Gardeners Should Prepare to Avoid Frost

Recent hot weather has perhaps lulled us into forgetting that fall is upon us. But, soon, that first frost shall arrive. For gardeners who are prepared, an early frost does not need to halt the gardening season. The first frost or two is often followed by several weeks of good garden-growing weather. Gardeners can take advantage of these extra gardening weeks by protecting their plants through early light frosts. Plants vary in their susceptibility to […]

Fall Comes Early This Year

Fall is such an appropriate name for the season — leaves are falling with or without changing color! And it seems to be getting an early start this year, as many landscape plants have started their annual ritual of changing colors and dropping leaves. 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 […]

Managing Vines on Trees, Tomato Pruning, Daylily Deadheading, and Yucca Removal

Q. I have a lot of vines that grew up my two trees. I noticed that one of my large trees is now dying. Would those vines kill them by taking all of the water from the bark? Also, I have a patio tomato plant that is big and doing great. Would it hurt the plant if I cut off a lot of the lower branches? Thank you. — Jerry Maquet A. In the southern […]

Feed Garden Soil With Cover Crops

Many gardeners have used cover crops to help keep soil from blowing away over winter. An added benefit of raising cover crops is that the foliage and root growth can be tilled under in late winter to help loosen heavy soils and improve overall soil structure and fertility. Also known as “green manure,” these cover crops can be especially valuable in preparing a new site for gardening or for rehabilitating a heavy or compacted site. […]

Pawpaw: The Midwest Banana?

Although the pawpaw is native to the eastern and central United States, it is a surprisingly well-kept secret. Those who do know this fruit are not likely to forget its delightful aroma and flavor. The pawpaw has been called the Hoosier Banana, but probably only by Hoosiers themselves. The same plant is also known as the Michigan Banana, Kentucky Banana and other regional favorites. Botanically, the plant is known as Asimina triloba. The tree can […]

Managing Lawn Rust and Adding Bold Perennial Colors

Q. Last year, I put in a new lawn. It’s doing well, except, recently, it began leaving a rust-colored powder on my shoes. Is that something that will affect the health of my turf? — Jason Burks, West Lafayette, Ind. A. The powder is actually millions of microscopic spores produced by a fungus called rust. There are several different rust fungi that cause rust. The most common one on Kentucky bluegrass, annual bluegrass, fescues and […]

Just Have to Transplant in Summer?

Today’s mobile society often lands gardeners in the predicament of moving away from their beloved gardens at a time of year that is less than ideal for transplanting. Devoted gardeners just hate the thought of leaving all of their beautiful flowers behind. Ideally, the time to move most perennials is either spring or early fall. The hot, generally dry weather of summer is about the worst time of year to move any plant. But, sometimes, […]

Revive Annual Flowers

It is not unusual for annual flowers, such as impatiens and petunias, to look a bit peaked about the middle of summer. For some plants, such as pansies, stock and snapdragons, stress from summer heat turns off the initiation of flowers. But most flowering annuals are fairly heat tolerant and can be revived with a little pinch of their stems and a sip of nutrients. Though for the most part, our temperatures haven’t been all […]
