I love seeing zinnias in a summer garden, and want to plant them in my yard this year. Is it too late to grow them from seeds?
You’d get that great summer zinnia look a little sooner by planting bedding plants, if you can find them, but early May is not too late to plant zinnia seeds. In fact, they get off to a better start if you sow seeds after the soil has warmed, as they sprout and grow quickly.
Sow the seeds in a prepared garden bed (good garden soil in full sun) about ¼-inch deep. Keep the bed moist, and once they’re up, thin the plants to at least six inches apart. This is important to provide good air circulation around the plants; a bed planted too thickly may be more susceptible to powdery mildew when summer’s humidity sets in.
Then, just wait a few weeks for them to start blooming. Butterflies will love them, and you’ll be able to cut flowers for summer bouquets from the time they start blooming until frost knocks them down. The more you cut, the better and bushier the plants will be.
There are dozens of zinnia varieties, tall and short, and a range of colors. Most of the familiar forms are common zinnia, Zinnia elegans, but gardeners who wish to avoid the powdery mildew problem may want to try Z. angustifolia, or narrow-leaf zinnia, which grows in a mounded form. The flowers resemble miniature daisies, and the plant blooms from early summer to frost.
A fun fact that I found at the Rodale’s Organic Life website: when zinnias, which are native to Mexico, were introduced in Europe, the flowers were referred to as “everybody’s flower” because they were so common and easy to grow.
Book Giveaway! Southern Gardener’s Handbook by Troy Marden
If you ask Troy Marden about the best plants for a garden, he’ll most likely talk about soil.
“That may not be the answer you expected and it’s usually not the answer most people want to hear,” he says. “People want to plant pretty flowers, trees and shrubs.
“But if you don’t start with your soil – amend it, feed it, nurture it – the results will be lackluster.” That’s especially true here in the south, where we often try to coax a garden out of heavy, wet clay.
Troy is one of the Mid-state’s favorite go-to garden experts, so we listen to what he says. He’s passing along more of his garden knowledge in a new book, Southern Gardener’s Handbook, published this spring. Besides his thorough lesson on soil and how to make it better, he offers his ideas for best practices on watering, fertilizing, understanding microclimates, sun and shade, compost and “greener ways to garden.” This is followed by three hundred full-color plant profiles, organized under ten plant categories from annuals to vines.
“I wrote this guide as comprehensive, but approachable,” Troy says. “Interesting enough for the more seasoned gardener, but easy enough to understand for those who might be getting their hands dirty for the first time.”

Small space, big returns: It’s possible to grow edibles and ornamentals even if you don’t have a plot of soil that you can call a garden. In Saturday’s Tennessean, master gardener Mary Boyd discusses several ways to garden in small spaces.
