Purdue Landscape Report: The last week has caused many to struggle with whether to turn the heat on inside.  Mornings have been quite chilly, and I am guessing several readers may have also struggled with the decision to wear a jacket as they started their workday.  These are tough decisions, no doubt.  Several data sources have suggested we have had at least 2 weeks of consecutive below-average daily mean temperatures.  While not a record, this is certainly noticeable!  Perhaps we are hoping those tomato plants will produce just a few more tomatoes.  Is it mum season, already?  The good news – for those not quite ready to say goodbye to warm days, not needing coats, and garden delights – is warm temperatures are expected to return.  Daily high temperatures are already in the 80s and Indiana is likely to see temperatures in the mid-90s by next week.  There is significant confidence that this warmer-than-normal temperature trend is likely to continue through most of September.  Average high temperatures typically range from 75°F – 85°F in mid-September and 70°F – 75°F in late September, so keep in mind climate outlooks are all relative.  Indiana is not likely to experience triple-digit heat waves over the next few weeks, but nighttime low temperatures are likely to fight for temperatures warranting a sweater or jacket.

Regarding first frost or even hard frost, we are still too early in the calendar year to worry about this being an extensive risk.  Very localized, low-lying areas may be susceptible, but the climatological average date of the first hard freeze (28°F) is often not until mid-to-late October (Figure 3). With temperatures expected to warm again, widespread hard frost is not anticipated prior to October.

Illinois-Indiana Sea Grant (IISG) have four buoys now in place on the Great Lakes which inform scientists, weather forecasters, anglers, boaters, paddlers, surfers, swimmers and educational programs about current lake conditions. They collect data on wind speed, surface current, wave height, and water temperatures, providing valuable insights for scientists and the public.

1. Michigan City Buoy – This buoy is located three miles offshore of Michigan City, Indiana. Purdue University’s Lyles School of Civil Engineering created the anchor used to keep the buoy in place. They also maintain and help deploy this buoy each year. The Michigan City Port Authority and the Lake Michigan Indiana Department of Natural Resources office played pivotal roles in helping deploy the anchor. The buoy itself was funded through a grant provided by Illinois-Indiana Sea Grant. A grant from the Indiana Department of Natural Resources Coastal Management Program allowed for the addition of the temperature chain.
2. Chicago Buoy – This buoy, also called Chuoy, is based in the busy waters off Navy Pier, approximately a mile due east of the pier. This buoy is jointly owned and operated by Illinois-Indiana Sea Grant and the Lyles School of Civil Engineering at Purdue University.
   For more information about Chuoy, check out this IISG article: New to Navy Pier waters, Chuoy the Buoy Proved a Valuable Forecasting Tool.
3. Wilmette Buoy – The Wilmette Buoy is situated approximately four miles off Wilmette, in Lake Michigan. The Sheridan Shore Yacht Club and the Coast Guard in Wilmette help deploy and store this buoy each year. Henry’s Sports and Bait shop in downtown Chicago helped deploy the anchor. The buoy was first deployed through a grant from the Great Lakes Observing System and the NOAA Coastal Storms Program.
4. Waukegan Buoy – The Waukegan buoy is situated about a mile offshore from Waukegan Harbor in Lake Michigan. This buoy is owned and operated by the University of Illinois and the Illinois State Geological Survey. LimnoTech, Inc. and Illinois-Indiana Sea Grant play pivotal roles in helping deploy and support the buoy. The buoy was first deployed through a grant from NOAA. Continued funding support comes from the Illinois Department of Natural Resources Coastal Management Program.

“The buoys act as a service to people who are active in Lake Michigan,” said Tomas Höök, director of Illinois-Indiana Sea Grant and professor of Forestry and Natural Resources at Purdue University. “A line runs from the surface of the buoy to the bottom of the lake, and sensors collect a variety of data. The buoy’s modem then communicates with a cell tower, providing data that anyone can access in real-time.”

“Near-record high water levels a few years ago were causing erosion along the shoreline, and there were even cases farther north in Lake Michigan of houses falling into the lake. But if you look back about 10 years, near-record low levels made the shoreline look like a mud flat,” Höök explained. “It’s important to understand because if infrastructure is built while the water is low, it’s highly likely the water level will rise back up and threaten that infrastructure.”

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.”

Purdue Landscape Report: The hard freeze April 20th & 21st had many homeowners concerned about their perennial and annual plants in their landscape.  For the vast majority of perennial plants, there aren’t many issues long-term of concern.  Some foliage and flowers have significant damage, but the plants will recover, and possibly release new vegetative buds in severe cases.  The plants that suffered the most damage, and in some cases death, are the annuals planted by impatient landscapers and gardeners.  Planting annuals prior to the frost-free date (May 10^th in central Indiana) will more than likely cause a replant to occur.

