  • July garden tips & tasks

    Make sure the trees and shrubs you planted in spring get plenty of water. The Nashville Tree Foundation advises that trees planted in the last three years should receive 10 gallons per week per inch of tree caliper. Water your trees slowly with a bucket, soaker hose, slow drip hose or watering bag.

    As tomato plants continue to grow and produce, keep the soil around the plants consistently moist. Inconsistent watering is the reason tomatoes develop cracks.

    Summer annuals and perennials such as daisies, glads, zinnias, sunflowers, cosmos and others make beautiful summer bouquets. Cut them early in the day when they’re at their freshest and put them in water in a vase right away. Change the water daily to keep them fresh longer.

    Pick summer squash and zucchini while they are still small and tender for best flavor.

    Watch for tobacco hornworms on tomato plants and Japanese beetles on just about everything else. Pluck the worms off the tomato plants and dispose of them. (If you see one with its back covered with white eggs, leave it; it is being parasitized by a tiny wasp.) Knock Japanese beetles off plants into a bucket of soapy water.

    Cut back the stems of mums once more, before they begin to form flowers. This allows them to delay flowering until fall.

    Lawn growth (and lawn mowing) may slow down as the heat increases. Continue to mow as needed, but don’t cut the grass too short. Provide about an inch of water if it doesn’t rain.

    Don’t forget about those hanging baskets and container gardens in the heat. If it doesn’t rain, you may need to water them daily during the hottest part of summer.

    Overgrown beds of bearded irises should be divided every three to five years. July is a good time for this task.

    You can plant a second crop of summer vegetables that grow quickly. Cucumber, bush beans and zucchini can usually produce a crop by fall if seeds are planted early in July.

    Coleus’ beauty is in the foliage, so when it begins to bloom, pinch off the flower spikes to encourage the plant to grow fuller and bushier.

    Take a daily walk around the garden to enjoy the scenery, but also to spot problems with weeds or bugs before they get out of hand.

Troy Marden’s garden wisdom — and a book giveaway!

Annabelle

‘Annabelle’ hydrangea is among the plants that garden expert Troy Marden recommends.

A friend invited me to a gathering whose guest was the popular Middle Tennessee-based author and garden designer Troy Marden not long ago. He was there to share his considerable knowledge and to talk about his new book, Plant This Instead!, which came out earlier this year. The subtitle is “Better Plant Choices: Prettier, Hardier, Blooms Longer, New Color, Less Work, Drought-Tolerant, Native.”
That’s a lot to cover, but let Troy explain: “It’s a book about making better, more informed choices.”
A book about native plants? “It’s a book about good plants. It’s not all about natives,” he said. “There are tips about how to be successful with new varieties. We don’t like plants that misbehave. This considers what their replacements in our landscape might be.”

What are some of those misbehavin’ garden choices?

“Take beebalm, for example,” Troy says. “You have to manage it.” Specifically, Monarda didyma – that hardy and resilient beebalm that you find everywhere — can be fabulous in bloom. “However, the same characteristics that make it tough and resilient also make it aggressive when it comes to planting it in the garden,” he writes in Plant This Instead!. “Beebalm, like its cousins peppermint and spearmint, has the ability to take over an enormous area of valuable garden real estate in a very short period of time.” It’s one of the plants he calls a “garden thug.”

Instead, consider the better-mannered wild bergamot, Monarda fistulosa, or take a look at Eastern beebalm, Monarda bradburiana, which has greater tolerance for drought and resistance to powdery mildew, and which grows in noninvasive clumps.

From garden thugs, the conversation shifted to what is meant – really – by the term “low maintenance” when you’re talking about a garden. In Troy’s world, gardening is not a low-maintenance endeavor.

“What you have to decide is, what does ‘low-maintenance’ mean to you?” he told us. “You have to think about how much you want to have and how much time you want to spend tending to it.”

Plant This book jacketAnd if your idea of a perfect landscape seems overwhelming, here is probably the best bit of wisdom Troy could pass along about growing and enjoying a garden: “Rather than having a huge garden that demands all your time and energy, do what you can in the way that you can do it to the best of your ability.”

Learn more about Troy at his website; catch Troy in person or on TV (he’s a popular and respected plantsman and speaker and one of the hosts on the Nashville Public Television show Volunteer Gardener), or read Plant This Instead!

  1. I love hydrangeas, and appreciate Troy Marden’s recommendation of the “Annabelle” hydrangea.

  2. like roses

  3. I love the peony.

  4. I recently bought a plant called “Josephs Coat”. I purchased it in Jackson, Tn after attending the Summer Celebration. I have it planted in a container with three other plants and I am really loving this plant. I need to do some research on this on because it was missing the handy dandy plant info tag. The container arrangement is doing well…. I am just taking it one plant at a time!

  5. I love Rhodos and the peony. Can´t choose which one is my favorite. Love them both 🙂

  6. I’m partial to peonies as well, and also gardenias. And this year in my containers I have the most beautiful begonias I’ve ever grown, so they’re my new favorite annual. As for Troy’s book, I particularly like those tags “blooms longer” and “less work!”

  7. Ironically, I adore bee balm. They were wonderful in my garden in the Hudson Valley because we owned an old farm and we had tons of space. They helped fill it with a sea of colorful blooms. Here, my bee balm suffered from mildew, so I pulled it out. I want to try Monarda Bradburiana – the substitute Troy mentioned and see how it does!

  8. I fell in love with rhododendrons when Dave and I moved into our first house. Someone had planted a rhodie in the hottest spot of the grounds and it looked a bit, well, dead. There were other REALLY dead bushes out there, too. I decided to try to save only the 3-foot rhodie and tucked it into a very narrow north-side yard near the backside of the HVAC unit. The next spring, I happened upon it just as it started to offer the most delicious lavender buds that opened into big white blooms with perfectly lavender centers. It was too big to move when we left, and I planted new white rhododendrons at the new house. Try as I may, I can’t duplicate that first one, but I keep trying.

  9. My favorite flower this summer is hollyhocks. A friend gave me seeds last year and I threw them on the ground. They are 9 to 10 feet tall and glorious! They remind me of my childhood.
