.  That’s not what I’m here to talk about today, though.

As much as I love assisting communities with their greening efforts, getting the right tree in the right place, planting is not the only way to help grow the canopy around you.  One of the topics that can be neglected is maintaining trees from previous plantings.  Often, trees get placed in the ground, they are mulched, watered, and staked, then left on their own to make it in the world.  New trees can take about 2-5 years to become established in their new homes and they could require assistance from us for much longer to thrive.  Luckily, there is a simple activity to do assist trees, young and old.

Just like when they were placed in the ground, trees still benefit from mulch.  Reapplying mulch benefits trees in multiple ways.  It’s a natural way to prevent weeds and grass competing in the root zone and adds a protective buffer against mechanical damage from mowers and weed eaters.  It will also help to maintain moisture levels in the soil as we transition into the hotter summer months.  When applying new mulch, don’t worry about removing the old layer.  It’s working its way into the soil around the tree adding organic matter, improving the quality of the soil.

Add enough mulch so there is a 2–3-inch layer sloping away from the tree with at least a 3–5-foot radius around the stem (older, larger trees can benefit from larger mulch rings).  No volcano mulching (Figure 1), make sure you also have around a 1-2-inch gap between the stem and the start of the mulch ring (Figure 2) to prevent unwanted root growth above ground and rot from excess moisture on the stem.   Continuing this practice every year can help maintain soil moisture levels, while enriching the soil around your tree, maintaining a safety zone, and adding a nice aesthetic.

Purdue Landscape Report: Pseudomonas syringae pv. syringae is an opportunistic bacterial pathogen that attacks a diversity of woody ornamental plants. The bacteria cause flower blights, cankers, shoot blights, and diebacks.

Symptoms
Symptoms often begin as expanding leaf spots. On lilac and viburnum, small spots expand to irregularly shaped brown lesions with yellow halos (Fig. 1). For most other hosts (cherry, pear, basswood, dogwood, hydrangea, high bush-cranberry, mountain-ash), infected leaves turn reddish brown or black and usually remain on the branch after they die (Fig. 2). As the bacteria spread into woody tissue, dark, sunken sections of the stem (cankers) expand, working their way back toward the trunk from infected leaves and flowers. Leaves attached to a cankered branch will wilt while the tip of the affected branch curls and droops like a shepherd’s crook (Fig. 3). Cloudy droplets of sticky fluid (ooze) may accumulate on leaf tips, leaf surfaces, stems, and even infected fruit.

Image of infected flowers result in blossom blast.
Figure 2. Infected flowers result in blossom blast. The continued growth of the bacteria can result in cankering and blight. Photo by George Sundin.

Life Cycle
The bacteria overwinter and persist in cankers, along with asymptomatic bud and twig tissue. In presence of water and warming temperatures, bacteria multiply and may ooze from infected tissue. Wind-driven rain, insect, or mechanical pruning spread Pseudomonas. Bacteria enter the plant through flowers or injury.

Management
All bacterial pathogens, including Pseudomonas, invade flowers or wounded tissue. To prevent or minimize the risk of infection:

• Use disease-free plants and budwood.
• Prune in the late winter/early spring.
• When pruning, do not mix pruning to shape woody ornamentals with pruning to manage disease.
• When pruning to remove infected shoots, be sure to disinfect shears between plants.
• Minimize overhead irrigation when possible to minimize splashing and pathogen spread.
• Avoid over-fertilization practices that drive excess succulent growth.
  

  Figure 3. Bacterial blight is a common scourge to common lilac. Using resistant varieties is the best way to protect against the disease. Photo by Janna Beckerman.

• Avoid late season fertilization practices that prevent plants from achieving timely dormancy and promote freeze damage and/or winter injury (Fig. 4).
• Choose zone appropriate plants to avoid freeze damage and/or winter injury.
• Choose disease resistant plants, when available. The following lilac varieties were found to be resistant over a four-year trial: Donald Wyman, Royalty, Superba, Miss Kim, Edmund Boisier, Victor Lemoine, Dwarf Korean, Mme. Antoine Buchner Isabella, Sensation, Anna Amhof, Krasavitska Moskvy, Michael Buchner, and Alphonse Lavallée.

Foliar sprays of some copper-based bactericides (e.g., Camelot, Kocide, and Nu-Cop) were found to reduce disease incidence in trials on lilac (Vey and Palmer, 2018). Avoid using copper under cool, humid conditions to reduce the risk of phytotoxicity and damaging plants. Copper resistant populations of Pseudomonas syringae have been reported in other crops (vegetables, stone fruit). Products containing acibenzolar have provided inconsistent control in multiple trials but is labeled for use. Use of quaternary-ammonium disinfestants (KleenGrow) have been found to reduce bacterial populations and disease incidence and should be considered as part of any rotation with copper products. Due to the diversity of copper products, be sure to test for phytotoxicity issues prior to large scale treatment of crops.

This exotic invasive tree species is commonly found in Indiana landscape, callery pear. Callery pear has been planted as an ornamental tree in the midwest for decades. The original selection bradford pear was actually infertile and would not spread from seed but additional varieties have been planted and have crossed with the original Bradford and those are producing fertile seed. Find out how the seed spreads and what we can do to help our forest.
