Cloches

Back in the early ages of gardening, someone realized covering a plant could protect it from frost and wind chill, preserving blooms and protecting foliage from the ravages of ice crystals and dropping temperatures. In Victorian gardens and parlors, dome-shaped glass covers protected many tender and treasured plants from the nip of winter’s chill. Because of the resemblance to a close-fitting, bell-shaped woman’s hat, these protective devices were called cloches, the French word for hats. You’ve probably seen them over a plant in someone’s garden or greenhouse. Today, in addition to protecting plants and extending the growing season, they provide a touch of whimsy and romance for an elegant garden, terrarium or greenhouse.

Our gift store offers several sizes, materials and styles of cloches for garden use. The clear glass bell-shaped cloches are also popular for in-house decorating. Placed over a miniature orchid to enhance its growing environment or protecting a treasured arrangement, these gardening items show your trend setting and eclectic gardening style. They are ideal for specimen plants, or may be used to showcase a vintage vase, whimsical fairy garden, lush succulent arrangement or favorite potted plant. Even indoors, they provide protection to regulate the humidity and temperature near a plant, eliminating damaging drafts and helping keep delicate, temperamental plants happy.

Although the original cloches protected only one plant, the “cloche concept” now effectively extends the outdoor growing season for row crops. Modern technology and new materials make it easy to continue growing even after the temperatures drop. Hoops, tents and row covers protect late crops from frost and wind, extending the season and ensuring later harvests for the full richness of the fruits, vegetables, herbs and flowers that need just a bit of extra time to mature. Whether you hope to sell late season crops and want to improve your profit margin or would prefer a later harvest for extra canning and preservation, these tools can increase your season and improve your yields.

We have a large selection of protective materials including frost protection blankets, plastic row covers and curved hoops to hold the cloth above the plants without damaging produce or bruising leaves. Furthermore, if you want the growing season to never end at all, you can consider cold frames and miniature greenhouses that can keep your green thumb bright and active even on the coldest days. Come on in to see our complete selection, and keep on growing.

Entrance Way Evergreens

Cool and classic or chic and contemporary, no matter what your style, you’ll always be proud of an entrance flanked with beautiful containers highlighting just-right evergreens. In this case, “evergreen” doesn’t necessarily mean a conifer, either – many other shrubs remain green in the winter and can be beautiful showpieces welcoming guests to your home.

Planting Your Container

Entrance way evergreens are generally planted in containers and frame a doorway, walkway or arch. If you truly want your evergreens to take center stage, opt for more understated, neutral containers, but select shapes that match the architecture of your home. You can opt for a boldly colored container, but take care that the container’s decorations won’t overwhelm your evergreens.

You will want to use high quality potting soil for the container to provide adequate nutrition for your evergreens to thrive. Also pay careful attention to the moisture levels, watering the plants appropriately – containers often need more frequent watering than plants in your landscape. You can rotate the containers regularly to help the plants get even sun exposure, and regular fertilizing will help keep them healthy.

If you’re not sure how to plant a container, try this simple formula: “Use a thriller, filler and spiller.” Thriller refers to the tallest or showiest plant, the one that immediately catches the eye. The fillers are the plants surrounding the thriller that add more structure and bulk to the arrangement, filling in empty spaces. The spillers are plants to grow over, and soften, the edge of the container, giving it a more natural, organic look.

Here’s a listing of “thriller” plants to consider for your door decor. We can make recommendations of dwarf cultivars of many of these plants. Dwarfs will take longer to out-grow their container. Happy potting!

Accents for Your Entrance Evergreens

In addition to welcoming your visitors with a beautiful entrance, it’s easy to entertain them and show your style when you accessorize your evergreens. Festively dress your plants to coordinate with seasons or holidays. Fun and creative options include…

Spring: Small bunnies, silk spring blooms such as daffodils, pastel Easter eggs
Summer: Patriotic flags or ribbons for Memorial Day and the Fourth of July
Fall: Scarecrows, pumpkins, Indian corn, Halloween decorations
Winter: Holly sprigs, tiny twinkling lights, beaded garlands, snowflake ornaments

You can also personalize your entrance evergreens for birthdays, anniversaries or to showcase your favorite teams, colleges, hobbies and more. All are easy to do, fun, and affordable, and make your entrance truly eye-catching.

