December “In The Grow”

Q. I gathered some bittersweet branches last fall. These are the decorative red berries gathered in the fall for winter arrangements in the home. I have saved some well-developed seed but can’t get them to grow. I stored some in the freezer for a time, yet neither did they sprout. I’m wondering if they must pass through a bird’s digestive process to sprout. The seed appears to be encased in a thick shell. If so, […]

The Vanilla Orchid

Although much of the vanilla used for flavoring and fragrance today is produced synthetically, natural vanilla comes from the seed pod of an orchid plant. Vanilla planifolia is a vigorous, vining orchid that can reach up to 300 feet in its native tropical American environment. The vine produces greenish-yellow flowers that must be hand-pollinated outside of its native habitat to ensure good fruit set. The pods grow to about 6-9 inches long and are harvested […]

November “In The Grow”

Dig Those Sweet Potatoes

Although some folks may be sad to see fall coming a bit early this year, many gardeners are looking forward to harvesting their sweet potato treasures. Sweet potatoes are warm-season plants that are very sensitive to cold temperatures. The tuberous roots should be harvested by the time frost kills the vines or soon thereafter. Sweet potato roots continue to grow until frost kills the vines. Roots can be left in the ground for a short […]

October “In The Grow”

Q. What do I focus on now in my flower gardens? Should I be pruning things before winter? Do I need to clean up the perennials and maybe put down some mulch? What do I do to get a couple of rose bushes ready for winter? – Mike Wadsworth West Lafayette, Ind. A. Autumn frosts will soon take their toll on the garden. Head outside with a pair of pruners and begin cutting perennials off […]

Lesser Known Perennials Extend Spring Color Show

Tulips, daffodils, and crocus are stars of spring in Midwestern flower gardens. But there’s an array of supporting players that can add variety to your spring bulb show. Winter Aconite (Eranthis hyemalis) brings a splash of yellow, buttercup-type blooms on dwarf, 3-6-inch plants. Winter aconite is appropriately named for its early arrival, often pushing its blossoms through a cover of snow in February, though sometimes as early as January and as late as March. Plants […]

September “In The Grow”

Q. I have a weed in my garden that I can’t get rid of. It lies close to the ground and spreads. It has small green leaves that are thick and feel like rubber. Is there anything you can tell me to help me get rid of it? Thank you. – Sheila Denton, via e-mail A. It could be a number of weeds but sounds most like purslane. Purslane thrives in hot, dry weather. The […]

Pin Oak Looking Yellow?

Pin oak trees can be a beautiful asset to the landscape. Their pyramidal form, pendulous lower branches and reddish or bronze fall color are striking. Unfortunately, most pin oaks planted in the Midwest are plagued by a yellowing of the leaves known as chlorosis. Other landscape plants are also susceptible to chlorosis, including rhododendrons, river birch, holly and sweet gum. Chlorosis gets its name from the lack of chlorophyll, the pigment responsible for healthy plants’ […]
