Free Plants Every Spring

A New Year with New Beginnings

free plants every springWe’ve been having a warm spell this February, and I am encouraged by the new sprouts emerging from the garden cloche cuttings I stuck in the ground last fall. I buried some stems of my favorite shrubs as deeply as possible into moist soil and covered them with large upside-down jars for the winter. To hedge my bets, I surrounded the glass jars with bubble wrap to keep the stems extra warm and toasty. Then I pulled pine straw around the bottom to keep out cold winds. When the weather warms in the spring, I pull off the jars and, voila! New plants.

free plants every springIt’s easy to build a collection of garden cloche jars. The traditional bell jars are quite expensive, but I visit thrift stores and yards sales for fifty-cent versions. Old floral containers work just fine. The handy handle topper is missing, but I can manage without it. The bigger the jars, the better.

The jars act like tiny greenhouses, holding in moisture and sunlight and warmth. Some shrub species accept this propagation method very willingly—Hydrangeas and Roses, especially. Can you have too many Hydrangeas and Roses? I don’t think so!

Amazing Shrub for Heavy Shade

Aucuba is Not Perfect, but Nobody’s Perfect

shrub for heavy shade, shade plant, shade plantsAucuba can be grown from hardiness Zones 7a to 9B. The people who live in those zones, south of the Mason-Dixon line and along the coastal perimeter of the U.S., either love it or hate it. I’ve seen it sold as a houseplant, probably because of its glossy, leathery, colorful leaves. I love it.

I’ve never noticed the flowers, and the large red fruits are only on female plants, rarely available in bread-and-butter nurseries. Most cultivars grow about four feet tall. The red berries clash with the variegated leaves, but they look striking on the all-green cultivars. The leaves are amazing. The greens are deep and dark and the variegated varieties have screaming blobs of chartreuse and yellow.

There are a few reasons people hate it. A lot of southerners remember their mothers or grandmothers using ‘Gold Dust’ in flower arrangements, rooting the ugly, thick stems in water on a sunny windowsill, and giving it away to friends. It was very popular in the sixties, but people are tired of it now. I’m not. Shrubs go in and out of fashion, and this one has not seen the “old is new again” stage in the nursery industry. Maybe five years from now.

When it gets diseased, it looks like something out of a horror flick. Stems and entire branches go completely black—black, mind you—if they contract one of the rots that attack it in poorly drained, nematode-infested soil. Other manifestations of their problems include necrosis, fungal growth, wilting, and necrotic spotting. Just the names sound disgusting!

If you plant it slightly above grade in good soil, keep mulch away from the roots, and cut out problem branches back to healthy tissue with clean clippers, the problems go away. Those fixes are quick and easy and don’t involve chemicals. Anything that doesn’t involve regular spraying is okay by me.

February—Time to Prune

Winter Prune before the Forsythias Bloom

dormant winter pruningThere will be a glorious false spring sometime after Christmas and before Valentine’s Day, each year if you are lucky. When it comes, get out there and prune away! Dormant winter pruning should be done after woody plants have gone completely dormant and before new buds begin to swell.

When major pruning of broadleaf evergreen shrubs is required, sometimes it is easier to shear first (as in the photo above) and then selectively remove the remaining limbs as needed, using the deep cut hand-pruning method. For commercial properties, severe shearing of no more than one-third of the branch tips in winter can be a good way to keep low parking lot hedges low, allowing visual scanning of the property for safety.

Prune Junipers to keep them dense by lifting each long limb individually and cutting back to some remaining green growth. Any more, and you will end up with nothing but a bare stump.

Of course, you need to wait to prune most flowering shrubs until after they bloom, unless you are trying to rejuvenate the entire shrub and can do without blooms for the year.  It is tempting to prune everything while shears are in hand, but resist the temptation. Plants with pithy centers or hollow stems will suffer as late winter rains might rot the stumps.

It is probably not a good idea to prune if you expect a severe cold snap right away. It takes some plants, especially small fruit trees, a while to re-acclimate to cold after major pruning. The exposure of moist, fresh stumps that haven’t hardened off for a few days could do harm to the plants.

