Fire blight is a disease that can infect apples, pears, and certain ornamental species including crabapples, cotoneaster, and mountain ash. Occasionally it may also appear on cherries, plums, Juneberry (also called Serviceberry or Saskatoon), and raspberry. This disease, caused by the bacteria Erwinia amylovora, can damage blossoms, fruit, leaves, shoots, and branches. If it is not controlled, fire blight may kill the entire tree or shrub. Infected tissue cannot be cured, but will need to be removed from the tree to prevent further spread.

Coleus have long been a great plant for gardens, generally grown as foliage plants that offer a huge diversity of foliage colors, and can be grown in a diversity of soils, in part shade to sun. In recognition of this important garden plant, the National Public Garden Bureau has declared 2015 the Year of the Coleus.
Fall is a busy time for farmers in the northern Great Plains, harvesting thousands of acres of corn and soybeans. Not too far away, in central and northern Wisconsin the harvest was in full swing too, but the crop they are harvesting is a small fruit called the cranberry. Wisconsin is the leading state in cranberry production, growing 60% of all of the cranberries consumed in the United States.
Poinsettias need bright light! They can actually probably handle full sun at this time of the year when the sun angle is low in the sky and we often have lots of cloudy weather. The important thing to remember is that if you want to keep your plant healthy, you need to give it enough light so that the green leaves can continue to photosynthesize and produce the carbohydrates that the plant needs to grow.
Even if it is freezing outside, we can still garden inside. One of my favorite groups of plants are the succulents and one of my favorite succulent plants is the aloe.
Chrysanthemums are the quintessential fall blooming plant that are sold in hundreds of stores of all kinds, all over the region. They are prized for their beautiful display of flowers that add so much color to our landscapes, decks and patios each autumn. They are a favorite of gardeners everywhere and have commonly become known as simply mums, which certainly has a nice homey sounding name. But not all mums are created equal! You need to shop carefully if you want plants that will look good this fall and also come back in future years and bloom before a hard freeze puts an end to their floral display in the fall.
Everyone can enjoy the natural beauty of flowers and ornamental plants with some simple recommendations.

Before she became an SDSU Extension Master Gardener, Arlene Brandt-Jenson's modest flower garden served to beautify her home's landscaping. Today, her garden has increased in size, beauty and it provides habitat for many butterflies, bees and other pollinator insects.
Swamp milkweed (Asclpeias incarnate) is native to the Great Plains, and is a great ornamental milkweed for your home garden. Don’t let the swamp milkweed name discourage you from trying this plant, you do not need a swamp to grow it, since it is a very adaptable plant. While it prefers average moisture conditions, it can tolerate periods of dry weather as well as some occasional standing water. It too is perennial but generally not as long-lived as butterfly weed.
