Ornamental Grasses

Ornamental grasses can reduce your watering costs, lessen your mowing time and increase the interest level of your garden. No matter what your garden’s needs, there’s a grass to solve it. From short ground covers to tall bamboo, there’s something for every site.

About Ornamental Grasses

Generally defined as “a plant with narrow upright leaves growing from the base,” ornamental grasses come in different sizes, shapes, colors and with differing growing requirements. While they may be cut to the ground each year, they are not mowed regularly, and work well as borders, specimen plants or part of coordinated beds. When choosing an ornamental grass for your site, consider the following:

  • Size
    Some beautiful grasses are just inches tall. Others, such as bamboo, grow to 20 feet or even taller. A shorter grass is a perfect edge for a walkway or to border a flowerbed, while a taller grass provides screening or background height.
  • Deciduous or Evergreen
    The winter form of a grass can be very different from its summer form. Evergreen grasses do not die back in the winter, their form remains the same. Winter colors may change and provide interest. Deciduous grasses die back or lean over. Consider the plant’s use when choosing between deciduous and evergreen. If using a grass as a screen, deciduous may not be a good idea.
  • Running or Clumping
    Clumping grasses stay where they planted, and as they grow, the overall plant width increases. However, a running grass sends runners through the ground to grow another grass plant. Sometimes this can be up to 6 feet away. This is advantageous when using the grass as a groundcover or trying to fill in a larger area. Clumping grasses can be divided if they become too large for the site.
  • Color
    Ornamental grasses are available in many colors, including variegated shades with contrasting edges. Additionally, many grass colors change throughout the year. Blues, reds, greens, yellow and variegated shades work well in different situations. A gold or white-hued grass can brighten a dark corner, whereas a dark green grass may be a perfect backdrop for smaller colorful plants.
  • Growing Requirements
    Sun, water, wind and soil requirements vary among grasses. Some require full sun; others grow best in the shade. Some grasses are ideal in rain gardens or wet soils, while others thrive best in drought conditions. Some don’t mind a breezy location, while others need to be more protected. Some prefer a rich, organic soil, while others will look great even in poor soils. And, of course, there are grasses for every range in between.

Before going to the garden center to purchase an ornamental grass, make a list of your requirements. You may want a short grass to line a walkway in full sun with sandy soil. Alternatively, you may need a grass to fill a dry and shady corner. Perhaps you would like to watch a grass clump emerge in the spring, grow to 6′ tall, change colors through the summer and harvest dry seed heads for an autumn arrangement. Choosing the correct grass ensures the beauty of your garden for years to come.

Caution in the Garden… Chlorosis

Yellow means caution, even for plants. While leaf yellowing, known as chlorosis, may be a signal that there is a problem that requires attention, it may also be normal. Understanding when this coloration is to be expected and when it indicates a problem is essential to be sure you’re giving your plants the proper care.

The Good and the Bad About Chlorosis

Chlorosis is the scientific word used to indicate the full or partial yellowing of plant leaves or stems and simply means that chlorophyll is breaking down. There are times when this is normal, expected coloration, and there are times when it indicates deeper problems that need attention.

