March into the garden with these tips and tasks

Gardeners in Middle Tennessee (home of The Garden Bench) know that, in spite of what the calendar says, early spring has arrived. It’s almost March, and buds are swelling, bulbs are up and many are blooming, tips of favorite perennials are poking up through the mulch. And while we know that winter can – probably will – visit us again in a few days, we can get outdoors and enjoy the emergence of the new season with these early-spring tips and tasks.

Spanish bluebells emerging

Prepare new garden beds: Have the soil tested (check with your county’s Extension service to learn how). Remove grass and dig or till soil 8 to 10 inches deep and mix with soil amendments and organic matter to improve drainage.

Add a dose of fertilizer to perennials as soon as you see new growth. Keep it light; too much fertilizer may result in lanky growth.

Cut back liriope and other ornamental grasses. It’s easier now that it will be once new growth emerges.

If your fescue lawn looks a little skimpy, overseed early this month. Fescue grows best when the weather is still cool. It’s best to wait until early fall for a complete lawn renovation.

Plant lettuce and other cool-weather crops

Herb transplants that don’t mind cool weather — parsley, cilantro, sage, oregano – can go in the ground now. And of course you can also plant seeds and transplants of radishes, lettuce, spinach and other cool-season vegetables.

Clip dead stems from perennial herbs – thyme, sage, lavender, rosemary (if your rosemary survived; many Middle Tennessee gardeners’ rosemary plants succumbed to the cold this winter). Pruning those perennial herbs encourages vigorous new growth. Remove mulch or leaves that may be covering perennials in garden beds.

If you need to prune nandinas, flowering quince and other airy shrubs, don’t shear the shrubs. Reach in and remove about a third of the branches at ground level.

Give pansies a light dose of fertilizer as they continue to bloom through early spring.

When you cut daffodils and other early-spring flowers to bring inside, cut the stems at an angle and place them in water right away. Change the water in the vase daily to keep them fresh longer.

Coming up: Nashville Lawn and Garden Show

The annual Nashville Lawn and Garden Show is what signals the arrival of spring for many Middle Tennessee gardeners. This year’s show will be March 1 – 4 at The Fairgrounds Nashville. The all-indoors event includes live gardens from top landscape designers, displays, vendors, a floral gallery and an extensive lecture series. This year’s featured speaker is Brie Arthur, author of “The Foodscape Revolution,” who will present lectures on March 3 and 4. For my interview with Brie and more details on the show, see the story here at Tennessean.com, and in Friday’s Tennessean.

November garden tips & tasks

Summer’s over, and the winter holidays are approaching. It’s time to begin thinking about spring. Naturalist Deb Beazley, who leads classes in organic gardening at Warner Parks Nature Center in Nashville, says it’s good to begin planning for next year, even while this year’s garden is still on your mind.

fall leaves

Rake fall leaves from the lawn and use them as mulch.

Fall is a good time to begin to prepare the space for next year’s garden, provided the ground isn’t wet. “At least begin to kill off the grass,” she says. You can accomplish that by covering the parts of the ground you want to turn into garden with clear plastic, newspapers or mulch. If you prefer to use raised beds, build them now. “Get the soil in and get it acclimated. Now is a good time to fill it up and let it settle,” Beazley suggests

Seasoned gardeners can think about bedding down the garden for wintertime. But rather than let the soil lie fallow, she recommends putting it to work by sowing a winter cover crop, such as buckwheat, winter rye or clover. Plan to work it back into the ground with shallow tilling early next spring, which puts nitrogen back into the soil.

It’s also leaf-gathering time, and those leaves you rake up can provide a deep layer of mulch on garden beds in the winter. While you’re leaf gathering, set some aside for later, too; the leaves you rake off the lawn this fall will come in handy next summer, when you can again use them for mulch.

“Cover them in bags so they don’t decompose by the time you need them in June,” Beazley suggests.

Other garden tips and tasks to enjoy this month:

∙ If your landscape is blessed with large trees, leaf removal may be your biggest garden task this month. Fall leaves are a great addition to the compost.

∙ If the weather is mild, you can still plant cool-weather ornamentals early this month – colorful kale, ornamental cabbage, or pansies if you enjoy having flowers in the landscape in winter. Place transplants close together for best color impact, and firm the soil around them to keep freezing and thawing soil from pushing them out of the ground (a process called “heaving”). Add mulch for more winter protection.

∙ Plant spring-flowering bulbs. As a general rule, plant bulbs – pointed end up – at a depth about three times the width of the bulb.

∙ Fall is a good time to plant shrubs. Dig a wide hole that is only as deep as the shrub’s root ball, place the shrub in the hole and fill in the soil. Be sure to firm the soil around the shrub’s root ball, water well, and add several inches of mulch.

 

Daffodils may be too crowded to bloom

Our bed of daffodils has been growing for many years and has a lot of thick foliage, but just a few blooms. They should probably be divided. Can I dig them up and replant them now? 