Redbud Revelry

Gardeners love the Eastern redbud tree (Cercis canadensis). Native to North America, these hardy, slow-growing, small trees richly deserve their places front and center in the landscape. They flower very early in the spring (as early as April), provide beautiful fall color, remain reasonably small, are low maintenance and create quite a display when planted in groupings or as a single specimen. They even grow well in parking lots, sidewalk strips and in containers, making them ultimately versatile for all types of landscaping plans. What else could you ask for?

New and Exciting Redbud Varieties

As if the classic eastern redbud wasn’t beautiful enough, there are always new varieties that give these stunning trees even more charm and character. Which one will be the centerpiece of your landscape?

Recent introductions include ‘Lavender Twist’, which grows in an elegant weeping form, and the compact ‘Ace of Hearts’, which excels in a small garden or container as a blooming, dome-shaped, focal point. ‘Alba’ flowers in pure white and ‘Appalachian Red’ blooms with deep burgundy pink flowers. The leaves of ‘Hearts of Gold’ open red in the spring and slowly change to gold.

‘Rising Sun’ redbud, another new introduction, stops most people in their tracks. In spring, before leaves appear, lavender-pink pea-like flowers cover the trunk and branches. The show really starts when the leaves open and the heart-shaped, deep-apricot colored leaves transition through orange, yellow and gold to lime-green with all colors showing at the same time. In fall, the tree shimmers in shades of gold. Amazing!

Growing Your Redbud

No matter which type of redbud you choose, you’ll want to take good care of it to be sure it reaches its full beauty. First, be sure to plant your redbud in an area where it can stretch to its full size and show off the unique branching growth habit. You will also want to choose a position where the redbud won’t be crowded or overshadowed by other plants. These trees prefer at least four hours of direct, unfiltered sunlight each day, so full or partial sun positioning is best. These are hardy trees and grow well in most soil types, but adding organic material to the soil and mulching around the tree is always a wise idea to protect and nurture it.

Whether planted as a specimen, en masse, or in a container, we’re sure you’ll agree these little trees deserve consideration for a special place in your garden.

Pruners for the Lefties

Have you wondered why left-handed gardeners have difficulty using “regular” pruners? It’s because of the way the thumb and index finger have to push together to make the cut. It’s hard to control it for detailed work plus incorrect pruners often cause bruises and painful calluses to form.

Fortunately, there is a solution – pruners specially designed for left-handed use. The correct pruners, with the left blade on top, allow the leftie to see what they’re cutting and enjoy pruning. Come on in to check out which of these wonder-tools fits the best.

FELCO

Felco hand tools originated more than 70 years ago when Felix Flisch patented his first hand pruner, the Felco 1. The company’s three core values, ergonomics, interchangeability and durability, haven’t changed and even today, all their products incorporate these values. We carry two left-handed styles of Felco pruners.

Felco 9: This is the left-handed version of Felco 8, one of the most popular hand pruners ever. Recommended for up to 1″ cutting capacity, these bypass pruners have forged aluminum handles and hardened steel blades with a screw-mounted anvil blade. They include a lifetime guarantee. The efficient design includes a blade with a wire-cutting notch and a sap groove. The blades have removable dowel pins to allow easy maintenance and replacement. The micrometric adjustment system, using the included adjustment key, promises precision cuts and maximized user comfort.
Felco 10: This bypass pruner is the top of the line left-handed version of the Felco 7. Designed for the professional gardener (but enjoyed by all), this pruner requires 30 percent less effort, thereby reducing hand fatigue, tendonitis and carpal tunnel syndrome with its unique rotating handle. The narrow, pointed blade design facilitates close-in pruning. Like the Felco 9, an adjustment key is also included. Also recommended for 1″ diameter cuts.

Replacement parts are available for both styles along with holsters and blade sharpeners.

Bahco

This company, established in 1862, produces very fine gardening tools in addition to their industrial lineup. Although they look a little different, the workmanship and ergonomic design make them among the favorite of garden tools. This company uses the term “Secateurs” as hand pruners and designates the levels as professional or expert.

