Whether you apply fertilizer to your lawn, pasture, or production field, the 4R principles of nutrient management is relevant information that can be used when making applications. When making fertilizer applications, it is always important to consider if we are using the Right fertilizer source at the Right rate, at the Right time, and in the Right place.
As the calendar turns from October to November, toothy Jack-o’-lanterns start to look like deflated basketballs. This means millions of Americans need to dispose of billions of pumpkins. While many people toss these festive yet mushy winter squash into the trash, this adds an immense amount of organic material into the landfill. Typically, in a landfill, this material gets buried and rots in an environment devoid of oxygen, which creates the potent greenhouse gas methane.
The days are getting shorter, and the temperatures are finally getting cooler, meaning fall has arrived. While many of our gardening activities are starting to wind down, it’s time to start thinking about planting our spring-blooming bulbs. Bulbs such as crocus, tulips, daffodils, as well as a host of others, can provide a burst of color early in the year before many of our other landscape plants begin blooming.
As the crisp cool air of fall approaches, you might enjoy warming up with a sweatshirt or cuddling up with an additional blanket, and you are not alone! Many insects and other pests are making plans to move somewhere warm to survive the winter, and often that place is your home.
It has begun. The corn has turned. Transforming much of the Illinois landscape into a sea of tan. The soybeans are following with their yellow hues. Combines churn away, as the heavy scent of plant debris permeates the truck cab. Bright seas of goldenrod sway in the wind, as if a welcome mat laid down for autumn. Within the goldenrod mass, you may spot dots of purple asters. I was once told the colors of Western Illinois University were inspired by the fall colors of the prairie – goldenrod and purple aster.
As the calendar turns from August to September, chrysanthemums (Chrysanthemum x morifolium), aka mums, start appearing in nurseries and garden centers. These plants are a staple in many landscapes in the fall and can provide some much-needed color to our landscapes when most other garden plants are starting to decline.
Fall armyworms are here, and can you say destructive? Some entomologists have even said it is the worst they have seen in 30 years! Damage done by fall armyworms this year has been seen in lawns, hayfields, pastures, soybeans, corn, and gardens.
With a large appetite and their habit of “marching” in large numbers, FAW can do some damage in just a few days.
Working for Illinois Extension I get to travel quite often, mostly throughout west-central Illinois. And 2021 has brought a significant decline in ash trees in this area.
The Story of EAB
Emerald ash borer (EAB) is a non-native insect that attacks healthy ash trees. EAB is nothing new. I have written about this insect before, mainly when it was first discovered in the area around four years ago. Yet at that time, the effects of EAB had not yet been felt. Today it is obvious how they have ravaged the landscape.
Irises are easy to grow, long-lived, and relatively carefree perennials, making them some of the most popular flowers in gardens. They can also be found in a variety of colors, ranging from pink, purple, yellow, peach, green, white, tan, bronze, to almost black, and bi-color.
The American Iris Society divides irises into three main classifications: bearded, aril, and beardless Irises. The most common type of iris grown are bearded irises.
August is National Peach month, and who doesn’t love fresh peaches! Not only is the whole month dedicated to celebrating peaches, but we also have Eat a Peach Day on August 22nd and National Peach Pie Day on August 24th. If President Reagan was really thinking, he would have also named August National Ice Cream month because who doesn’t love ice cream with peach pie, cobbler, crisp, or just peaches by themselves!
This year has been good for many plants, but not all. In late spring Central Illinois went through almost three weeks where it rained at least once per day. Many of our plants responded to this favorably. Standing in a pollinator garden a few days ago, the goldenrod towered over me. Our vegetable gardens have seldom needed a drink from the hose. Even the grass has remained mostly green and actively growing.
Milkweeds have become a popular garden plant the last several years. They are most commonly planted to help support monarch butterflies because milkweeds are the sole food source for monarch caterpillars.
Milkweeds contain toxic compounds (cardiac glycosides) to deter animals (insects and mammals) from feeding on them. However, monarchs have evolved to be able to feed on these plants. Additionally, they can take these chemicals and incorporate them into their bodies, making them unpalatable as well.
There’s nothing more devastating than walking out to your garden to discover your squash plants are wilted or dead. An insect known as the squash vine borer is one that will cause damage to your cucurbit plants by tunneling into the stems. Once you have had an encounter with squash vine borer, it is one you will never forget.
How full is your invasive species radar? All I can say is my view is overwhelmed. Dealing with the current group of Japanese beetles, emerald ash borer, bush honeysuckle, and so many more. Plus, in Illinois, we are girding for the impending arrival of the very destructive spotted lanternfly. Then a notification arrives the USDA has prohibited the import of boxwood, holly, and Euonymus species from Canada to prevent the spread of the box tree moth (Cydalima perspectalis). I didn’t even look that one up to see what it does, but I bet it’s not good.
“I found this bug in my garden; what is it, and how do I kill it?” This is a common question that comes into extension offices. While it may seem like every insect out there is trying to eat your plants, not all the insects you see in your garden are pests. In fact, fewer than 1% of all insects are considered pests, meaning the vast majority are beneficial or, at the very least benign.
