October “In The Grow”

Q. We’re novices to gardening but would like to grow statice and eucalyptus. We have lots of room for the plants. Our soil type is clayish. We live in Rising Sun, Ind. (Ohio County). When and how do we prepare the soil, location (sunny or shade), herbicides, pesticides, food (type and frequency of application), soil additives, etc.? Sheldon Boatright, Rising Sun, Ind. A.

Pumpkins May Need a Temporary Home

It seems that pumpkins often mature much earlier than we would like, and this year is probably even earlier than usual. The extremely warm growing season has brought the pumpkins on in a hurry. And unfortunately, the dry weather might contribute to an early end for the pumpkin plants, unless you’re able to irrigate on a regular basis. The conditions needed to store pumpkins until Halloween are pretty hard to find this time of year. […]

Bringing Houseplants Back Indoors

Many houseplants thrive during the long, bright summer days, especially when properly moved outdoors. But these plants may have some trouble adjusting to indoor conditions when colder weather strikes. Many of our common indoor plants are native to the tropical or subtropical climates and cannot tolerate cold temperatures. Houseplants should be brought back inside before the outdoor temperature drops to 55 F. If days are warm but night temperatures are cold, you might consider bringing […]

September “In The Grow”

Q. Several years ago, we were in Michigan to attend a national REMC convention and, somewhere along the way, I bought a ‘Caveman’s Club’ gourd. It grows up to a foot in length and has a bumpy round part with a long neck. It is somewhat, but not exactly, like the dipper gourd. I ordered seeds of an ornamental mixed variety, but there wasn’t any seed like I wanted. As I remember, the seed’s shape […]

The Fall Vegetable Garden

Fall is an excellent time to grow many vegetable crops in Indiana when the gardener can take advantage of cooler temperatures and more plentiful moisture. Many spring-planted crops, such as radishes, lettuce and spinach, tend to bolt (produce seed) and become bitter in response to long, hot summer days. Fall gardening helps extend your gardening season so that you can continue to harvest produce after earlier crops have faded. Some vegetables, such as broccoli, cauliflower […]

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 […]

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 […]

Gardeners – Start Your Sprinklers

Hot and dry may be just fine for picnics, ball games, and other outdoor activities. But for gardeners, hot and dry means its time to drag out the hoses and sprinklers. Most gardeners are accustomed to watering flower beds and vegetable gardens. These plants require approximately 1 to 1 1/2 inches of water per week to maintain healthy flowers, foliage, roots, and fruits. In times of drought, established plants may tolerate 10-14 days between waterings […]

July “In The Grow”

Q: I would like to plant a red rose bush this year, but I don’t know where to start. There is lots of red clay at my house, yet I figure a few bags of topsoil will take care of that problem. When should I plant them? — Ray Padgett, via e-mail. A: Bare-root roses must be planted in the spring, but container-grown roses can be planted any time during the growing season. Dig the […]

Poison Ivy : A Variable Pest

Rosie Lerner, Purdue Consumer Horticulture Specialist Released 17 June 1999 Perhaps you’ve heard of the old saying? “Leaves of three, let it be?” Excellent advice for those who are sensitive to the poison ivy plant. A Perplexing Plant Poison ivy, Toxicodendron radicans, is generally a woody plant with three leaflets; that is, each individual leaf is subdivided into three leaf-like structures. But that’s where the generalizing ends. Poison ivy can be a vine growing up […]