PX-M2-L: This is a left-handed version of the popular PX-M2 bypass model. The composite materials in the handle with an upper section of soft rubber act as a shock absorber. The ergonomic styling and vertical and lateral inclinations of the cutting head allow the wrist to remain straight when cutting. This reduces fatigue and increases comfort and performance. All parts are replaceable.
PXR-M2-L: This pruner is the left-handed version of the heavier bypass PXR model designed for frequent professional use. Home gardeners also love them! A rotating handle increases performance and comfort. All parts are replaceable.
PG-03-L: This tool is the left-handed version of the home gardener (expert) hand pruner. This model is available in two hand sizes, small and large, and in two pruning widths for 1/2″ or 3/4″ cuts. Fiberglass reinforces the plastic handles and Xylan® coats the blades to reduce friction and protect from rust. As a convenience, it has a one-hand locking mechanism.

Holsters and blade sharpeners are also available.

Corona and The Gardener’s Friend

The Corona BP6340 has aluminum handles and hook with replaceable blades and springs. The steel blades of high carbon steel and the ergonomically angled head result in close, clean and healthier cuts. With less stress to the wrist, it easily cuts up to 1″ branches.

The Gardener’s Friend Ratchet Hand Pruners are designed for gardeners with small hands, or hands weakened by arthritis, carpal tunnel syndrome or tendonitis. The unique ratcheting action easily cuts branches to 1″ thick with less hand strain.

Of course, we have an excellent selection of other specialized hand pruners in our tool department. Whether you are buying for a child, a delicate hand or a large-handed gardener, we have the proper sized tools to reduce strain and make gardening easier and more enjoyable for all.

Versatile Euonymus

What are your garden’s trouble spots? Do you need an evergreen hedge? A tall anchor plant at the back of a deep garden bed? How about an interesting groundcover? Perhaps your garden needs a medium-sized transition plant. Try a euonymus! This versatile plant does it all, and whatever your landscape needs, this family of plants probably includes your solution. Some are deciduous while others are evergreen, but all are easy to grow and adapt well to a variety of environments.

About Euonymus

With more than 175 varieties of Euonymus available, there is sure to be one to meet your landscaping needs and climate conditions. Evergreen types tend to prefer somewhat sheltered locations, while deciduous euonymus will thrive in full or part sun. Watering should be regular, with more frequent watering (1-2 times per week) in very dry conditions. Well-drained soil is best to prevent root-rot and while richer soil is ideal, euonymus can adapt to nearly any soil type. Pruning can help keep these shrubs compact and neat, and if left unchecked they may outgrow spaces and variegated leaves could revert to plain colors.

Euonymus Varieties in Autumn

In the fall, the burning bright colors of a deciduous euonymus are unmistakable and add rich autumn foliage to the landscape. The strawberry bush (E. americanus) burns bright yellow with scarlet red fruits with orange seeds. The spindle tree, (E. europaeus) has more red in its fall color and the berries are pink or red with white seeds. Probably one of the best known is the Winged Euonymus (E. alatus), often used as a deciduous screen, with unique “winged” twigs and bright red fall color. Choose from a number of different varieties with unique colors and varying mature heights.

The many members of E. japonicus provide solutions for evergreen hedges, edging plants and intermediate-sized shrubs. They range from 1-12′ tall. Some are green, while others have variegated yellow or silver leaf edges. Popular ‘Green Spire’ grows to 7′ tall but at only 1-2′ wide, it creates a narrow and easily maintained taller hedge ideal for screens and privacy. ‘Silver Princess’ grows only 3′ high and wide creates a beautiful silver-tinged border or is a great option for terraces or small bed areas.

For groundcovers, check out the prostrate varieties of E. fortunei such as ‘Coloratus’ (Purple-Leaf Winter Creeper) which turns dark purple in the fall or ‘Wolong Ghost’ with dark green leaves with white veins. There is even a dwarf groundcover, E. fortunei ‘Minimus’ which grows less than 6″ high!