  • Normal Chlorosis – Yellowing leaves at the base of an otherwise healthy plant is normal; the plant is simply utilizing the nitrogen and magnesium for exposed leaves near its top rather than older, lower leaves. These yellowed, older leaves will eventually shrivel and fall off as newer growth emerges at the top of the plant.
  • Chlorotic Response to Light – Moving a plant from full sun to shade, or visa-versa, can cause yellowing leaves as the plant reacts to the change and stress. Make sure that you grow and maintain your plant in the proper light. Also bear in mind seasonal changes that may affect how much light a plant is exposed to, even if it hasn’t been moved.
  • Chlorotic Response to Moisture – Sudden changes in soil moisture may damage or kill plant roots which can lead to yellowed leaves as the roots are unable to take up sufficient moisture. Most otherwise healthy plants, however, are able to grow new roots as they readjust. Maintain correct soil moisture or move the plants to a more favorable environment.
  • Mineral Deficiency – A shortage of some key mineral nutrients will cause chlorosis in plants. Often, a yellow leaf indicates a lack of nitrogen, however, magnesium, iron, sulfur or manganese deficiencies are indicated by yellowing leaves with prominent green veins. A magnesium deficiency will manifest itself in the yellowing of older leaves. On the other hand, an iron deficiency presents itself in the yellowing of new or young leaves. A simple soil analysis will let you know what minerals or trace elements your soil is deficient in.
  • Soil Factors – Although essential and trace elements may be present in the soil, many other factors affect how the plant uses and absorbs them. If the soil pH is too high/low or there is too much salt in the soil, the plant will not be able to utilize the available nutrients. Test your soil pH and adjust as necessary to be sure the plant can absorb nutrients appropriately to maintain proper foliage colors.
  • Toxins – Although this doesn’t happen frequently, pollutants like paint, oil, chemical solvents, airborne herbicides or pesticides or other pollutants may cause leaves to turn yellow and dark brown before dying. In this case, remove and dispose of the plant and its surrounding soil, and mark the area to be sure it can be treated appropriately and no other plants are inadvertently exposed to the toxins.

It can be alarming to see healthy plants suddenly yellowing, but by understanding chlorosis and how it happens, you can take steps to determine the cause of the color change and what to do to help your plants recover.

Spider Mites

Spider mites are one of the most common pests in landscapes and gardens and feed on many fruit trees, vines, berries, vegetables and ornamental plants, as well as houseplants. These tiny mites are just large enough to be seen with the naked eye, but may just look like tiny, moving dots. For tiny creatures, they can do considerable damage to plants if left unchecked.

How Spider Mites Hurt Plants

Spider mites cause damage by sucking cell fluids from plant leaves. A small number of mites usually isn’t a reason for concern, but plants can sustain heavy damage if populations are high and the infestation spreads. You may notice a stippling of light or yellowish spots on affected leaves and often the webbing of mites can be seen on leaves and stems. As the damage continues, leaves may turn completely yellow, dry up and fall off the plant.

Controlling Spider Mites

Spider mites reproduce rapidly in hot, dry weather, therefore, keeping plants well watered is a good deterrent to heavy infestations. There are also many natural enemies to these pernicious bugs, such as lacewing larvae and some lady beetles that help to keep mite populations under control. Cultivating these helpful insects may be all that is necessary to minimize spider mite activity unless the infestation has already increased and spread.

Because spider mites are too tiny to pick off infected plants, judicious pruning or trimming of infested plants can help remove these pests. In heavy infestations, it may be necessary to discard an entire plant to take the mites with it. Do not put these clippings or removed plants in compost piles, however, or the mites will continue to thrive and will return to healthier plants.

At times, it may be necessary to use chemicals to deter spider mites. Be careful when using broad spectrum insecticides, however, as these will kill any beneficial insects as well as the spider mites, which can disrupt the delicate balance of a garden’s ecology. Simply spraying plant leaves with a blast of water, taking care to spray the undersides as well, can help to reduce mite populations by physically removing the spider mites. Insecticidal soaps and neem oil are also good choices when dealing with spider mites.

Once the mites have been removed, damaged plants may look bedraggled, but they will generally recover within a season or two, especially if the pests were recognized and treated quickly. Don’t let spider mites catch you in their webs – get rid of them today!

Heavenly Hosta

Hostas are amazing plants, truly glorious with heavenly foliage that is stunning as a specimen or in mass plantings. The thin spikes of purple or white, trumpet shaped flowers appear for several weeks in the summer and are an added benefit to this divine perennial. But how much do you know about hostas, and which can you add to your landscape?

Phenomenal Foliage

Hostas are praised by many for their magnificent variety of leaf sizes, colors and textures. These angels will grace your garden with heart-shaped, lance-shaped, oval or nearly round leaves, and leaf sizes vary as well. Smooth, quilted or puckered textures, with either a matte or glossy sheen, add to the glory and hostas’ radiant glow.