They’re back! After hitching their initial ride on imported ornamental plants in 1916, Japanese beetles decided North America isn’t such a bad place to live and have made a presence year after year since. Today, these pests can be a serious nuisance to gardeners and farmers throughout North America feeding on over 300 different species of trees, shrubs, and non-woody plants.
Landscape fabric. It’s what goes under the mulch. Right? I’ve had several conversations with home gardeners looking for a permanent solution to keeping the weeds down and each time I warn them about the use of landscape fabric.
If you’re thinking, “Hang on! Landscape fabric doesn’t work?” Of course, you’ve seen people on TV and perhaps watched professional landscapers roll out the black landscape fabric before spreading mulch. And why does every garden center sell the stuff if it doesn’t work?
After some up and down temperatures earlier this year, it seems summer has settled in for good. While a lot of the work we do in the garden happens in the spring, that doesn’t mean we can coast through the summer. Here are some things we can be doing in our landscapes to help keep them going through the summer.
Why are we talking about pumpkins in June? Because if you want home-grown pumpkins for Halloween, it is best to get them planted now!
Good Growing Fact
Did you know Illinois is ranked #1 for pumpkin production with more than 10,000 acres planted in 2019? Morton, IL, is considered the Pumpkin Capital of the World because 85% of the world’s canned pumpkin is packed there.
Fertilizer does not actually “feed” your plants. Let’s be clear, plants get their food from sunlight. I know we may have heard about photosynthesis and not paid much mind to this process. I was the same way. I remember sitting in high school biology learning about animal cells and plant cells and then hearing the teacher explain photosynthesis. Without a doubt, the term and definition of photosynthesis were placed in my short-term memory to get me through the next biology test, and afterward, it was mostly forgotten.
They’re baaaack. If you’ve spent much time outdoors recently, there’s a chance you’ve had an encounter with buffalo gnats.
With the recent detections of boxwood blight, which is a regulated plant disease, in Illinois, the importance of scouting landscapes and new plants for the disease is greater than ever. Boxwood blight can be a challenging disease to identify outside a plant diagnostic laboratory. Many of the symptoms associated with the disease are similar to other common boxwood disorders.
In 2019, the pathogen that causes Sudden Oak Death, a plant disease that has killed large tracts of oaks and affected many native plant species in California, Oregon, and Europe, was found in Illinois.
Phytophthora ramorum, the causal agent of Sudden Oak Death (SOD) was confirmed in ornamental plants at 11 stores throughout Illinois. A total of 18 states received diseased plants.
In 1946 Robert Allerton transferred the ownership of a large parcel of his estate near Monticello to the University of Illinois. The Allerton legacy gift is now used as a public park, a conference and retreat center, and a 4-H youth camp.
Now, 75 years later, nearly all of its 1,600 woodland areas are challenged by invasive plant species presenting many challenges to the professionals entrusted to its care.
The Asian longhorned beetle is a non-native pest that threatens a number of hardwood trees in North America. The larva damage living trees as they tunnel through.
Spotted lanternfly (Lycorma delicatula) is a newer invasive pest in the United States that has the potential to become a serious pest across a large part of the United States, including Illinois.
What do they look like?
Adult spotted lanternflies are about 1 inch long. The front pair of wings are gray with black spots, and the tips of the front wings have speckled bands. The back pair of wings are red with black spots and a white band. Their heads and legs are black, and the abdomens are yellow with black bands.
Palmer amaranth is an invasive weed species we have been hearing a lot about in agriculture over the last 10 years, and it continues to be a threat after its first documented appearance in Illinois in 2012. Native to southwestern US states, palmer amaranth has made its way to 39 of the states.
When we look at the current lists of plants that are deemed legally invasive by state and federal governments, we see species that were quite popular in the landscape in generations past. As we battle the current invasive species in our natural areas, there is a new generation of non-native shrubs that are currently quite popular in the home landscape which we are now seeing escape cultivation into the wild. Here are three shrubs that are recommended to avoid or remove.
When it comes to invasive insects, much of our attention is directed towards those that cause a great deal of damage, such as Japanese beetles and emerald ash borer. However, there are some other invasive insects present in Illinois that pose a threat to our plants and even us that you should be aware of.
Emerald ash borer (Agrilus planipennis) or EAB has cut a wide swath of destruction across a large portion of the United States, including Illinois. EAB has been responsible for the death of tens, if not hundreds, of million ash (Fraxinus spp.) trees, which has led to drastic changes in some communities and landscapes.
With our recent warm weather, you have probably started noticing your landscape plants really taking off in growth. For those with a more established landscape, this boost in growth may have you noticing some of your perennials crowding out others or taking over. If this is the case, it may be time to consider splitting your plants.
Why Should We Divide Perennials?
A tree is a long-term investment for a home. Truthfully, we often don’t plant trees for us, but for those that come after us. But many trees planted in a developed area don’t live past their eighth year. Here are some tips to help get your new tree past the eight-year hump and keep it going for generations.