Remember, many of these euonymus varieties add autumn beauty to your garden, so this is an excellent time to see them at their peak and choose which of these unique and stunning plants should be part of your landscape.

Bulbs: Increasing Your Yield

When you visit our garden center, you’ll find an incredible variety of autumn “bulbs.” Although they may look strange at this time of year, these “ugly ducklings” will become beautiful swans in your spring garden. It’s hard to imagine how these odd lumps can grow underground and become so gorgeous, but if you plant them now you will enjoy an incredible floral display next spring and summer.

How Bulbs Grow and Multiply

Did you know many bulbs will increase in quantity over time? Most gardeners simply divide their bulbs after a few years and move them to other parts of the garden or give extras away to friends. Dividing your yield is easy when you identify what type of bulb you are dealing with.

There are five distinct types of “bulbs” and although not all of these are available in the fall and some are not winter hardy, it is important to mention them to be able to understand their differences.

BULB TYPE	EXAMPLES	DESCRIPTION	HOW TO DIVIDE (after digging up)
Rhizome	Begonia, Calla, Canna, Ginger, Iris, Lily of the Valley, Tuberose	Grows horizontally from the pointed ends. As this bulb matures, it branches and develops other pointed growing ends. Roots grow from the bottom.	Cut the rhizome into sections and ensure each piece has at least one pointed growing tip.
Tuber	Anemone, Caladium, Cyclamen, Potato, Tuberous Begonia	Buds and roots form anywhere on the surface. Tuber continues to enlarge with more eyes and roots. No basal plate or growing point.	Cut the tuber into sections with at least one growing bud and root on each section
Tuberous Roots	Clivia, Dahlia, Daylily, Liatris, Sweet Potato	Actually a swollen root, new tuberous roots grow in a cluster from the base of the plant’s old stem or central crown.	Divide the root cluster so each division includes roots and one or more growth buds from the stem base.
True Bulb	Allium, Hyacinth, Lily, Daffodils, Snowdrops, Tulips	Roundish shape with a pointed tip, covered with scales, and has flattened base plate where roots form. May have a papery outer skin. Forms little bulbs, “offsets” at base.	Separate small offsets and plant individually.
Corm	Crocosmia, Crocus, Freesia, Gladiolus	Similar in shape to true bulb however there are no scales. Covered by a “tunic” of fibers. A corm decomposes each year; a new corm develops on top with smaller corms (cormels) on the sides or along the base plate.	Separate new corms from smaller corms and plant individually.

Using Your Divided Bulbs

Once you’ve successfully divided your bulbs and bulb-like flowers, what do you do with your extra bulbs? There are many great options…

Transplant them into different parts of your yard to create a uniform, coordinated landscape with similar plants.
Give them away to neighbors, family members, friends, coworkers or anyone who would like to add new flowers to their yard.
Donate them to churches, schools, parks, senior centers or other places where extra flowers for landscaping will be appreciated.

As your bulbs continue to multiply, you will enjoy having more and more to choose from to create your ideal colorful, fantastic floral landscape.

Autumn: Why Plant Now?

Although many gardeners plant trees and shrubs in the spring, knowledgeable gardeners plant in the fall to take advantage of all this fabulous season has to offer. But why is fall planting better than spring planting?

Stress Reduction
Transplanting causes stress as plants are removed from containers, balls or established locations and changed to new locations. Planting in the fall, when a plant is entering dormancy and is generally hardier and sturdier, reduces this stress so the plant can thrive.

Establishing Strong Roots
Fall planting “establishes” trees and shrubs by encouraging root growth. Because the soil is still warm, the roots continue to develop until freezing, though the upper parts of the plant are already dormant. When transplanting in the spring, the developed roots are active and delicate tips or rootlets, as well as buds and new leaves, are more easily damaged.

Weather Resiliency
Trees and shrubs planted in the fall are better able to withstand the rigors of the next summer’s heat and dry conditions because they have much longer to develop healthy roots systems and become thoroughly established. This is especially critical in dry climates or areas prone to drought or irregular rainfall.