The leaf margins can be either smooth or wavy and range in color from light to dark green. Foliage colors also include chartreuse, gray and blue, depending on the cultivar. Variegated hostas with cream, white or yellow margins will radiate in a dark area of your garden.

Where to Plant Hostas

While most hostas are shade worshippers, some types will tolerate sun, depending on the overall climate and moisture levels. Hostas remain attractive from spring until frost and can withstand a wide range of growing conditions.

As choice groundcovers or single specimens in the landscape, hostas are certainly divine. Some hostas are quite unusual and rare and may increase in value each year, especially as the plants thrive and can be divided and transplanted with ease.

Best Hosta Care

Little maintenance is required to care for hostas. Cut off old flower stalks after flowers have faded. Divide plants occasionally to increase their quantity. Keep an eye out for pests, especially slugs and snails that munch on the foliage.

Types of Hostas

With so many selections and varieties, you can find a hosta the will fit into almost any garden situation. The most popular options include…

  • Dwarf & Small Hostas: In addition to being planted in secret little pockets throughout your garden or next to paths, dwarf and small hostas can be used in difficult places. Plant them among tree roots, on a slope or terrace or in rocky places containing little soil.
  • Edger Hostas: These hostas are 12” or less in height and have more horizontal growth. They are able to control weeds as they leave no light, when well established, or room for weeds to grow.
  • Groundcover Hostas: This group of hostas grows to 18” or less in height. They do a great job in areas difficult to weed or maintain. If you are in need of a hosta for use as a groundcover, keep in mind it works great to plant spring-flowering bulbs among them. The hosta comes up after the show of flowers and covers the fading foliage of the bulbs.
  • Background Hostas: Selections from this group grow to 24” or taller at maturity. They can be used to increase privacy where you sit and relax or to provide definition to your property line as a unique hedge.
  • Specimen Hostas: Specimens may be any size. Choose a site close to where the plant will be viewed so that every detail (texture, color pattern, buds, flowers and fragrance) may be enjoyed.

Not sure which hosta is right for you? Come in today and let our landscape and garden experts help you choose the right heavenly hosta to add a bit of the divine to your yard!

New Shrub Raspberries

Rejoice! You no longer need hedgerows, trellises or complicated stakes to grow succulent raspberries. You won’t need armor-like gloves either. Now you may grow thornless raspberries in your garden or in containers on your patio, deck or front porch.

Introducing Raspberry Shortcake™

Developed in Oregon after decades of intense breeding for the most desirable plant characteristics, Raspberry Shortcake™ (Rubus idaeus ‘NR7’) is the first truly dwarf raspberry. Growing just 2 ½ to 3 feet tall with a compact, mounding shape, it is covered with full-sized sweet raspberries from mid-summer through fall. Deciduous in the winter, it produces new canes in the spring to bear even more fruit. It is self-fertile so does not require multiple plants to bear fruit, but its size, appearance and juicy berries are too good to plant just one.

Planting Your Raspberry Shrub

Well-drained, rich soil produces the best and most abundant fruit from these shrubs, and neutral pH (7.0) is preferred. If planting in a container, be sure to use a potting mix especially for containers to ensure adequate nutrition to the plant. If planting in the landscape, choose a location in full sun with moderate room suitable for some spreading, such as bordering a hedge or along a walkway that will help guide the growth and expansion. Water regularly for plump, juicy berries. A well-balanced fertilizer in early spring and summer increases plant vigor and production.

Pruning is simple, just remove the oldest canes after fruiting and enjoy the fruits on the new ones in spring. Avoid trimming away new growth, or you may miss out on future harvests, but any dead canes can easily be pruned away to keep the plant healthy and productive, as older canes will not produce new fruit.

Protecting Your Berries

It is important to note that these berries can be just as irresistible to birds and other backyard wildlife as they are to gardeners of all ages and abilities. To protect the berries so there are some left for you to enjoy, it may be necessary to use netting or other types of covers over the shrubs after the berries first appear in the summer. After the fruiting is finished, the covers can be removed.

