Three simple techniques transform prized flowers into beautiful home decor

Your garden's floral showcase may be ending but the flowers need not disappear. Extend the life of floral garden favorites by preserving them for indoor decor.

Choose local foods this Thanksgiving

Celebrating the year’s crops with a Thanksgiving feast has been a tradition for over 400 years. Likely in 1621, individuals fed their families and communities by growing vegetables in the field. This past summer, Illinois residents went to farmer's markets despite pandemic conditions as America continues to demand locally sourced vegetables and increased access to healthy food.   “Locally grown food isn’t shipped thousands of miles, which reduces the carbon footprint, supports our local...

What you should know about Burning Bush

The glow of the intense bright red color, corky ridges on the branches, and bright orange or red berries  of your neighborhood burning bushes may entice you, but remember planting and growing them will lead to further degradation of the Illinois wildscape. The ornamental berries of this common landscape plant spread aggressively by birds and other wildlife in the understory of our forests and outcompete native plants.

Put your garden to bed with fall/winter cover crops!

Like it or not, fall and winter will be here before we know it! During the off-season, too many gardeners leave their vegetable or flower gardens bare over winter. This can cause major problems for the following growing season, especially an invasion of winter weeds and erosion of high-quality topsoil to boot. Beat the weeds and hang on to your soil this fall, winter and spring by planting a cover crop, or at least putting down some straw.  In case you missed it,...

Monarch butterflies facing a crisis

BLOOMINGTON, Ill. – The state insect, the monarch butterfly, is facing a crisis. Each May, Illinoisans celebrate the monarch butterfly, but University of Illinois Extension Horticulture Educator Kelly Allsup says that Illinois residents should be worried. The yearly count of monarchs decreased by 53% in 2019 from the following year, says Allsup. "This most recent drop may not be directly correlated to our reduced milkweed numbers; drought and other environmental factors are also contributing...

Herb of the Year: Parsley

A recent study tracking butterfly abundance in Ohio over the last 20 years has discovered a 33% decline.

Scientists believe the decline may be attributed to climate change, habitat degradation, and agricultural practices.  With this news on your mind, what if I told you there was a plant that could go in your garden...

How do you bring an office plant back to life?

  When people walked out of their workplaces last March, most did not think it would take a year to come back.   While working from home, I missed my office.

Divide and Conquer in Fall

If you have a vigorous perennial that has been in the garden bed for more than a few years, or it is starting to choke out some other plants and no longer looking healthy, then it may be time to divide. Plants that need to be divided cannot support healthy foliage and flowers. Some perennials like to be divided yearly (chrysanthemum); some can go three to five years without division; some can go much longer. Some do not require division at all, like butterfly weed with the taproot, or baby’s...

ZZ Plant is a Tropical that Thrives Indoors

Originally published by Kelly Allsup on April 16, 2020. Most homes have insufficient light, inconsistent temperatures and tap water containing fluoride — all of which make it nearly impossible have lush foliage during the winter months. However, most tropical houseplants can be sustained and even thrive in these conditions. Houseplants such as devil’s ivy, dieffenbachia, and peace lily do very well with low light and temperatures that are not the ideal 75 to 80 degrees. However,...

Not All Trees Are Good Trees

In the world of landscaping, trees are the backbones of the landscape. They are permanent structures that have stately features, shade our homes, provide spring floral displays, and some amazing fall color. There are, however, some trees that just behave badly. You’re likely familiar with maples that drop their helicopter seeds (known as samaras) all over the neighborhood, sprouting up scattered shoots in our lawns and flowerbeds—hard to call this a bad tree with the fun they bring to children...

Ornamental Fall Berries Provide Year-Round Awe

Have you ever heard a horticulturists encourage the use of plants having “multiple seasons of interest”? This might be said in response to someone’s complaints about forsythia, for example. Forsythia blooms in spring, an explosion of lemon-yellow blossoms covering the plant. But the rest of the year, it is drab and unruly. The unruliness causes many gardeners to shear the shrub into boxes (completely unnecessarily) and then when spring comes again the flower display is subpar and sparse—one...
