    GARDEN EVENTS IN MIDDLE TENNESSEE

    May 20: Master Gardeners of Davidson County Urban Gardening Festival, 9 a.m. - 4 p.m., Ellington Agricultural Center Demonstration Garden. Free admission. www.mgofdc.org; on Facebook at www.facebook.com/mgofdc.

    June 10: Middle Tennessee Daylily Society show and sale, Ellington Agricultural Center’s Ed Jones Auditorium, 440 Hogan Rd. in Nashville. Sale open at 10 a.m.; show opens to the public at 1 p.m. To learn more about the Middle Tennessee Daylily Society, visit www.middletndaylilysociety.org.

    It’s time to plant those tender herbs and vegetable transplants, such as basil, dill, tomatoes, green peppers, hot peppers, eggplant.

    If tomato transplants are already too tall and leggy, you can plant them on their sides and cover the long stems with soil. The stem tips will turn upward, and the buried stems will sprout roots.

    Sow seeds of bush beans and pole beans, cucumbers, sweet corn, melons, okra, field peas, pumpkin, squash and zucchini. Follow the directions on the seed package for planting depth and spacing. Vegetables grow best in full sun.

    Cut the faded blossoms of peonies. Fertilize the plants lightly in late spring or early summer.

    Remember the basics of watering: morning is best, so plants’ leaves have time to dry before evening. Lawns, perennial borders and annuals like to have 1 – 1½ inches of water per week.

    Many indoor plants enjoy a summer vacation outdoors. Give them a cool, shady spot in the yard, and don’t forget to water them.

    Prune thyme frequently so it will stay full and green in the center.

    Weeding is easiest after a rain. If the ground is too dry and you need to weed, soak the bed first with a hose or sprinkler.

    Whether they’re growing in the ground or in pots on the porch, pinch the tips of geraniums from time to time to encourage them to branch out and to produce more flowers. Geraniums in pots benefit from regular feeding with a water-soluble fertilizer.

    Remember that mulch can be a gardener’s best friend. Pine straw or composted leaves are good alternatives to hardwood mulch.

    Harvest herbs as they reach their peak. Dry small leaves on a screen, hang small bunches of long-stemmed herbs in a warm, dry room out of the sunlight.

    Plants growing outdoors in containers dry out quickly when it’s hot. Check them daily, and water as needed.

    Don’t go near hydrangeas with the pruning shears unless all you’re cutting is dead branches. If the bigleaf hydrangeas look like they’re not going to bloom, it could be that the buds were nipped in a late cold snap, or the plant was pruned too late last year.

    As the flowers of Shasta daisies begin to open and then to fade, keep them clipped off. This prolongs the blooming season of daisies (and most other annuals and perennials), and keeps the plants looking better, as well.

    Watch for aphids on shrubs and perennials. A strong blast of water from a hose will remove many of them, or spray with insecticidal soap.

Zinnias for summer – and a Book Giveaway!

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?

ZinniasYou’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.”

Leave a comment at the end of this post about your favorite May blooms – or just say “Count me in!” Respond by 6 p.m. Friday, May 15, 2015, and your name will go into a drawing to win one of two copies of Troy Marden’s Southern Gardener’s Handbook.

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. Master Gardeners of Davidson County is getting ready for its annual Urban Garden Festival on May 16.

  1. No contest here: I could name peonies or snowball bush, but my favorite of all flowers blooms in May — lilies of the valley! Love their sweet fragrance and the delicate little white bells on a slender stalk!

  2. I love so many May blooms: woodland phlox and old fashioned roses, iris, peonies, and annuals such as verbena, lantana and petunias. I love it all!

  3. Pawpaws exhibit my favorite May blooms. Although I currently experience this vicariously, as my pawpaw trees are still wee little twigs, the flowers are beautiful and bring the promise of delicious fruit!

  4. I love lilies of the valley too. Count me in!

  5. Count me in. I love seeing Troy on Volunteer Gardener.

  6. I have always loved zinnias. One of my all time favorites. Count me in!!!

  7. I love dirt and want to learn more about it. I need Troy’s book!

  8. I am new to Mid Tennessee from Chicago and struggle to know what new and exciting things I can grow here that I could not up there. Bad winter 2014 saddened me but I am told to be optimistic. Would love some reference from those that have the history of this beautiful new state.

  9. My dad grows a great line of irises across our extra lot, in front of his garden. Strangers stop to admire them!