Raspberry Shortcake™ is so simple, safe and easy, it doesn’t matter what color your gardening thumb may be, what experience you have harvesting berries or even if you’ve never grown anything to eat before – even young children can grow and harvest these mouth-watering raspberries with ease!

General Soil Amendments

We’ve all heard of the importance of amending the soil properly for gardening and landscaping, but the number of soil amendments sold in garden centers often confuses gardeners. Which is which, and which will work best for your soil conditioning needs?

Types of Soil Amendments

Soil amendments fall into two basic categories, inorganic and organic. Inorganic amendments come from non-living materials such as sand, perlite, vermiculite and crushed stone. With the exception of limestone and gypsum, which are used to increase soil calcium, these are not commonly used in the garden.

However, organic amendments are the opposite. They come from previously living materials such as peat, manures and composts. When leaves, bark, peat, animals and animal wastes are mixed together to decompose, compost or “humus” is the final product. Very commonly used, these materials enrich the soil by increasing the air spaces, adding extra nutrients to the soil, improving the absorption of those nutrients and increasing overall soil fertility.

Why You Need Soil Amendments

Excellent soil is not common around most homes. Even if it was initially, house construction and roadwork often removes the good soil and construction equipment compacts the remaining soil. Furthermore, heavy use of the remaining turf – children and pets playing, for example – continues to compact the soil. Chemical treatments, runoff from gutters and downspouts, removal of existing plants, changes in local wildlife – all of these factors can wreak havoc on soil.

Adding organics loosens compacted soil and results in better gardens. Incorporate organics into the beds throughout the year by working evergreen needles, leaves and lawn clippings into the soil. Amendments such as peat or lime can improve a pH problem, if one exists. Calcium and magnesium deficiencies can be corrected using organic materials such as bone meal or wood ashes, or inorganic materials such as limestone, gypsum or soft rock phosphate.

Mulching is another simple way to add biodegradable materials to the soil. Simply place mulch around the plant, leaving several inches bare closest to the stem to discourage insect invasions and rot. In addition to slowly providing nutrients as it decomposes, mulching is attractive, reduces weeds and erosion, maintains soil temperature and prevents “crusting” that occurs when soil becomes too dry.

Another advantage of adding organics is the attraction of worms. They further assist in the decomposition, increase aeration and leave worm castings, a valuable organic material, behind. A healthy garden is home to many worms, and it all starts with adding organic soil amendments.

Whether you opt for organic or inorganic soil amendments, if you use them properly, you soil will improve and your landscaping, flowerbeds and garden will look better than ever.

Let Me Out! Moving Houseplants Outside for the Season

Are your house plants looking a little peaked after a long winter of being cooped-up inside? Getting out for some fresh air during the warm months is healthy for all living things, including your potted plants. It is important to move plants safely and thoughtfully, however, or else you risk shock and damage that can destroy your carefully cultivated houseplants. With the right steps, you can move your houseplants to outdoor accommodations for the spring and summer while still protecting them from unfavorable conditions, pests and wildlife.

Tips for Moving Houseplants Outdoors

When you are ready to move your houseplants outside…

  • Wait until there is no longer any danger of freezing or frost before setting houseplants outside.
  • Before you place plants outdoors, acclimate them to the spring temperatures. Set them outside for short periods of time and bring them inside at night.
  • Over a period of two weeks, lengthen the plants’ outdoor exposure time gradually. Continue to bring plants inside at night if temperatures are not consistently above 55 degrees Fahrenheit.
  • Do not place plants directly in the sun or else the leaves may burn.
  • Set plants on pot feet or a suitable plant stand to prevent sow bugs.
  • Arrange plants in groups for increased humidity, being careful to promote good air circulation within the foliage.
  • Check soil often for moisture levels, as warmer days and breezes may dry pots out more quickly.
  • Empty saucers of excess water to prevent root rot and minimize standing water that will attract biting insects.
  • While away on vacation, use a self-regulating plant watering system.
  • Mulch the surface of the soil to retain moisture and keep weed seeds from invading the soil.
  • Keep squirrels from digging in pots by placing a layer of crushed oyster shells or chicken wire on top of the soil.
  • Use a slow-release fertilizer to save you time and energy on frequent fertilizing. Or, use a water soluble fertilizer every other week. Follow the manufacturer’s instructions so as not to burn tender plant roots.
  • Groom plants by clipping off damaged stems, yellow leaves and spent flowers. This will also improve air circulation and sunlight reach.
  • Trellis or stake plants that get too tall to prevent them from flopping over.

