Dry summers are not that unusual in the Midwest. But this year the dry spell followed an unusually wet spring and early summer in many areas. Of particular concern this year is that the dry spell is lasting well into autumn, putting plants in poor condition to get through the winter when water will be unavailable due to frozen soil. Newly planted trees, shrubs and perennial flowers will be at most risk of winter injury […]
If thinking about the end of summer is getting you down, it’s time to plan and plant your spring flowering bulb show. Autumn is the time to plant crocus, daffodils, tulips and many other spring bloomers. Spring flowering bulbs are planted in the fall to allow them to establish roots before top growth begins in spring. Planting too early may cause the bulbs to sprout this fall, only to be killed back by winter weather. […]
Much to the dismay of homeowners, landscape trees sometimes grow roots on top of the surface of the lawn or possibly even buckle sidewalks and driveways. These surface roots can be quite a nuisance to lawn mowers and human feet. There are several reasons why the roots come to the surface. Some tree species are more prone to surface roots than others, most notably silver maple, poplar and willow. But almost any large, older tree […]
Trees and shrubs with colorful foliage can add a steady supply of interest in the landscape throughout the growing season. Purple foliage is quite popular among plant breeders and garden enthusiasts. Here’s a look at some possibilities to consider. Small to Medium Trees Japanese Maple – There are many cultivars available in the trade. Some have purple foliage all summer while others may be purple only in spring and/or autumn. Redbud “Forest Pansy” – This […]
Pollinators are all the “buzz” these days with a federal proclamation designating June 15-21 as National Pollinator Week. Now in its eighth year, the focus of this event is to promote the health of pollinators, so critical to food and ecosystems. It may surprise you to learn that the honeybee is native to Europe and was introduced to the US. But there are also numerous other pollinator species including native bees, butterflies and moths, beetles, […]
Although late winter is generally the ideal time for pruning chores, many of our spring-blooming shrubs are best pruned immediately after flowers have faded. Trees and shrubs that bloom in early spring, such as forsythia, lilac, honeysuckle, quince and spirea, set their flower buds the previous fall, referred to as “flowering on old wood.” If you prune in late winter, some or all of the bloom potential for spring is sacrificed. By waiting until after […]

The National Garden Bureau has declared 2015 to be the Year of the Sweet Pepper! Sweet bell peppers are cultivars of Capsicum annuum. Sweet peppers are called sweet because they lack the gene that produces capsaicin—the chemical that gives hot peppers their heat. Pepper plants are easy to grow, and are quite compact making them a good fit for limited-space gardens and containers. Peppers are warm-season crops and should be planted out in the garden […]
It’s not often that a new vegetable comes along, so I’m really looking forward to trying the new Kalettes this year. Developed in Great Britain, where they are called Flower Sprouts, this new vegetable is a hybrid cross between Brussel sprouts and kale. The result is beautiful. They resemble miniature, ornamental kale rosettes with purple highlights on dark green, leafy buds growing in the leaf axils along the stem – just like Brussel sprouts. Kalettes […]
Although sometimes referred to as clover, the shamrock is not a “true” clover but more typically one of several species of Oxalis. The Oxalis selections commonly sold as shamrocks are grown more for foliage than for their flowers. Both green and purple foliage are popular, and some have quite striking variegated patterns. The shamrock’s dainty flowers vary from white to pink and from lavender to yellow, depending on the cultivar. Their flowers close at night […]