Plan on a nice warm spell sometime in late January or early February, and keep your clippers sharpened and ready!

Looking for the Best Winter Blooms?

Nothing Beats Pieris for Cold Weather Flowers

winter flowers, winter landscape, winter bloomsOne of my favorite plants shines when all the others are dormant—Pieris. It is also called Andromeda, but Pieris is easier to say. It has some wonderful features. It is evergreen with beautiful, shiny leaves. It is tall and narrow, but not too tall—one of the few plants that actually fits long-term in the tight places near entrance steps, flanking doorways, without spilling out on to the sidewalk and blocking the way. In early spring the new foliage is bright red. In fall, the flower buds are crimson. Not only that, this polite little plant blooms its heart out with large clusters of pinkish white bells in January!

The Callaway Gardens Vegetable Garden

The Victory Garden is Defeated

victory garden south, callaway vegetable gardenIt was sad to see the recent closing of one of the greatest gardening displays in the United States. The Callaway Gardens Vegetable Garden showcase is no more, as a result of shifting priorities away from horticulture. There were not enough visitors. This wonderful gardens simply could not last during the repeated recessions of the last couple of decades. The venue displayed home gardening on a grand scale.

The John A. Sibley Horticultural Center

Sadly Missed

botanical gardens, horticulture, horticultural centerSwiftly and silently, the powers that be decided to close one of the greatest horticultural displays in the United States. Sibley Center is no more. Callaway Gardens has shifted priorities from horticulture and floral beauty to resort and golf. That is the way with wonderful gardens. They simply cannot last during prolonged recessions. I am so happy I was able to spend a lot of time there when my children were young, so they could see ornamental horticulture done on a grand scale.

Sibley opened in 1984 as part of an expansion inside Callaway Gardens in Pine Mountain, GA. It was designed by Robert E. Marvin and Associates to be a showcase of energy-efficient blending of indoors and out, with folding walls that could be open during warm weather and could close to protect vegetation from extreme cold. 

About Shrubs

professional plant advice, sage leafI am a plant nerd. My fascination started at summer camps and state parks, touring woodland wildflower trails with experts on edible natives and shady stream ephemerals. In college I was motivated to study landscape architecture after being inspired by Mary Wharton, my professor and author of A Guide to the Wildflowers & Ferns of Kentucky and Trees & Shrubs of Kentucky, books I still refer to today. During my landscape architecture internship, Michael Dirr’s Manual of Woody Landscape Plants: Their Identification, Ornamental Characteristics, Culture, Propagation and Uses was the essential reference in the landscape industry, and I read it cover to cover. It was such a privilege to hear so many great plant experts speak, and even better to visit their home gardens.

My background is in landscape architecture with a strong emphasis on horticulture. I did a lot of industrial campus plans and municipal work before being hired to review landscape design plans for a state department of transportation, and I worked, early in my career, on large-scale planting and irrigation plans. I did lots of residential work, too. I got to know the green industry and gained practical experience in how to keep plants alive and maintain them. You get to know plant species after specifying several hundred of them on a single site!

I reviewed thousands of landscape plans, and also provided technical advice for anything related to landscapes, wrote contract specifications for planting and grassing, wrote maintenance specifications and work plans, and created statewide policies for roadside landscape projects and permits. I also helped create a statewide landscape grant program and vegetation management permit policy which provided ongoing funding for the program.

It has been great fun doing all this, but what good is it for a single person? I want to share the practical and experiential advice I learned with you. It takes a long time to become a professional landscape design and plant expert, because so much of what is realized comes from hearing the stories and experiences of in-the-field landscape industry professionals. I never read that the Red Maple species are much stronger in storms than its cultivars. I learned that while riding in a truck to a construction site with a seasoned landscape contractor. An owner of an industrial landscape maintenance company explained to me how sensitive Sweet Gums are to root disturbance. A garden club lady taught me not to prune back perennials with hollow stems in the fall to avoid rain rotting out the root system before spring growth could begin. Being a master gardener volunteer for many years gave me a wealth of information from agriculture extension, too.