As they enjoy their time outdoors, you’ll see healthier, more robust houseplants with plentiful new growth and vigor. Why not give all your plants a great spring and summer getaway by moving them outdoors?

Growing and Containing Rampant Spreaders

What do you do when you fall in love with a plant but you know it spreads and could take over your entire garden? You don’t have to give up your hopes of nurturing this plant, you just have to learn how to contain it securely without destroying its beauty.

Favorite Spreaders

Many different plants may be desirable, but have the nasty hidden personality of spreading out of control. Common spreaders that are still garden favorites include…

  • Mint
  • Lamb’s ears
  • Lily-of-the-Valley
  • Beebalm
  • Loosestrifes

Any plant that is labeled as “fast growing” or “aggressive” can potentially take over a garden space and should be treated with caution if you want to keep it contained.

Literal Containing

Containing a known spreader could be as easy as planting it in its own container. Ceramic, metal or resin pots certainly put a punch of color in a corner, on a deck or by the front entrance. They’re also great for adding plant height and focal points in the garden, and they will ensure the plant stays put.

Perhaps a touch of whimsy would add pizzazz to your garden while controlling your marauder. Picture your potential runaway planted in a pot, “sitting” in a hole cut in the seat of a painted and weather-sealed wooden chair. This creates a colorful garden focal point, elevates your beauty and keeps it from spreading. Another quirky option is to use an old, rusty wheelbarrow as the container and position it near the garden or inside a flowerbed. It can be fun to get creative with container options, all of which will help you enjoy your favorite spreading plant without letting it get out of control.

Containing Plants in the Garden

If you want the potential invader in the ground, research the plant well before introducing it to your garden. Different plants require different control measures. Mowing to eliminate new growth controls some plants. Herbicide applications can have an effect on others, while some require hardscaping to control their roots and keep them in place. Some plants may not give in easily to any control methods.

For the Most Vigorous Runners

In cases where plants are nearly assured to take over without proper control methods, trench containment may be the best option.

  • Determine where you would like to plant, bearing in mind the needs of the plant for proper sunlight, moisture and soil condition.
  • Dig a trench 26-30 inches deep along the boundary of the planting area that you wish to contain.
  • Line this trench with a high-density polyethylene liner, leaving 2 inches of the liner above the soil line.
  • Overlap the end of the liner by at least 6-8 inches to that the plant root cannot escape through the opening.
  • Backfill the trench to secure the liner and hold it firmly in place. If desired, you may fill the trench with gravel or other inorganic material to create another level of containment protection.
  • Plant inside the growing area, taking care not to disturb the containment trench.
  • Periodically, check the edges of the trench liner to be sure the roots don’t try to climb over the barrier. If they are, be ruthless and cut them back.

Left to their own devices, vigorously spreading plants can quickly become a nightmare as they take over a garden or landscape. If you know how to contain these plants, however, your dreams of nurturing them in your yard can come true.

Determinate Versus Indeterminate Tomatoes

It’s tomato-planting time again! If you’ve grown tomatoes in the past, you most likely have your favorites. If not, just ask! You’ll find some pretty strong opinions regarding tomato choices, and every gardener has their own top choices, must haves and great picks for tomatoes.

Choosing Tomatoes

Along with soil type, climate, moisture and other typical gardening considerations, one of the features you will need to take into account when choosing what type of tomato to grow is plant habit. The two main habit classifications are “determinate” and “indeterminate” and are based on fruit use, available growing space and length of growing season. Both habit classifications include fruit selections in a wide variety of colors, sizes, shapes and tastes.