Faster Maturity
The “head-start” of fall planting results in a larger plant in less time, helping create a mature landscape without waiting for smaller plants to catch up. This can be especially critical when replacing dead or damaged plants in a mature landscape to avoid a gap or uneven look.

Water Conservation
Planting in the fall saves watering time and promotes conservation by eliminating daily watering. Cooler temperatures with the addition of both morning and evening dew contribute greatly to soil moisture availability in fall without as much supplemental watering.

Color Confirmation
Fall is the best time to see a plant’s autumnal color. Planting in the fall eliminates the surprise of the wrong color or unexpected shades that may not coordinate with nearby plants. By planting in autumn, you’ll know exactly what you’re purchasing and planting, and you will be able to match better with your existing landscape.

Saving Money
Last but definitely not least, buying your beautiful trees and shrubs in autumn can save big money. We discount prices on trees and shrubs to create room for holiday season materials and pass the savings on to you. Selection may be more limited later in fall, however, so don’t wait too long to take advantage of great savings.

Autumn can be the ideal time to plant trees and shrubs, whether you are adding to your landscape, replacing plants or starting a whole new look. If you plant in autumn, you’ll be amazed at how lovely your landscape will look next spring.

Plant a Tree This Fall

There are so many reasons to add a new tree to your landscape this fall that it’s hard to find a reason not to.

Just think about it, trees will…

Beautify the Environment
Trees add texture and color to the landscape. They soften the harsh lines of buildings and driveways, while their foliage and blooms add seasonal color changes and variety.

Stabilize Soil
Tree roots prevent soil from blowing or washing away, minimizing erosion and providing protection for the surrounding landscape.

Provide Wildlife Habitat
Trees provide shelter and food for birds and numerous small animals, including squirrels, raccoons, insects and more.

Make Food
Many trees provide fruits, nuts, seeds, sap and berries for human consumption. Wildlife will also rely on the food provided by trees.

Create Oxygen
Through photosynthesis, trees take in carbon dioxide, carbon monoxide, sulfur dioxide and other poisons from our air and release pure oxygen for us to breathe. One tree can produce enough oxygen for 10 humans for one year!

Filter the Air
Trees act as giant filters trapping dust and pollution particles with their leaves and bark until the rain washes the particles away.

Cool the Air
Air will remain several degrees cooler in the shade of a tree canopy. This is accomplished by not only by blocking the sun’s rays but also through transpiration. Tree leave transpire, or release moisture, which cools the surrounding air. A large tree can release as much as 400 gallons of moisture from its leaves daily.

Reduce Utility Bills
Deciduous trees planted on the south and southwest sides of a home will shade the structure during hot summer months and reduce air conditioning or other cooling needs. In the winter, with the leaves fallen, the sun is able to warm the structure, reducing heating bills.

Reduce Noise Pollution
Strategically planted, trees can dramatically reduce the volume of unwanted noise from loud neighbors, nearby businesses or car traffic.

Hide undesirable views
Purposefully sited, trees can camouflage unattractive views and create privacy, providing a natural sanctuary in your yard.

In our area, fall is just about the best time of year to purchase and plant a tree. The soil is warm, air temperature is cool and morning and evening dew increase available moisture to nurture a new tree. Stop in and see our extensive collection, and we can assist you in choosing the tree that is perfect for your landscape and lifestyle needs.

King of the Cold: Ornamental Cabbage & Kale

Looking to add interest to the fall and winter landscape? This year, plant ornamental cabbage and kale for bold textures and vibrant colors.

About Ornamental Cabbage & Kale

Unlike most other annuals and perennials, these two hardy plants improve in appearance after a frost or two, which bring out more intense and brilliant colors in their foliage – perfect as an autumn accent or centerpiece plant. Identified by a number of names including floral kale, decorative kale, ornamental-leaved kale, flowering kale and flowering cabbage, ornamental cabbage and kale are classified as Brassica oleracca (Acephala group). Offering unlimited use in the landscape, these plants have large rosettes of gray-green foliage richly variegated with cream, white, pink, rose, red and purple. Kale leaves are frilly edged and sometimes deeply lobed.

While typical ornamental kale and cabbage varieties are easy to find, you can also try more unusual options, including dwarf varieties as well as upright, taller hybrids that can even be used in cut arrangements.