Have you ever noticed small white flowers dotting the landscape this time of year? Chances are they’re spring beauties (Claytonia virginica). While they may not be the first wildflowers to bloom, spring beauties are one of our earlier blooming wildflowers and a sure sign that spring has arrived. Individually, these wildflowers may not be the most impressive plants out there, but when growing in large masses, they are a sight to behold.
The year of 2020 brought a new experience for many as over 20 million novice gardeners picked up a trowel for the first time according to Bonnie Plants CEO Mike Sutterer. New adventures come with excitement; however, as those rose-colored glasses become clearer with further attempts and another year of gardening, the frustrations and failures can grow. Therefore, we have come up with some tips to help those 2nd time growers stay optimistic.
It is heartbreaking to see the results of natural disasters, when it affects entire communities or when the storm hits home. As a horticulture educator, I am often asked in the aftermath of a weather-related disaster, “How do we restore our landscape?” This may seem like a trivial question in such times, say when a community is recovering from a tornado, but each time a person steps outside their home and is greeted by a ravaged landscape, they will be reminded of the disaster.
Asparagus is one of the few perennial vegetables that is commonly grown in gardens. But don’t let that intimidate you - it’s a relatively easy crop to grow. However, you’ll need to exercise some patience when growing asparagus.
Our fool spring has many itching to get out in the yard and get to work sprucing up the lawn; however, it is important to consider that it could still be too early. To properly take care of problems in the lawn, it is important to fully understand what we are trying to control.
Spring lawn maintenance often includes a combination of the following: a pre- or post-emergence herbicide, overseeding, aerification, dethatching, fertilization, or an insecticide. When making these applications, it is important to apply maintenance practices at the right time.
It feels like spring has sprung and boy it sprang hard. Despite the dizzy use of the different forms of “spring”, Illinoisans can relate. Several days above sixty and even a few above seventy degrees in early March has pushed growth in many early perennial plants. Buds on trees and shrubs are swelling ready to pop at a moment’s notice. Many of our cool-season vegetables have also put on significant growth. And yet, by the time this article is printed, we will likely be back to more seasonable spring weather. Chilly, rainy, and mud…everywhere.
Butterflies are among the most popular, if not the most popular, insects out there. In fact, many cultures around the world use a butterfly as a symbol of the human soul. Many people consider a butterfly landing on you to be good luck, for example, this Irish blessing:
Ooooh that smell. Can’t you smell that smell (read to the tune of That Smell by Lynyrd Skynyrd). If you have been driving around the countryside recently, you might already know what I am talking about; however, for those of you that don’t, as the temperatures warm up, a foul smell may begin floating around select farmer’s fields. Some say it smells like a gas leak while others might give their vehicle companion a nasty look, but the true culprit is the radish.
I love winter. I love snow. However, I must add two caveats to my initial statements – I love winter and snow as long as I am warm and I can stay at home. It’s when my feet get cold or my car is fishtailing trying to turn a corner that winter weather goes from fun to miserable.
When you turn on the news, radio, or talk with your neighbor people are getting rather irritated with winter. With all this complaining about our cold snowy weather, is there any benefit to winter when it comes to our yards and gardens?
There are many different stories as to how we came to celebrate St. Valentine. Some stories say Valentine was a priest that secretly wed young couples. Others say he helped Christians escape prisons before being imprisoned himself. Before being put to death, he wrote a love letter and signed it “From your Valentine,” which is still used to this day.
Trees in the landscape can be easily overlooked for the all the benefits they provide us whether that be casting shade on a warm, summer day, housing our feathered, birds friends, or adding a touch of color to our lawns. According to the Council of Tree and Landscape Appraisers, trees on a property can increase the value of a home by almost 20%. However, that value can be diminished when trees are not properly maintained through pruning and thinning.
People love to feed birds. Aside from gardening, it is considered one of the most popular hobbies around the globe. And even some would argue, feeding the birds is a part of gardening. In the winter months, many find joy in watching a flurry of feathered friends, feeding at the feeder. The bird food we set out helps to give those birds that stick around Illinois over the winter an energy boost to keep their body temperatures up on these cold days.
It’s that time of year - time to start thinking about pruning your deciduous trees. Most deciduous trees are best pruned while they are in full dormancy. This happens to be January to early March for this part of the country.
Being two weeks into the new year, I hope those of you with new goals of healthier eating are still going strong. If things didn’t work out the way you had planned, no worries; vermicomposting can help you get rid of all those fruits and vegetables that have gone bad and provide a nutrient rich material that can be added to our plants. Vermicomposting is the process of using various species of worms to decompose organic waste such as food scraps. It is also a great option for winter composting when our outside pile has become dormant.
As I type out this article, I can’t stop thinking about my drive to work today. After days of clouds, ice, snow, and more clouds, the sun shone brightly as it crept over the eastern horizon. As sunbeams edged further across the landscape the trees became illuminated with a rainbow of light. It was spectacular!