Determinate Tomatoes

Tomatoes from a determinate plant are produced earlier in the growing season, on terminal ends of a compact bush. This type of tomato generally reaches 3-4 feet in height and is easily supported with a tomato cage or may even be self-supporting. Due to its compact habit, it may even be grown in containers, ideal for gardeners with less available space. Because all the fruit ripens at the same time, determinate tomatoes are an excellent choice if you plan to can your fruit or make sauce, as you won’t need to worry about collecting enough fruit to work with. Determinate classification includes popular tomato varieties such as:

  • “Celebrity” – an eating/slicing tomato
  • “Roma” – a paste tomato
  • “Sugary” – a cherry tomato
  • “Carolina Gold” – extra large, yellow fruit

Indeterminate Tomatoes

Indeterminate tomato plants will fruit along the entire length of the stem over a longer period of time, in fact continually, until frost. Smaller amounts of fruit ripening regularly throughout the growing season makes an indeterminate tomato plant an excellent choice if you cannot cook or consume a large quantity of this perishable fruit all at one time. Indeterminate tomato plants are vines, requiring proper pruning and support, to reach their ultimate height of 8 feet or more. Indeterminate classification includes popular varieties like:

  • “Amish Paste” – heirloom, paste tomato
  • “Beefmaster” – extra large sandwich tomato
  • “Better Boy” – juicy but firm, compact vine with shorter internodes
  • “Black Krim” – deep color, rich flavor
  • “Chocolate Cherry” – cherry, chocolate red in color

By understanding the differences between these basic tomato classifications, it will be easy for you to choose the tastiest tomato to suit your gardening needs and harvest preferences. Many gardeners choose more than one of each type of tomato, ensuring there is always a bountiful supply to use, to share and to enjoy!

Summer Sizzles With Crocosmia

There is an excellent assortment of bulbs available for planting this time of year that promise a bounty of summer blooms. The thing is, many of these bulbs are not winter hardy. This can create a predicament for gardeners anxious for easy summer flowers but short on time and space to dig and store tender bulbs. Crocosmia can be the answer.

Introducing Crocosmia

Native to South Africa, Crocosmia – also known as montbretia, coppertips or falling stars – sizzles all summer long in colors of yellow, orange and red. The numerous small florets are tubular in shape and borne along a long, gracefully arching stem rising above sword-like foliage. Together, this formidable combination creates exotic elegance sure to be a showstopper in the garden or landscape. Hummingbirds and butterflies also find it irresistible when in bloom, and the fall seedpods are delectable for many seed-loving finches and sparrows.

Planting Crocosmia

Plant Crocosmia corms now, while they are available. Plant them in well-drained soil in full sun, 2-3 inches deep and 8-10 inches apart. A south-facing location is best, or in colder regions, add Crocosmia next to a wall that will help warm the soil. The pointy side of the bulb should be facing up. Place a handful of bone meal in the planting hole and water the soil well when done planting. These are drought-tolerant flowers, but supplemental water will still be welcome in extremely dry conditions.

Crocosmia look best when planted en masse. A grouping on either side of a sunny entrance way can be stunning, and they look equally fetching when tucked into the perennial border. This plant performs well in containers and makes an excellent cut flower – in fact, cutting the flowers will encourage even more beautiful blooms to form.

Blooms will first appear in May or June and will continue blooming throughout the summer. Flower spikes can stretch 2-3 feet tall, adding a bold burst of color to the landscape. Even without the flowers, the blade-like foliage is attractive, and some cultivars show pleats or rippling for more textural interest.

After flowers have finished blooming, simply snip off the faded flower stalks. Leave the foliage to fade naturally as you would with any other bulb. These leaves continue to produce food to provide nourishment for next year’s flowers. Leaves may be cut back to the ground once they are completely yellow, and a thick layer of mulch should be added for winter protection. Once established, these bulbs are winter-hardy and will return year after year to heat up the spring and summer with their gorgeous colors and forms.