In addition to the potential stress from the temperatures, many trees received broken limbs due the combined weight of the leaves/flowers and snow load.

If you maintain a client’s fruit trees (i.e. apples), there may be a significant impact on fruit production.  The Purdue Meigs Horticultural Research Farm, located about eight miles south of the West Lafayette campus, recorded a low temperature of 22^o F on April 21^st.  Dr. Peter Hirst, pomologist, indicated that at the current stage of flowering a temperature of 25^o F might result in a 90% bud kill.  Since there was a significant snowfall, the hope is that there was some moderation in temperatures.

Illinois-Indiana Sea Grant (IISG) Newsroom: With the prolonged pandemic continuing to affect the United States, traditional education has turned toward at-home learning and virtual classrooms to keep students safe. Now more than ever, teachers must be able to find lesson plans for their students that are adaptable to different learning environments and cover topics required by the curriculum. To meet these needs, Illinois-Indiana Sea Grant (IISG) has created a weather and climate education toolkit where teachers can find resources on the topics of weather, climate and climate change.

IISG developed the weather and climate education toolkit with support from the Center for Great Lakes Literacy and the Midwestern Regional Climate Center.

Purdue Landscape Report: Just as sure as you try to predict the weather, it is likely to change. But going out on a limb, I predict that we will have a bit of a dud for fall color display this year. Not a very risky prediction, considering that many plants already are starting to turn color and/or drop leaves in some areas of the state.

So why would the colors be early and/or a bit duller than usual? Certainly, some of the reason why plants display fall colors has to do with the genetic makeup of the plant. That doesn’t change from year to year. But the timing and intensity of fall colors do vary, depending on factors such as availability of soil moisture and plant nutrients, as well as environmental signals such as temperature, sunlight, length of day, and cool nighttime temperatures.

The droughty conditions experienced during much of the second half of summer are likely to have decreased the amount of fall color pigment. Southern Indiana has been particularly parched. Despite recent rains in some areas, much of the state remains designated as abnormally dry to moderate drought. You can check your area’s conditions at the US Drought Monitor for Indiana. Additional maps and data is available at the Midwest Regional Climate Center.

Growing conditions throughout the season affect fall color as does current weather. Colors such as orange and yellow, which we see in the fall, are actually present in the leaf all summer. However, those colors are masked by the presence of chlorophyll, the substance responsible for green color in plants during the summer. Chlorophyll allows the plant to use sunlight and carbon dioxide from the air to produce carbohydrates (sugars and starch). Trees continually replenish their supply of chlorophyll during the growing season.

As the days grow shorter and (usually) temperatures cooler, the trees use chlorophyll faster than they can replace it. The green color fades as the level of chlorophyll decreases, allowing the other colored pigments to show through. Plants that are under stress–from conditions like prolonged dry spells–often will display early fall color because they are unable to produce as much chlorophyll.

Yellow, brown and orange colors, common to such trees as birch, some maples, hickory and aspen, come from pigments called carotenoids, the same pigments that are responsible for the color of carrots, corn and bananas.

Red and purple colors common to sweet gum, dogwoods and some maples and oaks are produced by another type of pigment called anthocyanin, the pigment responsible for the color of cherries, grapes, apples and blueberries. Unlike chlorophyll and carotenoids, anthocyanins are not always present in the leaf but are produced in late summer when environmental signals occur. Anthocyanins also combine with carotenoids to produce the fiery red, orange, and bronze colors found in sumac, oaks, and dogwoods.

Red colors tend to be most intense when days are warm and sunny, but nights are cool–below 45º F. The color intensifies because more sugars are produced during warm, sunny days; cool night temperatures cause the sugars to remain in the leaves. Pigments are formed from these sugars, so the more sugar in the leaf, the more pigment, and, thus, more intense colors. Warm, rainy fall weather decreases the amount of sugar and pigment production. Warm nights cause what sugars that are made to move out of the leaves, so that leaf colors are muted.

Leaf color also can vary from tree to tree and even from one side of a tree to another. Leaves that are more exposed to the sun tend to show more red coloration while those in the shade turn yellow. Stress such as drought, poor fertility, disease or insects may cause fall color to come on earlier, but usually results in less intense coloration, too. And stress or an abrupt hard freeze can cause leaves to drop before they have a chance to change color.

So far, weather conditions lead me to think this will be one of those not so showy fall color years. I hope I am proven wrong!