Daff crowded Daffodil bulbs divide themselves every year or two, and the clumps begin to compete for food and space. This will affect their blooming – they’ll begin to produce fewer and fewer flowers.
So, indeed, after bulbs have been growing in the same place for many years, they may need to be dug up and divided. When the foliage turns yellow later this spring (but before it disappears completely), dig the bulbs, separate them, and replant them about 6 inches apart, 6 inches deep.
This is prime-time for daffodils in Middle Tennessee, and a little extra care and attention this time of year can improve your daffodil planting over time.


April in the garden: This could be the start of an especially satisfying – or challenging – spring. Check out the April Garden Calendar in The Tennessean and at Tennessean.com.


A wise gardener once said…
In fact, there have been many wise gardeners, and they’ve said plenty of wise things.
“To sit in the shade on a fine day, and look upon verdure, is the most perfect refreshment.” (Jane Austen, in her novel Mansfield Park)
gardenwisdomAuthor Barbara Burn has collected many such bits of truth in The Little Green Book of Gardening Wisdom, just out this spring from Skyhorse Publishing. If you keep a garden, it’s a book that’s likely to have you nodding in agreement as you flip through the chapters.
“I love spring anywhere, but if I could choose I would always greet it in a garden. – Ruth Stout, “How to Have a Green Thumb Without An Aching Back” (1955).
Burns says in the introduction that she was surprised to discover that so many people have said so many things about gardening that deserve to be collected. “I concluded that the subject of growing things was of far more universal interest that I had anticipated, and a great deal more uplifting than all the volumes devoted to war and political history,” she writes.
“To create a garden is to search for a better world. In our effort to improve on nature, we are guided by a vision of paradise. Whether the result is a horticultural masterpiece or only a modest vegetable patch, it is based on the expectation of a glorious future. This hope for the future is at the heart of all gardening.” – Marina Schinz, in Visions of Paradise (1985).
There is also practical advice, in quotes from well-known gardeners past and present.
“I feel that one of the secrets of good gardening in always to remove, ruthlessly, any plant one doesn’t like… Scrap what does not satisfy and replace it by something that will.” – Vita Sackville-West’s Garden Book (1968).
“To get the best results you must talk to your vegetables.” – Prince Charles, in a television interview in 1986.
This book of wise words is not intended to use as a how-to-garden manual. “But it will, I hope, give every reader a sense of comfort to know that we are not alone when we are down on our hands and knees fighting with weeds or planting a row of seeds that will one day bring us great pleasure.”
The Little Green Book of Gardening Wisdom is available at Skyhorse Publishing in hardcover ($16.95) and as an ebook.

Leave gladiolus in the ground?

We planted gladiolus in the ground and in containers this summer. I’ve heard they need to be dug up and stored over the winter. Really?

glads orange garden benchGladiolus are tender summer-flowering plants that grow from corms, and where you live will probably determine whether to dig them up or not. Here in Middle Tennessee (Zone 7a), the recommendation from the University of Tennessee Extension is to dig up and dry the corms after the foliage dies back and before a heavy frost, but the truth is, most gardeners I talk to here leave the corms in the ground and they usually survive.

In colder areas, they should be dug and stored. The Web site of the Purdue University Cooperative Extension Service (in Indiana) for example, says that gladiolus corms should be dug after frost. Dig the corms by loosening the soil so that you can pull the plant out of the ground. Shake off the loose soil and allow the corms to dry in the sun for a day or two. Cut the foliage off 1 – 2 inches above the corms and store them in a cool, dry place.

Plant the corms again after the soil has warmed up, in late April or May. By planting in two-week intervals between May and July, you can have a succession of blooms for several weeks beginning about mid-summer.

Thin those overgrown glads

QUESTION: I have a bed of gladiolus in my condo courtyard. The plants have grown so thick that they look crowded and messy, falling over each other. I know I need to thin them out, but when? And how?

glads redGladiolus grows from a tender corm, and in cold climates, garden experts suggest digging up the corms in the fall and storing them over the winter. In Middle Tennessee, I doubt that many gardeners go to the trouble. Winters here are just not that cold, and the glads pop up with no problem in the spring.

But you can still dig them up in the fall for the purpose of thinning them out. Whether you’re lifting them out for winter protection or for thinning, the University of Tennessee   Extension suggests digging them up on a bright, sunny day in the fall, after the foliage dies back but before a heavy frost. Cut the foliage flush with the corms and dry them outdoors during the day, but move them to a warmer, well-ventilated area to continue drying.

After a week or two, the old corms should separate from newly produced corms; gently pry them apart and discard the old one, along with any that are diseased or scarred. Dry them in a warm place for a few more days, and when they are cured, store them in a cool, well-ventilated area through the winter.

Next spring, put the corms back in the ground. You only get one flowering stem per corm, but you can stagger the planting over several weeks to have a succession of blooms – the Extension office suggests planting at two-week intervals, beginning in late April or May and ending no later than 60 days before the first frost to provide flowers from about mid-summer and into the fall. Plant corms 4 to 6 inches deep. Taller varieties may need to be staked as they grow to prevent the top-heavy flowers from toppling.