Using These Attractive Plants

Popular in borders, grouped in planting drifts, or planted in containers for the deck or patio, ornamental cabbage and kale typically grows to 12-18” high and wide, depending on the cultivar. Plant these specimens at least 12” apart in an area with full sun that has moist, well-drained soil. Organically rich soil with proper compost or fertilization is best to provide adequate nutrition for these lush plants. Although they are able to withstand light frosts and snowfalls, ornamental cabbage and kale will typically not survive hard freezes and are best treated as showy annuals.

The best foliage color will occur if ornamental cabbage and kale is planted in early fall as temperatures are cooling, or you can sow seeds 6-10 weeks before the first anticipated frost date – just be sure the seeds have sun exposure in order to germinate properly. These plants are usually attractive in the garden until Thanksgiving or slightly later, or in mild climates they may even last until spring temperatures begin to rise. Hint – when the plants smell like cooked cabbage, it is time to pull them out!

While these plants are superficially similar to the familiar cabbage and kale vegetables popular in salads and other edible uses, it is important to note that ornamental varieties are cultivated for color and shape rather than taste. Keep them out of the kitchen and in the garden instead, and you won’t be sorry!

Audition Some Autumn Bloomers

Extend the beauty of your garden with vivid autumn-blooming perennials. When you think of fall-blooming plants, don’t stop at mums – there are many perennials that can add color to your yard at this time of year.

Top Autumn Bloomers

While there are different autumn-blooming perennials for different growing zones and climate conditions, some of the most popular and widespread options include…

Fall Daisies
For fall daisies (besides daisy mums!) grow Boltonia or Nippon Daisy. Boltonia is a tall (3-4′) grower, suitable as a background plant. White or pink daisies are borne in profusion atop fine grey-green foliage. The Nippon Daisy (Chrysanthemum nipponicum) is covered with large crisp white daisies in October. Both love lots of sun and make excellent cut flowers.
Autumn Sedums
Bold-foliaged sedums provide texture as well as color in a sunny place. Sedum ‘Autumn Joy’ is the most well known. It has coppery-pink flower heads. Sedums ‘Brilliant’ and ‘Stardust’, with soft pink and white flowers respectively, are also attractive. For a totally different color combination plant sedum ‘Vera Jameson’. It has gray-purple foliage with rose pink blooms and looks stunning when planted with Blue Fescue, Artemesia Silver Mound and other silver-foliaged plants. As an added bonus, all the sedums are attractive to butterflies.
Autumn Asters
Asters are another fall bloomer that butterflies love. These perennials like sun and moist, well-drained soil. There are many colorful aster varieties in shades of pink, purple, blue and white. Some favorites include tall-growing aster ‘Alma Potschke’ with bright pink flowers, blue-flowered aster ‘Professor Kippenburg’ and low-growing aster ‘Purple Dome’ with its deep purple blooms.
Autumn Goldenrod
Sunny yellow goldenrod (Solidago) is another bright addition to the fall garden. Wrongly blamed as the cause of fall allergy problems, goldenrod has rightly taken its place in the fall garden. It looks particularly effective combined with blue flowering plumbago, purple asters and ornamental grasses.

Fall Bloomers for Shade Gardens

Even shade gardeners can enjoy late blooming perennials. Tall growing Japanese Anemones are a stately addition to the perennial garden. Bloom colors range from pure white to various shades of pink, and flowers can be single, semi-double or double blooms. Anemones grow well in light to moderate shade and spread quickly to form large clumps, filling in space vacated by spent summer plants. Turtlehead (Chelone) is another fast spreader for shade. Rose pink flowers cover the tops of the plant from early September to October. For a deeply shaded location, try Toad Lily (Tricyrtis), which has clusters of beautiful cream flowers, spotted with maroon along its upright stems. For light shade, plant Blue Cardinal Flower (Lobelia siphilitica), whose intense blue spikes can be admired from mid-August until frost.

No matter what type of garden you have, the end of summer does not need to mean the end of colorful blooms. Instead, just opt for amazing fall bloomers and enjoy brilliant color even longer!
