Coneflowers for Late Season Color

If your perennials are looking a bit peaked this time of year, coneflowers may be just what the plant doctor ordered! The name coneflower actually refers to several different species of plants, but all have a similar type of flower structure. The flowers are in clusters that form a “head,” just like a sunflower or daisy type flower. Each of what appears to be a petal is actually an entire flower. Purple coneflower, known botanically…Read more about Coneflowers for Late Season Color[Read More]

August “In The Grow”

Q. We have moles all over our yard. I’ve tried mole beans, match heads, even moth Balls. Nothing works. We can’t walk in our yard without sinking down into a tunnel. Linda Bridges, Columbus, Ind. A. Moles eat earthworms, beetle grubs, ants and other animals that live in the soil. They generally do not eat,bulbs or the roots of plants. Still, the runways can damage our garden plants by exposing the roots to air and…Read more about August “In The Grow”[Read More]

July “In The Grow”

Dig the…Read more about July “In The Grow”[Read More]

May “In The Grow”

Q. Last season, I spread about 6 inches of hardwood sawdust on my pumpkin, squash and gourd garden to control weeds. The sawdust is still there and will act as a mulch for this season also. By using the sawdust, do I need to add any nutrients to my soil this season? If so, what should I add? – Myrna Sowers, Crawfordsville, Ind. A. Uncomposted sawdust ties up the available nitrogen in the soil, so…Read more about May “In The Grow”[Read More]

April “In The Grow”

Q. I’ve been out in the backyard giving myself a backache chopping down ornamental grasses. We love them 363 days a year; every day except for the two that we spend chopping them down and getting rid of the debris! Any thoughts? – Amy Raley, West Lafayette, Ind. A. We buzz down our ornamental grasses with electric hedge shears and a chain saw. The task goes by quickly! We leave the dried grasses in place…Read more about April “In The Grow”[Read More]

February “In The Grow”

Q. I am wondering what happened to my tomato plants this past year. Early in the season, they started getting yellow leaves at the base of the plant. Then, the leaves dried up; the complete plant almost turned that way. I have them caged, and they grew way above the cages. The tomatoes seemed to be good, but the plants were terrible. Hope you have an answer. – Mrs. Otis Rupright A. Fusarium and Verticillium…Read more about February “In The Grow”[Read More]

January “In The Grow”

Due to the wonders of technology, I received eight or nine questions in a less than timely fashion.

Throw some mulch on them, and I’ll answer the question in more detail soon! Sorry about the delay. Q. Are there any…Read more about January “In The Grow”[Read More]

Mild Weather Brings Up The Bulbs

Are your bulbs bursting? The recent warm spell may just stick around long enough to trick your bulbs–and perhaps a few other plants–into thinking it’s spring. This is the time of year when we normally expect temperatures to be cold enough to signal the hardening-off period to plants. And until quite recently, we were cold enough to start that process. Now, as the temperatures have been in the 50s and 60s for a while, some…Read more about Mild Weather Brings Up The Bulbs[Read More]

December “In The Grow”

It seems Indiana gardeners were spending their time preparing for the holidays rather than reflecting on recent garden woes. That means I get a month off! Here are some often-asked questions that I have run before. Q. I didn’t get my spring bulbs planted this fall. Is it too late? A. Your best bet is to plant them as soon as possible. If the soil is not frozen, plant them immediately. When the ground freezes, mulch the…Read more about December “In The Grow”[Read More]