What do I want to tell you about shrubs and ornamental plants?

• You have thousands of choices. Choose wisely and you will avoid lots of pruning later.

• Flowers provide color, but you can achieve longer-lasting interest and a more sophisticated landscape composition by using foliage color and textural contrast.

• You can use the tips and guidance on this web site to use plants to their fullest potential and create some amazing landscapes. It may seem simple to pick up a truck-load of container plants, walk around on a site with shovel in hand, and plant them.

The devil is in the details, though!

I want to share as much as I can with you about what I’ve learned over the years, but you can find detailed information in my Advanced Guide to Shrubs eBook, coming soon. I would love to hear your comments and about your roadside enhancement stories and experiences, too.

Professional Pruning Techniques

Pruning Creates or Maintains a Shrub’s Natural Form

professional pruning techniquesTopiary is a delight. Controlling nature is an impressive show of power. Too much power corrupts, according to Lord Acton. I will paraphrase his famous words—Put down your electric shears.

Good pruning is like a good haircut. There are times when a dramatic, Avant guard, blunt cut is exciting, but most trimming should look natural. The best way to prune is to clip away anything that challenges a plant’s natural shape, and hide the cut deep within the remaining foliage. Limit the tortured, manipulated geometric shapes to theme parks and special display areas. Pruning shrubs into unnatural shapes brings decline, cuts off potential blooms, and is inappropriate for every setting (except a formal parterre garden).

Avoid the temptation to create green balls and trapezoids out of foundation evergreens. It’s tacky. I’ll leave it at that. Professional landscape designers create maintenance specifications that prohibit the use of electric shears for this very reason. Look at the excellent example of specialty shearing in the photograph. Everything tapers to a wider base, so sunlight can reach all the branches. This topiary menagerie has lasting quality because the professional pruning crew understands plant material.

A Midsummer's Floral Beauty

The Last Burst of Color before the Dog Days

summer bouquet, cutting back flowers in mid-summerThere can be two floral seasons in the summer if you put in some extra effort. The first typically ends the first week in July, just before the dog days of summer begin. If you can brave the heat and humidity to do a few maintenance tasks in the next couple of weeks, it will pay off with a second flush of color and floriferous-ness in late summer.

Step One—Cut back any spent blooms and any flowers that have peaked right away. Deadheading can wake up perennials by fooling them into thinking their primary directive for reproduction has not yet been completed. Allowing the older flower heads to go to seed will send plants into a lazy decline and the foliage will begin to suffer from pest damage while the stems will elongate and flop to the ground. Interrupt the circle of life by removing both the petals and the developing seed pods. Be thorough. Leaving behind any flower heads and seed pods will keep the plants complacent, thinking their job of reproducing a new generation is done.

Step two—Rejuvenate large masses of flowers in a wholesale manner by cutting back the entire plant by about one-fourth the total height. This will scare out fresh growth and result in densely branched stems ready to set new blooms. Shearing back herbaceous plants removes damaged foliage that harbors insects and disease.

Step three—Forget step two. Carefully trim each individual stem to get a more refined, aesthetic look. Giving them a haircut helps the appearance of the garden, and the results of the cut-back will be directly related to the care with which you wield your clippers.

There are a lot of plants that benefit from this tough love. Shrub Roses, Purple Coneflowers, Lobelias, Chrysanthemums, Geraniums, Yarrow, Baptisia, Salvias, Daisies, Butterfly Bush, Fennel, Cut and Come Again Zinnias, and Marigolds. Other plants won’t be fooled. Black-eyed Susans, Pennstemons, Iris, and Daylilies bloom once, and that’s it. They’re done for the season. Their charm is their fleeting nature.

You need to perform this cut back to keep your landscape looking manicured and refined. By late July, spending time outdoors for very long is too hot and too muggy for comfort, so take advantage of cool evenings and breezy days. It may seem wasteful to remove some blooms at their peak, but you can bring them inside for arrangements and enjoy them at close range in air-conditioned bliss.
